Introduction
The detergent industry is one of the important application fields of enzyme preparations. GB/T 42239 "Enzyme Preparations for Detergents" is formulated, which is for domestic detergents
The product industry regulates the market segment of enzyme-containing cleaning products, guides companies in the industry to innovate and develop new products, and prevents unscrupulous companies from cheating consumption
It is of great significance to promote the rapid and healthy development of the detergent industry.
GB/T 42239 "Enzyme preparations for washing" is proposed to be composed of the following two parts.
--- Part 1.Alkaline protease, the purpose is to establish the classification and technical requirements of alkaline protease for washing;
--- Part 2.Lipase, the purpose is to establish the classification and technical requirements of lipase for washing.
