Graphene-modified hair dye

Abstract

The invention relates to a graphene-modified hair dye, which includes a coloring agent and a color developing agent, wherein the coloring agent comprises, by mass, 5.0-15.0 parts of graphene-modifiedgallic acid, 10.0-15.0 parts of an auxiliary agent, 15.0-25.0 parts of a cosolvent, and 50.0-60.0 parts of distilled water. Gallic acid is modified with graphene, so that graphene exists after dyeingwith the coloring agent and has a far-infrared physiotherapeutic hair care effect. Gallic acid is modified with graphene, and the coloring agent connected to graphene micro-tablets reacts with the color developing agent to produce dying molecules provided with graphene micro-tablets. The graphene micro-tablets with proper size are stably stuck in hair cuticle and are not prone to fall off from hair, so that the dyeing effect is prolonged.

Description

technical field [0001] The invention relates to the technical field of natural plant-based hair dyes, in particular to a graphene-modified hair dye. Background technique [0002] At present, more and more people use commercially available hair dyes to dye their hair into multiple colors such as black, brown, and brown. Wherein the most used black hair dye has been adopted by people for a long time due to its deep color, strong tinting power and fast blackening. However, most of the hair dyes currently on the market contain p-phenylenediamine and quinone compounds, which are toxic, sensitizing, and carcinogenic. The most widely used oxidative hair dye contains more than 20 kinds of chemical components, nine of which can cause cell mutation. If used in large quantities for a long time without paying attention to cleaning, it may cause cancer. Natural plant dyes have received more and more attention from people with their unique safety features, and have become the developmen...

[0003] Patent application number 201310709263.5, CN 103735453 B discloses a preparation method of a health-preserving herbal plant hair dye. In this invention, extracts of various herbal plants are used as hair dyes, although they do not contain chemical hair dye ingredients that are harmful to human health , the use of real fruit extracts such as ginger, black hair grass, black beans, and black sesame seeds has the effect of conditioning hair, but because the principle of coloring is to use herbal pigment molecules with relatively large molecular weights for dyeing, it leads to the penetration of plant dye molecules The force is not strong enough, the dyeing effect is not obvious, which increases the difficulty of coloring

Patent application number 201010207891.X, CN 101869536 B discloses a preparation method of gallic acid hair dye. In this invention, the color reaction between gallic acid extracted from herbal plants and metal ferrous salt is used to achieve the dyeing effect of human hair. Black, has the advantages of deep color, strong tinting power, fast black dyeing, easy to obtain raw materials, non-toxic and harmless, but this kind of hair dye only has the performance of hair dyeing, does not have the corresponding nursing performance, and cannot achieve the effect of hair care and hair care.
