Problems solved by technology

[0003] Although many laundry detergents on the market have various functions, there are still deficiencies
Looking at the laundry detergents on the market, most of them are conventional products, which makes these laundry detergents unable to completely remove or remove stubborn stains such as blood stains, protein stains and fat stains in a targeted manner
On the other hand, most of the laundry detergents currently on the market are ordinary, and there are few concentrated ones. According to the development trend of the industry, concentrated products will become more and more popular with consumers, because concentrated products can save energy and save energy. Moreover, there is also a great saving in raw materials and packaging materials. Although the price of concentrated products is higher than that of ordinary products, the effect of its use is also obvious. In contrast, concentrated products are more cost-effective

Abstract

The present invention discloses a protease super-concentrated laundry detergent, which mainly comprises, by mass, 3-38% of a non-ionic surfactant, 1-22% of an anionic surfactant, 0.1-1% of protease, 0.1-2% of triethanolamine, 0.1-2% of sodium citrate, 0.1-2% of refined salt and 60-70% of deionized water, wherein the protease comprises biological protease and compound protease. According to the present invention, the protease super-concentrated laundry detergent product is neutral and has characteristics of mild nature, no stimulation, soft hand-feeling, no alkaline residue after washing, no skin allergy and other symptoms, no damage on fabrics, water solubility, easy use, easy use amount control, easy storage, and easy use; and the process operation of the preparation method is simple, and the method is easily subjected to industrial production.

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...
