Carboxymethylcellulose sodium (CMC) is a water-soluble, anionic cellulose ether derived from natural cellulose. It is widely used as a thickener, stabilizer, and emulsifier in food, pharmaceuticals, cosmetics, and construction materials for its ability to enhance viscosity, improve texture, and bind components. CMC has a CAS number of 9004-32-4 and is stored at ambient conditions with no signal word warnings. It is non-toxic and generally recognized as safe for food applications when used within regulatory limits. Molekula supplies Carboxymethylcellulose Sodium from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
