Abstract

The invention provides gallic acid hair dyes and a preparation method and an application thereof. The hair dyes comprises the following components according to mass percent: 2.0-12.0% of gallic acid, 11.0-13.3% of auxiliary agent, 16.0-20.0% of cosolvent, 2.0-13.0% of metal ferrite and 43-66.8% of distilled water. The preparation method comprises the following steps: a. completing dissolving each component in the auxiliary agent except alkali neutralizer and cosolvent and distilled water according to the content and dividing into two equal parts, adding gallic acid to one part to form dye, and adding metal ferrite to form metal ionic agent; and b. regulating pH value to 7-9 with the alkali neutralizer after two parts of mixture are completely dissolved, and respectively packaging the obtained dye and metal ionic agent. The gallic acid hair dye is used for black-dyeing of human hair. The invention is characterized by easily obtained raw materials, simple extraction process, non-toxity and harmlessness, and safe and reliable use, and is beneficial for environmental protection.

Description

【Technical field】 [0001] The invention relates to a hair dye for human hair, in particular to a gallic acid hair dye prepared from plant extract gallic acid, a preparation method and application thereof. 【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. Among them, 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. Yet as people know, existing hair dyes are all prepared with chemically synthesized dyes and pigments as raw materials, and along with people's emphasis on health, the hair dyes prepared with chemically synthesized dyes and pigments are because of their carcinogenic chemical composition ( Aniline dyes,) and harmful health ingredients (strong oxygen agent hydrogen peroxide, benzoyl peroxide, etc.) have aroused people's attention to its safety. For this reas...
