Carboxy Methyl Cellulose(CMC)
CAS: 9004-32-4
Carboxy Methyl Cellulose(CMC) is also named as Sodium Carboxy Methyl Cellulose, is anionic water-soluble polymer derived from purified cotton linter or wood pulp, adopting the procedure of alkalized and etherized, washing, recycling, drying and fracturing. As a thickener, stabilizer and water retaining agent, CMC is easy soluble in both cold and hot water. It provides good properties of thickening, water retention, film-forming, rheology and lubricity, CMC can be widely used in food, personal care products, industrial paints, ceramics, oil drilling, building materials etc.
