Highly-concentrated enzyme-containing liquid detergent free of enzyme stabilizer

Abstract

The invention relates to a highly-concentrated enzyme-containing liquid detergent free of an enzyme stabilizer. The highly-concentrated enzyme-containing liquid detergent comprises the following components in percentage by mass: 21-25% of lauryl polyoxyethylene ether sodium sulfate, 5-27% of branched-chain alkyl ethoxy polyglycosides, 13-18% of AEC, 0.01-0.1% of protease, 0.1-0.5% of other additive and the balance of deionized water. The highly-concentrated enzyme-containing liquid detergent uses the branched-chain alkyl ethoxy polyglycosides, and the branched -chain alkyl ethoxy polyglycosides is a green, environment-friendly surfactant having a relatively small effect on the protease activity and is helpful to exertion of the protease activity; the water content in highly-concentrated enzyme-containing liquid detergent is also reduced and no enzyme stabilizer is added, so that the life of protease is prolonged; through reasonable allocation of three surfactants, the detergency is enhanced and the amount of the liquid detergent consumed in each time is reduced, so that the packaging cost and the transportation cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of daily chemical industry, and in particular relates to a highly concentrated enzyme-containing laundry detergent without an enzyme stabilizer. Background technique [0002] Laundry liquid is a new generation of clothes washing products. The market scale is expanding rapidly, and there is a tendency to gradually replace traditional washing powder. The concentration of active substances in the product is only 15%. Such a concentration specification leads to problems such as fast consumption of single-package products, high packaging and transportation costs, and insufficient detergency for heavy-duty clothes. [0003] On the other hand, the washing effect of detergent on protein stains such as blood stains and milk stains is mainly due to the addition of special ingredients such as protease in the product, but this technology cannot be applied to ordinary laundry detergent products, mainly because of the use...

Problems solved by technology

[0002] Laundry liquid is a new generation of clothes washing products. The market scale is expanding rapidly, and there is a tendency to gradually replace traditional washing powder. The concentration of active substances in the product is only 15%. Such a concentration specification leads to faster consumption of single-package products, higher packaging and transportation costs, and insufficient detergency for heavy-duty clothes.

[0003] On the other hand, the washing effect of detergent on protein stains such as blood stains and milk stains is mainly due to the addition of special ingredients such as protease in the product, but this technology cannot be applied to ordinary laundry detergent products, mainly because of the use environment required by protease More stringent: first, the water content should not be too high, and second, it is not suitable to use surfactants such as alkylbenzene sulfonate that can inactivate proteases

The mainstream products in my country's laundry detergent market contain nearly 85% of water, and generally use low-cost alkylbenzene sulfonate as the main surfactant, which leads to rapid inactivation of protease in the solution system and cannot guarantee a sufficient shelf life

In response to this problem, the solution reported at this stage is to add stabilizers such as borax and propylene glycol to properly prolong the life of the protease, such as the Chinese patent with the patent number ZL201210215756.9, which requires the addition of enzyme stabilizers to obtain qualified products , Another example: the Chinese patent with patent number ZL201110160696.0 also uses the addition of an enzyme stabilizer to prepare an enzyme-containing concentrated laundry detergent, but the stabilizer does not contribute to the washing process itself, and it is easy for consumers to increase product costs. Resentment over the addition of too many chemicals
