Classification of betaine

Trimethylammonium acetate was discovered by Scheibler (Scheibler C.1869, Scheibler C.1870) and isolated from betaine as a natural product, named beta-in according to its Latin name beta vulgaris, and its structure is as follows: CH3N+(CH3) 2CH2COO-. Scheibler called this compound with a quaternary ammonium inner salt structure or ammonium structure "betaine" when it was isolated from sugar beet. When the methyl group in natural betaine can be replaced by other substituents to get many alkyl aromatic betaines or alkyl amide propyl betaines, etc.; the carbon bridge connecting the positive and negative charge centers can be grown to get propyl betaine, butyl betaine, etc.; the acetic acid group can also be replaced by other groups to get sulfoethyl and sulfopropyl betaines or sulfuric acid (ethyl)-based betaine, phosphoric acid (ethyl)-based betaine, etc. amphoteric surfactants. Quaternization of aliphatic tertiary amines is employed, i.e., the reaction of N-alkyl-N,N dimethylamine with sodium chloroacetate in aqueous solution. Molecular formula: RN+(CH3)2CH2COO- where R is 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.
