ACETYL CARBOXYMETHYL COCOYL GLYCINE.

Valuable / CHELATING

ACETYL CARBOXYMETHYL COCOYL GLYCINE is an ingredient derived from coconut oil fatty acids and glycine, primarily recognized for its chelating properties. It serves to enhance the stability and appearance of cosmetic formulations by neutralizing undesirable metal ions, while maintaining a low potential for irritation.

Summary

Chelating

Science

Mechanism of Action

This compound functions as a chelating agent, precisely binding to metal ions present in cosmetic matrices. By sequestering these ions, it prevents them from catalyzing degradation reactions that can compromise product integrity, lead to discoloration, or diminish the efficacy of other ingredients. Its molecular structure includes 'cocoyl' fatty acid components, indicative of coconut oil origin, and 'carboxymethyl' groups, where hydroxy groups are linked to a carboxymethyl moiety.

Stability

No specific optimal pH range for the stability of ACETYL CARBOXYMETHYL COCOYL GLYCINE has been precisely identified. However, related water-soluble compounds such as Sodium Cocoyl Glycinate and Carboxymethyl cellulose typically demonstrate broad stability across a pH range of approximately 3 to 11. The glycine component within this ingredient can also influence the pH dynamics of solutions.

CIR Status
Not reviewed
Sensitization risk Low

ACETYL CARBOXYMETHYL COCOYL GLYCINE itself has not undergone a direct Cosmetic Ingredient Review (CIR) assessment. However, the CIR has evaluated related ingredient classes, including 'Amino Acid Alkyl Amides' which encompass some acetylated amino acids and cocoyl glutamates. Glycine, a core component, has also been reviewed by CIR. The closely related Sodium Cocoyl Glycinate is approved for use and considered safe, with a minimal potential for slight irritation noted specifically for highly sensitive skin.
