Sodium CMC For Detergent Industry

SCMC is used in detergents as an Anti soil redeposition agent, particle suspender, skin protector, color retention agent, stabilizer, homoginiser, texture protector.

A very special property of SCMC is to stop the redeposition of dirt particles on to the cloth in laundering process. Addition of a small amount of SCMC to detergents especially a synthetic detergent results in a marked improvement of its soil suspending properties. Synthetic detergents as a class are comparatively poor in this respect and the practice of adding SCMC to them is universal. SCMC is most beneficial in the laundering of cotton. About 10% of the "active matter" of a laundry detergent powder should be the percentage added as SCMC. This is normally 1-2% SCMC. It is the carboxyl group, which attracts the dirt and holds it, stopping redeposition onto the cloth.
