Abstract

The invention discloses a graphene hydrogel hair dye, a preparation method and an application method thereof. The preparation method of described graphene hydrogel hair dye comprises: respectively provide graphene material dispersion liquid, genipin solution; Make the homogeneous mixing system that comprises graphene material dispersion liquid, biodispersant, genipin solution and essence stir 5-30 minutes, and then ultrasonic for 5-30 minutes to obtain the graphene hydrogel hair dye. The invention utilizes the principle of strong physical adsorption of large-scale graphene materials, which can be firmly adsorbed on hair. At the same time, genipin is a biological cross-linking agent, which can cross-link and thicken graphene materials, and further strengthen graphene materials. Strong adsorption to hair, good hair dyeing effect, resistant to shampoo washing, so that the color of dyed hair can last 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. [0003] With the increasing emphasis on environmental prot...
