beautyskincareemollient

In plain English

Oleyl Arachidate is a wax-like ingredient made from a fatty alcohol (oleyl alcohol) and a fatty acid (arachidic acid). In skincare, it acts as an emollient, meaning it helps soften and smooth the skin by forming a light, non-greasy film that reduces water loss. It also improves the texture of creams and lipsticks, making them feel silky and spread easily.
