Embodiment 1

[0029] A hair dye, composed of the following raw materials by mass percentage: 10% ethanol, 4% isopropanol, 6% benzyl alcohol, 0.10% HC yellow 4, 0.30% HC red 3, 20.1% HC blue, 0.80% hydroxyethyl cellulose, 0.50% acrylate / octylacrylamide copolymer, 0.50% AP-8087, 0.20% hydrolyzed keratin, the balance deionized water; the mass of all raw materials The sum of the percentages is 100%.

[0030] The preparation method of the hair dye: Stir and mix the raw materials evenly according to the formula quantity to obtain a mixed liquid; use a pH regulator to adjust the pH value of the mixed liquid to 3.0 to obtain the hair dye. The pH regulator is a mixture of sodium hydroxide and citric acid.

Embodiment 2

[0032] A hair dye consisting of the following raw materials in terms of mass percentage: 10% ethanol, 5% isopropanol, 7% 1,3-butanediol, 8% benzyl alcohol, 0.30% HC yellow 5 , 0.60% HC red 3, 0.1% HC blue 2, 1.50% hydroxyethyl cellulose, 2.0% acrylate / octylacrylamide copolymer, 2.0% AP-8087, 0.50% hydrolyzed keratin , the remaining amount of deionized water; the sum of the mass percentages of all raw materials is 100%.

[0033] The preparation method of the hair dye: Stir and mix the raw materials evenly according to the formula quantity to obtain a mixed liquid; use a pH regulator to adjust the pH value of the mixed liquid to 4.0 to obtain the hair dye. The pH regulator is a mixture of sodium hydroxide and citric acid.

Embodiment 3

[0035] A hair dye consisting of the following raw materials in terms of mass percentage: 10% ethanol, 5% isopropanol, 3% dipropylene glycol, 2% 1,3-butanediol, 8% benzyl alcohol, 0.40% of Basic Red 51, 0.2% of HC Red 3, 0.20% of Basic Yellow 87, 1.20% of hydroxyethyl cellulose, 1.0% of polyvinylpyrrolidone / hexadecene copolymer, 1.20% of KF-8020, 0.50% hydrolyzed collagen, the rest deionized water; the sum of the mass percentages of all raw materials is 100%.

[0036] The preparation method of the hair dye: Stir and mix the raw materials evenly according to the formula quantity to obtain a mixed liquid; use a pH regulator to adjust the pH value of the mixed liquid to 5.0 to obtain the hair dye. The pH regulator is a mixture of sodium hydroxide and citric acid.

Abstract

The invention discloses a hair dye, which is composed of the following raw materials in percentage by weight: 20.0 to 30.0% of organic solvent, 0.50 to 1.0% of direct dye, 0.80 to 1.50% of thickening agent, 0.50 to 2.0% of polymer resin, 0.50 to 2.0% of amino end group polysiloxane, 0.20 to 0.50% of protein hydrolysate, and the balance being deionized water. The provided hair dye has a very good dyeing performance, is capable of improving the color fastness and performance on resisting shampoo washing, and effectively solves the problem of easy fading.

Description

technical field [0001] The invention relates to a hair dye, in particular to a single-dose semi-permanent hair dye resistant to shampoo washing and high dyeing fastness. Background technique [0002] Existing hair dyes are divided into three classes of temporary hair dyes, semi-permanent hair dyes and permanent hair dyes by dyeing fastness. Temporary hair dyes fall off after shampooing once, semi-permanent hair dyes can withstand 6-12 shampoo washes, and permanent hair dyes have higher washing fastness and can generally last for 1-3 months (Document 1). The dyes used in semi-permanent hair dyes are mainly dyes with relatively low molecular weight, which can penetrate into the outer skin and part of the skin, including nitrophenylenediamine, nitroaminophenol, aminoanthraquinone, naphthoquinone, azo, alkaline, reactive and various dyes such as metallized dyes. The single-agent non-oxidative semi-permanent hair dye does not use oxidizing agents such as hydrogen peroxide, and ...
