Product Description Product OverviewStearic acid is a long-chain saturated fatty acid , typically derived from animal or vegetable fats (such as tallow or palm oil). It appears as a white, waxy solid with a melting point of approximately 69°C, is slightly soluble in water, and readily dissolves in organic solvents like ethanol and chloroform. It exhibits excellent lubricity, emulsifying properties, and chemical stability, along with being mild and non-irritating. As a versatile raw material, stearic acid is widely used in cosmetics, industrial, and pharmaceutical applications. In cosmetics, it serves as a thickener and emulsifier in creams and soaps, enhancing texture and stability. In the plastics and rubber industries, it acts as a lubricant or release agent to improve processing performance. The pharmaceutical industry utilizes its binding properties in tablet excipients. Additionally, its derivatives are used as food additives. Thanks to its natural origin, safety, and multifunctionality, stearic acid is a fundamental raw material across industries, offering a balance of performance and cost-effectiveness.
