Plant hair dye with isomerized C10 ethoxylate as penetrating agent and its preparation method

Abstract

The invention discloses a plant hair dye with isomerized C10 ethoxylate as a penetrating agent. Employing a plant color coupler, the hair dye is characterized in that the penetrating agent promoting the penetration of the plant color coupler into dyed hair is isomerized C10 ethoxylate. The plant color coupler is formed by subjecting a metal salt and plant extract to a color development reaction, and also can be plant henna powder. And the plant extract can be sappan wood extract or Chinese gall extract. In the plant hair dye with isomerized C10 ethoxylate as the penetrating agent in the invention, the employed raw materials are classified into two components: agent A and agent B. The agent A is composed of 0.5-5 parts of a metal salt, 0.02-0.25 part of isomerized C10 ethoxylate, and 10 parts of deionized water by weight, with a pH value of 0.02-8. And the agent B is composed by 0.01-5 parts of silicone oil and 10-100 parts of plant extract by weight. Containing no aniline compound and hydrogen peroxide, the plant hair dye of the invention does not damage hair, and can be colorfast for over two months compared with ordinary plant hair dyes, and is characterized by better dyeing effect and longer effectiveness.

Description

technical field [0001] The invention relates to a plant hair dye in the technical field of cosmetics industry and a preparation method thereof, in particular to a plant hair dye using isomeric C10 ethoxylate as a penetrating agent and a preparation method thereof. Background technique [0002] Hair coloring products currently on the market have various raw material components according to different types in the market, and there are as many as a dozen chemical components: p-phenylenediamine, p-toluenediamine, p-aminophenol, m-aminophenol, etc. But almost all chemical oxidation hair dyes contain p-phenylenediamines, because they are the most effective ingredients in hair dyes. Because synthetic hair dyes are mutagenic and cancer-inducing to human health, as early as the 1990s, it was suggested that hair dyes may cause cancer. Although there are many controversies, it is agreed that hair dyes containing aniline substances have potential carcinogenicity Dangerous, long-term us...

Problems solved by technology

[0016] For example, the Chinese invention patent CN 1418612 introduces a kind of active hair coloring agent prepared by compounding wild plants, but the molecule of traditional Chinese medicine is relatively large, and it is difficult to enter the hair cuticle, so the coloring effect of this hair dyeing agent is poor, and it is not a permanent hair dyeing agent.

Also have Chinese patent CN1698575A, Chinese patent CN 101229110A to introduce the reddish-brown Chinese medicine dye hair dye that takes clove as penetrating agent, make Chinese medicine dye enter in the hair flake by Chinese medicine clove as penetrating agent, can reach permanent hair dye level, but eugenol The surface activity is limited, and the formula of various plant raw materials increases the difficulty of raw material preparation, and the production and process of the product are more complicated
