In view of the above, according to a first object of the embodiment of the present invention, there is provided a low-foaming and sterilizing dishwasher detergent, comprising the following components by weight: 10-25% of an alkaline composition; 1-3% of defoaming agent; 1-3% of a disinfectant; 1-10% of other auxiliary agents; the alkaline composition agent comprises the following components: 3-10% of alkaline cleaning agent by total weight of the cleaning agent; 1-5% of glycolipid biosurfactant and 5-10% of nonionic surfactant.

In this embodiment, the alkaline builder enhances the cleaning ability of the cleaner and saponifies the soil to make it soluble or dispersible in water. The defoaming agent which is preferably matched not only can be used for quickly defoaming, but also can be used for inhibiting foams for a long time, so that no foams exist in the spraying and washing process. The optimized bactericide can still keep activity in an alkaline system, and is a new generation of safe high-efficiency disinfectant and bactericide which can kill various bacteria and disease lives such as intestinal pathogenic bacteria, pyogenic coccus, pathogenic yeast, bacterial propagules, lipophilic viruses, H1N1 influenza diseases, AIDS and the like. Compared with the traditional disinfectant containing chlorine, aldehydes and phenols in the dishwasher cleaning agent, the disinfectant has the characteristics of broad spectrum, high efficiency, no toxicity, no stimulation, no corrosion, no residue and the like, and is widely accepted and applied internationally. The preferred detersive surfactant is modified green surfactant alkyl glycoside, has complete biodegradability and better wetting and detersive properties, has higher alkali resistance and low foam surface activity, is matched with strong alkali for use, and can clean the oil stain on tableware by spraying and cleaning in a dishwasher. The preferred performance additive is a green surfactant which reduces the residue on the ware and results in ware that is not bitter.

Wherein the low-foaming germicidal dishwasher detergent comprises 10-25% by weight of the alkaline composition, based on the total weight of the detergent, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25% or any value within the range, wherein the alkaline composition acts to enhance the cleaning ability of the detergent and saponifies the soil, allowing the soil to be dissolved or dispersed in water, as will be appreciated by those skilled in the art.

The nonionic surfactant in this embodiment acts as a synergistic effect with the ionic surfactant to enhance the washing ability, and when the weight percentage of the nonionic surfactant is too low, i.e., less than 5%, the detergency shows a tendency of increasing with the increase of the nonionic surfactant; when the weight percentage of the nonionic surfactant is too high, i.e., more than 10%, the detergency is remarkably reduced.

In some embodiments, the nonionic surfactant is selected from at least one of modified alkyl glycosides, fatty alcohol polyoxyethylene ethers, isomeric fatty alcohol polyoxyethylene ethers, modified fatty alcohol polyglycol ethers, fatty alcohol eo-po block polymers.

And (4) testing defoaming capability.

According to the GB/T13173.6 measurement of foaming power of detergent (Ross-Miles method), a detergent sample is prepared into a test solution with a certain concentration by using water with certain hardness. After 200ml of a sample solution was poured from a height of 90cm to the surface of 50ml of the same sample solution at the bottom of a graduated cylinder under a certain temperature condition, the height of the resulting foam was measured as the foaming power of the sample. The stopwatch was started immediately and the initial foam height (average height of foam edge and apex) was read when the solution in the drip tube was run off, and a second reading was taken at the end of 5 min.

Table 2 comparison of foam performance data for example 2 and comparative example 1

The experimental results show that the formulation of the product has lower foam height through the synergistic effect of the surfactant, the defoaming agent and the foam inhibitor in the formulation within the authority protection range. The specific expression is as shown in (1) example 2, example 3 and example 4, the used main detergent is nonionic, the initial foam height of the detergent is lower than that of the traditional anionic active foam, and the detergent can be compounded with the defoaming agent to actually present lower foam height; (2) The selected defoaming additive SAG638 and the defoaming agent 1410 have stable defoaming performance under alkaline conditions; (3) The foam inhibitor LF8 is selected, so that the height of foam can be well inhibited, and the actual use requirement can be normally met. (4) The choice of using a surfactant outside the scope of the formulation authority, such as the anionic surfactant chosen in comparative example 1, gives a high foam height.

And (5) testing the sterilizing performance.

According to the technical specification of disinfection, the sample is diluted by adding water according to the ratio of 1. The specific experimental results are as follows:

table 3 comparison of data on bactericidal properties of example 3 and example 4

The experimental result shows that the killing log values of the formula in the authority protection range to escherichia coli (8099) and staphylococcus aureus (ATCC 6538) are all more than or equal to 5.00, and the formula meets the standard value specified in disinfection technical Specification 2022 edition-2.1.1.7.7.
