Sodium Carboxymethyl Cellulose Uses in Detergent

Preventing Re-deposition of Dirt Effect
Adding sodium carboxymethyl cellulose in detergent has the function of preventing the re-deposition of dirt. The working principle is that negatively charged dirt granule and charged sodium carboxymethyl cellulose molecular absorbing on fabrics has mutual electrostatic repulsion.

Thickening Effect of CMC Detergent Grade
Sodium carboxymethyl cellulose can effectively thicken washing slurry or soap lye, and stabilize the structure of compositions. With dosage of 0.5%-2.0% can get satisfactory performance.

Application of Detergent Grade CMC
CMC detergent grade has good thickening, dispersing and emulsifying effects after dissolving into water. It can absorb the oil around the oil particles, wrap the oil, make the oil suspended and dispersed in water, and form a hydrophilic membrane on the surface of the washed articles, so as to prevent the oil from contacting the washed articles directly.
CMC in detergent powder has a high degree of substitution, uniformity and good transparency. The dispersion in water is good, and the resistance to reabsorption is good. Super high viscosity, good stability, excellent thickening and emulsification.
