Skin Benefits

Promotes smooth, uniform textures that help lift oily buildup and makeup from the skin, and encourages easy rinse-off with a cleaner after-feel.

Uses in Skincare & Cosmetics

Common in gel cleansers, milk cleansers, and makeup-removing lotions, and also used to help disperse actives in creams and serums.
