Science
Mechanism of Action
Operating as a mild surfactant, Sodium Cocoyl Glycinate reduces water's surface tension, allowing it to emulsify and lift oils and impurities from the skin. It forms micelles that efficiently trap debris. Its unique small glycine head group minimizes disruption to the Stratum Corneum's vital lipids (Ceramides, Cholesterol, Fatty Acids), thereby maintaining skin hydration. It also enhances user experience by creating a rich, creamy lather.

Dusting Analysis
Sodium Cocoyl Glycinate is highly valued for its gentle yet effective cleansing properties and minimal impact on the skin barrier, making it a preferred choice, especially for sensitive skin formulations. It is not typically 'dusted' due to its recognized benefits.
The Formula
Formulation
Stability
This ingredient precipitates at pH levels below 5.0, making it unsuitable for highly acidic formulations. It exhibits stability within a pH range of 5.0 to 10.0, performing optimally between 7.0 and 9.0. It is water-soluble, miscible with alcohols, insoluble in volatile oils, and can be processed cold. It demonstrates excellent synergistic effects with fatty acids.
Synergies
- Fatty acids
- Other anionic surfactants
Conflicts
- Products with pH lower than 5.0
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) deems Sodium Cocoyl Glycinate safe for cosmetic use, subject to concentration limitations, typically up to 30% for the active ingredient. It is also reviewed and approved by the U.S. Food and Drug Administration (FDA).
