Used in cosmetics and personal care products as an emulsifier and thickening agent, stearic acid helps stabilize formulations in creams, lotions, and soaps. It is commonly found in makeup, especially in foundations and concealers, where it contributes to a smooth texture and improved spreadability. In skincare, it acts as an emollient, helping to soften and condition the skin. In industrial applications, stearic acid serves as a lubricant in the production of plastics, rubber, and textiles. It prevents materials from sticking to molds during manufacturing. It is also used in candle making to increase hardness and improve burn consistency. In pharmaceuticals, stearic acid is used as a binder and lubricant in tablet and capsule production, ensuring smooth processing and consistent release of active ingredients. Additionally, it finds use in food products as a release agent and texture modifier, particularly in confectionery and chewing gum.
