Science
Mechanism of Action
Disodium Cocoyl Glutamate functions as a mild anionic surfactant by significantly lowering surface tension between different components within a product or on the skin. Its unique structure, featuring both hydrophilic (water-attracting) and hydrophobic (oil-attracting) segments, enables it to encapsulate and emulsify surface dirt, oils, and contaminants into spherical micelles. These micelles can then be easily rinsed away with water, providing thorough cleansing without stripping the skin's essential natural oils. This action supports the skin's healthy moisture barrier, helps prevent dehydration, and contributes to the regulation of skin pH levels. Furthermore, it acts as an emulsifier, ensuring the stable combination of water and oil-based ingredients in a formulation.

Key findings
- 01 Considered safe for use in rinse-off products, effectively performing as a primary or secondary surfactant within a concentration range of 2% to 30%.
- 02 Demonstrated non-irritating properties for the skin at concentrations up to 10%.
- 03 Exhibited a prolonged degreasing effect, contributing to the prevention of reactive seborrhea and reducing conditions conducive to acne development, a superior performance when compared to Sodium Laureth Sulfate.
- 04 Recommended for best cleansing results at a 30% concentration, particularly when utilized as a primary surfactant. For secondary surfactant applications, a range of 5-20% is suggested.

The Formula
Formulation
Stability
The raw ingredient itself typically presents a pH in the range of 8.0-10.5. For optimal skin compatibility within the final product, the formula's pH should be adjusted to a weakly acidic range, ideally between 5-6. This ingredient demonstrates robust stability across a wide pH spectrum and performs effectively even in hard water. It can be readily incorporated into solid or cream-based products without requiring heat, although heating can aid dissolution.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has determined Disodium Cocoyl Glutamate safe for use in cosmetics, subject to specific concentration and use limitations, with a maximum recommended concentration of 30%. It is generally regarded as a safe ingredient that does not typically cause adverse effects on skin or hair. However, the European Chemicals Agency (ECHA) in REACH registrations indicates a potential for serious eye irritation, thus recommending a patch test for user safety. It holds certifications from ECOCERT, NaTrue, and BDIH, affirming its suitability for natural cosmetic formulations.
