Aqualon sodium carboxymethylcellulose
Aqualon sodium carboxymethylcellulose (CMC) is made by reacting sodium monochloroacetate with alkalicellulose under rigidly controlled conditions. The resultant anionic polymer is purified and dried. Purified CMC for personal care and cosmetic applications is typically sold at 99.5 percent minimum purity. In addition to thickening aqueous systems, CMC is used in personal care products for water binding, syneresis control and its ability to suspend pigments and active ingredients in solution. Aqualon CMC is an anionic, water-soluble polymer.
A variety of CMC grades are available, with varying degrees of substitution, viscosities and particle sizes. S-types provide smooth solutions, based on uniform substitution. O-types provide solubility and viscosity stability on storage in low pH media. Aqualon CMC grades designated P or PH are compliant with the monograph requirements of the National Formulary.
