However, there are still problems with 5,6-dihydroxyindole melanin hair dye: although the 5,6-dihydroxyindole intermediate is active enough, it is still difficult to naturally oxidize and blacken the hair in a limited time in the air, so that Not good for coloring

Abstract

The invention discloses a hair dye for catalyzing melanin polymerization by perfumed soap, a preparation method and a use method of hair dye. The hair dye comprises a first agent and a second agent, the first agent is prepared from the following components in percentage by mass: 1%-3% of 5, 6-dihydroxyindole, 4%-8% of C16-18 alcohol, 12%-16 percent 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%-0.5% of ascorbic acid ethyl ether, 0.2%-2% of polydimethylsiloxane, 0.05%-0.1 % of guar gum hydroxypropyl trimethyl ammonium chloride, a proper amount of ethanolamine and the balance of water; the second agent is a soap base and comprises the following components: 20-30% of olive oil, 20-30% of coconut oil, 5-20% of sodium hydroxide and the balance of water. The hair dye is fast in coloring and good in coloring effect; in addition, the invention is milder and safer and is beneficial to improving hair flexibility.

Description

technical field [0001] The invention belongs to the field of daily chemicals, and in particular relates to a soap-catalyzed hair dye for melanin polymerization, a preparation method and an application 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 the pressure 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 more and more common to dye gray hair black. Since the hair scales are only 1-2 nanometers in size, many melanins 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 thro...
