Abstract

The invention belongs to the technical field of chemical products, synthesis of the chemical products, and textile posttreatment, and particularly relates to an alkyl polyhydroxy quaternary ammonium salt and a preparation method and application of the alkyl polyhydroxy quaternary ammonium salt. The structural formula of the alkyl polyhydroxy quaternary ammonium salt is shown in the description. The preparation method of the alkyl polyhydroxy quaternary ammonium salt comprises the step of adding CH2CHOHCH2OH to RNH2 for three times for reaction to obtain the alkyl polyhydroxy quaternary ammonium salt. The alkyl polyhydroxy quaternary ammonium salt has the advantages that the alkyl polyhydroxy quaternary ammonium salt is in a tetrahedral structure, an R group is on one side, a CH2CHOHCH2OH group is on the other three sides, the alkyl polyhydroxy quaternary ammonium salt is excellent in conditioning property, moisture retention and water solubility, the difficult problems that the alkyl cation quaternary ammonium salt only has the conditioning property but does not have the moisture retention property or is poor in moisture retention property and water solubility are solved, so that the alkyl polyhydroxy quaternary ammonium salt not only can be widely used as a conditioning agent and a wetting agent in the products like a hairdressing gel, a hair conditioner, shampoo and a showergel, but also can be used as a softening agent in the products like a laundry detergent and in the textile posttreatment.

Description

technical field [0001] The invention belongs to the technical field of chemicals and their synthesis and textile post-treatment, and specifically relates to an alkyl polyhydroxy quaternary ammonium salt, its preparation method and application. Background technique [0002] Cationic quaternary ammonium salts, especially alkyl cationic quaternary ammonium salts are the main raw materials for the production of hair care products. The main effect of the alkyl cationic quaternary ammonium salt is that the alkyl cationic quaternary ammonium salt is adsorbed on the hair by the charge of its cation, and the long carbon chain in its molecular structure has both softening effects on the hair and can achieve Antistatic and antibacterial purposes, so as to achieve the function of hair care. [0003] Existing known cationic quaternary ammonium salt close to the patent of the present application has: [0004] (1) Alkyl (C 12-14 、C 18-16 or C 22 ) Trimethylammonium chloride, although ...
