Stearic acid, with a chemical formula of C18H36O2 and a molecular weight of 284.48, is a compound called octadecanoic acid. It is produced by the hydrolysis of fats and oils, and is mainly used for the production of stearates.
use
Mainly used to produce stearates: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, potassium stearate.
Widely used to make cosmetics, plastic cold-resistant plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and others Organic chemicals.
In addition, it can also be used as a solvent for oil-soluble pigments, a crayon slip agent, a wax paper polish, and an emulsifier for glyceryl stearate.
The product is used as a lubricant, defoamer and food additives in the food industry as a raw material for glyceryl stearate, sorbitan stearate, and sucrose esters. Used as raw material for additives and raw materials for daily chemical products.
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 stabilization. In plastic PVC pipes, stearic acid helps prevent "scorching" during processing. It is an effective heat stabilizer added in the processing of PVC film, and it can also prevent the finished film caused by exposure to sulfide. Discoloration.
Rubber industry
Stearic acid plays an important role in the synthesis and processing of rubber. Stearic acid is a vulcanization activator widely used in natural rubber, synthetic rubber and latex. It can also be used as a plasticizer and softener. In the process of producing synthetic rubber, stearic acid must be added as an emulsifier. In the production of foam rubber, stearic acid can be used as a foaming agent, and stearic acid can also be used as a release agent for rubber products.
Cosmetics industry
Stearic acid is used for emulsification in two types of skin care products, vanishing cream and cold cream, so that it becomes a stable and white paste. Stearic acid is also the main raw material for making almond honey and milk. Stearic acid soap esters are more widely used in the cosmetics industry.
