Graphene hydrogel hair dye as well as preparation method and use method thereof

Abstract

The invention discloses a graphene hydrogel hair dye as well as a preparation method and a use method thereof. The preparation method of the graphene hydrogel hair dye comprises the following steps ofproviding a graphene material dispersion liquid and a genipin solution separately; stirring a uniform mixing system containing the graphene material dispersion liquid, a biological dispersant, the genipin solution and essence for 5-30 minutes, and then performing ultrasonic treatment for 5-30 min to obtain the graphene hydrogel hair dye. According to the hair dye, the principle of strong physicaladsorption of the large-size graphene material is utilized, so that the graphene hair dye can be firmly adsorbed on hair; and meanwhile, the genipin is a biological cross-linking agent, so that the graphene material can be cross-linked and thickened, the adsorption strength of the graphene material and the hair is further enhanced, the hair dyeing effect is good, the hair dye is resistant to hairwashing, and the holding time of the hair dyeing color is longer.

Description

technical field

[0001] The invention relates to a green and safe hair dye, in particular to a graphene hydrogel hair dye, a preparation method and a use method thereof. Background technique

[0002] As early as 150 BC, there were records of using natural plant hair dyes in ancient China and Egypt. With the progress of the times, the color and effect of natural plant hair dyes cannot meet the hair dyeing needs of modern people. Therefore, metal salt hair dyes and chemically synthesized hair dyes have appeared. Metal salt hair dyes contain heavy metals such as Pb, Co, and Ni. It will damage the kidney, brain and central nervous system, leading to deformities and other diseases; chemically synthesized hair dyes contain aromatic amines, aminophenols, p-phenylenediamine (PPD) and other components, which have certain toxicity and sensitization. It needs to open the cuticle of the hair, which can damage the hair quality.
