Abstract

The invention provides a production method of polyquaternium-10. The production method comprises the following steps: preparing cationic etherifying agent ETA and preparing polyquaternium-10 by reaction between cationic etherifying agent and hydroxyethyl cellulose. The preparation method of the cationic etherifying agent ETA comprises the following steps: generating cationic etherifying agent ETA by reaction between epoxy chloropropane and trimethylamine, washing, and drying the cationic etherifying agent ETA. The preparation method of the cationic etherifying agent ETA is characterized by also comprising the step of refining after drying the cationic etherifying agent ETA, wherein the refining step particularly refers to the operation of carryin gout gas suction filtering for 2-3 hours at 30-50 DEG.C in a vacuum environment of -0.081Mpa to -0.1Mpa at a stirring speed is 40-50r / min. The prepared polyquaternium-10 has very good quality, high light transmittance (97.5-99.5%) and the ash content being not more than 3% and has 0-2 gel particles (4cm<2>); and the prepared polyquaternium-10 is whiter and uniform.

Description

technical field [0001] The invention relates to the field of chemical product production, in particular to a production method of polyquaternium-10. Background technique [0002] Polyquaternium-10 is a cationic cellulose polymer, compatible with anionic, cationic, nonionic and zwitterionic surfactants, low irritation, its unique cationic properties can repair damaged hair protein matrix, maintain Moisturizes the hair, giving the hair superior combing properties and a shiny and smooth feel.
