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 invention discloses a protease super-concentrated laundry detergent, which is mainly composed of the following raw materials in mass percentage: 3% to 38% of nonionic surfactant, 1% to 22% of anionic surfactant, 0.1% to 1% of Protease, 0.1%-2% triethanolamine, 0.1%-2% sodium citrate, 0.1%-2% refined salt and 60%-70% deionized water; protease includes biological protease and compound protease. The protease super-concentrated laundry detergent of the present invention has mild neutral properties, no irritation, soft hand feeling, no alkaline residue left after washing, no skin allergies and other symptoms, no damage to fabrics, and at the same time Easily soluble in water, easy to use, easy to control the dosage, easy to store and easy to use. The preparation method of the invention has simple process operation and is easy to realize industrialized production.

Description

technical field [0001] The invention relates to a laundry detergent, in particular to a protease super-concentrated laundry detergent and a preparation method thereof, belonging to the field of daily chemicals. Background technique [0002] With the continuous development of modern society, household detergents have gradually developed from soap and washing powder to today's laundry detergent. The new generation of laundry detergent has gradually been accepted by domestic consumers. Many types of laundry detergents have appeared on the market. Laundry liquid products. [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, so that these laundry detergents cannot completely remove or have poor removal effect on some stubborn stains, such as blood stains, protein stains and fatty stains. On the other hand, most of the laundry detergen...
