KimaCell® CMC FD40 sodium carboxymethyl cellulose is also called as CMC or SCMC. Usually short cotton thread (cellulose content up to 98%) or wood pulp is used as raw material, treated with sodium hydroxide and then reacted with sodium chloroacetate. According to different reaction conditions, a wide range of substitution degrees of carboxymethyl groups can be obtained (ie 0.4~1.5, the highest theoretical value is 3.0) CMC. The degree of substitution of CMC directly affects the solubility, emulsification, thickening, stability, acid resistance and salt resistance of CMC.

Application of CMC FD40

KimaCell® CMC FD40 sodium carboxymethyl cellulose is Anti-redeposition agents are detergent additives used to keep clothes from redepositing or returning to the laundry during the wash. Anti-redeposition agents are water-soluble and generally negatively charged. Carboxymethylcellulose is a polymer derived from natural cellulose. Unlike cellulose, CMC is highly water soluble. CMC is used in very low levels (0.5-1%) in some of our laundry detergents. It is a dispersing polymer that helps disperse soil in the wash water, thus preventing redeposition of soil on washed fabrics. Polyvinylpyrrolidone is more effective on wool and synthetic fabrics. Polyethylene glycol (PEG) and polyvinyl alcohol can also be used as anti-redeposition agents.
