Carboxymethyl Cellulose Sodium (CMC Sodium)

Chemical Name: Sodium Carboxymethyl Cellulose
Synonyms: CMC, Sodium Cellulose Glycolate
CAS Number: 9004-32-4
Molecular Formula: C8H16NaO8

Description:

Carboxymethyl Cellulose Sodium (CMC Sodium) is a cellulose derivative, produced by chemically modifying cellulose with carboxymethyl groups. It is an anionic water-soluble polymer widely used for its thickening, stabilizing, and binding properties. CMC Sodium is known for its ability to form gels or solutions with high viscosity even at low concentrations, making it a versatile additive across industries such as food, pharmaceuticals, cosmetics, and more.

Applications:

1. Food Industry:
   • Acts as a thickener, stabilizer, and emulsifier in products like ice creams, sauces, and beverages.
   • Provides texture and viscosity control in processed foods.
2. Pharmaceuticals:
   • Used as a binder, disintegrant, and stabilizer in tablet formulations.
   • Functions as a thickening agent in liquid medicines, suspensions, and topical creams.
3. Cosmetics:
   • Adds texture and stability to creams, lotions, shampoos, and toothpaste.
   • Used as a film-former and water-retaining agent in personal care products.
4. Oil Drilling:
   • Serves as a thickening agent in drilling fluids to improve mud viscosity, control fluid loss, and stabilize the borehole.
5. Textile and Paper Industry:
   • Used as a sizing agent for improving the strength and smoothness of yarns and fabrics.
   • Acts as a surface-finishing agent and water retention aid in paper production.
6. Detergents:
   • Enhances the stability and viscosity of liquid detergents, ensuring proper suspension of ingredients.

Advantages:

• Versatile Thickener: Effective in a wide range of applications and industries.
• Water-Soluble: Dissolves readily in water to create highly viscous solutions.
• Stable in pH Variations: Stable over a broad range of pH levels, ensuring consistent performance in diverse formulations.
• Non-Toxic and Biodegradable: Safe for use in food and pharmaceutical applications.

Handling and Storage:

• Storage Conditions: Store in a dry, cool environment, protected from moisture and direct sunlight.
• Shelf Life: Typically 2 years when stored in sealed packaging under proper conditions.
• Handling Precautions: Avoid inhalation of dust and direct contact with skin or eyes. Wear appropriate protective equipment.
