Sodium Carboxymethyl Cellulose(CMC)

Sodium Carboxymethyl Cellulose Supplier

Sodium carboxymethyl cellulose, also known as carboxymethyl cellulose, cellulose gum, CMC is the most widely used and most used cellulose type in the world today. White fibrous or granular powder. Sodium CMC is a cellulose derivative with a glucose polymerization degree of 100 to 2000. CMC is odorless, tasteless, tasteless, hygroscopic, and insoluble in organic solvents.

Sodium carboxymethyl cellulose is compatible with strong acid solutions, soluble iron salts, and some other metals such as aluminum, mercury and zinc.Sodium carboxymethyl cellulose can form co-aggregates with gelatin and pectin, and can also form complexes with collagen, which can precipitate certain positively charged proteins.CAS: 9004-32-4

3.Application

CMC has the functions of adhesion, thickening, strengthening, emulsification, water retention and suspension.

CMC is used as a thickener in the food industry, has excellent freezing and melting stability, and can improve the flavor of the product and extend the storage time.
CMC can be used as an emulsion stabilizer for injections, a binder and film-forming agent for tablets in the pharmaceutical industry.
CMC in detergents, CMC can be used as an anti-soil redeposition agent, especially the anti-soil redeposition effect on hydrophobic synthetic fiber fabrics, which is significantly better than carboxymethyl fiber.
CMC can be used to protect oil wells as a mud stabilizer and water-retaining agent in oil drilling. The consumption of each oil well is 2.3t for shallow wells and 5.6t for deep wells.
CMC can be used as an anti-settling agent, emulsifier, dispersant, leveling agent, and adhesive for coatings. It can evenly distribute the solids of the coating in the solvent so that the coating will not delaminate for a long time. It is also widely used In the paint.
