Mainly used in the production of alkyd resin, wetting agent, detergent, pesticides, surfactants, food additives and cosmetics raw materials. This product is often used as a lubricant, with lubricant and vulcanizing agent and other functions. But because of the corrosion of metal, it is generally not used for wire, cable and other plastic products. This product is widely used in the surfactant industry, but also can be used in the spice industry, pharmaceutical industry.

Used as a surface treatment agent for preparing adhesives. Also used in the manufacture of alkyd resin, chemical fiber oil agent, insecticide, synthetic flavor, plastic stabilizer, gasoline and lubricating oil anti-corrosion additives. A large number of used in the manufacture of various types of surfactants, such as cationic lauryl amine, lauryl nitrile, trisyllauryl amine, lauryl dimethylamine, lauryl trimethyl ammonium salt; The anionic type includes lauryl sulfate sodium, lauryl sulfate salt, lauryl sulfate triethyl ammonium salt; Amphoteric ionic type lauryl betaine, imidazoline laurate, etc.; Nonionic surfactants include polyL - alcohol monolaurate ester, polyoxyethylene laurate ester, glycerin laurate polyoxyethylene ether, laurate diethanolamide, etc. In addition, it is also used as a food additive and in the manufacture of cosmetics.

Lauric acid is used in the production of soaps, detergents, cosmetic surfactants and chemical fiber oils.
