Problems solved by technology

[0004] However, hair dyes generally contain carcinogens. When the hair dye contacts the skin and is heated during the hair dyeing process, the carcinogens enter the capillaries through the scalp and reach the bone marrow with the blood circulation. occurrence of leukemia
An article in the French "60 Million Consumers" magazine stated that the nature of many ingredients in hair dyes is not yet fully known, and some ingredients may be harmful to health and may even cause cancer

Abstract

The invention relates to the technical field of hair dyes, in particular to a preparation method of a graphene hair dye and the graphene hair dye. In the present invention, 2,3-epoxypropyltrimethylammonium chloride and amino silicone oil are subjected to ring-opening reaction to obtain amino-containing quaternized silicone oil; Hummers method graphene oxide is dispersed in deionized water and then added with amino-containing quaternized silicone oil. Silicone oil treatment to obtain aminoquaternized graphene oxide; add aminoquaternized graphene ethanol solution to react with reducing agent to obtain aminoquaternized graphene and then disperse in water to obtain graphene hair dye. The graphene hair dye of the present invention can be used for hair dyeing to obtain black hair without damaging the hair quality, the hair is more supple, the antistatic effect is good, and the hair color lasts for a long time.

Description

technical field [0001] The invention relates to the field of hair dyes, in particular to a preparation method of a graphene hair dye and the graphene hair dye. Background technique [0002] Hair dye is a cosmetic product that colors the hair. As people's living standards are getting higher and higher, hair dyeing has become more and more a normal life. According to a CCTV international network survey, among the more than 2,600 people surveyed, more than 90% have dyed their hair, and about half of the respondents started dyeing their hair before the age of 30. [0003] At present, the mainstream semi-permanent hair dyes on the market use relatively small molecular weight dye molecules to penetrate into the hair epidermis, and some of them enter the cortex; the mainstream permanent hair dyes penetrate the dye intermediates and couplers into the hair cortex. Oxidation reactions occur, coupling and condensation reactions form larger dye molecules, which are enclosed in the hai...
