Multi-agent melanin precursor hair dye and utilization method thereof

Abstract

The invention discloses a double-agent melanin precursor hair dye and a three-agent melanin precursor hair dye. The double-agent melanin precursor hair dye comprises an agent A and an agent B; the three-agent melanin precursor hair dye comprises an agent A, an agent B and an agent C; the agent A and the agent C both comprises melanin precursors, common hair dye auxiliaries and water; the common hair dye auxiliaries refer to one or more of a wetting agent, a thickening agent, a surfactant, a moisturizing agent and a pH value regulating agent. By combination of advantages of chemical synthesized hair dye and natural hair dye, compound enzyme liquor in natural edible fungi is extracted, amino acids are subjected to bioconversion to synthesize melanin precursor substances such as hallachrome, 5,6-dyhydroxyindole and 5,6-dyhydroxyindole-2-carboxylic acid, skin irritation and allergization are avoided, high safety is achieved, and natural black hair dyeing effects are kept. In addition, due to various agent type choices, the multi-agent melanin precursor hair dye has a great popularization and application value in the field of hair dye preparation.

Description

technical field [0001] The invention relates to a hair dye prepared by enzyme treatment, in particular to a method of extracting edible fungus enzyme liquid, converting amino acid substrate into natural melanin precursor substance, and preparing it into non-oxidative multi-dosage biological hair dye method. Background technique [0002] At present, with the continuous improvement of people's attention to health, chemically synthesized hair dyes contain carcinogenic and strong allergenic chemical dyeing ingredients (such as phenylenediamines, aminophenols, etc.) and some harmful ingredients (such as hydrogen peroxide) , ammonia, etc.), has been more and more people's attention. For this reason, people try to seek natural harmless, safer hair dyeing materials. For example, plant pigment hair dyes have achieved certain results, but there are still many problems. Such products still cannot avoid adding harmful substances such as phenols and hydrogen peroxide in hair dyes, and ...

AI Technical Summary

Problems solved by technology

For example, plant pigment hair dyes have achieved certain results, but there are still many problems. Such products still cannot avoid adding harmful substances such as phenols and hydrogen peroxide to hair dyes, and lack mature pigment extraction technology.

Known to have the method (patent document CN101164528A) of utilizing plant pigment catechol to prepare natural hair dye at present, but the catechol used wherein is to be extracted from catechin of Chinese medicinal material, and its shortcoming is that the planting scale of Chinese medicinal material is limited, and the pigment extraction cost Relatively high; Also have the report to utilize the catechol oxidase in the filamentous fungus cell of expressing mold to oxidize dopa and its derivatives by genetic engineering technology, convert it into the method of melanin precursor (patent document CN101914585A ), but the mold itself will produce some toxic and harmful substances, and the production process will cause environmental pollution. At the same time, there are disadvantages such as high cost, long time consumption, unstable performance, and inability to apply in large quantities.

In the prior art, there is also a method of using the enzyme liquid extracted from the Bacillus fermentation liquid to catalyze the substrate to produce melanin precursors, but the safety and non-toxic side effects of the product cannot be guaranteed, and the pollution in the fermentation process will also affect the product quality.
