PRODUCT OVERVIEW

Product Description

CMC Series Sodium Carboxy Methyl Cellulose is a pale white to yellowish powder that is soluble in water and available in different grades for a wide range of industrial applications. CMC grades can vary according to the intended industry, raw-material source, purity, degree of substitution, and viscosity. These characteristics influence water solubility and product performance. In detergent systems, CMC functions primarily as a suspending and anti-redeposition agent, helping keep removed dirt particles dispersed in the washing solution and reducing their redeposition onto fabrics.
