Enzyme-containing washing powder for low-temperature washing

Abstract

The invention relates to the field of washing agents and discloses enzyme-containing washing powder for low-temperature washing. The washing powder of the invention is prepared from the following ingredients (by weight): 25-35 parts of sodium dodecyl benzene sulfonate, 15-25 parts of coconut oil fatty acids, diethanolamine, 1-3 parts of embedding compound enzyme, 35-45 parts of a filler, 0.5-1.5 parts of carboxymethyl cellulose, 2-4 parts of an aloe extract, 1-3 parts of an oil-tea-cake extract and 1-3 parts of modified crab shell meal. The enzyme-containing washing powder has excellent dissolving efficiency in low-temperature water. In addition, the compound enzyme can maintain high activity at low temperature and in different acid-base environments such that the washing powder has excellent decontamination capability.

Description

technical field [0001] The invention relates to the field of detergents, in particular to an enzyme-containing washing powder suitable for low-temperature water washing. Background technique [0002] There are many types of washing powder products on the market at present. To further improve detergency and the ability to break down stains, enzymes are added to many brands of laundry detergent. Different enzymes are unique and can degrade specific stains in a targeted manner. For example, lipase can effectively degrade oil stains, and protease can effectively degrade proteins. [0003] For example: patent CN201410451148.7 discloses a compound enzyme laundry detergent, the components and their mass parts are: compound enzyme 0.5-3%, alkylbenzene sulfonic acid 10-20%, soda ash 10-20%, bubble flower Alkali 10-25%, Yuanming powder 30-60%, CMC 1-10%, fluorescent whitening agent 0.1-1%, embellishment 5-15%, essence 0.5-3%. The compound enzyme is compounded by two or more of alka...

AI Technical Summary

Problems solved by technology

[0005] 1. In low-temperature water, especially when the water temperature is lower than 10°C in winter, since the water temperature is already significantly lower than the optimal activity temperature of the enzyme (usually between 25-40°C), the enzyme cannot fully exert its activity, resulting in Severely reduced decontamination ability

In addition to the influence of temperature on enzyme activity, there is also a problem in the lower water temperature of the washing powder in the prior art: due to the lower water temperature, the washing powder cannot be dissolved quickly, and it takes a long time to fully dissolve. , usually the washing powder is automatically added to the water by the fully automatic washing machine during the cleaning process, and there is not enough time to wait for the washing powder to dissolve, which will cause the washing powder to not fully play its role

And if artificially doped with hot water to increase the temperature, it is more troublesome

[0006] 2. Existing laundry detergents are generally alkaline. In an alkaline environment, the activity of many enzymes will also be inhibited, so the enzymes cannot fully exert their activity, resulting in a serious decline in decontamination ability
