Product Details

Sodium carboxymethyl starch (CMS) is the best substitute for sodium carboxymethyl cellulose (CMC).
CMS is a representative product of modified starch. It is listed by the Ministry of Chemical Industry as one of the six products developed in the "Ninth Five-Year Plan" and an indispensable raw material in the ten pillar industries.
CMS has the functions of stability, thickening, emulsifying dispersion, adhesion, suspension, water retention, chelating, flocculation, shape, leveling and ion exchange.
CMS is widely used in food, medicine, cosmetics, toothpaste, textile, printing and dyeing, paint, paper, detergent, environmental protection, building materials, batteries, welding electrodes and oil drilling, geological drilling, mining and development, natural gas mining and other fields.
In addition to the function of CMC, CMS also has the advantages of fast dissolution, large expansion ratio, energy saving, easy operation and low comprehensive cost, and has good promotion and use value.

CMS is an ionic starch ether, which is an important representative of starch derivatives.
Appearance: White or yellowish free flowing powder.
Physical properties: non-toxic, odorless, tasteless, soluble in cold water, insoluble in ethanol, solid and aqueous solution is weak alkaline, with good stability.
