preparation example Construction

[0040] Preferably, the POSS linear polymer preparation method of the pyrogallic acid surface functionalization comprises:

[0041] Step 1, mixing acetone, phosphorus trichloride, and pyrogallic acid, stirring in an ice-water bath for 5-8 hours to obtain acetone-protected gallic acid;

[0042] Step 2, reacting the product of the previous step with 2-aminoethanethiol under the action of a catalyst to obtain the pyrogallic acid functionalized monomer protected by acetone;

[0043] Step 3, using T8 type POSS as the starting monomer to synthesize hexaethylenedicarboxy POSS and hexaethylenedihydroxy POSS, and polymerize to generate POSS linear polymer;

[0044] Step 4. After reacting the acetone-protected pyrogallic acid functionalized monomer with the POSS linear polymer, adding acetic acid to remove the acetone protection to obtain the POSS linear polymer with pyrogallic acid surface functionalized.

[0045] Preferably, the catalyst in step 2 is potassium iodide, and the conditio...

Abstract

The invention discloses a plant polyphenol polymer-based composite hair dye. The plant polyphenol polymer-based composite hair dye comprises an agent A and an agent B, wherein the mass ratio of the agent A to the agent B is 1:1; and the agent B comprises the following components: 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 a pyrogallic acid surface functionalized POSS linear polymer can effectively prevent oxidative deterioration of 5,6-dihydroxyindole, so that the hair dyeing efficiency is improved; the polymer is high in adhesion and relatively large in molecule, can be better attached to an epidermal scale layer, and seals synthesized melanin in a cortical layer to ensure that the hair dyeing effect is stable and washable; and the pyrogallic acid surface functionalizedPOSS linear polymer is non-irritating to the skin.

Description

technical field [0001] The invention relates to the technical field of hair dyes, in particular to a composite hair dye based on plant polyphenol polymers. 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, the existing hair dyes generally contain carcinogenic chemical ingredients (anilines) and harmful ingredients, which are contrary to the principl...
