Application

Sodium carboxymethyl cellulose (CMC) is a versatile, biodegradable, and non-toxic water-soluble polymer widely recognized for its expansive industrial applications. As a modified cellulose derivative, CMC is renowned for its utility in various fields, functioning as a soil-suspending agent in detergents, a stabilizing agent in food products like ice cream, and an adhesive in the pharmaceutical industry. Its water solubility and insolubility in organic solvents make it ideal for usage in industries such as electronics, pesticides, leather, plastics, printing, and ceramics. Often referred to as "industrial monosodium glutamate," CMC serves as an adhesive, flocculating agent, chelating agent, emulsifier, thickener, water-retaining agent, and film-forming material. Its broad application prospects and stable performance underscore its significance as one of the most essential products in the cellulose ether family.
