Product Description

Product Description

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%.

The main production methods of industrial stearic acid are fractionation and pressing. The crude fatty acid is hydrolyzed by adding decomposing agent in hardening oil, and then the product is washed, distilled and decolorized. The by-product is glycerol.

Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles and films. It is a PVC heat stabilizer with good lubricity and good light and heat stability. In plastic PVC pipes, stearic acid is helpful to prevent coking during processing, and it is an effective heat stabilizer in PVC film processing, and it can also prevent the discoloration of finished films caused by exposure to sulfide.

Stearic acid is used in cream and cold cream to emulsify skin care products, so that it becomes a stable and white paste. Stearic acid is also the main raw material for making almond honey and milk. Soap stearate is widely used in cosmetics industry.

Stearic acid is widely used in cosmetics, plastic cold-resistant plasticizer, release agent, stabilizer, surfactant, rubber vulcanization accelerator, waterproof agent, polishing agent, metal soap, metal mineral flotation agent, softener, medicine and other organic chemicals.
In addition, it can also be used as a solvent for oil-soluble pigments, a crayon smoothing agent, a waxed paper polishing agent, and an emulsifier for glyceryl stearate.
