About this ingredient

C18-21 Alkane is a mixture of saturated hydrocarbons with 18 to 21 carbon atoms, derived from petroleum or synthetic sources. It functions as an emollient and occlusive agent in cosmetic formulations, providing a lightweight, non-greasy barrier that helps retain skin moisture and improve product spreadability. It is commonly used in sunscreens, moisturizers, and other personal care products for its smooth sensory profile and stability.
