Detergent grade CMC Sodium carboxymethyl cellulose is to prevent dirt redeposition, its principle is the negative dirt and adsorbed on the fabric itself and charged CMC molecules have mutual electrostatic repulsion, in addition, CMC can also make the washing slurry or soap liquid effective thickening and make the composition of the structure stability.
Detergent grade CMC is the best active agent for synthetic detergent, and mainly plays an anti-fouling redeposition role. One is to prevent the deposition of heavy metals and inorganic salts; The other is to make the dirt suspended in the water solution because of washing, and disperse in the water solution to prevent the dirt deposition to the fabric.
