It is classified according to the structures of their hydrophilic groups: oil soluble surfactants and sulfates, which are the main types of anionic surfactants. The various functions of surfactants are mainly manifested in changing the properties of the liquid surface, the liquid-liquid interface and the liquid-solid interface.</p> <p>Sodium Laureth(2) Sulfate (AES/SLES)<br /> Chemical Formula: C12H26Na2O5S<br /> CAS No.: 68585-34-2<br /> Dangerous Grade: Non-dangerous</p> <p>Sodium Alpha Olefin Sulfonate (AOS-35)<br /> Chemical Formula: R-CH=CH-(CH2)n-SO3Na<br /> CAS No.: 68439-57-6<br /> Dangerous Grade: Non-dangerous</p> <p>C12-14 Linear Alkyl Benzene Sulfonate(LAS)<br /> Chemical Formula:C18H30O3S<br /> CAS No.:27176-87-0<br /> Dangerous Grade: 8</p> <p>Common anionic surfactant:<br /> Sulfate, sulfonate, and phosphate esters<br /> Anionic surfactants contain anionic functional groups at their head, such as sulfate,sulfonate, phosphate, and carboxylates. Prominent alkyl sulfates include ammonium lauryl sulfate, sodium lauryl sulfate (sodium dodecyl sulfate, SLS, or SDS), and the related alkyl-ether sulfates sodium laureth sulfate (sodium lauryl ether sulfate or SLES), and sodium myreth sulfate. Carboxylates are the most common surfactants and comprise the carboxylate salts (soaps), such as sodium stearate. More specialized species include sodium lauroyl sarcosinate and carboxylate-based fluorosurfactants such as perfluorononanoate, perfluorooctanoate (PFOA or PFO).</p> <p>Anionic surfactants take many advantages in mature production process, great availability of raw materials, and a wide range of applications. Therefore, it is widely used in many fields such as agriculture, industrial cleaning, textile printing and dyeing, and household chemicals.</p> <p>1. Agriculture<br /> The use of anionic and non-ionic formulations as pesticide emulsifiers can reduce the usage of emulsifier from 20% ~40% to 3% ~ 10%. This will help improve the chemical stability of pesticides, while reducing costs, pollution,so ensure the efficiency of utilization. In addition, alkylbenzene sulfonates, lignosulfonates are often added into insecticides, rust removers, and plant growth regulators as emulsifiers and wetting agents to improve soil quality.</p> <p>2. Construction industry<br /> In architectural coatings, surfactants primarily act as wetting, emulsifying, dispersing, stabilizing and antistatic agent.</p> <p>3. Cosmetics industry<br /> The use of anionic surfactants in cosmetics has become more widespread in recent years and its main role is as emulsifiers, solubilizers, wetting agents and effective component synergists.</p> <p>4. Oil field industry<br /> Surfactants play an important role in the chemical oil displacement process. They can reduce the oil/water interfacial tension and increase the number of capillary tubes, thereby greatly improving the oil recovery.</p> <p>5. Textile industry<br /> Many processes in the textile printing industry require the use of a large amount of surfactants. For example, a large number of anionic surfactants with cleaning performance are used in the pretreatment process, anionic surfactants with infiltrating performance are used in the dyeing and finishing processes. In addition, some functional products such as leveling agents, fixing agents, etc., are also of anionic type.</p> <p>6. Daily chemical industry<br /> Anionic surfactants are widely used in daily chemicals. The most common application is soap. The main ingredient is sodium stearate. Anionic products have the characteristics of high foam and delicate performance, low price and so on, which can reduce the cost of the liquid detergent and other products, as well as improve the product transparency.</p> <p>Now the price of anionic wetting agent is reasonable, if you have needs to buy anionic agents, please contact us.</p> <p>If you want to buy Allyl Glycidyl Ether, please leave us a message.<br /> <a href="https://njchm2020.weebly.com/uploads/1/3/4/0/134034191/7-1_orig.png" rel="nofollow"><img src="https://njchm2020.weebly.com/uploads/1/3/4/0/134034191/7-1_orig.png" alt="7-1_orig.png" /></a></p> 2024-05-20T15:46:38+0900 http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/xKf6nSjrg6t njchm http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/xKf6nSjrg6t#comments http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/xKf6nSjrg6t Amphoteric Surfactant(2024年05月24日) <p><a href="https://www.njchm.com/products/amphoteric-surfactant/">https://www.njchm.com/products/amphoteric-surfactant/</a></p> <p>Amphoteric surfactants are surfactants that contain both an anionic hydrophilic group and a cationic hydrophilic group in the same molecule. The most important feature is that it can both give and receive protons. It has the following characteristics: excellent softness and smoothness and antistatic properties for fabric; certain degree of bactericidal and anti-mildew function; good emulsifying and dispersing properties. It is a mild surfactant. Amphoteric surfactants differ from single anionic and cationic surfactants in that both acidic and basic groups exist at one end of the molecule. Most of the acidic groups are carboxyl, sulfonic or phosphoric acid groups, and the basic groups are amine groups or quaternary ammonium groups. They can be compounded with anionic and nonionic surfactants and are resistant to acids, alkalis, salts and alkaline earth metal salts.</p> <p>Amphoteric Surfactant List</p> <p>Cocamido Propyl Betaine (CAB-35)<br /> Chemical Formula: C19H38N20<br /> CAS No.: 61789-40-0<br /> Dangerous Grade: Non-dangerous</p> <p>Cocamido Propyl Hydroxyl Sultaine (CHSB-35)<br /> Chemical Formula: C20H42N2O5S<br /> CAS No.: 68139-30-0<br /> Dangerous Grade: Non-dangerous</p> <p>The lecithin in the egg yolk is a natural amphoteric surfactant. Nowadays, artificial amphoteric surfactants are commonly used, and the anion part thereof is mostly a carboxylic acid group, and a few are a sulfonic acid group. Most of its cations are amine salts or quaternary ammonium salts. Ammonium salts constitute the amino acid type, and quaternary ammonium salts form the betaine type.</p> <p>Amphoteric surfactants can be effectively applied to mild, biodegradable and highly efficient home or industrial utility cleaning formulations, and any application of amphoteric surfactants has a lot to do with synergy. The mildness and moderate cleanliness of the amphoteric surfactants are better than conventional soaps and can, therefore, be used well in hand sanitizers. Its stability at high pH values is very beneficial for its use in metal cleaning. Amphoteric surfactants are used in other industrial cleaning agents such as high-pressure cleaners, traffic fouling removers and foam cleaners as ome of the dirt cannot be completely removed by mechanical flushing. Nonionic surfactants are commonly used as penetrants and lubricants in such cleaners. They do not interact directly with normal soiled membranes, but it is possible that a synergistic effect occurs.</p> <p>Now the price of amphoteric detergents is reasonable, if you have needs, please contact us.</p> <p>If you want to know more about glycolic acid, please visit our website.<br /> <a href="https://njchm2020.weebly.com/uploads/1/3/4/0/134034191/5-1_orig.png" rel="nofollow"><img src="https://njchm2020.weebly.com/uploads/1/3/4/0/134034191/5-1_orig.png" alt="5-1_orig.png" /></a></p> 2024-05-20T15:45:45+0900 http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/rZxeWOKLAFB njchm http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/rZxeWOKLAFB#comments http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/rZxeWOKLAFB Ammonium Iodide(2024年05月23日) <p><a href="https://www.njchm.com/products/ammonium-iodide-cas-12027-06-4.html">https://www.njchm.com/products/ammonium-iodide-cas-12027-06-4.html</a></p> <p>Ammonium Iodide</p> <p>Features of Ammoniumiodid<br /> Product Name: Ammonium iodide<br /> Chemical Formula: NH4I<br /> CAS No.: 12027-06-4<br /> Dangerous Grade: NO<br /> Technical Data of Ammonium Iodide</p> <p>ItemSpecificationResult<br /> AppearanceWhite crystalline powderWhite crystalline powder<br /> Assay(NH4I), %≥99.599.7<br /> Insolublity, w/%≤0.0050.004<br /> Chloride(Cl), w/%≤0.02<0.02<br /> Iodate and iodine(IO3),w/%≤0.01<0.01<br /> Iron(Fe), %≤0.0003<0.0003<br /> Residue on ignition(as sulfate), w/%≤0.020.01<br /> Conclusion: Pass</p> <p>Package and Storage:<br /> 25kg/drum<br /> Store in a cool, dry place.

In phosphate-free washing powders with LAS and AOS as anionic active ingredients, the detergency of AOS is significantly increased when the active content is more than 20%. The detergency synergy of AOS in non-phosphorus washing powder is more oustanding than that in phosphorus-containing powder. AOS has a good compatibility with enzyme. The detergency power of AOS and LAS is not much different at high temperatures and long-term washing (eg above 60°C, washing for 1 hour). However, AOS shows higher detergency performance than LAS when used under room temperature (10-40°C for 10-29 minutes). Compared with LAS, AOS features stronger hard water resistance. AOS shows a very good stain removal performance on sebum dirt and oily and powdery stain.</p> <p>Application of soap<br /> Adding AOS can increase the solubility of soap in water, wetting power and foam strength of soap at low temperatures can also be increased significantly It improves various properties of the soap, enhances foaming power, increases hard water resistance and flexibility.</p> <p>Liquid detergent application<br /> Due to the greater irritation of LAS, many detergents do not use LAS as an active ingredient, while AOS has a low irritative property and good biodegradability, making it a more suitable alternative.</p> <p>Personal care application<br /> The mildness of AOS is comparable to that of AES, while LAS and AES are much more irritating than AOS. Thus AOS has a wide range of use in personal care products. AOS is extremely stable under acidic conditions, and normal human skin is weakly acidic (pH about 5.5), so it is suitable to use AOS as a component of personal washing products. Shampoos with AOS as the main active ingredient are more foamable than with K12.</p> <p>Other applications<br /> AOS has a wide range of applications in the textile printing and dyeing industry, petrochemicals, tertiary oil recovery, and industrial cleaning. It can also be used as a concrete density improver, foam wallboard, fire-fighting foaming agent.

The dibasic acid is phthalic acid or phthalic anhydride or an ester thereof, adipic acid, halogenated phthalic acid or the like. The polyhydric alcohol is ethylene glycol, propylene glycol, diethylene glycol, trimethylolpropane, pentaerythritol or the like. Different types of polyester polyols have different properties due to different types or different preparation processes. Several indicators that are important for polyester polyols are hydroxyl number, acid value, moisture, viscosity, molecular weight, density, and color. Characteristics and uses of polyester polyols: Polyester-based polyurethane contains a large number of polar groups such as ester groups and amino groups in the molecule, and has strong cohesive strength and adhesion, and has high strength and wear resistance.</p> <p>Polyether polyol (referred to as polyether) is composed of an initiator (active hydrogen group-containing compound) and ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO), etc. in the presence of a catalyst. It is obtained by polyaddition reaction. The largest yield of polyether is glycerol (glycerol) as the initiator and epoxide (usually PO and EO). Various general-purpose polyether polyols are produced by changing the feeding mode of PO and EO (mixing plus or separately adding), the ratio of addition, the order of addition, and the like.</p> <p>If you want to know more applications of glycolic acid, please visit our website.</p> <p><a href="https://www.njchm.com/storage/202007/jpg/Polyether%20Polyol.jpg" rel="nofollow"><img src="https://www.njchm.com/storage/202007/jpg/Polyether%20Polyol.jpg" alt="Polyether%20Polyol.jpg" /></a></p> 2023-01-20T15:45:23+0900 http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/KD8HeKUyKOW njchm http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/KD8HeKUyKOW#comments http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/KD8HeKUyKOW Polyether Polyol Manufacturing Process(2023年01月20日) <p><a href="https://www.njchm.com/service/polyether-polyol-manufacturing-process.html">https://www.njchm.com/service/polyether-polyol-manufacturing-process.html</a></p> <p>Synthesis of DMC-based polyether polyol by a continuous method</p> <p>A certain amount of DMC catalyst is taken and uniformly dispersed in a certain amount of small molecule initiator.

Preparation of ethyl bromide from ethyl alcohol and hydrobromic acid<br /> Start with a 1-liter double neck round bottom flask with a drop funnel and wide bend. The bend is connected to a long and efficient condenser assembly and receiver for downward distillation. First, place 281ml (or 415 g) 48% hydrobromic acid in a flask, then add 65ml (or 120 g) of concentrated sulfuric acid in batches, while shaking. As it cools, a small quantity of 145ml (or 100 g) 95% ethanol is slowly added to the mixture of sulfuric acid and hydrobromic acid. Then 109ml (or 200g) of concentrated sulfuric acid is slowly added to the drop funnel, and the ethyl bromine obtained by slow distillation is collected in the cold receiver flask. The crude ethyl bromine was washed with equal volume of concentrated hydrochloric acid, then washed with water and a small amount of 5% sodium bicarbonate solution, then washed with water, and finally dried the ethyl bromine with anhydrous calcium chloride. The crude ethyl bromide is purified by distillation and 205 grams of pure ethyl bromine is obtained.</p> <p>2. Preparation of ethyl bromide from ethyl alcohol and potassium bromide<br /> Add 50g of concentrated sulfuric acid to 25g of ethanol and let it cool under continuous stirring. Pour in 60g of powdered potassium bromide and let the mixture rest overnight. The next day, the ethyl bromine is distilled and washed, washed with dilute sodium carbonate solution and water. Finally, the obtained bromoethane was dried and re-steamed with calcium chloride.</p> <p>3. Preparation of ethyl bromide from ethyl alcohol and bromine<br /> Place 60g of ethanol and 10g of red phosphorus in a round bottom flask cooled with cold water. Then 60g of bromine was slowly added to the droplet funnel while the mixture was stirred and cooled. When all the bromine is added, stir the mixture for another hour. The ethyl bromide is then distilled and washed with dilute sodium carbonate solution and distilled water. Finally, using calcium chloride ethyl bromide and distillation, got in 38 ℃ boiling colorless heavy liquid.</p> <p>If you want to know more applications of monoammonium glycyrrhizinate, please visit our website.</p> <p><a href="https://www.njchm.com/uploads/image/20180730/18/ncmc-building_1532948384_220x220.jpg" rel="nofollow"><img src="https://www.njchm.com/uploads/image/20180730/18/ncmc-building_1532948384_220x220.jpg" alt="ncmc-building_1532948384_220x220.jpg" /></a></p> 2023-01-20T15:44:13+0900 http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/f3St5vDnTBw njchm http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/f3St5vDnTBw#comments http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/f3St5vDnTBw The Application of Glycolic Acid in the Cosmetics Industry(2023年01月20日) <p><a href="https://www.njchm.com/service/glycolic-acid.html">https://www.njchm.com/service/glycolic-acid.html</a></p> <p>In the salon, the beautician first cleans and rinses the skin area to be treated, and then applies the glycolic acid solution or gel with fingertips or cotton tips or brushes. When treating the face, leave the solution / gel in place for 5-10 minutes, then rinse off with gauze dipped in cold water. Occasionally, use the solution / gel a second time and leave it in place for 5-10 minutes before rinsing. Hand, foot and other body parts are treated similarly.</p> <p>According to industry sources, products applied to body parts other than the face are usually washed off after about 15 minutes. The end of the treatment is to apply moisturizing cream, which usually contains a sun protection factor (SPF) of 15. A typical course of treatment includes 6-10 peels over 4-6 weeks.</p> <p>When using at home, lotions, gels, lotions and creams are applied once or twice daily with fingertips or small cotton balls. Scrubs, that is, lotions or creams containing polished particles, rub the skin with a cloth or sponge, and then rinse off with water.</p> <p>Hair care products such as shampoo and conditioner will apply foam to the hair for a few minutes and then rinse off with water.

First, they're all anionic surfactants. Second, they are often used for personal care applications. But there are many differences. They have different molecular mechanisms. They have different functions and they have different raw materials.</p> <p>Sulfates<br /> Sulfate is a compound. It has carbon bonds and oxygen and sulfur bonds. They include substances such as sodium lauryl sulfate and sodium lauryl ether sulfate.</p> <p>At low pH, these substances plus the c-o-s bond hydrolyze to produce alcohol and inorganic sulfate. At a high pH, sulfate is stable in the base and, if ethoxylated to a relatively high level, produces a low-foaming alkali-soluble surfactant. Sulphates can be prepared by reaction of fatty alcohol or fatty alcohol ethoxylates with reagents such as SO3 or chlorosulfonic acid (CSA).</p> <p>The reason shampoo becomes thick foam in the shower is that it contains sulfate. Most shampoos and household cleansers contain sulfate, but it is not popular for frizzy hair (especially curly hair) to work and damage colored hair.</p> <p>Sulfonates<br /> Sulfonate is a compound that has a carbon-sulfur bond. The sulfonates contain cystos-olefin sulfonates (AOS). The bond is stable in a range that allows greater pH, so it can be used in an acidic environment. The reaction of pso 3 and pso 3 can produce pso - sodium olefin sulfonate.</p> <p>If you want to know more details of monoammonium glycyrrhizinate, please visit our website.</p> <p><a href="https://www.njchm.com/uploads/image/20180730/18/sles-70.jpg" rel="nofollow"><img src="https://www.njchm.com/uploads/image/20180730/18/sles-70.jpg" alt="sles-70.jpg" /></a></p> 2023-01-20T15:43:06+0900 http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/7EqaqAh4Nn1 njchm http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/7EqaqAh4Nn1#comments http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/7EqaqAh4Nn1 Difference Between Sodium Laureth Sulfate And Sodium Lauryl Sulfate(2023年01月20日) <p><a href="https://www.njchm.com/service/difference-between-sodium-laureth-sulfate-and-sodium-lauryl-sulfate.html">https://www.njchm.com/service/difference-between-sodium-laureth-sulfate-and-sodium-lauryl-sulfate.html</a></p> <p>Sodium dodecyl sulfate (SLS) and sodium laureth sulfate surfactant (SLES) are surfactants that play a role in foaming products. It is widely believed that the foam produced by a product is its performance.</p> <p>The composition of SLS and SLES reduces the surface tension of water. They can also be used as dispersants to properly mix spices and body spray. SLS and SLES can also be used in a variety of personal care products such as soap, shampoo, shower gel, toothpaste and other foaming products. SLS and SLES are also added to moisturizing lotions and sunscreens because of these properties.</p> <p>The difference between SLS and SLES is in the manufacturing process. SLS undergo a process called ethoxylation. And then you get SLES. Why do we have this ethoxylation process? Because SLS has some mild irritation on the skin, such as dry. The manufactured SLES are more gentle and do not irritate the skin.</p> <p>Many manufacturers do not use SLS because it is irritating. SLES should be softer on skin and hair, and manufacturers prefer to use SLES. If you have used SLS products and SLES products, you can feel the difference between them.</p> <p>Our store already has a large number of sodium lauryl sulfate, and the discount is very strong. As one of sodium lauryl sulfate manufacturers, we not only reduced the price, but also the most favorable price on the Internet. If you don't use SLES, try it now while the price is good! After using SLES, you will understand why so many of our customers are using SLES!

Its dissolution in water is due to its strong affinity for water.</p> <p>Compared with anionic surfactants, nonionic surfactant products have a higher emulsifying ability and a certain resistance to hard water. It is an indispensable ingredient in detergent and emulsifier formulations. Of course, compared with anionic surfactants, non-ionic surfactants also have the disadvantages of limited cloud point, poor alkali resistance, and high price.</p> <p>Non-ionic surfactants are mostly liquid and slurry, and their solubility in water decreases with increasing temperature. Non-ionic surfactants have various properties such as washing, dispersing, emulsifying, wetting, adding liquid, uniform dyeing, antiseptic, protective colloid and so on.

CAPB is a surfactant. It can be added to personal care products or used in bath products such as shampoo and soap for washing hands. It's also an organic compound. And you can see from its name that the main part of its molecule, the lauric acid group, comes from coconut oil. CAPB is a medium-strength surfactant that can also be used in cosmetics and has an emulsifying and thickening effect. It can also be used as an antistatic agent in hair toners that do not irritate the skin or mucous membranes. It is also added to personal hygiene products as a preservative.</p> <p>Lipophilic, lipophilic and hydrophilic properties are chemical properties of surfactants, so surfactants can remove dirt and oil from the skin.

So it's also a detergent</p> <p>Some surfactants are very irritant to the skin, but coconut oil aminopropyl betaine usually does not irritate the skin. So the coconut oil aminopropyl betaine is added to baby soap and shampoo. Because of the thickening and foaming properties of coconut oil aminopropyl betaine, it helps to moisturize the skin. It is generally used as a cleaner. However, some people are sensitive skin and may have an allergic reaction to the compound. So using cosmetics that contain coconut oil, amide propyl betaine, can cause red, itchy or peeling skin, It could be that surfactants can cause contact dermatitis.

But we prefer to touch the product and explore whether it really works. Alpha hydroxy acid is also known as AHA. It includes glycolic acid, lactic acid and citric acid. These products do not meet the needs.</p> <p>Now we analyze the most popular ingredient in the world - glycolic acid.</p> <p>Glycolic acid is a naturally occurring substance that is added to skin care products. It is good for the skin and restores skin elasticity and moisturization. The original state of glycolic acid is a powder composed of colorless crystals. It is tasteless. Let's first understand its benefits and its related products.</p> <p>The Benefits of Glycolic Acid<br /> Glycolic acid is very effective for skin treatment because of its high purity. The premise is safe and correct use. Many skin care products contain glycolic acid. Sensitive muscles can also be used.<br /> Glycolic acid is non-irritating and it can be used in skin care. Add more glycolic acid to the facial cleanser. In the first step of skin care, rejuvenate with glycolic acid.<br /> Some plants contain glycolic acids such as sugar cane, pineapple and beets. Its botanical properties treat skin diseases such as psoriasis, chloasma and seborrheic keratosis.<br /> Glycolic acid can exfoliate. It effectively removes dead cells from the outermost layer of the skin, making the skin brighter and fresher.<br /> Products containing glycolic acid also have effects on scars, skin discoloration and aging. If your skin is dull and aging, you can use exfoliating care or a household peel product that is infused with glycolic acid once a week.<br /> Glycolic acid has a moisturizing effect. It can replenish the lost moisture of the skin. Therefore, it can be used as an active ingredient of a humectant at a low concentration.<br /> Glycolic acid skin helps promote collagen production, which is very effective for plump skin. Collagen keeps skin tissue firm and resistant to wrinkles. You can see if you have glycolic acid when you purchase an anti-aging moisturizer or mask.

Its average particle size is 10-30 μm. Its average density is about 1100 kg / m 3 . It has a thermoplastic shell comprising a low boiling liquid hydrocarbon. When the thermoplastic shell is softened at elevated temperatures, the increased pressure of the hydrocarbon will cause the microspheres to expand 40 to 100 times. When the internal pressure of the microsphere, the shell tension and the external pressure reach equilibrium, the microspheres no longer expand. Expandable microspheres have become the world's lightest application because the density of expanded microspheres is less than 30 kg / m3 (0.03 g / cm3).</p> <p>Characteristics of Expandable Microsphere<br /> The first feature is cost savings.<br /> In thermoplastic materials such as PR, PP, PVC, PET, TPR, TPU, TPV, PA and paper/paperboard, expandable microspheres can be used as lightweight fillers and blowing agents. Expandable microspheres reduce product density, reduce volume, and reduce transportation costs. 30kg PVC or 25-30kg paper fiber can be replaced with 1kg expandable microspheres. Expandable microspheres can be used in many fields, including soles, wood-plastic composites, automotive parts, paper and cardboard, nonwovens, coatings, and the like.</p> <p>The second feature is low density.<br /> The heat density of the expandable microspheres is reduced. Add 3 Å of expanded microspheres to the material to reduce the material density by 10%. Or adding 1% unexpanded microspheres reduces the density by 10%. Product density is reduced but its volume and thickness do not increase. It helps to reduce the energy consumption of the car. It makes the sole lighter and more comfortable. It is widely used in the following products: soles, wood-plastic composites, auto parts, non-woven fabrics, ultra-light clay, etc.</p> <p>The third feature is surface modification.<br /> Microspheres of different particle sizes have different surface effects. The small particle size of 5 μm makes the surface smooth. Large particle size microspheres can produce relatively rough surfaces. 3D and a special cashmere surface make the surface smooth, soft and non-slip. It is widely used in the following materials: printing inks, leather coatings, paper and cardboard.</p> <p>The fourth feature is insulation.<br /> The microspheres have good insulation, sound insulation, electrical insulation and low water permeability because of their uniform closed cell structure. Because of this property, it can be used in the following products: wine stoppers, auto parts, crack fillers, silicon. Rubber, emulsion explosives, cables, etc.</p> <p>The fifth feature is flexibility.<br /> The expandable microspheres are elastic. It is a thermoplastic core-shell microsphere. It can be compressed under a certain pressure, or it can be restored to its original state. It can therefore be used in the following products: wine corks, automotive interiors, silicone rubber, leather coatings, cables and more.</p> <p>Want to know more details of DMC Catalyst, please visit our website.</p> <p><a href="https://www.njchm.com/uploads/image/20180730/18/flavors--fragrances_220x220.jpg" rel="nofollow"><img src="https://www.njchm.com/uploads/image/20180730/18/flavors--fragrances_220x220.jpg" alt="flavors--fragrances_220x220.jpg" /></a></p> 2022-10-28T16:47:37+0900 http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/pLWrgiKxu1u njchm http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/pLWrgiKxu1u#comments http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/pLWrgiKxu1u Use of Polyether Polyol(2022年10月28日) <p><a href="https://www.njchm.com/use-of-polyether-polyol.html">https://www.njchm.com/use-of-polyether-polyol.html</a></p> <p>Polyether polyol is abbreviated as polyether. It is an oligomer whose main chain contains ether bond (—R—O—R—) and the terminal group or side group contains more than 2 hydroxyl groups (—OH). It is prepared by addition polymerization of an initiator (a compound containing an active hydrogen group) with ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO), etc. in the presence of a catalyst. The largest polyether producers are all common polyether polyols. Polyether polyols are produced with glycerol (glycerol) as the initiator and epoxide, by changing the PO and EO addition methods (mixed addition or separate addition), addition ratio, addition order and other conditions.</p> <p>The main purpose<br /> 1. Detergent or defoamer<br /> L61, L64, F68 are used to prepare low-foam, high detergency synthetic detergent;<br /> L61 and L81 are used as defoamers in the papermaking or fermentation industry;<br /> F68 is used as an antifoaming agent in the blood circulation of artificial heart-lung machine to prevent air from entering.</p> <p>2. Excipients and emulsifiers<br /> Polyether has very low toxicity and is often used as a pharmaceutical excipient and emulsifier; it is often used in the oral cavity, nasal sprays, eyes, ear drops and shampoos.</p> <p>3. Wetting agent<br /> Polyether is an effective wetting agent and can be used in acid baths for fabric dyeing, photographic development and electroplating. F68 is used in sugar factories. Due to the increased water permeability, more sugar can be obtained.</p> <p>4. Antistatic agent<br /> Polyether is a useful antistatic agent, and L44 can provide long-lasting static protection for synthetic fibers.</p> <p>5. Dispersant<br /> Polyether is used as a dispersant in emulsion paints. F68 acts as an emulsifier during the emulsion polymerization of vinyl acetate. L62 and L64 can be used as pesticide emulsifier, as coolant and lubricant in metal cutting and grinding, and as lubricant during rubber vulcanization.</p> <p>Want to know more details of polyether polyol uses and glycolic acid, please visit our website.<br /> <a href="https://www.njchm.com/uploads/image/20180730/18/pesticide-intermediate_220x220.jpg" rel="nofollow"><img src="https://www.njchm.com/uploads/image/20180730/18/pesticide-intermediate_220x220.jpg" alt="pesticide-intermediate_220x220.jpg" /></a></p> 2022-10-28T16:47:04+0900 http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/BbaGPz7mSlm njchm http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/BbaGPz7mSlm#comments http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/BbaGPz7mSlm Application Of Sodium Lauryl Ether Sulfate In Shampoo(2022年10月28日) <p><a href="https://www.njchm.com/solution/application-of-sodium-lauryl-ether-sulfate-in-shampoo.html">https://www.njchm.com/solution/application-of-sodium-lauryl-ether-sulfate-in-shampoo.html</a></p> <p>Application Of Sodium Lauryl Ether Sulfate In Shampoo</p> <p>The main surfactant used in shampoos is to impart a shampoo cleansing action through the washing process. There are many types of such surfactants, but mainly anionic surfactants. Nowadays, the amount of ammonium laureth sulfate (AESA) and (K12A) is also very large. The ammonium salt has a high foaming rate and is less irritating than the sodium salt. Some large brands use ammonium salt as the main surfactant. Sodium laureth ether sulfate can be used in products for skin and sodium sulphate can be used in soap making.</p> <p>Currently, the most commonly used shampoo main surfactants are lauryl ether sulfates (abbreviated as AES or SLES) and lauryl sulfates (AS or SLS), sometimes a mixture of the two. China generally uses sodium laureth polyoxyethylene ether sulfate and ammonium laureth polyoxyethylene ether sulfate, but mainly sodium salt.</p> <p>The advantages of sodium salt<br /> 1. The sodium salt is less dependent on the pH of the system.<br /> 2. Sodium salt synthesis is easier and more economical.<br /> 3. The detergency and foaming power of the sodium salt is slightly stronger than that of the ammonium salt, and the formulation amount may be slightly lower.</p> <p>Therefore, sodium lauryl ether sulfate is a very good surfactant choice in the shampoo making process.</p> <p>Want to know more details of Allyl Glycidyl Ether, please visit our website.</p> <p><a href="https://www.njchm.com/uploads/image/20200714/16/adhesives_220x220.jpg" rel="nofollow"><img src="https://www.njchm.com/uploads/image/20200714/16/adhesives_220x220.jpg" alt="adhesives_220x220.jpg" /></a></p> 2022-10-28T16:46:05+0900 http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/1Ql7uD0QsCN njchm http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/1Ql7uD0QsCN#comments http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/1Ql7uD0QsCN Alpha Olefin Sulfonate Application(2022年10月28日) <p><a href="https://www.njchm.com/solution/alpha-olefin-sulfonate-application.html">https://www.njchm.com/solution/alpha-olefin-sulfonate-application.html</a></p> <p>Sodium Alpha Olefin Sulfonate Application of washing powder<br /> The decontamination test showed that LAS and AOS showed good synergy in both phosphorous powder and phosphorus-free powder. Among the phosphorous detergent, LAS: AOS has the most significant synergy at 8:2. In the non-phosphorous washing powder with LAS and AOS as anionic active ingredients, the decontamination of AOS increased significantly when the proportion of anionic active components was greater than 20 %. The decontamination synergy of AOS in phosphorus-free washing powder is more prominent than that in phosphorous powder.</p> <p>AOS and enzymes have better solubility. The activity of residual enzymes in detergent solutions containing domestic proteinases and imported proteinases(such as Savnase) was compared. Over time, the residual enzyme activity of anionic active groups divided into pure LAS was low. The residual enzyme activity is higher in detergent solution with AOS partial replacement or all substitution of LAS.</p> <p>There is little difference between AOS and LAS decontamination at higher temperatures and prolonged washing(eg, 60 °C or more, 1 hour washing). However, when washing at room temperature(10-40 °C, washing 10-29 minutes), AOS has higher decontamination power than LAS. Compared with LAS, AOS has a strong hard water resistance, so it also shows AOS advantages in areas with higher hard water.</p> <p>LAS is superior to oil/granular decontamination, while non-ions such as fatty alcohol ether are most suitable for washing dirt and dirt on the skin. The combination of the two can achieve good decontamination effects, and AOS has good decontamination effects on sebum and oily and powdery dirt.</p> <p>The amount of ash deposition on the fabric after washing the fabric with apatite washing powder containing 4 A zeolite, soda and soda. The phosphorous washing powder that replaces LAS with AOS part is smaller than the phosphorous washing powder that uses LAS alone. After washing, the gray deposition of the fabric is small, not easy to knot, and yellowing. (reference formula)</p> <p>Alpha Olefin Sulfonate Application of Soap<br /> Soap produces insoluble saponin in hard water, affecting the decontamination effect. Adding AOS can increase the solubility of soap in water, and the wettability and foam power of soap liquid at low temperatures also increase rapidly. AOS is added to soaps with sodium adipose as the main ingredient. The various characteristics of soaps are improved, foaming force is enhanced, hard water resistance is improved, flexibility is enhanced, and cracking is not easy.</p> <p>Liquid Detergents Application<br /> Due to the large irritation of LAS, many washing products no longer use LAS as an active component, while AOS has low irritation and good biodegradability, making it a more suitable alternative. In liquid detergents, AOS has a greater influence on the viscosity of the product. The viscosity is improved with the commonly used fatty alcohol diethanolamide and Na-Cl. The effect is not ideal. The use of fatty alcohol monoethanolamide, amine oxide, betaine and NH4Cl can play a good adhesion role. Due to the characteristics of AOS in decontamination, hard water resistance, viscosity, etc., AOS has a wide range of applications in liquid detergents with high active components.</p> <p>Alpha Olefin Sulfonate Application of personal care supplies<br /> AOS is as mild as AES, and LAS and AS are much larger than AOS. Therefore, AOS has a wide range of uses in personal care products. AOS is extremely stable under acidic conditions. Normal human skin is weakly acidic(pH is about 5.5) and is suitable for using AOS as a component of personal cleaning products. The shampoo with AOS as the main active component is better than that with K12. Renso reported that the foam released by AOS was full of cream and felt like soap when washed. This characteristic is suitable for the washing habits of Chinese people. Therefore, AOS can be used in personal care products such as bath fluids, hand sanitizer and cleansing milk. Reference formula.</p> <p>Other Alpha Olefin Sulfonate Application<br /> AOS has a wide range of applications in the textile printing and dyeing industry, petroleum chemicals, and three oil extraction and industrial cleaning. AOS can be used as a concrete density modifier, foaming wall board, and fire fighting foam. It can also be used as a pesticide emulsifier, wetting agent, etc..</p> <p>Want to know more details of Allyl Glycidyl Ether, please visit our website.</p> <p><a href="https://www.njchm.com/uploads/image/20180730/18/polyurethane-coatings_220x220.jpg" rel="nofollow"><img src="https://www.njchm.com/uploads/image/20180730/18/polyurethane-coatings_220x220.jpg" alt="polyurethane-coatings_220x220.jpg" /></a></p> 2022-10-28T16:45:37+0900 http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/3dJoAqK82uZ njchm http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/3dJoAqK82uZ#comments http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/3dJoAqK82uZ Preparation of Ethyl Iodide(2022年10月28日) <p><a href="https://www.njchm.com/preparation-of-ethyl-iodide.html">https://www.njchm.com/preparation-of-ethyl-iodide.html</a></p> <p>Principle:<br /> Ethyl iodide synthesis is usually reacted with ethanol, iodine and red phosphorus, but the reaction is slow, and it needs to be heated in a reflux device for several hours.</p> <p>Supplies:<br /> Flask, straight condenser, beaker, red phosphorus, alcohol, iodine crystals, zeolite, 5% NaOH solution, anhydrous calcium chloride.</p> <p>Operation:<br /> 2 g of red phosphorus and 25 ml of alcohol were added to a 125 ml flask, and 18 g of finely divided iodine crystals were added in portions under shaking, followed by the addition of 3 zeolites. A straight condenser was placed on the flask and allowed to reflux for half an hour by heating in a water bath. After the reaction is completed, the mixture is cooled, and the reflux straight condenser is discharged, and then the condenser is replaced with a common distillation apparatus. It should be noted that the receiver should be filled in a cold water bath to prevent the produced iodoethane from being volatilized.</p> <p>The iodoethane was distilled off in a boiling water bath. The distillate can be transferred to a separatory funnel and browned as the liquid contains iodine. First wash the mixed ethanol with distilled water, then wash the free iodine with a small amount of 5% NaOH solution, and dry it with anhydrous calcium chloride in a condenser, then put it on a water bath for distillation, then there is iodine. When ethane is present, a fraction of 70 - 74 ℃ (343-347 K) can be collected. Pure ethyl iodide is a colorless oily liquid with a boiling point of 72.3 °C.</p> <p>Remarks:<br /> 1. When preparing ethyl iodide, add iodine once. However, the added iodine should not be excessive, and the reaction will be exothermic, which will increase the temperature. Therefore, keep the reactants at 20 ℃ to prevent a large amount of volatile substances from being distilled out to cause loss. Iodoethane should be stored in a brown closed bottle to prevent problems with lightening and loss of volatilization.</p> <p>2. The outlet tube of the distiller should be inserted under the water surface, and always pay attention to prevent back suction.</p> <p>3.The experiment is not well controlled, and the purity of iodoethane will have an effect.

Licorice is sweet, so it is also known as sweet grass and honey grass. There are four main chemical components: triterpenoids, flavonoids, alkaloids and polysaccharides. Among them, the triterpenoids include glycyrrhizic acid and hydroxyglycyrrhetinic acid.</p> <p>Glycyrrhizic acid is also known as glycyrrhizin. It is white crystal, crystallized with glacial acetic acid, and has a strong sweet taste. The molecular formula is C42H62O16 and the molecular weight is 822.90. The pure product is a white, odorless crystalline powder. Its melting point is 212 ℃ ~ 217 ℃, soluble in hot water and hot dilute ethanol, almost insoluble in anhydrous ethanol or ether. Glycyrrhizic acid is often present in plants in the form of calcium, potassium, ammonium salts, and the like. The ammonium salt extracted from the licorice extract prepared from the licorice root is 50 to 100 times sweeter than sucrose. The refined sodium glycyrrhizate and potassium salt have a sweetness of 200 to 300 times that of sucrose, and are a natural sweetener.</p> <p>After the entrance of glycyrrhizin, you can't feel the sweetness immediately, but gradually feel it, and it will last for a long time and still have the aftertaste. Therefore, glycyrrhizin is compounded with sugars such as granulated sugar and glucose to obtain a sweet taste with good taste. Because it is a non-sugar, high-sweet sweetener, it has no disadvantages such as browning, moisture absorption and fermentation. Glycyrrhizin can also be used as a therapeutic agent for anti-gastrointestinal ulcers, an antidote, an anti-inflammatory agent, and a blood lipid lowering, anti-atherosclerosis, and cholesterol lowering in medicine. At present, glycyrrhizin has been widely used in food, medicine, cosmetics, beverages, cigarettes and other industries.</p> <p>China's licorice resources are abundant, with licorice containing 7% to 10% of licorice and about 5.5% to 9.0% of licorice. Licorice extract can be obtained by solvent leaching to obtain licorice extract, and further processing can produce glycyrrhizic acid.</p> <p>Monoammonium glycyrrhizinate is a white crystalline powder with a special sweet taste. It has antibacterial, anti-inflammatory, anti-viral, anti-microbial, liver and liver protection, throat cleansing, anti-oxidation, inhibition of melanin, high sweetness, low heat energy and health care.

Compared with similar polyols made using basic(e.g., KOH)catalysts, polyether polyols made from the catalyst have low unsaturations, narrow molecular weight distributions, have high molecular weight, and are useful in making a variety of polyurethane products. DMC catalyst is highly active in epoxide polymerization reactions used to prepare polyether polyols.</p> <p>We can yield the DMC more than 20000 kg within one year, and thus afford to produce 50~70 ten thousand tons of polyols. This catalyst is white or light yellow powder, is suitable for preparation of polyols with 1~6 functions. Compared with basic catalysts, this catalyst can be used with less amount (30ppm), and reaction time of polymerization is reduced largely, and the polyols products are not necessary to be refined. The DMC is suitable for using in common epoxide polymerization reactors, but it can be better if reactors have both of stirring and cycling systems.</p> <p>When using the DMC production period is short, thus the costs for production are reduced while the property of products are advanced.</p> <p>Conditions wanted for initiators<br /> 1. polyethers with 1~3 0r more hydroxyl groups<br /> 2. molecular weight:for at least 2 hydroxyl groups---350~1000; for monols---with boiling point more than l00℃<br /> 3. ∑Mn+ (mainly for K、Naions)≤5ppm<br /> 4. water content≤0.1%<br /> 5. acid value≤0.15mgKOH/g</p> <p>Applying procedure<br /> 1. Weigh certain amount of initiator and the catalyst. The catalyst's amount is generally 30ppm relative to the product (it mainly refers to N220 with 2 hydroxyl groups and N330 with 3 hydroxyl groups). The amount of the catalyst can reduce if the molecular weight of products are relatively high, e.g. for N240, the amount can be 20~25ppm.<br /> 2. The mixture is stirred and is stripped under a vacuum with pressure less than l0 mm (Hg), and is heated to 130~145℃ to remove traces of water from the starter. Generally it needs more than 40min after the temperature rises to 130~145℃.<br /> 3. Propylene oxide (PO) or mixture of ethylene oxide (EO) and PO is fed to the reactor, under a pressure of 0.1—0.25Mpa. Additional PO or PO and EO is not added until an accelerated pressure drop occurs in the reactor (temperature can reach above 180℃,but this can not harm the activity of DMC or the properties of products). PO or PO and EO is added while maintaining a reactor pressure generally less than 0.1Mpa,temperature 140±10℃.<br /> 4. After PO or PO and EO addition is complete, the mixture is held at 140±5℃ until a constant pressure is observed. Residual unreacted monomer (generally only traces) is then stripped.<br /> <a href="https://www.njchm.com/uploads/image/20180730/18/surfactant_220x220.jpg" rel="nofollow"><img src="https://www.njchm.com/uploads/image/20180730/18/surfactant_220x220.jpg" alt="surfactant_220x220.jpg" /></a></p> 2022-10-28T16:44:08+0900 http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/CnzwNY7Vay2 njchm http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/CnzwNY7Vay2#comments http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/CnzwNY7Vay2 Ethyl Iodide(2021年11月24日) <p><a href="https://www.njchm.com/products/ethyl-iodide-cas-75-03-6.html">https://www.njchm.com/products/ethyl-iodide-cas-75-03-6.html</a></p> <p>Glycolic acid is an organic chemical.

It has the chemical formula C2H5I and is prepared by heating ethanol with iodine and phosphorus. On contact with air, especially on the effect of light, it decomposes and turns yellow or reddish from dissolved iodine.

It is generally used in the preparation of flavoring for food, tobacco and daily use. It can also used in barbecue food, drinks, candy, etc.</p> <p>Cationic surfactants are mainly nitrogen-containing organic amine derivatives. Since the nitrogen atoms in their molecules contain lone pair electrons, they can bind hydrogen with hydrogen molecules in the acid molecule and bring the amino group to positive charge. Therefore, they have good surface activity in acidic media; they easily precipitate in alkaline media and lose surface activity. In addition to nitrogen-containing cationic surfactants, there are also a small number of cationic surfactants containing elements such as sulfur, phosphorus, and arsenic.</p> <p>Cationic surfactants have a long history of industrial use, and demand has been increasing rapidly year by year, but due to its special use as fungicides, fiber softeners and antistatic agents, it has a small demand compared to anionic and non-ionic surfactants. The development and use of cationic surfactants in China started very late, but its development rate is faster. However, due to the narrow range of application of cationic surfactant suppliers and the small amount of use, the output is very small. Until 2002, the annual output was still only a few thousand tons, which was less than 1% of the total output of various surfactants.</p> <p>Cationic surfactants generally have good emulsifying, wetting, washing, sterilizing, softening, antistatic and anti-corrosive properties. Due to their special properties and applications, they have a good development potential both in industrial and civil applications.</p> <p>Cationic surfactants have good bactericidal, softening, anti-static, anti-corrosive, and certain emulsifying and wetting properties, and are often used as phase transfer catalysts. However, such surfactants are rarely used as detergents alone because many substrates are usually negative in aqueous solutions, especially alkaline aqueous solutions. In addition, the main application areas of these surfactants are not like other surfactants, which are used to reduce the surface tension, its structural characteristics make them used for other special aspects. Based on the chemical structure of cationic surfactants, they can be divided into four types: amine salt type, quaternary ammonium salt type, heterocyclic type, and barium salt type.<br /> <a href="https://www.njchm.com/uploads/image/20180730/18/pharmaceutical-intermediate_220x220.jpg" rel="nofollow"><img src="https://www.njchm.com/uploads/image/20180730/18/pharmaceutical-intermediate_220x220.jpg" alt="pharmaceutical-intermediate_220x220.jpg" /></a></p> 2021-11-18T13:00:16+0900 http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/A4kbMUgL7jY njchm http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/A4kbMUgL7jY#comments http://pastport.jp/user/njchm/timeline/Nanjing%20Chemical%20Material%20Corp./event/A4kbMUgL7jY Calcium Propionate(2021年11月19日) <p><a href="https://www.njchm.com/products/calcium-propionate-cas-4075-81-4.html">https://www.njchm.com/products/calcium-propionate-cas-4075-81-4.html</a></p> <p>Glycolic acid is an organic chemical.

In the presence of alkali catalyst, active hydrogen compounds initiate ring opening and oxide addition will continue until the required molecular weight is obtained. The number of hydroxyl groups in polyether polyol is determined by the number of unstable hydrogen atoms in the initiator. If the initiator has two active hydrogen, glycol will be formed. The reactivity of polyether polyol to isocyanates depends on the initiator and the type of epoxy monomer that ends the ring-opening polymerization. The primary hydroxyl produced by polyol capped with ethylene oxide is more reactive than the secondary hydroxyl produced by propylene oxide, which is ideal for applications requiring rapid curing time. However, the use of initiator based on ethylene oxide and amine can also make the coating more hydrophilic and damage the barrier performance of the coating (such as waterproof membrane), so a good balance between reactivity and hydrophobicity is necessary.</p> <p>The VOC limitation faced by epoxy coatings increases the use of epoxidized diols and Polyol (also known as reactive diluents) to reduce the use of solvents in epoxy formulations. However, due to the low reactivity or the epoxy ring near the aliphatic chain, the curing time of epoxy coating containing a large amount of reactive diluents can be greatly prolonged. Moreover, reactive diluents increase the cost of epoxy coating formulation. Therefore, due to their low viscosity and high reactivity, polyether polyol makes polyurethane coatings become the substitute of 100% solid epoxy system used in the application of anticorrosive coatings.</p> <p>Nanjing Chemical Material Corporation.

Reducing the surface tension will reduce the energy required to distribute the droplets onto the film, thereby weakening the cohesion of the liquid and enhancing its adhesion. An example of how wetting agents work is the formation of micelles. The micelle consists of a hydrophilic head, which forms an outer layer around the lipophilic tail. When it is in water, the tail of the micelle can surround the oil drop and draw its head into the water.</p> <p>Dishwashing soap is a good example of a wetting agent. For all food oils and the cohesion on the board, it is difficult for water to disperse and clean the board. Soap dissolves all these unwanted particles, showing us a clean surface. Soap can also reduce the surface tension of water and make it evenly distributed on the whole surface.</p> <p>There are four types of wetting agents: anionic wetting agent, cationic wetting agent, amphoteric and non-ionic wetting agent.</p> <p>1. When mixed with water, anionic, cationic and amphoteric wetting agents will ionize.</p> <p>2. Anionic wetting agent has negative charge, while cationic wetting agent has positive charge.</p> <p>3. According to the acidity of the solution, amphoteric wetting agents can act as anions or cations.</p> <p>4. Nonionic wetting agents will not ionize in water. The possible advantage of using a non-ionic wetting agent is that it does not react with other ions in the water, which may lead to the formation of precipitates.</p> <p>How to identify if a liquid contains a wetting agent</p> <p>One way to identify if a liquid contains a wetting agent is to spread the liquid over a greased surface. If the liquid does not contain a wetting agent, its cohesion will overwhelm the adhesion, resulting in the formation of droplets on the surface. If the liquid does contain a wetting agent, the grease will be dissolved and the surface tension of the liquid will be reduced, resulting in the adhesion force exceeding the cohesion force, which will cause the liquid to spread evenly along the surface.</p> <p>Nanjing Chemical Material Corporation.
