Stearic Acid Usage and Synthesis:

Stearic acid, molecular formula C18H36O2, is produced by hydrolysis of oils and fats and is mainly used in the production of stearic acid salts. It is a white or off-white slippery powder or crystalline hard mass. It has fine needle-like crystals with slight luster in its profile; it has a slight odor similar to grease and is tasteless. Slightly soluble in cold water, soluble in alcohol, acetone, easily soluble in benzene, chloroform, ether, tetra Carbon chloride, carbon disulfide, amyl acetate and toluene, etc. Non-toxic. Stearic acid exists in the form of glycerides in animal fats, oils and some vegetable oils, and these oils are hydrolyzed to obtain stearic acid. Stearic acid is obtained by hydrolysis of these oils. The industrial product is white or yellowish granules or blocks, a mixture of 45% stearic acid and 55% soft stearic acid, with a small amount of oleic acid and a slight fatty odor. Our company can provide three grades of stearic acid.

Pharmacokinetics of Stearic Acid:

Stearic acid is a fatty acid widely found in nature and is present in varying amounts in almost all fats and oils, with higher levels in animal fats, such as butter It can be as high as 24% in animal fats, less in vegetable oils, 0.8% in tea oil and 6% in palm oil, but up to 34% in cocoa butter. The main production methods of industrial stearic acid are Fractional distillation and pressing methods. Add decomposition agent to the hardened oil, then hydrolyze to get crude fatty acid, and then wash, distill and decolorize to get the finished product. Glycerin is also produced by-product. This product The product can be packed in hard carton or woven bag lined with plastic bag. Store in a cool, dry and ventilated place, away from fire and oxidizer. Store and transport according to general chemical regulations.

Clinical Application of Stearic Acid:

Fatty acids are widely used as the basic raw materials of surfactants, mainly in the following applications in China: vulcanizing active agent in rubber industry; lubricant and stabilizer in plastic industry; softener and bactericide in textile industry and household detergent; wax mold in precision casting and soap base in grease industry. It is mainly used in the rubber industry as a vulcanizing active agent; in the plastics industry as a lubricant and stabilizer; in the textile industry and household detergents as a softener and bactericide; in precision casting as a wax mold, and in the grease industry as a soap base. Widely used in cosmetics, plastics Cold plasticizer, mold release agent, stabilizer, surfactant, rubber vulcanization accelerator, water repellent, polishing agent, metal soap, metal mineral flotation agent, softening agent, pharmaceutical and other organic chemicals. Stearic acid is used as an emulsifier in two types of skin care products: snow creams and cold creams, thus turning them into stable and white creams. Stearic acid is also the main Stearic acid is also the main raw material for the production of almond nectar and milk liquids. Stearic acid saponified esters are more widely used in the cosmetic industry. In addition, stearic acid is also widely used in the manufacture of PVC plastic pipes, sheets, profiles and films, It is a heat stabilizer for PVC and has a very good performance in the manufacture of plastic pipes, sheets, profiles and films. It is a PVC heat stabilizer with good lubricity and good light and heat stabilization.
