Abstract

The invention discloses a dendritic macromolecule catalytic hair dyeing agent and preparation and use methods thereof, wherein the dendritic macromolecule catalytic hair dyeing agent comprises an agent A and an agent B. The agent A consists of the following components: 5,6-dihydroxy indole, cetostearyl alcohol, oleic acid, propylene glycol, isopropanol, sodium dodecyl sulfonate, a polyethylenediamine dendritic polymer, ammonia water and water. The agent B consists of the following components: hydrogen peroxide, cetostearyl alcohol, oleic acid, propylene glycol, isopropanol, sodium dodecyl sulfonate, phosphoric acid and the like. The preparation method comprises the steps: firstly, preparing the agent A, and then preparing the agent B. The use method comprises the steps: mixing the agent Aand the agent B in a proportion of 1:1, stirring evenly, then applying to hair, and 30 min later, cleaning the hair. The 5,6-dihydroxyindole in the hair dyeing agent is not easy to oxidize and is easyto preserve in air, has quite obvious dyeing effect is and can enter the interior of hair medulla of hair and the hair dyeing agent is washed and is not easy to fade after dyeing.

Description

technical field [0001] The invention relates to the technical field of hair dyeing, in particular to a dendritic macromolecule catalytic hair dye and a preparation and use method thereof. Background technique [0002] Hair dye is a kind of cosmetics for dyeing hair. Chinese people belong to the yellow race, and it is more beautiful to dye white hair black, so black hair dye is very important. [0003] Hair dyes generally contain p-phenylenediamine, a carcinogen. Studies have shown that hair is composed of epidermal scale layer, cortex layer, and medulla layer. The epidermal scale layer is the outermost layer of hair, which is usually translucent or colorless. The natural hair color is revealed; the cortex layer accounts for 80% of the hair, and the natural pigment synthesized by the human body, that is, melanin, is deposited here. Due to the difference in the amount of melanin deposition, different hair colors appear; the medulla layer is located in the center of the hair an...
