Sodium carboxymethyl cellulose CAS#9004-32-4
Sodium carboxymethyl cellulose(9004-32-4) is a water-soluble polymer. As a solution in water, it has thixotropic properties. It is useful in helping to hold the components of pyrotechnic compositions in aqucous suspension (e.g., in the making of black match). It is also an especially effective binder that can be used in small amounts in compositions, where the binder can intcrfere with the intended effect (e.g., in strobe compositions). However, its sodium content obviously precludes its use in most color compositions. Sodium carboxymethyl-cellulose is manufactured from cellulose by various proccsses that replacc some of the hy drogen atoms in the hydroxyl[OH] groups of the cellulose molecule with acidic carboxymethyl [-CH2CO.OH] groups,which are neutralized to form the corresponding sodium salt. Sodium carboxymethyl cellulose is white when pure; industrial grade material may be grayish-white or cream granules or powder.

Product Application of Sodium carboxymethyl cellulose CAS#9004-32-4
Carboxymethylcellulose sodium salt is used in drilling muds, in detergents as a soil-suspending agent, in resin emulsion paints, adhesives, printing inks, textile sizes and protective colloid. It acts as a stabilizer in foods. It is also employed in pharmaceuticals as a suspending agent and excipients for tablets. It is used as viscosity modifiers to stabilize the emulsions. It is used as a lubricant in artificial tears and it is used to characterize enzyme activity from endoglucanases.
