Sodium Carboxymethyl Cellulose (CMC) | CAS 9004-32-4 | E466, Thickener, Stabilizer & Binder

 Product Overview

Sodium Carboxymethyl Cellulose (CMC, CAS 9004-32-4, E466) is a natural, water-soluble anionic cellulose derivative processed from high-purity plant cellulose. It has multiple viscosity  and acid-resistant models.  As a multifunctional, cost-effective texture modifier and rheology regulator, CMC is most widely consumed in the food industry,  daily chemical and paper manufacturing fields. It offer reliable thickening, stabilizing, suspending, film-forming and moisture-locking effects to enhance product texture, structural stability and shelf performance. Its application in pharmaceutical formulations.

Product Functions 

1.Thickening Function: It increases the viscosity of aqueous systems to build smooth and consistent texture, improving mouthfeel and consistency for food, daily chemical and paper coating systems.

2.Stabilizing & Suspending Function: It forms a stable colloidal network to suspend solid particles, preventing sedimentation, layering and phase separation in beverages, toothpaste and other liquid or paste products.

3.Water-retention Function: It locks moisture inside the matrix, reduces water loss, delays aging and maintains soft texture for food, personal care items and paper products.

4.Film-forming Function: It forms a uniform protective film on the material surface, offering moisture barrier and surface protection for multiple applications.

5.Anti-crystallization & Binding Function: It inhibits ice and sugar crystal growth in food systems, and improves binding strength to optimize the physical structure of finished products.

Applications

1. Food Industry:  CMC is the most widely used water-soluble colloid in the food industry. It serves as a thickener, stabilizer, suspending agent and water retention agent in various beverage, dairy, frozen dessert, bakery, flour product, confectionery and convenience food systems. It effectively stabilizes product state, suspends solid particles, prevents layering and precipitation, controls ice crystal and sugar crystal formation, locks moisture to delay food aging, and significantly improves product texture, taste and shelf stability.

2.Daily Chemical Industry: It is commonly applied in toothpaste, shampoo, body wash and skin care products. CMC acts as a thickener, emulsifier and shaping agent to maintain uniform paste consistency, prevent water separation and solid precipitation, enhance product lubrication and improve overall formulation stability.

3.Paper Manufacturing Industry:  Industrial grade CMC is widely used in paper surface sizing and coating processing. It improves paper surface smoothness, enhances tensile strength and folding resistance, reduces paper powder falling, and optimizes printing adaptability of finished paper.

4.Pharmaceutical Industry : is occasionally used as a small-dose binder and stabilizer in partial pharmaceutical preparations with very low consumption.

Package and Storage

Packaging: Standard packaging adopts 25kg net weight kraft paper bags with inner PE waterproof liners, ensuring moisture-proof and dust-proof performance during transportation and storage. Large-scale bulk packaging including 500kg and 1000kg jumbo bags is available for industrial-grade orders. Customized packaging specifications can be provided according to customers’ personalized requirements.

Storage: Store the product in a cool, dry, clean and well-ventilated warehouse environment.
