Sodium
Carboxymethyl Cellulose (CMC)
Formula: C6H7O2(OH)2OCH2COONa,CAS no.: 9004-32-4,HS code): 3912.
3100, CMC is a kind of white grain and fibrous powder which are
nontoxic and easy to absorb water. It has good water solubility,
stickiness, emulsification, enzyme resistance and thermal stability.
The transparency of its solution gets corresponding improvement with
the increase of substitution degree. The water solubility of CMC
presents neutral or light alkalescence. It will precipitate when
meeting the metallic ion with more than bivalence.
Application: Sodium Carboxymethyl Cellulose (CMC) is widely used to
Architecture industry, ceramics industry, Oil industry, Paper-making
industry and detergent,, textile, electric welding industry.
