Description

Melanin hair dye and using method thereof
Technical Field
The invention belongs to the field of cosmetics, and particularly relates to a melanin hair dye and a using method thereof.
Background
Hair dye refers to cosmetic capable of changing hair color and having special application. The hair dyes that have been most used for a long time are permanent and semi-permanent hair dyes. However, as an oxidation dye which is a main component of the oxidation hair dye, a conventional permanent hair dye is also called an oxidation hair dye. The specific dyeing mechanism of the hair dye is that oxidation dye intermediate with low relative molecular mass and other components penetrate into the hair, undergo oxidation polymerization in the hair to generate macromolecular dye and are locked in the hair. Oxidative hair dyes are mostly composed of 3 reactive compounds, namely, dye intermediates, couplers (also called couplers) and oxidizing agents, and particularly p-phenylenediamine has been found to be an allergic substance which causes allergic dermatitis and is banned by some european countries. Recent scientific research also shows that phenylenediamine and some derivatives thereof have accumulative property, rust degeneration and mutation property, and can cause keratitis, nephritis, leukemia and the like. Meanwhile, most of the permanent hair dyes in the current market are two-agent hair dyes, and the permanent hair dyes need to be blended before hair dyeing, so that the hair dyeing process is complicated.
The plant type hair dye uses one plant extract or a mixture of a plurality of plants as a raw material of the hair dye, wherein the mixture of the plurality of plant extracts is used for preparing most of the hair dyes, the extraction process is complicated, and the plurality of hair dyes are prepared only primarily and no products are produced. It is reported that the domestic health department has not approved the plant hair dyes made of plant extracts completely, and most of the commercially available 'pure plant hair dyes' are gimmicks made of some ingredients containing plants, wherein some chemical ingredients such as PPD are mixed.
Melanin is divided into synthetic melanin and natural melanin, and natural melanin refers to a natural biological pigment extracted from plants, animals and microorganisms, and has a wide variety of sources, and is the most extensive pigment in the known biological pigments at present. Melanin from natural sources is insoluble in acid and water, but has greater solubility in lye where p H is greater than 8.5. The melanin is insoluble in ethanol, methanol, acetone, ether and other common organic solvents, the chelation capacity of the melanin to the metal ions with the valence of 2 and 3 is very strong, and at present, a plurality of black hair dyes achieve the purpose of coloring by utilizing the chelation of the melanin and the metal ions.
The existing hair dye has unstable dyeing color and is easy to have the problems of hair color change or fading in the hair washing process.
Disclosure of Invention
The invention mainly aims to provide a melanin hair dye, which is a novel three-agent type hair dye prepared by taking melanin naturally produced by culturing melanocytes as a raw material of the hair dye. Under certain conditions, melanin can be complexed with metal ions to form a macromolecular compound, but the diameter of the melanin molecule is large, so that the melanin molecule is not beneficial to permeating into hair. Therefore, the agent A is used as a hair pretreatment agent, and the penetrant is used to open the disulfide bonds in the hair, thereby facilitating the penetration of the following metal ions and coloring agents into the hair. The metal ions in the agent B enter human hair and are firstly complexed with amino acid in the hair, the agent C enters the hair and is complexed with the metal ions to form macromolecular melanin, hair scales are closed, and the pigment is locked inside a hair rod.
