Problems solved by technology

These carbon-based hair dyeing materials only cover the hair surface, are safe, non-toxic and non-allergic, but are either complicated to make, or the cost of raw materials is high. For example, the unit price of graphene is generally more than 1,000 yuan per gram, which limits its commercial promotion and use.
Among carbon-based dyeing black materials, carbon black has good colorability and chemical stability, is safe, non-toxic and low in price. The black particle size is small and easy to agglomerate, and the polar groups on the surface are less suitable for wetting, so the dispersion stability is poor [Printing and Dyeing, 2017, 43(18):5~10.], there are uneven coloring and color fastness when dyeing black hair with it Insufficient intensity and other problems, mostly only used in temporary hair dyes or as dyeing aids
If it can solve the problems of uneven coloring and insufficient color fastness of carbon black hair dye, it will be an ideal permanent black hair dye colorant

Embodiment 1

[0034] Anti-allergic hair dye in the present embodiment, by mass percentage 100%, is made up of following components:

[0035] Oxidation modified carbon black 0.5%,

[0036] Polymer material chitosan 4%,

[0037] Lemon Extract 2%,

[0038] The balance is deionized water.

[0039] Weigh the lemon extract (4g) of the prescription amount, add 30 parts by mass of deionized water (60g), heat to 40°C, stir until completely dissolved, then add the chitosan (8g) of the recipe amount, and stir for 20 Minutes later, add a prescription amount of oxidation-modified carbon black (1g), add deionized water to 100%, continue stirring for 30 minutes, cool to room temperature, and obtain a colloidal hair dye.

Embodiment 2

Abstract

The invention discloses an anti-allergic hair dye and a preparation method thereof, the anti-allergic hair dye comprises the following components by mass percentage concentration: 0.25-3% of oxidationmodified carbon black, 1-5% of high polymer material chitosan, 1-5% of a lemon extract, and the balance of deionized water, and can also comprise 0-2% of a walnut green seedcase extract. The hair dyedisclosed by the invention is simple in components; wherein the oxidation modified carbon black is good in dispersion stability, and other chitosan, the lemon extract and the walnut green seedcase extract components are all natural sources. The prepared hair dye product is safe and non-toxic, tests show that the hair dye product is non-irritant, has no sensitization reaction to skin, is simple inpreparation process, convenient to use and low in cost of oxidation modified carbon black, has greater price advantage compared with other carbon-based black dyeing materials such as carbon nanotubesand graphene, and is suitable for a wide range of people.

Description

technical field [0001] The invention relates to an antiallergic hair dye and a preparation method thereof. Background technique [0002] As a special-purpose cosmetic, hair dyes have been very active in the global cosmetic field in recent years, and the total demand for related products has grown at an average annual rate of more than 5% [Food and chemical toxicology, 2013,55: 8-17; Int . J. Cosmet. Sci., 2015, 37(5): 489-495.] At present, the annual hair dye market in my country alone is more than 5 billion yuan. With the improvement of people's living standards in our country, especially the further aging of the population structure, the number of silver-haired people is increasing, and the hair dye market will further expand, and the most demanded one is black hair dye. [0003] At present, most of the black hair dyes on the market are permanent oxidative hair dyes, and the hair dyes are mostly carried out under alkaline conditions. First, alkalis such as ammonia are used...
