Plant hair dye by taking ginger extract as penetrating agent

Abstract

The invention discloses an application of a ginger extract used as a penetrating agent in a plant hair dye. Two dyes are prepared and matched in use, wherein the No.1 dye is prepared in such a way that the ginger extract is used as the penetrating agent, copperas is used as a dye, and thickening agent and deionized water are added; and the No.2 dye uses gardenia yellow pigment or rhizoma coptidis, giant knotweed, nutgall, pomegranate rind, Jamaica wood, red sorghum pigment, rutin and lawsonia pollen as a dye macromolecule. The two dyes are respectively prepared and stored, and used together during hair dyeing. The invention does not contain chemical dye, chemical penetrating agent and hydrogen peroxide, does not damage hair quality and keeps color for more than 45 days.

Description

Technical field: [0001] The invention relates to a plant hair dye, in particular to a plant hair dye using ginger extract as a penetrating agent, which belongs to the hairdressing product in the cosmetics industry, that is, the hair dye. technical background: [0002] At present, the vast majority of hair dyes on the market are made of chemically synthesized p-phenylenediamine and other compounds with benzene rings. A large number of studies and reports have proved that p-phenylenediamine and other compounds with benzene rings are harmful to the skin It is irritating and allergenic, and is easily absorbed by the skin, accumulates in the body to cause poisoning, and can induce various cancers. Rats were injected subcutaneously with p-phenylenediamine, the minimum lethal dose was 600 mg / kg body weight; rabbit oral minimum lethal dose was 250 mg / kg body weight. In addition, studies have proved that these substances have mutagenic toxic side effects on the human body, causing d...

Problems solved by technology

In addition, studies have proved that these substances have mutagenic toxic side effects on the human body, causing damage to the scalp, making the hair lose its luster, darken the color, and make the hair brittle and easy to break.

Therefore, the safety of hair dye products has attracted more and more attention. In addition, there are also some hair dyes on the market that use plant roots, stems, and leaf grinding powder or extracts as dyes, but because the molecules of plant dyes are too large , it is difficult to quickly enter the hair scales, it is not easy to color, even if it is attached to the color, it is easy to fade, the adhesion is not strong, the dye molecules only adhere to the outer layer of the hair, and cannot penetrate into the interior to achieve firm coloring
