Stable, efficient and strong-permeability tableware washing composition and preparation method thereof

Technical Field

The invention relates to the technical field of daily chemical industry, in particular to a stable, efficient and strong-permeability tableware washing composition and a preparation method thereof.

Background

With the rapid development of society and the improvement of living conditions of people, people are increasingly paying attention to washing efficiency. Especially for the dish washing composition, more detergent is often added when washing some heavy greasy dishes, so that not only is the detergent greatly consumed, but also the excessive detergent increases the water washing consumption, and is a waste of water resources. In the aspect of tableware washing, the demands of people are not limited to the cleaning effect of common detergents, but the demands of people are more hopeful to increase the washing efficiency, reduce the frequency of purchasing and reduce the waste of resources.

Detergent products currently on the market show a diversified trend. The main component of the oil emulsion is surfactant, and the surfactant has the effects of reducing the surface tension and emulsifying the oil. In the prior art, such as CN112759754A, a low-foam biodegradable nonionic surfactant is used, so that the interfacial film strength is reduced, the foam stability of the surfactant is improved, and the synergistic effect and emulsifying capacity of molecules and long-chain grease are enhanced. However, the amount of the nonionic surfactant added to the dish washing detergent cannot be increased, and the cloud point of the whole system is likely to be high, the nonionic surfactant is likely to be precipitated, and the dish washing detergent is not easy to wash. In view of the above problems, it is necessary to develop a dish detergent which has strong permeability to oil stains, accelerates emulsification, is easy to wash, and shortens the washing time.

In view of the foregoing, there is a need to develop a novel solution for a stable, highly penetrating dishwashing composition that solves the problems of the prior art.

Test example 1

Decontamination performance test

The stable, high penetration dishwashing compositions prepared in examples 1-4 and comparative examples 1-3 were tested for detergency according to GB/T9985-2022, and included two methods: one is a foam-in-place method, which is based on the principle that greasy dirt washed from a dirty plate can produce a defoaming effect, and judging how many plates can be washed by 1L of a detergent water solution with the concentration of 2g/L according to the attenuation degree of foam; the other is a degreasing method, which is based on the principle that stubborn stains are smeared on a hard surface carrier, the stains are separated from the hard surface under the flushing of a 1L detergent water solution with the concentration of 2g/L, and the degreasing rate is judged by quantifying the cleaning rate of the stains.

The test results are shown in Table 2.

Table 2 decontamination test results

As can be seen from Table 2, examples 1-4, which were formulated with the modified polyether surfactant and the remaining surfactant, had good permeation and detergency, and the detergency was significantly better than comparative examples 1-3. In comparative examples 1-3, the sodium dodecyl benzene sulfonate, the unmodified nonylphenol polyoxyethylene polyoxypropylene ether and the rest components are compounded, and the N-octyl pyrrolidone is removed, so that the decontamination effect is obviously reduced, which shows that the compounding of the modified polyether surfactant and the rest components of the detergent can generate a stronger synergistic effect, and the decontamination performance of the product is improved. The sample prepared by the technical scheme of the invention has excellent decontamination performance, and can give consideration to the performance of oil removal and dish washing number in two dimensions, so that the sample can bring remarkable benefits to consumers in practical application, can efficiently remove various stubborn greasy dirt such as animal grease on plastic tableware, and can clean more tableware by using the same amount of detergent.

Test example 2

Evaluation of oil removal Effect

The vegetable oil is uniformly smeared on tableware, then the tableware smeared with the vegetable oil is respectively soaked in the aqueous solutions (the washing compositions: water=1:250, m/m) of the washing compositions of the examples 1-4 and the comparative examples 1-3, the scene of actual bowl washing and degreasing is simulated, the time of all suspended oil drops is counted, and the time of suspension of which sample is shorter can be considered to have better degreasing effect.

The evaluation results are shown in Table 3.

Example 2	220
		Example 3	208
Example 4	193
		Comparative example 1	268
Comparative example 2	256
		Comparative example 3	249

From Table 3, it can be seen that the modified polyether surfactant of the examples and N-octyl pyrrolidone and other components can effectively exert a synergistic effect, and more rapidly emulsify oil droplet molecules, so that oil droplets can be rapidly peeled off the surface of tableware. The detergent compositions of comparative examples 1-3, in which the modified polyether surfactant was replaced with the conventional surfactant sodium dodecyl benzene sulfonate, the unmodified nonylphenol polyoxyethylene polyoxypropylene ether, and the N-octyl pyrrolidone was removed, respectively, had reduced synergistic effects between the components and significantly reduced oil removal.
