STEARIC ACID Chemical compatibility with O-rings, rubbers, & plastics

Stearic acid is a saturated fatty acid with the chemical formula C18H36O2. It is widely used in various industrial, chemical, and cosmetic applications, primarily as an emulsifier, thickening agent, and stabilizer. In the cosmetic industry, stearic acid is commonly used in the formulation of soaps, lotions, and creams, providing stability and improving texture. It is also employed in the production of candles, where it acts as a hardener and improves the burning properties. In the rubber industry, stearic acid is used as a processing aid and activator in the vulcanization of rubber. Proper handling and storage of stearic acid are essential to maintain its quality and prevent moisture absorption. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial to prevent skin and eye irritation and other health hazards. Its versatility and effectiveness in various applications make stearic acid a valuable chemical in numerous industries.
