SODIUM COCOYL/HYDROGENATED TALLOW GLUTAMATE.

Valuable / CLEANSING, SURFACTANT - CLEANSING

Sodium Cocoyl/Hydrogenated Tallow Glutamate is an amino acid-derived anionic surfactant and cleansing agent. Valued for its exceptional mildness, it effectively purifies the skin while actively preserving its natural moisture barrier.

Surfactant Cleansing Agent Emulsifier Foaming Agent Hard Water Softener

Science

Mechanism of Action

This ingredient functions by decreasing the surface tension of the skin's outermost layer, the stratum corneum, facilitating the efficient removal of impurities and excess oil. As a non-delipidating acylglutamate, it selectively extracts squalane without disrupting vital barrier lipids such as cholesterol, thereby minimizing barrier compromise. It also contributes to luxurious foam formation and can act as an emulsifier, stabilizing oil and water components in formulations.

Key findings

  1. 01 At 5% concentration, Sodium Cocoyl Glutamate demonstrated superior mildness and the least solubilization of intercellular lipids compared to other surfactants, effectively extracting squalane while preserving essential barrier lipids like cholesterol.
  2. 02 Aqueous solutions of Sodium Cocoyl Glutamate (up to 30%) are widely utilized in gentle cleansing formulations, including baby care products and facial cleansers.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The CIR Expert Panel deems Sodium Cocoyl/Hydrogenated Tallow Glutamate safe under current cosmetic use practices and concentrations, provided formulations are non-irritating. Manufacturers must minimize residual peptide production and ensure ingredients containing Triethanolamine (TEA) have Diethanolamine (DEA) levels not exceeding 0.64%. Products must not allow N-nitroso compound formation, and any animal-derived components must be free of pathogenic agents. Sodium Cocoyl Glutamate, a similar ingredient, is generally recognized as safe (GRAS) by the FDA for cosmetic applications.
