Melanin bionic hair dye containing aspergillus fermentation product and preparation method of melanin bionic hair dye

Abstract

The invention discloses a melanin bionic hair dye containing an aspergillus fermentation product and a preparation method of the melanin bionic hair dye, the melanin bionic hair dye is in a dosage form, and the melanin bionic hair dye comprises the following components: 2-6% of the aspergillus fermentation product; 1%-3% of 2, 5, 6-dihydroxy indole; 4% to 8% of C16-18 alcohol; 12%-16% of olive oil; 0.5%-2% of PEG-7 olive oil; 2%-8% of propylene glycol; 1%-6% of cysteine; 0.1%-0.2% of sodium sulfite; 0.1% to 0.5% of ascorbic acid ethyl ether; 0.2% to 2% of polydimethylsiloxane; 0.05% to 0.1% of guar gum hydroxypropyl trimethyl ammonium chloride; 4%-10% of ethanolamine; and the balance water. According to the method disclosed by the invention, the oxidation speed of 5, 6-dihydroxyindole outside hair is inhibited by utilizing the aspergillus fermentation product, so that more 5, 6-dihydroxyindole enters hair cuticles, and a faster and better coloring effect is obtained.

Description

technical field [0001] The invention belongs to the field of daily chemicals, in particular to a melanin biomimetic hair dye containing aspergillus fermentation product and a preparation method thereof. Background technique [0002] The color of human hair is determined by the number of melanin particles in the hair cortex. With age and stress caused by fast-paced work and life, the production of melanin particles will gradually decrease, and black hair will gradually become gray, and it is becoming more and more common to dye gray hair black. Because the size of the hair scales is only 1-2 nanometers, many melanin cannot enter the hair. At present, the basic idea of ​​permanent hair dye is: first use small molecules to enter the hair cuticle, and then use hydrogen peroxide, carbamide peroxide and other initiators to initiate the polymerization of small molecules to obtain a large molecular black substance, because the large molecular black substance cannot pass through the...

Problems solved by technology

But there is still a problem with 5,6-dihydroxyindole melanin hair dye: the oxidation speed of 5,6-dihydroxyindole does not match the speed of its entry into the hair cuticle

Specifically, in order to limit the hair dyeing time within a certain time range, the oxidation rate of 5,6-dihydroxyindole is further increased, which makes some intermediate small molecules polymerize into large molecules before they can enter the hair cuticle. And can not enter the cuticle, resulting in the color of the hair dye is not obvious
