Embodiment 1-3 and comparative example 1-2

[0280] Liquid detergent compositions A, B, C, A' and B' were formulated according to the composition of Table 1 below.

[0281] Each component and performance of liquid detergent composition A, B, C and A', B' in table 1 embodiment 1-3, comparative example 1-2

[0282]

[0283]

[0284] As can be seen from Table 1, the detergent composition of embodiment 1-3 has higher enzymatic activity under the environment of high content anionic surfactant, especially pesticide degrading enzyme has high activity retention rate. This is benefited from two aspects, and one is that chelating agent is added among the embodiment 1-3, and another is that among the embodiment 1-3, suitable enzyme preparation has been added. But compared with using GLDA as chelating agent in embodiment 1, in embodiment 3, using EDTA as chelating agent, under high temperature, the activity of pesticide degrading enzyme becomes lower, shows that the selection of chelating agent keeps very little to the activit...

Embodiment 1 and comparative example 3-5

[0286] Liquid detergent compositions A, C', D' and E' were formulated according to the composition of Table 2 below.

[0287] Each component and performance of liquid detergent composition A, C', D' and E' of table 2 embodiment 1 and comparative example 3-5

[0288]

[0289]

[0290] As can be seen from Table 2, Example 1 solves the problem that the detergent composition with a high content of enzyme preparation (the addition of enzyme preparation in the liquid detergent composition is greater than or equal to 0.5%) easily leads to a rise in viscosity after experiencing a high temperature environment. high defect. In all examples and comparative examples in the detailed description of the invention, the initial viscosity of all compositions was adjusted to 2500cP. However, as can be seen from Comparative Example 3, without adding ST2S and Thixome S-9, the initial state viscosity of the composition at -25°C is 2519cP, while the 45°C-viscosity change rate at -25°C is 3.2,...

Embodiment 1、 comparative example 4 and comparative example 6

[0292] Liquid detergent compositions A, D' and F' were formulated according to the composition of Table 3 below.

[0293] Each component and performance of liquid detergent composition A, D' and F' of table 3 embodiment 1, comparative example 4 and comparative example 6

[0294]

[0295]

[0296] As can be seen from Table 3, in Example 1, the isomeric fatty alcohol polyoxyethylene ether sulfate sodium has a special branched chain structure, which is conducive to impelling the surfactant to form a structure in the environment of high surfactant concentration or high protein concentration Simple micelle structure, rather than complicated micelle structure, specifically, utilize the steric hindrance characteristic of carbon chain branch to impel the micelle of liquid detergent composition to form the structure of spherical micelle or rod micelle, and Not a lamellar or worm-like micellar structure. It can be seen from the results in Table 3 that when using straight-chain AE...

Abstract

The invention relates to a detergent composition which is prepared from the following components in percentage by weight: 0.5-10% of an organophosphorus pesticide degrading enzyme, 0.2-5% of a washingenzymic preparation, 0.1-6% of a chelating agent, 0.3-5% of a component A, 6-30% of a surfactant, 0.01-25% of an auxiliary agent and 50-90% of water. The component A is a grafted copolymer of an acrylic polymer and fatty alcohol-polyoxyethylene ether or metal salt of the grafted copolymer. The detergent composition provided by the invention has a good removal action to oil stains, food dirt and pesticide residues and is high in viscosity stability and high in enzyme activity if being stored at a high temperature or for a long time.

Description

technical field [0001] The invention relates to the field of daily chemical products, in particular to detergent compositions. Background technique [0002] At present, tableware detergents mainly rely on surfactants to remove dirt. For example, detergent products are often compounded with anions such as sodium dodecylbenzene sulfonate and non-ionic surfactants such as partial oxyethylene ethers to achieve a certain level. However, the effect of surfactants is mainly for ordinary oil stains, and there are still certain limitations in the removal of some special stains and heavy oil stains. Generally speaking, there are often complexes between protein, starch and fat in prepared foods. These complexes adhere to porcelain and glassware, and it is difficult to quickly remove them with ordinary detergent after drying; some Saturated fats, such as lard, tallow, or suet mixed with other seasonings, adhere to porcelain or plastic utensils and are difficult to remove with surfactan...
