Stearic Acid is a vegetable-derived oily acid, most usually used to thicken and maintain cosmetic formulations. Stearic acid is useful as an ingredient in making candles, soaps, plastics, oil pastel, cosmetics and softening rubber. Stearic acid is used to harden soaps, particularly those made with vegetable oil, that otherwise tend to be very soft.
Used as a thickening agent in lotions, Stearic Acid can also be used as a hardening agent in stick products and bar soaps, and in candles to increase the melting point.
