Trimethylammonium acetate is a natural product that was discovered by Scheibler (Scheibler C.1869,Scheibler Scheibler(Scheibler C.1869,Scheibler C.1870) discovered and isolated from betaine a natural product, according to its Latin name beta vulgaris will be named beta-in, its structure such as: CH3N + (CH3)2CH2COO-. Scheibler will be separated from the sugar beet from the compounds, with a quaternary ammonium salt structure or called ammonium structure of compounds called " betaine". When the methyl group in the natural betaine can be replaced by other substituents to obtain many alkyl aromatic betaines or alkyl amidopropyl betaines, etc.; the carbon bridge connecting the positive and negative charge centers can be grown to obtain propyl betaine, butyl betaine, etc.; the acetic acid group can also be replaced by other groups to obtain sulfoethyl, sulfo-propyl betaines or sulfuric acid (ethyl)-based betaines, phosphoric acid (ethyl)-based betaines, and other amphoteric surfactants.
Alkyl betaines
Using the quaternization of aliphatic tertiary amines, i.e., the reaction of N-alkyl-N,N dimethylamine with sodium chloroacetate in aqueous solution. Molecular formula: RN+(CH3)2CH2COO- where R is the carbon number 12~18. Alkyl betaine can be paired with various types of dyes, surfactants and cosmetic raw materials, it is stable to sodium hypochlorite, and should not be heated for a long time above 100℃. It has excellent stability under acidic and alkaline conditions and good compatibility. It has low irritation to skin, good biodegradability, excellent decontamination and sterilization, softness, anti-static, hard water resistance and rust resistance.
These products have excellent foaming ability, can make the hair soft, suitable for the preparation of shampoo, foam bath, sensitive skin preparations, children's detergents. Because of good water resistance, it is used to prepare hard water detergent. It can also be used as bactericide to kill many kinds of bacteria including tuberculosis, as fiber, fabric softener and antistatic agent, calcium soap dispersant, sterilization detergent and rubber industry, gel emulsifier, rabbit wool shrinking agent, fire-fighting foam agent, etc. It is also the synergist of the pesticide glyphosate. It is also used as a synergist of the pesticide glyphosate. It is also used as a dyeing auxiliary, antirust agent and metal surface processing auxiliary.
