Stearic acid Use and Manufacturing

Used for water hardness determination, also used as acidification activator and diffuser. Uses Widely used as plastic cold-resistant plasticizer, stabilizer, surfactant, release agent, rubber vulcanization accelerator, etc. Lubricant; anticaking agent; gum base; defoamer and other food additives (glyceryl stearate, sorbitan stearate, sucrose ester, etc.) manufacturing raw materials. Used as an emulsifier for oil-based drilling fluids. It can also be used as lubricant and wetting agent in rubber industry and textile industry. Used as a vulcanization active agent for natural rubber, synthetic rubber (except butyl rubber) and latex, and also as a raw material for plasticizers and stabilizers. In medicine, it is used to prepare ointments, suppositories, etc., and also to make cosmetics, candles, waterproofing agents, polishes, etc. This product is used as a lubricant, defoamer and food additives in the food industry as raw materials for glyceryl stearate, sorbitan stearate, and sucrose esters. It can be used as a standard for gas phase analysis and also used in the preparation of soap, cosmetics, pharmaceuticals and other organic chemicals. Determine the water hardness. Calcium, magnesium and lithium are measured in the turbidimetric method. Determine the relative molecular weight of the solvent. Active agent that promotes acidification. Commercial stearic acid is actually a mixture of 45% stearic acid and 55% palmitic acid, and contains a small amount of oleic acid, which has a slightly fatty smell.
