Chemical formula C18H36O2 [4] Molecular weight 284.48 CAS Login Number 57-11-4 [4] EINECS Entry Number 266-928-5 [4] Melting point 67 to 72 �° C [4] Boiling point 361 �° C [4] Water soluble and insoluble Density 0.84 g/cm�³ White waxy transparent solid or yellowish waxy solid Should be used to produce stearate Security Description S37/39; S26; S16 Hazard symbol R11; R36/37/38 Production method Oil hydrolysis production 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.
Stearic Acid, E570,CAS No.57-11-4, is a saturated fatty acid with an 18-carbon chain manufactured through hydrolysis of triglycerides, available as WHITE FLAKE or white powder used as lubricants, softening and release agents in food production with E number E570. It is also essential ingredient in manufacturing of Potassium Stearate, Sodium Stearate and Glycerol Monostearate. Stearic acid is mainly used in the production of detergents, soaps, and cosmetics such as shampoos and shaving cream products. As an experienced Stearic Acid manufacturer and supplier, we has been supplying and exporting Stearic Acid for almost 10 years. Please be assured to buy from us.
