Abstract

The present invention discloses a color siloxane end-capped aqueous polyurethane hair dye and a preparation method thereof, and relates to the field of cosmetics. The hair dye comprises the followingcomponents in weight percentages: 10-80% of a color siloxane end-capped aqueous polyurethane emulsion, 0.1-1% of a thickener, 0.5-5.0% of sodium hyaluronate, 1.0-5.0% of amino acids, 1.0-5.0% of vitamin E, 0-5.0% of hydrolyzed proteins and the balance deionized water. The preparation method is as follows: the raw materials are taken in the amount according to the formula; and the raw materials areadded into a stirrer to be stirred evenly at a high speed of 800 rpm / min. The prepared color siloxane end-capped aqueous polyurethane hair dye is prepared by connecting dye molecules to a water-basedpolyurethane chain end-capped by a siloxane coupling agent through a chemical reaction, and the prepared color macromolecule hair dye has extremely excellent effects of adhesion and shaping, and at the same time has good shampoo resistance.

Description

technical field [0001] The invention belongs to the field of cosmetics, in particular to a colored silicone-terminated water-based polyurethane hair dye and a preparation method thereof. Background technique [0002] Hair dyeing has become a fashion. Young people can change the color of their hair according to their mood, and match their clothing and makeup to fully display their individuality. Walking on the street, you will find fashionable men and women using vivid and bright colors such as dark brown, linen, and wine red. Dress up a beautiful landscape, and currently hair dyes mainly contain three categories, namely permanent hair dyes, semi-permanent hair dyes and temporary hair dyes. [0003] Permanent hair dyes are mainly divided into oxidative hair dyes, inorganic hair dyes, and natural Chinese medicine hair dyes. [0004] Oxidative hair dye is the most widely used one at present, also known as permanent hair dye. Oxidative hair dye is mainly composed of color devel...
