Used primarily in cosmetic formulations, N6-dodecanoyl-L-lysine functions as a surfactant and emulsifier, helping to stabilize mixtures of oil and water. It is valued for its skin-conditioning properties, enhancing the texture and feel of skincare and makeup products by providing a silky, non-greasy finish and absorbing excess sebum. Additionally, it acts as a mild cleansing agent, suitable for use in facial cleansers and makeup removers. Its compatibility with various ingredients allows versatile application in creams, lotions, serums, and powders.
