Specification of CMC FD7

Application of CMC FD7

KimaCell® CMC FD7 sodium carboxymethyl cellulose is widely used in detergents to prevent redeposition of dirt, the principle is that there is mutual electrostatic repulsion between the negatively charged dirt and the charged CMC molecules adsorbed on the fabric. In addition, CMC can also make the washed slurry or The soap effectively thickens and stabilizes the structure of the composition. The wetting of the detergent solution to the washed substrate and dirt and the penetration between the two interfaces; The surfactant in the cleaning agent emulsifies, solubilizes and disperses the oily dirt, separates the dirt from the solid surface, and disperses or emulsifies it in the washing medium (usually water); Prevent emulsified oily dirt and dispersed solid dirt from redepositing on the substrate surface. The washing process is a reversible process, and the dirt dispersed and suspended in the medium may also be redeposited on the solid surface. This process is called dirt redeposition.
