The product is white or slightly yellow particles or blocks, a mixture of 45% stearic acid and 55% palmitic acid, and contains a small amount of oleic acid, with a slight fatty smell.


Stearic acid is widely used in cosmetics, plastic cold-resistant plasticizers, release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners and pharmaceuticals. and other organic chemicals.

In addition, it can also be used as a solvent for oil-soluble pigments, a crayon adjuster, a polishing agent for wax paper, and an emulsifier for glyceryl stearate, etc. This product is used in the food industry as a lubricant, defoaming agent and raw material for food additives such as glycerol stearate, sorbitan stearate, sucrose ester, etc.

Stearic acid is used as a raw material for additives and a raw material for daily chemical products. It is widely used in the manufacture of Pv°C 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 PVC film processing and can prevent the finished film from being exposed to sulfide. Color Changing Rubber Industry Stearic acid plays an important role in the synthesis and processing of rubber.

Stearic acid is a widely used vulcanization activator 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 needs to be added as an emulsifier. When making foam rubber, stearic acid can be used as a foaming agent. Stearic acid can also be used as a release agent for rubber products.


Stearic acid is used in skin care products such as creams and cold creams to emulsify them into a stable, white paste.
