Description

Technical field

[0001] The invention involves a laundry solution, especially for a protease super concentrated laundry solution and its preparation method, which is a daily chemical field. Background technique

[0002] With the continuous development of modern society, household detergents have also been developed from soap and laundry powder, which slowly developed to today's laundry solution. The new generation of laundry liquid has gradually been accepted by domestic consumers. There are many types of types in the market.Laundry products.

[0003] Although many laundry liquids on the market have various functions, there are still shortcomings.Throughout the laundry liquid on the market, most of the conventional products make these laundry liquids on some stubborn stains, such as blood stains, protein stains, and fat stains that cannot be completely removed or removed.On the other hand, most of the laundry liquids on the market currently are ordinary, with few concentrated type...
