SODIUM/MEA-PEG-3 COCAMIDE SULFATE.

Valuable / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING, SURFACTANT - FOAM BOOSTING, SURFACTANT - HYDROTROPE

SODIUM/MEA-PEG-3 COCAMIDE SULFATE is a multifunctional alkoxylated fatty amide, primarily functioning as a cleansing agent and surfactant in cosmetic formulations. It excels at reducing surface tension, aiding in the effective removal of oils and impurities, while also significantly improving foam volume and stability.

Summary

Cleansing Agent Emulsifier Surfactant - Foam Boosting Surfactant - Hydrotrope

Science

Mechanism of Action

As a surfactant, SODIUM/MEA-PEG-3 COCAMIDE SULFATE reduces the surface tension between liquids, allowing for the stable mixing of oil and water. This property is crucial for lifting and washing away lipid-based impurities and soil particles from the skin and hair. Furthermore, it acts as a foam booster, enhancing the volume, structure, and longevity of lather, and as a hydrotrope, increasing the solubility of other substances within a water-based solution.

Stability

This ingredient is a derivative of polyethylene glycols (PEGs), whose physical properties, including consistency, water solubility, and hygroscopicity, vary with molar mass. Formulators must prioritize minimizing impurities such as 1,4-dioxane and primary amines to ensure product safety and stability.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel deemed alkoxylated fatty amides, including this ingredient, safe for cosmetic use when formulated to be non-irritating. Strict avoidance in formulations where N-nitroso compounds could develop is advised, and manufacturers must minimize impurities like 1,4-dioxane and primary amines. The Scientific Committee on Consumer Safety (SCCS) has approved or restricted this substance under specific conditions outlined in Annex III of the EC Cosmetics Regulation. While the FDA lists it as Generally Recognized as Safe (GRAS) for food additives and household cleaners, this designation does not extend to cosmetic applications.
