Lauric Acid CAS 143-07-7

Most are used as anionic surfactants, accounting for about 60%, some are used as nonionic surfactants, accounting for about 30%, and the rest are cationic and amphoteric surfactants.

Anions include sodium laurate (emulsifier, foaming detergent, emulsion polymerization), ammonium laurate, triethanolamine laurate (raw material for liquid detergent), metal laurate (zinc, cadmium, barium salt, metal soap and stabilizer agent), lauroyl sarcosinate (surfactant), lauryl ether sulfate (detergent, foaming agent); non-ionic surfactants include sorbitol monolaurate (emulsifying, dispersing, wetting agent), Polyoxyethylene sorbitan monolaurate (emulsifier, solubilizer, stabilizer), polyethylene glycol monolaurate (general purpose emulsifier), polyoxyethylene laurate (emulsion, liquid detergent), lauric acid Diethanolamide (foaming agent, shampoo), diethylene glycol laurate (emulsifying, dispersing agent) and lauric acid chloride (foam stabilizer, organic synthesis intermediate); cationic surfactants include laurylamine (cationic and Amphoteric surfactant, emulsification, dyeing aid, flotation agent, dispersant), lauryl trimethylamine chloride (dyeing aid, emulsification, dispersion, antistatic, softener) , laurylamine acetate (flotation agent, pigment surface treatment agent), lauryl dimethylamine (cationic surfactant), dilauryl monomethylamine (cationic surfactant), trilaurylamine (extraction of rare earth elements agent); amphoteric surfactants include lauryl betaine (washing, antistatic, foaming agent), lauryl dimethyl betaine (shampoo foaming, dyeing auxiliaries), imidazoline laurate and its derivatives (antistatic static agent). Lauric acid chloride is used as a UV absorber, lauroyl peroxide (peroxide), methyl laurate (fiber oil, cosmetic raw material), lauryl stearyl acrylate (adhesive), methyl laurate Esters (fragrance), Laurylaldehyde (fragrance).

In addition, lauric acid is an edible defoamer and spice that is allowed to be used in my country’s GB2760-1996.

Surfactants with bactericidal and disinfecting effects can be prepared from lauric acid and lauryl alcohol as raw materials. That is to say, this type of product can be used as both a surfactant and a disinfectant. Lauryl dimethyl benzyl ammonium chloride, also known as “geeramine” or 1227, is prepared by chlorinating and aminating lauryl alcohol and then condensing with benzyl chloride.

Germine is widely used in surgical instruments and wound disinfection. It has also been widely used in industry. For example, in the cooling water systems of large-scale chemical fertilizers, oil refining and alkylbenzene production equipment, it has achieved satisfactory results as a bactericidal algicide for circulating water. It is also widely used as a bactericidal disinfectant in agriculture and other fields, because compared with the traditional disinfectant formalin, it has the advantages of high efficacy, low cost, non-irritating, non-toxic and low corrosion, and is also an antibacterial agent for skin. Disinfectant. Dodecyl dimethyl benzyl ammonium bromide, also known as “bromogeramine”, has a similar effect to “geeramine”.

Lauryl dimethyl (2-phenoxyethyl) ammonium bromide, also known as “domiphene” or “disinfection”, is a disinfectant made from lauryl alcohol.

Dilaurate phthalate (DLP), produced by the condensation of phthalic anhydride and lauric acid, is used as a plasticizer for polyvinyl chloride and its copolymer resins. DLP has low volatility, good temperature and cold resistance, and can be used to make films with strong tensile strength and good flexibility. It can also be used for PVC-based floors, wall decorative panels, wire coverings, artificial leather, fire-fighting equipment, etc. Diethylene glycol dilaurate can be used as plasticizer, emulsifier, inhibitor and stationary liquid for gas chromatography analysis. Dilauryl thiodipropionate can be used as an antioxidant and stabilizer for polypropylene, polyethylene, polyvinyl chloride, ABS plastics, etc. It can also be used as a plasticizer and softener, and can be used as a component of food packaging materials . It can also be used as an antioxidant for rubber, grease, soap, lubricating oil, and grease, and is especially effective as a heat stabilizer for polypropylene processing. Dibutyltin dilaurate is a polyvinyl chloride stabilizer, mainly used in soft and semi-rigid polyvinyl chloride products, such as transparent films, pipes, artificial leather, etc. Its products of the same series include: monobutyl maleate dibutyl tin laurate, monooctyl maleate laurate, dibutyl tin laurate and more than ten varieties.

Thiamine disulfate monolauryl salt can be used in lubricants, stabilizers, cosmetic ingredients, thickeners, hydrophobic agents, etc. Zinc laurate can also be used in films for food packaging.

The following fragrances or fragrance intermediates can be directly synthesized from lauric acid: lauramide, ethyl laurate, phenyl laurate, lauryl alcohol, lauryl aldehyde, lauryl nitrile, lauryl ketone, lauryl formaldehyde, lauryl ether, etc.

Sodium laurate can be used in cleaning agent, pharmaceutical industry and organic synthesis raw material. Zinc salt, barium salt, calcium salt, etc. of lauric acid.

Methyl laurate is a raw material for organic synthesis. It can also be used as a fiber oil agent, a cosmetic additive, and as a stationary liquid for gas chromatography. It is an important organic intermediate. Lauryl Stearyl Phthaloacrylate can be used as a mold release agent.
