Carboxymethyl Cellulose
China [CN] Carboxymethyl Cellulose (CMC)
Characters:
The Carboxymethyl Cellulose (CMC) is produced by chemical modification of cellulose, the most abundant polymer in nature and a major component of wood and cotton.CMC acts as thickener, rheology modifier, water retention aid, binder, dispersant, floating aid, etc. This wide range of properties makes CMC virtually useful everywhere water is involved in a process and more typically in ceramics, coatings, detergency, drilling fluids, food, mining, paper, textiles (sizing and printing).
In the pharmaceutical industry, as drug slurry thickener and stabilizer can be used as an ointment drugs aquasorb and dispersing agent, also as a tablet disintegrating agents, Controlled release efficacy, injectable emulsion mix oil.Technical indicators:
