Best Quality Carboxymethyl Cellulose 99% Powder CAS NO (9000-11-7)

Carboxymethyl cellulose (CMC), identified by its CAS number 9000-11-7, is a modified cellulose derivative widely used in various industries for its versatile properties as a thickening agent, stabilizer, binder, and emulsifier. It is synthesized through the chemical modification of cellulose, typically derived from wood pulp or cotton fibers, by introducing carboxymethyl groups onto the cellulose backbone.

1. Chemical Modification: Introduction of Carboxymethyl Groups Carboxymethyl cellulose is produced by treating cellulose with sodium hydroxide and chloroacetic acid, resulting in the substitution of hydroxyl groups (-OH) on the cellulose chain with carboxymethyl groups (-CH2COOH). This modification imparts water solubility and enhanced functionality to the cellulose polymer.

2. Water Solubility: Hydrophilic Properties The incorporation of carboxymethyl groups renders CMC highly water-soluble, allowing it to disperse readily in aqueous solutions and form viscous colloidal suspensions. This solubility makes it suitable for a wide range of applications in aqueous systems, including food, pharmaceuticals, personal care products, and industrial formulations.

3. Thickening Agent: Enhancing Viscosity and Texture One of the primary functions of carboxymethyl cellulose is its role as a thickening agent in liquid formulations. By increasing the viscosity of aqueous solutions, CMC imparts desirable texture, body, and mouthfeel to a variety of products, including sauces, dressings, soups, beverages, and cosmetics.

4. Stabilizer and Emulsifier: Improving Stability and Homogeneity In addition to thickening, carboxymethyl cellulose acts as a stabilizer and emulsifier, helping to prevent phase separation, sedimentation, and creaming in emulsions and suspensions. Its ability to form stable colloidal dispersions enhances the shelf-life, appearance, and sensory attributes of many food and personal care products.

5. Food Industry Applications: Versatile Food Additive Carboxymethyl cellulose finds widespread use in the food industry as a multifunctional additive, contributing to the texture, consistency, and stability of various food products. It is commonly employed in bakery goods, dairy products, frozen desserts, confections, sauces, and beverages, among others, to improve quality and processability.

6. Pharmaceutical Formulations: Binder and Disintegrant In pharmaceutical formulations, carboxymethyl cellulose serves as a binder, disintegrant, and controlled-release agent in tablet formulations, facilitating drug delivery and dissolution. Its ability to swell and form gel-like matrices upon hydration aids in the release of active pharmaceutical ingredients in a controlled manner.

7. Personal Care Products: Enhancing Formulation Performance Carboxymethyl cellulose is used extensively in personal care and cosmetic products, where it functions as a thickener, stabilizer, and moisturizing agent. It imparts desirable rheological properties to lotions, creams, gels, shampoos, and toothpaste, enhancing their spreadability, consistency, and sensory appeal.

8. Oil and Gas Industry: Drilling Fluid Additive In the oil and gas sector, carboxymethyl cellulose is employed as a viscosifier and fluid loss control agent in drilling fluids. Its ability to provide rheological control and filtration control helps maintain wellbore stability, prevent fluid loss, and enhance drilling efficiency in challenging geological formations.

9. Textile and Paper Industries: Surface Sizing and Coating Carboxymethyl cellulose is utilized in the textile and paper industries for surface sizing, coating, and finishing applications. In textiles, it improves the strength, smoothness, and printability of fabrics, while in papermaking, it enhances paper strength, formation, and printability, contributing to the quality of the final product.

10. Safety and Regulatory Considerations: Generally Recognized as Safe (GRAS) Carboxymethyl cellulose is generally recognized as safe (GRAS) for use in food and pharmaceutical applications by regulatory authorities such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). However, adherence to established usage levels and quality specifications is essential to ensure product safety and efficacy.
