Science
Mechanism of Action
This ingredient functions as a mild anionic surfactant by reducing surface tension, enabling effective cleansing, emulsifying, dispersing, wetting, penetrating, and solubilizing of dirt and impurities from skin and hair. For skin, it aids in maintaining moisture balance, enhances skin wetting for a smoother feel, and reduces tightness, resulting in soft, hydrated skin. In hair care, it promotes increased shine and manageability, while also minimizing static electricity. It exhibits good foaming properties and can act as a foam booster, particularly when combined with other surfactants.

Safety
Safety Profile
The CIR Expert Panel concluded that amino acid alkyl amides, including TEA-Cocoyl Alaninate, are safe in cosmetic applications when formulated to be non-irritating. Its use is subject to restrictions regarding nitrosamine levels as per Annex III of the EC Cosmetics Regulation, a general precaution for compounds containing triethanolamine. While the FDA does not pre-approve cosmetic ingredients, it is generally recognized as safe for its intended use when formulated appropriately.
