Science
Mechanism of Action
This ingredient functions by significantly lowering the surface tension of liquids, which enables the efficient removal of dirt and excess oil from both skin and hair. As an emulsifier, it plays a critical role in stabilizing formulations by facilitating the harmonious blending of immiscible liquids, such as oils and water. Furthermore, it acts as a conditioning agent, enhancing product feel and contributing to a smooth, softening, and moisturizing effect that helps to retain moisture in the skin and hair.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed TEA-Lauroyl Methylaminopropionate, within the context of Triethanolamine (TEA) and its salts, as safe under specific conditions. For formulations designed for prolonged contact with the skin, the concentration of ethanolamines, including this ingredient, should not exceed 5%. It is considered safe for products intended for brief, discontinuous use followed by thorough rinsing. A critical safety precaution is to avoid co-formulation with N-nitrosating agents to prevent the potential formation of nitrosamines.
