Problems solved by technology

This is because the enzyme itself is a protein structure, and the enzyme is in an active state in the liquid detergent. The protease can decompose and destroy other enzymes, and even decompose the protease itself. Therefore, other enzymes cannot be combined with the protease in the same system, even if the liquid containing a single protease Detergents have a shorter shelf life
The multi-enzyme detergent in the form of solid particles does not interfere with each other, which is good for storage. However, when using it, the solid particles containing multi-enzyme must be dissolved and dispersed in water to release the enzyme and generate activity, which is inconvenient to operate.

Abstract

The invention relates to a detergent, in particular to a multienzyme detergent. The liquid multienzyme detergent comprises the following components by weight percentages: surfactant, 5 to 40; triethanolamine, 5 to 30; ethanol, 2 to 10; sodium silicate, 1 to 10; nipagin ethyl ester, 0.05 to 2; protease, 0.1 to 2; amylase, 0.1 to 2; cellulase, 0.05 to 1; lipase, 0.05 to 1; the rest is water. The preparation method for the liquid multienzyme detergent is as follows: according to the content and components, water is added to the surfactant which is heated to the temperature of 60 to 80 DEG C for dissolution; the nipagin ethyl ester and the sodium silicate is added and stirred for dissolution; when the mixture is cooled to the temperature of 30 to 40 DEG C, the triethanolamine and the ethanol are added and mixed evenly; the protease, the amylase, the cellulase and the lipase are added and stirred evenly, thus obtaining the liquid multienzyme detergent. When in use, the liquid multienzyme detergent needs only diluting in water, so the operation is convenient.

Description

technical field [0001] The present invention relates to a detergent, in particular to a multi-enzyme detergent and a preparation method thereof. Background technique [0002] The application of enzymes in detergent products is one of the major technological advancements in the development of the detergent industry. At the beginning, a single protease was used. Later, the application of amylase, cellulase and lipase, as well as the synergistic application of two or more enzymes, were successively developed. These developments have significantly improved the comprehensive performance of detergents and greatly improved product quality. [0003] The multi-enzyme detergents currently on the market that contain two or more enzymes are all in the form of solid particles, while the enzyme-containing liquid detergents usually contain only a single protease. This is because the enzyme itself is a protein structure. In the liquid detergent, the enzyme is in an active state. The prote...
