Abstract

The invention discloses a hair dye containing a plant polyphenol functional material. The hair dye comprises an agent A and an agent B, the mass ratio of the agent A to the agent B is 1: 1, and the agent B is composed of 18-26% of hydrogen peroxide, 8-15% of oleyl alcohol, 8-15% of oleic acid, 8-15% of propylene glycol, 8-15% of isopropanol, 1-5% of sodium dodecyl sulfate, 1-5% of phosphoric acidand the balance deionized water. A large amount of phenolic hydroxyl groups in the gallic acid functionalized POSS nanoparticles protected by the mercapto-terminated acetone can effectively prevent oxidative deterioration of 5, 6-dihydroxyindole, so that the hair dyeing efficiency is improved; meanwhile, adhesion is high, molecules are large, the material can be well attached to an epidermal scalelayer, synthesized melanin is sealed in a cortex layer, and it is guaranteed that the hair dyeing effect is stable and resistant to washing; the mercapto-terminated acetone protected gallic acid functionalized POSS nanoparticles can also improve the mechanical properties of the hair.

Description

technical field [0001] The invention relates to the technical field of hair dyes, in particular to a hair dye containing plant polyphenol functional materials. Background technique [0002] Hair dyeing is one of the most common means for people to change their image. As a cosmetic with the effect of changing hair color, hair dye has begun to become a daily necessity for more and more people. Human hair consists of three parts: the epidermal scale layer, the cortex layer and the medulla layer. The outermost layer is the translucent or colorless epidermal scale layer; the cortex layer is the part where the body synthesizes melanin, and the inner layer is the medulla layer. Among them, the amount of melanin deposition in the cortical layer determines the difference in hair color, and is also the core part of the dyeing process. However, existing hair dyes generally contain carcinogenic chemical ingredients and harmful health ingredients, which are contrary to the principles o...
