Stearic acid is one of the main long-chain fatty acids that make up oils and fats. It exists in animal fats, oils and some vegetable oils in the form of glycerides. Stearic acid is obtained by hydrolysis of these oils. Stearic acid is a kind of fatty acid widely existing in nature. It has the chemical properties of general carboxylic acid. Almost all oils contain stearic acid with different content. The content of stearic acid in animal fat is higher, such as 24% in butter, less in vegetable oil, 0.8% in tea oil and 6% in palm oil, but the content in cocoa butter is higher. Up to 34%.

1. Stearic acid is widely used in cosmetics, plasticizers, demolding agents, stabilizers, surfactants, rubber vulcanization
accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and
other organic chemicals.
2. Stearic acid can also be used as a solvent of oil-soluble pigments, crayon smoothing agent, wax paper polishing agent,
emulsifier of stearic acid glycerin, etc.
3. Stearic acid is also widely used in the manufacture of PVC plastic pipes, sheets, profiles and films. It is a thermal
stabilizer of PVC and has good lubricity and good light and thermal stability.

1. Widely used as a cold-resistant plasticizer, stabilizer, surfactant, release agent, rubber vulcanization accelerator, etc.
2. Used for the determination of water hardness, as an activator and diffuser of acidification.
3. For the preparation of soap, cosmetics, pharmaceuticals and other organic chemicals
4. Used as an emulsifier for oil-based drilling fluid. It can also be used as a lubricant and wetting agent in the rubber industry and textile industry.
5. Lubricant; Anti-binder; Gum sugar base agent; Defoamer and other food additives.
6. Used as a vulcanizing activator of natural rubber, synthetic rubber and latex, and as a raw material of plasticizer and
stabilizer of plastics.
7. determine the hardness of the water. Calcium, magnesium and lithium were determined by turbidimetry. Solvent for determination of relative molecular weight. Active agent for acidification
