Octadecanoic Acid

Stearic acid, also known as octadecanoic acid, produced by oil hydrolysis, mainly for the production of stearate. Each gram is dissolved in 21ml ethanol, 5ml benzene.
Stearic acid are widely used as the basic raw materials of surfactants. Used as lubricant and stabilizer in plastics industry; Softener and fungicide in textile industry and household detergents; It is used as wax model in precision casting and soap base in grease industry.

APPLICATION

General Use
Mainly used in the production of stearate: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, potassium stearate.

Widely used in cosmetics, plastic cold-resistant plasticizer, release agent, stabilizer, surfactant, rubber vulcanization accelerator, water repellent, polish, metal soap, metal mineral flotation agent, softener, medicine and other organic chemicals.

In addition, it can also be used as solvent for oil soluble pigments, crayon smoothing agent, wax paper polishing agent, emulsifier of stearate glycerin, etc.

The product is used in the food industry as a lubricant, defoamer and food additives stearate glycerin, stearate sorbitan anhydride ester, sucrose ester and other raw materials. Used as auxiliary raw materials 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 stability. In plastic PVC pipes, stearic acid helps to prevent "coking" during processing, and is an effective heat stabilizer added in PVC film processing, while preventing discoloration of the finished film caused by exposure to sulfide.

Rubber industry
Stearic acid plays an important role in the synthesis and processing of rubber. Stearic acid is a vulcanizing active agent widely used in natural gums, synthetic rubber and latex, and can also be used as a plasticizer and softener. In the production of synthetic rubber process need to add stearic acid as emulsifier, in the manufacture of foam rubber, stearic acid can be used as a foaming agent, stearic acid can also be used as rubber products release agent.

Cosmetics industry
Stearic acid is used to emulsify two types of skin care products, such as cream and cold cream, so that it becomes a stable 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 cosmetics industry.
