Sodium carboxymethyl cellulose, 1000 cps

Product Introduction

Sodium Carboxymethyl Cellulose (CMC-Na) is an anionic water-soluble polymer derived from natural cellulose. The introduction of carboxymethyl groups improves the water solubility of cellulose and provides functional properties including viscosity enhancement, stabilization, suspension, and film formation.

CMC-Na is available in different viscosity grades and degrees of substitution, allowing researchers to select suitable polymer characteristics for specific applications. Commercial grades include low, medium, and high-viscosity materials.

Common functions include:

• Thickening agent
• Binder
• Stabilizer
• Suspending agent
• Film-forming polymer
• Rheology modifier
• Protective colloid

Mechanism / Principle

The functional behavior of Sodium Carboxymethyl Cellulose mainly originates from its cellulose backbone and negatively charged carboxymethyl groups.

• Water-soluble polymer behavior
  Carboxymethyl substitution enables cellulose derivatives to disperse and dissolve in water, forming viscous polymer solutions. 
• Viscosity enhancement
  Hydrated polymer chains increase solution viscosity and improve formulation stability.
• Colloidal stabilization
  CMC-Na can stabilize suspended particles and prevent aggregation in aqueous systems.
• Film formation
  Polymer chains can form flexible films after drying, supporting coating and surface-treatment applications.
• Binding interaction
  Its polymer structure enables adhesion and binding in pharmaceutical, ceramic, and material systems.
