SODIUM COCOYL GLUTAMATE.

Valuable CAS 68187-32-6 / CLEANSING, SURFACTANT - CLEANSING

Sodium Cocoyl Glutamate is a gentle, amino acid-derived anionic surfactant originating from coconut oil and glutamic acid. It functions primarily as a cleansing agent, effectively removing impurities while producing a rich, stable lather suitable for all skin types, including sensitive.

Summary

Cleansing Surfactant Emulsifying Hair Conditioning

Science

Mechanism of Action

This mild anionic surfactant works by effectively binding to and removing dirt, excess oil, and impurities from the skin's surface. Its unique mechanism allows it to generate a rich, stable lather while simultaneously acting as an emulsifier to combine oil and water. Notably, it protects the skin's natural moisture barrier by minimizing the disruption caused by other surfactants and supporting the skin's physiological low pH. Upon enzymatic degradation within the skin, it contributes to natural moisturizing factors such as PCA, and it also aids in softening hard water for enhanced cleansing efficacy.

For effective cleansing and foaming as a primary surfactant, concentrations typically range from 5% to 25% active matter. Lower concentrations are utilized as co-surfactants to enhance product mildness and improve foam quality.

Key findings

  1. 01 Clinical research indicates that Sodium Cocoyl Glutamate is non-irritating at concentrations up to 10%, offering an effective, gentle alternative to traditional sulfate cleansing agents for sensitive and oily skin.
  2. 02 Studies confirm its safety for topical application on skin and hair up to 10% concentration, with no observed side effects.
  3. 03 It demonstrated no phototoxic effects in human studies at concentrations up to 5%.
  4. 04 At 5% concentration, it showed minimal solubilization of intercellular lipids compared to other surfactants, highlighting its ability to cleanse effectively without disrupting the skin's crucial barrier lipids.

Stability

This ingredient maintains optimal stability and efficacy within a pH range of 5.0 to 7.0. While it can withstand slightly more acidic conditions (down to pH 4), its foaming and cleansing performance may diminish. For rinse-off products, a pH between 5.5 and 6.5 is generally recommended. Formulators must adjust the final product pH, as the raw material typically has a higher pH (10-11.5).

Conflicts

  • Cannot be thickened by sodium chloride or similar salts.
  • Incompatible with cationic surfactants and certain other substances.
  • May react with azo and diazo compounds to produce toxic gases.
  • Capable of forming flammable gases when combined with strong reducing agents.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) panel has deemed Sodium Cocoyl Glutamate safe for use in cosmetics when formulated to be non-irritating. It is recognized as Generally Recognized As Safe (GRAS) by the FDA and holds a low hazard score of 1 from the Environmental Working Group (EWG). While one study reported severe irritation at 5%, this finding is largely contradicted by extensive research demonstrating its mild and well-tolerated nature.
