Detergent Grade CMC is a key additive in cleaning formulations, functioning as a soil anti-redeposition agent and viscosity regulator.

Its anionic structure binds to dirt particles, preventing them from reattaching to fabrics or hard surfaces during washing. This grade is engineered to enhance cleaning efficiency while maintaining compatibility with surfactants, builders, and other detergent ingredients—suitable for laundry, dishwashing, and industrial cleaners.
Parameter | Specification |
Appearance | White to yellowish powder |
Viscosity (2% solution, 25°C) | 5–40 cP (liquid detergents) or 100–300 cP (powder detergents) |
Degree of Substitution (DS) | 0.5–0.8 |
Purity | ≥65% |
pH Value (1% solution) | 7.0–11.0 |
Moisture Content | ≤10% |
Effective Anti-Redeposition: Reduces soil redeposition on fabrics and surfaces by 30–50% compared to formulations without CMC.
Foam Compatibility: Low foaming properties do not disrupt surfactant foam stability—critical for machine washing (laundry and dishwashers).
Hard Water Resistance: Performs reliably in hard water and high-salt detergent formulations, maintaining cleaning power.
Cost-Effective Performance: Low dosage requirement (0.5–2% by weight) delivers significant improvements in cleaning efficiency.
Laundry Detergents: Added to powders and liquids to keep dirt suspended in wash water, preventing graying of fabrics.
Dishwashing Liquids: Improves grease emulsification and prevents water spot formation on glassware, dishes, and utensils.
Industrial Cleaners: Enhances soil removal efficiency in heavy-duty formulations for machinery, equipment, and industrial surfaces.
Q: Which viscosity grade of Detergent Grade CMC is better for liquid detergents?
A: Low viscosity grades (5–40 cP) are preferred for liquid detergents, as they maintain pourability and prevent product thickening during storage.
Q: Is Detergent Grade CMC biodegradable?
A: Yes, it is readily biodegradable, meeting global environmental standards for cleaning products (e.g., EU ECOLABEL, US EPA guidelines).
