Problems solved by technology

[0004] But hair dye can cause hair damage on the one hand
During the hair dyeing process, a large amount of alkaline substances enter the hair and destroy the original protein, which will cause the dyed hair to become dry, lose luster and elasticity; on the other hand, hair dyes generally contain carcinogens, and hair dyes contact the skin , and heating is required during the hair dyeing process, causing carcinogens to enter the capillaries through the scalp, reach the bone marrow with the blood circulation, and act repeatedly on hematopoietic stem cells for a long time, resulting in the malignant transformation of hematopoietic stem cells and the occurrence of leukemia

Abstract

The invention relates to the technical field of hair dyes and particularly relates to a preparation method of a hair dye containing graphene and the hair dye. The preparation method of the hair dye containing graphene comprises the following steps: carrying out epoxy ring-opening reaction through epoxy modified silicon oil and secondary amine compound to obtain tertiary amine modified silicon oil;carrying out balanced reaction through octamethylcyclotetrasiloxane, amino-contained methyl dialkoxy silane, tertiary amine modified silicon oil and end blocking agent to obtain amino copolymerized silicon oil; carrying out quaternarization through amino copolymerized silicon oil and a quaternarization reagent to obtain amino-contained quaternarization silicon oil; dispersing Hummers-process graphene oxide in deionized water and then adding amino-contained quaternarization silicon oil, and treating to obtain the hair dye containing graphene. The hair dye containing graphene can be used for dyeing the hair to obtain yellow hair; the hair dye is free of damage to hair quality, is capable of enabling the hair to be softer and smoother, and is excellent in antistatic effect and long in hair color lasting time.

Description

technical field [0001] The invention relates to the field of hair dyes, in particular to a preparation method of a graphene-containing hair dye and the hair dye. Background technique [0002] A hair dye is a cosmetic product used to change the color of the hair, with the aim of changing the color of the hair. As people's living standards are getting higher and higher, hair dyeing has become more and more a normal life. [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 hair fiber. [0004] But hair dye can cause hair damage on the one hand. During the hair dyeing process, a large amount of alkaline substances en...
