Abstract
The invention discloses a stable and efficient high-permeability tableware washing composition and a preparation method thereof, wherein the composition comprises the following components in parts by weight: 10-40 parts of surfactant, 0.2-3 parts of alkaline neutralizer, 7-10 parts of modified polyether surfactant, 0.5-5 parts of polyester polyether copolymer, 0.1-12 parts of auxiliary agent, 0.1-5 parts of N-alkyl pyrrolidone and 10-70 parts of water. The modified polyether surfactant is obtained by reacting alkylphenol polyoxyethylene polyoxypropylene ether with sultone, a polyoxypropylene polyoxyethylene block (PO-EO) structure is introduced between traditional hydrophilic and hydrophobic groups, the PO group has strong hydrophobicity and the EO group has strong hydrophilicity, the structure enables polarity transition between the hydrophilic and hydrophobic groups to be more gentle, so that the modified polyether surfactant has excellent interfacial activity and stability, and has strong emulsification and permeation effects on the basis of good solubility.
Description
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.
Disclosure of Invention
Based on the above, the invention provides the stable and high-efficiency strong-permeability dishwashing composition and the preparation method thereof, and the stable and high-efficiency strong-permeability dishwashing composition has high-efficiency permeability and good stability.
An object of the present invention is to provide a stable, high-efficiency, penetrating dishwashing composition comprising the following components in parts by mass:
wherein the modified polyether surfactant is obtained by reacting alkylphenol polyoxyethylene polyoxypropylene ether with sultone.
Further, the preparation method of the modified polyether surfactant comprises the following steps:
S1, mixing alkylphenol polyoxyethylene polyoxypropylene ether with sodium hydride, and stirring for reaction to obtain an intermediate product;
S2, mixing sultone and the intermediate product, heating for reaction, and purifying to obtain the modified polyether surfactant.
Further, the sultone is selected from one or more of 1, 3-propane sultone, 1, 4-butane sultone and 1, 4-butene sultone.
Further, in the step S1, the mol ratio of the alkylphenol polyoxyethylene polyoxypropylene ether, the sodium hydride and the sultone is (1-2): 1-3.
Further, the temperature of the stirring reaction in the step S1 is 20-40 ℃, and the reaction time is 0.5-1h.
Further, the temperature of the temperature rising reaction in the step S2 is 40-65 ℃, and the reaction time is 5-8h.
Further, the auxiliary agent is selected from one or more of pH regulator, thickening conditioner, preservative and essence.
Further, the polyester polyether copolymer has the following structural general formula:
Said n is selected from integers from 6 to 100;
And m is an integer from 1 to 15.
Specifically, the surfactant is selected from one or more of anionic surfactant, nonionic surfactant and zwitterionic surfactant.

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.
