What is Carboxymethyl cellulose (9004-32-4) used for?
Sodium carboxymethyl cellulose 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.
