Problems solved by technology

The disadvantages of this type of hair dyes are 1) high toxicity and safety concerns; 2) double agents, to be mixed before use; 3) ammonium hydroxide pungent smell; 4) hydrogen peroxide that consumers do not like
[0007] 5,6-dihydroxyindole has been researched as a hair dye for more than 50 years. The products currently on the market include Kao’s Re-rise and Henkel’s Re-Nature, but this product is based on hair dye and airborne Oxygen slowly oxidizes and changes color to produce hair dyeing effect, so the hair dyeing speed is slow. For natural gray hair, after using it for more than 5 times, there are still gray hairs that are not fully covered.
[0011] US Patent US 5135 544 discloses a method of using periodic acid oxidizing agent, but this strong oxidizing agent is not allowed to be used in cosmetics in China now

Embodiment 1

[0068] Formulation of composition A--ointment

[0069] 5,6-Dihydroxyindole 1.0％ Vitamin C 0.3％ Sulfite 0.1％ Ethanol 10％ Seppic-305 5％ Monoethanolamine Right amount, adjust PH to 9.5 water Margin, add to 100%

[0070] Formulation of Composition B--Conditioning Shampoo

[0071]

[0072] Use undamaged natural human hair, with white hair accounting for 100% of the tress, apply composition A evenly, leave on for 5 minutes, rinse with clean water, dry the tress until no water runs, then apply composition B evenly, rub Knead until foamy, leave on for 5 minutes and rinse off. The white hair is complemented to black, and the black hair becomes more jet black and shiny. Apply it three times in a row to completely cover white and black.

Embodiment 2

[0074] Formulation of Composition A--Spray

Abstract

A keratin fiber dyeing composition and method comprising a composition A comprising a melanin precursor, such as 5, 6-dihydroxyindole or 5, 6-dihydroxyindoline, and a composition B comprising a salt of a transition metal ion, such as a bivalent copper ion, a bivalent manganese ion, a bivalent iron ion, and a chloride ion and TRIS. The two compositions are used successively, and a cleaning process can be performed between the composition A and the composition B. According to the composition and the hair dyeing method, the coloring time is short, and the color is closer to the natural hair color of a black hair variety.

Description

Technical field: [0001] The present invention relates to keratin fiber dyeing compositions and dyeing methods. In particular, the present invention relates to compositions for dyeing keratin fibers, especially human keratin fiber hair, using 5,6-dihydroxyindole, or 5,6-dihydroxyindoline melanin precursors and Dyeing method. Background technique: [0002] Oxidative dyeing of keratin fibers is one of the most widely used dyeing methods. In the traditional chemical hair dyeing process, chemical oxidants catalyze the oxidation reaction of hair coloring precursors for dyeing. In this method, an oxidative hair coloring precursor is used in combination with an oxidizing agent. Oxidative hair coloring precursors are generally small molecules capable of diffusing into the hair. Most of these precursors contain groups such as amino groups, and the dyeing components in the most commonly used chemical hair dyes are o- or p-phenylenediamine, o- or p-aminophenol, and heterocyclic comp...
