Science
Mechanism of Action
This mild anionic surfactant functions via a dual-action mechanism. A hydrophobic coconut fatty chain efficiently reduces surface tension, enabling effective cleansing and lather formation, lifting impurities without stripping. Simultaneously, a hydrophilic L-glutamic acid group supports the skin and hair's natural moisture balance, contributing to a soft and hydrated post-wash feel. It also acts as an emulsifier, aiding in the stable mixing of oil and water.

Stability
TEA-Cocoyl Glutamate exhibits stability in acidic formulations and is compatible with weakly acidic pH systems. For optimal performance in rinse-off products, it is generally recommended to maintain a pH range between 5.5 and 6.5.
Conflicts
- Nitrosating agents (Due to the Triethanolamine (TEA) component, formulation with nitrosating agents can potentially lead to the undesirable formation of nitrosamines. Strict purity criteria are essential to mitigate this risk.)
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed TEA-Cocoyl Glutamate safe for use in cosmetics under current practices and concentrations, provided formulations are non-irritating. It is approved for use in the European Union, subject to specific restrictions outlined in Annex III of the EC Cosmetics Regulation. A key consideration is the Triethanolamine (TEA) component, which necessitates careful formulation to avoid co-presence with nitrosating agents, as this could lead to nitrosamine formation. Purity criteria are crucial to address this potential concern.
