Problems solved by technology

[0004] In order to solve the above problems, the patent document CN109394571A discloses a composition containing an aqueous nonionic polyurethane dispersion, which can make the hair naturally strong and prolong the duration of the fullness of the hair. However, since the polyurethane is attached to the hair, it is not conducive to Cationic conditioners work attached to the hair and therefore are not ideal for antistatic effects on the hair

Abstract

The invention provides a water-based modified polyurethane dispersion. The water-based modified polyurethane dispersion is prepared from the following raw material components through reaction: S1, at least one diisocyanate; S2, macromolecular polyol; S3, polyglutamic acid; S4, at least one monohydric alcohol and/or dihydric alcohol with a main chain and/or a side chain containing a polyoxyethylene chain segment; S5, at least one diamine chain extender containing reactive hydrogen; S6, at least one dihydric alcohol micromolecule chain extender containing reactive hydrogen, namely a catalyst; S7, a low-boiling-point organic solvent; and S8, water. The water-based modified polyurethane dispersion has the advantages of good film-forming elasticity, high glossiness, good toughness, moderate hardness and non-sticky hand feeling, and can be used as a hair conditioner.

Description

technical field [0001] The invention relates to the field of cleaning and care, in particular to a water-based modified polyurethane dispersion and its use and hair conditioner prepared therefrom. Background technique [0002] With the continuous improvement of living standards, people continue to put forward new demands for personal cleaning products. At present, problems such as dry and frizzy hair, prone to static electricity and unmanageable hair are more and more concerned by people. It has become the simplest and most effective way to solve these problems through shampoo. [0003] Commercially available shampoos generally solve the problems of dry and frizzy hair, prone to static electricity and difficult to manage by adding cationic conditioning agents, such as polyquaternium salts or cationic guar gum. However, due to their good water solubility, most of them When shampooing and rinsing the lather, it gets washed away, making it less effective. In addition, some sh...
