What is Carboxymethyl Cellulose CAS 9000-11-7 Manufacturer & Supplier China?
Carboxymethyl Cellulose (Acid Form, CAS 9000-11-7) is an anionic cellulose ether produced by carboxymethylation of natural cellulose. The acid form of CMC appears as a white to off-white powder and is practically insoluble in water, but it can swell or dissolve under alkaline conditions to form CMC salts. It is widely used as a key raw material for the production of sodium CMC and other derivatives, and serves in papermaking, ceramics, textile sizing, and biodegradable material modification. The product is non-toxic, chemically stable, and suitable for a variety of industrial processes.
