Carboxymethyl StarchS

Carboxymethyl starch (CMS) is an important modified starch with unique properties due to the presence of negatively charged functional group (CH2COO-). Carboxy Methyl starch has a wide range of applications in industries, mostly used for purposes of thickening, stabilization, water preserving. It is also used in textile industry as thickening agent in textile printing paste and as sizing agent especially for hydrophilic yarn. In soaps a small addition of Carboxymethyl starch increases the suspending power and overall washing efficiency of a soap, but the same amount of Carboxymethyl starch very greatly improved the suspension action and overall efficiency when a sodium salt of surface active agents in the detergents. Carboxymethyl starch being used in the corrugated box gum along with plain tapioca starch. Addition of Carboxymethyl starch will improve the mixture of corrugation paste by keeping tapioca starch in suspension during corrugation. CMS can be used for sizing mixture preparation for yarn sizing application.
