Product Description

Product Description of Sodium carboxymethyl cellulose CAS#9004-32-4

Sodium carboxymethyl cellulose (CMC) is a water-soluble polymer forming thixotropic solutions. It keeps ingredients evenly suspended, widely used in pyrotechnic products.

It works as an efficient binder with low dosage and strong adhesion, ideal for strobe formulas. Yet its sodium content limits its use in most colored pyrotechnic mixtures.


Product Application of Sodium carboxymethyl cellulose CAS#9004-32-4

Sodium carboxymethyl cellulose (NaCMC) is anionic carboxymethyl cellulose sodium salt. Widely used in oral and external medicines for thickening, its aqueous solution can stably suspend powders for various pharmaceutical uses.
