CMC (Carboxymethyl Cellulose) detergent grade is a water-soluble polymer that acts as a thickener, stabilizer, and anti-redeposition agent in cleaning products. Different grades are available, distinguished by their substitution degree and viscosity, which determine their suitability for specific applications like high-viscosity liquid detergents or low-viscosity granulated detergents.
Properties and functions
Thickening: CMC increases the viscosity of liquid detergents, giving them a desirable consistency and preventing separation.
Stabilizing: It stabilizes the chemical components in a formulation, such as surfactants and suspended particles, and prevents them from settling out.
Anti-redeposition: In laundry detergents, it prevents loosened dirt from redepositing onto fabrics during the wash cycle.
Fast dissolving: Some grades are designed for rapid dissolution, making them convenient for various cleaning applications.
Anti-caking: Certain low-substitution grades are used in powdered detergents to prevent caking and maintain a free-flowing form.
Types and grades
CMC detergent grades are categorized by their chemical properties, such as substitution degree (DS) and viscosity.
High-substitution, High-viscosity: Excellent for thickening and soil suspension in liquid detergents.
Medium-substitution, Medium-viscosity: Offers a balanced combination of solubility and viscosity control.
Low-substitution, Low-viscosity: Favors fast dissolution and anti-caking properties for powder detergents.
Ultra-pure, Low-foam: A specialized grade with minimal foam, high biodegradability, and good compatibility with enzymes.
Application examples
Liquid detergents: Used to achieve the right thickness and stability.
Powder detergents: Prevents caking and ensures the product remains free-flowing.
Toothpaste: Creates a smooth, consistent paste and improves stability and texture.
Industrial cleaners: Stabilizes formulations and enhances cleaning efficiency.
