Abstract

The invention provides plant hair dye of modified graphene aerogel and a preparation method of the plant hair dye. The plant hair dye comprises the following steps that graphene aerogel powder is dissolved into an N,N-dimethy formamide solution,the mixture is subjected to ultrasonic oscillation and mechanical stirring,and then a graphene aerogel colloid solution is obtained; tetraethyl orthosilicate is added into the graphene aerogel colloid solution,ammonium hydroxide is dropwise added under high-speed stirring,heating stirring continues,and then a graphene aerogel solution of modified silicon dioxide is obtained; the graphene aerogel solution of modified silicon dioxide is filtered,solvent is removed through sufficient drying,and the graphene aerogel of modified silicon dioxide is obtained; the graphene aerogel of modified silicon dioxide is dispersed in water,plant dye active components are added,sufficient stirring,standing and concentrating are performed,and finally the product isobtained. With the graphene aerogel being a carrier of the hair dye,a rich porous structure and a silicon dioxide layer contained on the surface can obviously improve the stability of the plant active dye and increase the content of the plant active dye,and therefore the hair-dyeing effect of the hair dye is promoted.

Description

technical field [0001] The invention belongs to the technical field of daily cosmetics, and in particular relates to a plant hair dye modified by graphene airgel and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, hair dye has gradually entered the homes of ordinary people as a daily beauty cosmetic for changing hair color. It can not only improve the effect of gray hair, but also give hair color colorfulness. In recent years, the development of hair dyes in the field of cosmetics has been very active. Traditional hair dyes are mostly inorganic mineral hair dyes and chemically synthesized hair dyes. Inorganic mineral hair dyes contain heavy metals such as Pb, Ni, and Co, which are easily compatible with certain Specific enzymes combine to form complexes, which directly interfere with and destroy the normal physiological activity of enzymes, leading to various toxic diseases, such as birth deformities, organ damag...
