Problems solved by technology

Most of them are fungal laccases, but fungal laccases generally catalyze pH requirements under acidic conditions, and the optimum temperature is not high
The dyeing that directly acts on the human hair requires a certain temperature, neither too high nor too low, to make the human body comfortable, and the pH of the hair dyeing needs to be opened under neutral or alkaline conditions to reach the hair cortex. Dyeing effect, so the general fungal laccase can not meet the dyeing needs

Abstract

The invention relates to a dyeing composition which contains bacterial laccase Lac15 from marine microorganisms and is applied to a keratin fibre, particularly human hair. The composition contains the bacterial laccase Lac15, at least one oxidizing dye and at least one surfactant. The invention also relates to an application method in dyeing of the keratin fibre, particularly human hair. The composition disclosed by the invention can be prepared into a stand-by preparation under the existence of at least one oxidizing dye, so as to achieve an even dyeing effect, good strength and good chromaticity. Serious degradation is not caused, decoloration of the keratin fibre is not caused, and the keratin fibre dyeing composition is small in selectivity, and can well tolerate various stimulations possibly generated on the hair.

Description

technical field [0001] The present invention relates to a dye composition for keratin fibers, in particular human hair, containing marine bacterial laccase Lac15 and a dyeing method thereof. Background technique [0002] With the improvement of living standards, people have paid more and more attention to the beauty of the appearance. Some gray hairs caused by factors such as genetics, metabolism, and nutrition have seriously affected the aesthetics and people's requirements for appearance. Hair dyeing is used to change its own color. On the other hand, for the pursuit of individuality and other reasons, it is necessary to change one's single hair color, and hair dyeing is also used to modify and achieve the goal. [0003] Hair dyeing is a chemical process that cannot be seen with the eyes. Oxidative dyes and oxidant particles soften and expand the hair through alkaline conditions, penetrate through the epidermis to the middle cortex, and when these particles organize into a...
