Sodium carboxymethyl cellulose CAS#9004-32-4

Basic Information

Sodium carboxymethyl cellulose

Sodium carboxymethyl cellulose is a water-soluble anionic cellulose polymer that forms thixotropic solutions. It keeps powders suspended, provides adhesion, and functions effectively as a binder at low addition levels. Applications include pharmaceutical and external formulations, where it can thicken and stabilize suspensions, as well as pyrotechnic compositions and other systems requiring controlled dispersion and binding.

product description

Excellent Water Solubility: Fully water-soluble polymer that forms stable aqueous solutions, enabling easy processing and formulation.


Thixotropic Performance: Exhibits thixotropic behavior in water, providing effective suspension capability and helping maintain uniform dispersion of solid components.


Highly Efficient Binding Ability: Acts as a strong binder even at low dosage levels, minimizing interference with formulation performance while maintaining structural integrity.


Stable & Controlled Chemical Structure: Produced through carboxymethyl modification of cellulose and neutralized to its sodium salt form, ensuring consistent quality and reliable functional performance.

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.
