Lauric acid properties, uses and production process Physical and chemical properties Lauric acid, also known as dodecanoic acid, is a saturated fatty acid with 12 carbon atoms. At room temperature, it is a white needle-like crystal, with a slight fragrance of laurel oil. Insoluble in water, soluble in organic solvents such as ether, etc., slightly soluble in and Although it is called lauric acid, it only accounts for 1-3% of the laurel oil content. At present, vegetable oils with high lauric acid content are found to be coconut oil 45-52%, oil palm seed oil 44-52%, babassu seed oil 43-44%, etc. Although lauric acid is a saturated fatty acid, it has a lower risk of cardiovascular disease than other saturated fatty acids. The biggest effect of lauric acid is its antimicrobial ability, which can improve immunity, many people find that after ingesting lauric acid, the antiviral ability is greatly improved, such as flu, fever, herpes, etc., lauric acid can also relieve antibiotic resistance, reduce the risk of heart disease and so on. For young women, one of the great benefits of lauric acid is skin care, and some studies have found that its skin care effect is much better than that of some well-known cosmetics. Main uses and functions 1. Lauric acid is mainly used as a raw material for the production of alkyd resins, wetting agents, detergents, pesticides, surfactants, food additives and cosmetics. This product is often used as a lubricant and has a variety of functions such as lubricant and vulcanizing agent. However, due to its corrosive effect on metal, it is generally not used for plastic products such as wires and cables. This product is most widely used in the surfactant industry, and can also be used in the spice industry and the pharmaceutical industry. 2. It is used as a surface treatment agent for the preparation of bonding. It is also used in the manufacture of alkyd resins, chemical fiber oils, pesticides, synthetic fragrances, plastic stabilizers, anti-corrosion additives for and lubricating oils. It is widely used in the manufacture of various types of surfactants, such as cationic types such as lauramine, lauricrile, trilauramine, lauryl lauryl trimethylammonium salt, etc.; Anionic types include sodium lauryl sulfate, laurate sulfate, triethanol ammonium lauryl sulfate, etc.; The zwitterionic types include lauryl betaine, imidazoline laurate, etc.; Non-ionic surfactants include polyL-alcohol monolaurate, polyoxyethylene laurate, glyceryl laurate, polyoxyethylene ether, diethanolamide laurate, etc. In addition, it is also used as a food additive and in the manufacture of cosmetics. 3. Lauric acid is a raw material for the production of soaps, detergents, cosmetic surfactants and chemical fiber oils. Toxic natural fatty acids, non-toxic. Safe for use in food (FDA, §172.860, 2000). LD5012g/kg (rat, oral). Usage limit FEMA (mg/kg): soft drinks 15, cold drinks 16, candy 2.4, baked goods 39, puddings 25, fats and fats 315. GB2760-1996: 3.0g/kg for fruit and vegetable peeling.
