Problems solved by technology

In this process, human hair will cause serious damage when it is treated with chlorination and alkaline bleaching, and the chlorination treatment will have some residual effective chlorine, and a large amount of metal ions will be used in the medium treatment, and the metal ions will also be damaged. There are some residues, which do not meet the requirements of health and environmental protection

Embodiment 1

[0021] Step 1. Weigh 1g of human hair, wash it thoroughly with water, and dry it naturally.

[0022] Step 2. Put the dried human hair in step 1 into 50ml of emulsifier MOA-15 ​​solution (solution concentration: 5g / L) to degrease for 90 minutes. After degreasing, fully wash with water and dry naturally.

[0023] Step 3, immerse the hair prepared in step 2 in 30ml of crude laccase solution (solution concentration is 5g / L) to carry out laccase-mediator system oxidation pretreatment on degreasing hair, under the temperature condition of 50 ℃ , stirred and reacted for 120min, and after the pretreatment was completed, it was fully washed with water and dried naturally.

[0024] Step 4, immerse the hair processed in step 3 in the oxygen bleaching liquid (solution concentration is 10g / L) of 50ml, oxidant is the mixture of hydrogen peroxide and potassium persulfate compound salt (the quality of hydrogen peroxide and potassium persulfate compound salt The ratio is 5:5), and 2g / L of non...

Embodiment 2

[0027] Step 1. Weigh 2g of human hair, wash it thoroughly with water, and dry it naturally.

[0028] Step 2. Put the dried human hair in step 1 into 80ml of emulsifier MOA-20 solution (solution concentration: 3g / L) to degrease for 100min. After degreasing, fully wash with water and dry naturally.

[0029] Step 3, immerse the hair prepared in step 2 in 50ml of crude laccase solution (solution concentration is 3g / L) to carry out laccase-mediator system oxidation pretreatment on degreasing hair, under the temperature condition of 40 ℃ , stirred and reacted for 180min, and after the pretreatment was completed, it was fully washed with water and dried naturally.

[0030] Step 4, immerse the hair processed in step 3 in the oxygen bleaching liquid (solution concentration is 5g / L) of 60ml, oxidizing agent is the mixture of hydrogen peroxide and potassium hydrogen persulfate compound salt (the quality of hydrogen peroxide and potassium hydrogen persulfate compound salt The ratio is 2:...

Embodiment 3

[0033] Step 1. Weigh 5g of human hair, wash it thoroughly with water, and dry it naturally.

[0034] Step 2. Put the dried human hair in step 1 into 200ml of emulsifier MOA-9 solution (solution concentration: 8g / L) to degrease for 120 minutes. After degreasing, fully wash with water and dry naturally.

[0035] Step 3, immerse the hair prepared in step 2 in 100ml of crude laccase solution (solution concentration is 8g / L) to carry out laccase-mediator system oxidation pretreatment on degreasing hair, under the temperature condition of 40 ℃ , stirred and reacted for 150min, and after the pretreatment was completed, it was fully washed with water and dried naturally.

[0036] Step 4, immerse the hair processed in step 3 in the oxygen bleaching liquid (solution concentration is 8g / L) of 100ml, oxidant is the mixture of hydrogen peroxide and potassium hydrogen persulfate compound salt (the quality of hydrogen peroxide and potassium hydrogen persulfate compound salt The ratio is 8:2...

Abstract

The invention discloses a novel hair bleaching method. The whitening degree of bleached human hair obtained by the method is high, and pretreatment with laccase allows consumption of various chemicalsto be much less than that of a conventional process, treatment steps harmful to human bodies are reduced, and chemical residue is low. As the consumption of various chemicals is low, a problem that bleaching is nonuniform due to a high number of foams generated in traditional bleaching is effectively controlled, and a uniform bleaching effect is obtained. The method can be used for dyeing bleached hair, increasing the dyeing type of hair, and achieving colorful wigs.

Description

technical field [0001] The invention belongs to the field of hair bleaching, and in particular relates to a hair bleaching method combining laccase pretreatment, oxygen bleaching and reduction rebleaching. Background technique [0002] The pigment on human hair mainly exists in the form of melanin, which is widely present in the human body as a prosthetic group of protein, and is divided into eumelanin and dark melanin. The former is generally black, yellow and brown, and the latter is usually red and reddish brown. , the content and ratio of the two determine the color of the hair. Eumelanin and dark melanin exist in discrete granules, which can appear in the cortex and scales. The pigment granules have special structure (mitochondrion) and chemical composition (envelope and carrier membrane of phospholipid-sterol bilayer), with special Strong chemical resistance. [0003] The traditional black human hair bleaching process is: washing and degreasing→chlorination treatment...
