Abstract

The invention discloses a hair dye containing polysaccharide natural polyphenols. The hair dye comprises an agent A and an agent B in a mass ratio of 1: 1, wherein the agent B comprises the followingcomponents: 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 acid and the balance of deionized water; a large number of phenolic hydroxyl groups in neomycin sulfate modified eriodictyol-7-O-glucoside can effectively prevent oxidative deterioration of 5, 6-dihydroxyindole, sothat the hair dyeing efficiency is improved; the neomycin sulfate modified eriodictyol-7-O-glucoside has ultraviolet absorptivity and can protect the skin from being injured by ultraviolet rays; thehair dye has no irritating to skin; and due to the introduction of neomycin sulfate, the dyed hair can release antibacterial drugs under specific conditions, and the hair dye has a certain antibacterial effect and does not affect the hair dyeing effect at the same time.

Description

technical field [0001] The invention relates to the technical field of hair dyes, in particular to a hair dye containing polysaccharide natural polyphenols. 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 of h...
