Technical Field

[0001] The present application relates to the field of sterilization and cleaning, and in particular to a long-lasting antibacterial floor cleaner. Background Art

[0002] More and more consumers are paying attention to floor cleaning. The commonly used method of using water to clean the floor is not effective and will leave bacteria. The detergents currently used on the market have added bactericidal ingredients, which can achieve long-term bactericidal effects while cleaning the floor. However, the detergent takes a long time to evaporate after use on the floor, affecting the living experience. Summary of the Invention

[0003] The embodiments of the present application provide a long-lasting antibacterial floor cleaner, which is used to improve the long-lasting antibacterial effect and quick drying of the floor cleaner.

[0004] The present application provides a long-lasting antibacterial floor cleaner, which is composed of the following components in parts by weight: 18-30 parts of anionic surfactant; 3-5 parts of a fungicide, which is a composite of a quaternary ammonium salt compound and polyhexamethylene biguanide hydrochloride; 2-4 parts of quick-drying agent, the quick-drying agent is N, N-bis (hydroxyethyl) cocamide; 1-3 parts of sodium fatty alcohol polyoxyethylene ether sulfate.

The amount of deionized water is made up to 100 parts, which means that the amount of deionized water added makes the total amount of the floor cleaner 100 parts.

[0006] In the present application, anionic surfactants are used to destroy the binding force between surface dirt and the floor, making the surface dirt easier to be wiped by cleaning tools. It is worth mentioning that there are calcium ions and magnesium ions in the dirt on the floor. Calcium ions and magnesium ions will combine with some anionic surfactants, especially linear alkylbenzene sulfonates, and affect the decontamination effect of the anionic surfactant. In the present application, a chelating agent compounded with ethylenediaminetetraacetic acid and sodium tripolyphosphate is used. The anions of the hydrolyzed ethylenediaminetetraacetic acid can chelate with calcium ions and magnesium ions, and the anions of the hydrolyzed sodium tripolyphosphate can also chelate with calcium ions and magnesium ions, thereby avoiding the chelation of the anionic surfactant by calcium ions and magnesium ions and affecting the decontamination effect. Adding a chelating agent compounded with ethylenediaminetetraacetic acid and sodium tripolyphosphate will make the anionic surfactant activity unstable in the floor cleaner. In the present application, fatty alcohol polyoxyethylene ether sodium sulfate is added as a cosolvent for the anionic surfactant, so that the anionic surfactant is stably dispersed in the floor cleaner, thereby improving the decontamination effect. In the present application, the bactericide is a composition of a quaternary ammonium salt compound and polyhexamethylene biguanide hydrochloride, polyhexamethylene biguanide hydrochloride is rich in positively charged guanidine groups, and quaternary ammonium salt compounds are cationic bactericides, and the surfaces of bacterial microorganisms such as Staphylococcus aureus and Escherichia coli are usually negatively charged, such as the phosphate groups of the phospholipid bilayer, and the strong attraction of this positive and negative charge causes polyhexamethylene biguanide hydrochloride and quaternary ammonium salt compounds to be rapidly adsorbed on the surface of bacterial microorganisms, inhibiting the ability of bacterial microorganisms to divide and reproduce, blocking their life cycle, and polyhexamethylene biguanide hydrochloride quaternary ammonium salt compounds form a physical coating on the surface of bacterial microorganisms, hindering bacterial microorganisms from breathing passages and nutrient intake. Wherein polyhexamethylene biguanide hydrochloride can achieve long-term bactericidal effect, and quaternary ammonium salt compounds have a better bactericidal effect. The combination of the two can achieve effective sterilization while also achieving long-term bactericidal effect. But the bactericide of quaternary ammonium salt compound and polyhexamethylene biguanide hydrochloride is positively charged or cationic, so that the bactericide can be combined with the anion in the anionic surfactant and affect the bactericidal effect and decontamination effect, in the present application, the ratio of ethylenediaminetetraacetic acid and sodium tripolyphosphate to the bactericide and anionic surfactant is regulated, and the chelating agent can reduce the bactericide and anionic surfactant and combine, so that the chelating agent, bactericide, and anionic surfactant synergistically promote bactericidal effect and decontamination ability. In the present application, quick-drying agent selects N, N-bis (hydroxyethyl) cocamide, N, N-bis (hydroxyethyl) cocamide realizes that floor cleaner can dry quickly after cleaning the ground, and N, N-bis (hydroxyethyl) cocamide is a nonionic surfactant, so that the decontamination effect of the anionic surfactant and the bactericidal effect of the bactericide are not affected while realizing that the floor cleaner is dried quickly. The solvent in the present application is used to form a stable and uniform mixed solvent for the above-mentioned components in the floor cleaner.

[0054] Comparative Example 14: Compared with Example 1, the ethylenediaminetetraacetic acid in the chelating agent was replaced by trisodium citrate, and the sodium tripolyphosphate isopropoxide was replaced by sodium gluconate. Other conditions were the same as those in Example 1.

[0055] The long-lasting antibacterial floor cleaners prepared from Examples 1 to 8 and Comparative Examples 1 to 14 in Tables 1 and 2 were evaluated by the following method. The evaluation results are shown in Table 3.

[0057] 2. Detergency test refers to QB / T4532-2013.

[0058] 3. Quick-drying test: The quick-drying floor disinfectant cleaner prepared by the present invention is added to a sweeping robot, and then the floor is mopped.

This indicates that the chelating agent composed of EDTA and sodium tripolyphosphate isopropoxide has a better synergistic effect with the other components at the ratio in Example 1.

[0064] From the analysis of the examples and comparative examples, it can be seen that in Comparative Examples 1 and 2, compared with Example 1, the amount of linear alkylbenzene sulfonate is increased or decreased, which is not within the ratio range of the present application, resulting in a decrease in the effect of the linear alkylbenzene sulfonate as an anionic surfactant and the synergistic effect of the other ingredients compared with Example 1.

[0065] Compared with Example 1, in Comparative Example 3 and Comparative Example 4, the amounts of didecyldimethylammonium chloride and polyhexamethylene biguanide hydrochloride in the fungicide are increased or decreased, which is not within the ratio range of the present application, so that the synergistic effect of the fungicide composed of didecyldimethylammonium chloride and polyhexamethylene biguanide hydrochloride and other ingredients is reduced compared with Example 1.

[0066] Compared with Example 1, in Comparative Examples 5 and 6, the dosage of the quick-drying agent is increased or decreased, so that the synergistic effect of the quick-drying agent and other ingredients is reduced compared with Example 1.

[0067] Compared with Example 1, the amount of co-solvent in Comparative Examples 7 and 8 is increased or decreased, so that the synergistic effect of the co-solvent and other ingredients is reduced compared with Example 1, indicating that the synergistic effect of the components in Example 1 of the present application is the best.
