Lauric acid CAS#143-07-7
1. lauric acid Used for the preparation of alkyd resins, as well as wetting agents, detergents and pesticides2. Used for peeling vegetables and fruits with a maximum amount of 3.0g/kg.
3. Used as defoamer; GB 2760-86 provides for the spices allowed to use; used for the preparation of other food grade additives.
4. lauric acid is widely used in the surfactant industry and can be, according to the classification of surfactants, divided into cationic, anionic, non-ionic and amphoteric type. The surfactants types of dodecanoic acid are listed in the attached table of this item. Some surfactants of the derivatives of dodecanoic acid and dodecanol are also antiseptics, such as dodecyl dimethyl benzyl ammonium chloride (geramine), dodecyl dimethyl benzyl ammonium bromide (bromo-geramine) and dodecyl dimethyl (2-phenoxyethyl) ammonium bromide (domiphen bromide). The dodecyldimethyllammonium-2,4,5-trichlorophenolate in these derivatives can be used as citrus preservative. Dodecanoic acid also has many applications in plastic additives, food additives, spices and pharmaceutical industries.

Product Application of Lauric acid CAS#143-07-7
Given its foaming properties, the derivatives of lauric acid (h-dodecanoic acid) are widely used as a base in the manufacture of soaps, detergents, and lauryl alcohol. Lauric acid is a common constituent of vegetable fats, especially coconut oil and laurel oil. It may have a synergistic effect in a formula to help fight against mircoorganisms. It is a mild irritant but not a sensitizer, and some sources cite it as comedogenic.
Lauric Acid is a fatty acid obtained from coconut oil and other veg- etable fats. it is practically insoluble in water but is soluble in alco- hol, chloroform, and ether. it functions as a lubricant, binder, and defoaming agent.Factory and Equipment Show
