Melanin precursor substance hair dye and using method thereof

Abstract

The invention discloses a melanin precursor substance hair dye. The melanin precursor substance hair dye consists of a melanin precursor, a common hair dye adjuvant and water, wherein the melanin precursor includes dopachrome, 5,6-dihydroxyindole and 5,6-dihydroxyindole-2-carboxylic acid; the melanin precursor accounts for 0.01-5% of the hair dye in percentage by weight; and the common hair dye adjuvant includes one or more of a wetting penetrating agent, a thickening agent, a surfactant, a moisturizer and a pH value regulating agent. The hair dye disclosed by the invention combines the advantages of a chemically synthetic hair dye and a natural hair dye; by extracting complex enzyme liquid in natural edible fungi, such melanin precursor substances as the dopachrome, the 5,6-dihydroxyindole, the 5,6-dihydroxyindole-2-carboxylic acid and the like are synthesized through bio-conversion by virtue of amino acid, so that the hair dye is free from irritation and allergy to skin, high in safety and capable of keeping a natural black hair dyeing effect; and the hair dye has huge popularization and application values in the field of the preparation of hair dyes.

Description

technical field [0001] The invention relates to a hair dye prepared by enzyme treatment, in particular to a method for extracting edible fungus enzyme liquid, converting an amino acid substrate into a natural melanin precursor, and preparing it into a non-oxidative biological hair dye. 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 lack mature pigment ext...

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.
