Stearic acid is widely used in cosmetics, plastic plasticizer, release agent, stabilizer, surfactant, rubber vulcanization accelerator, waterproof agent, polishing agent, metal soap, metal mineral flotation agent, softener, pharmaceuticals and other organic chemicals. Stearic acid can also be used as solvent of oil soluble pigment, wax pencil smoothing agent, wax paper polish agent, emulsifier of stearic acid glyceride, etc.
Stearic acid is widely used in cosmetics as a thickener and hardener, helping to shape soaps. Also used as a surfactant, stearic acid has a powerful cleaning power that helps reduce the surface tension of water, allowing it to mix with oil and dirt on the skin's surface, making them loose and easily washed away. Stearic acid can also be used as an emulsifier, meaning that it can be combined with other substances (such as oil and water) that are usually separate and incompatible to keep cleansers smooth and milky.Stearic acid is also widely used in the manufacture of polyvinyl chloride plastic pipes, plates, profiles, and films. It is a heat stabilizer for polyvinyl chloride with good lubricity and good light and heat stabilization.
Application:
Widely used in cosmetics, plastic cold plasticizers, release agent, stabilizer, surfactant, rubber vulcanization agent, waterproofing agent, polishing agent, metal soap, softener, pharmaceuticals, and other organic chemicals.
