Problems solved by technology

When a single enzyme is used for treatment, due to the specificity of the enzyme, it will not be able to effectively degrade the peptide bonds of various proteins in the hair scale layer, making it difficult for ferrous ions and citric acid to enter the fiber during the pre-media treatment in the later stage. It also hinders the penetration of hydrogen peroxide during the bleaching process
However, the descaling treatment carried out after compounding with several enzymes results in poor descaling effect due to the different optimal process conditions (such as pH value, temperature, time, etc.) of various enzymes in the use process, resulting in Prolongation of bleaching time and impact on fiber strength properties; in addition, it will lead to a longer time for descaling treatment (>4h), thereby increasing production costs

Abstract

The invention belongs to the field of human hair product processing, and particularly relates to a bio-enzyme composite desquamation technology for human hair fiber. The bio-enzyme composite desquamation technology comprises a step of performing desquamation treatment on the human hair fiber sequentially through protease A and protease B, wherein the protease A is one of bacillus subtilis protease, bacillus licheniformis protease, bacillus cereus protease, ficin and chymotrypsin; and the protease B is one of actinomycetes protease, aspergillus oryzae, aspergillus niger, trypsin, endopeptidase, hemocoagulase, papain and bromelain. The technology provided by the invention is simple and easy to implement.

Description

technical field [0001] The invention belongs to the processing field of human hair products, and in particular relates to a bio-enzyme composite descaling process of human hair fibers. Background technique [0002] In the production process of human hair products, it is necessary to first destroy the surface scale layer-the peeling process, and then destroy the natural melanin in human hair by means of oxidation or reduction, and then produce human hair products with various colors and properties. However, the basic component of the human hair scale layer is hard keratin composed of various natural amino acids, which has high stability, good elasticity, and small expansion. It itself plays a very important role in protecting the cortical layer and melanin inside the human hair. For this reason, most of the traditional human hair products industries use chlorine-containing reagents to first descale human hair, that is, use acid descaling to allow bleaching agents to penetrate...
