Several laundry beads were prepared according to the ingredient contents of example 1 and comparative examples 1 to 8 in table 1 to perform stability (including film and inner material), detergency, bacteriostasis, and water solubility tests;
wherein, the stability evaluation is carried out by taking 3 of the prepared washing gel beads, placing the washing gel beads in an oven at 25 ℃ and 50 ℃ for 30 days, and observing whether the washing gel beads change or not after returning to the normal temperature; the detergency test detects the detergency of the washing gel bead according to GB/T13174-2008 'determination of detergency and circulating washing performance of detergent for clothing'; according to QB/T2738-2012 'evaluation method for antibacterial effect of daily chemical products', a strain is selected as staphylococcus aureus, and the antibacterial rate of the washing gel beads is detected; water solubility test 1g of the formulation was weighed out and dissolved in 99g of water, stirred and dissolved, and the final condition of the solution was observed.
Specific results are shown in table 2:
combining example 1 with comparative example 1, it can be seen that when the mass percent of sodium alcohol ether sulphate in each laundry bead is less than 30%, the ability of the bead formulation to inhibit staphylococcus aureus is significantly reduced, i.e., the bead formulation prepared according to the present application.
Combining example 1 and comparative example 2, it can be seen that the carbon chain of the fatty alcohol in the sodium fatty alcohol polyoxyethylene ether sulfate is preferably C12, and when the carbon chain of the fatty alcohol is not C12, the viscosity of the bead-forming formula solution is high, the freezing point is high, and further the beads are difficult to package into a film, are difficult to dissolve in water, and do not conform to the appearance of a transparent liquid.
Combining example 1 and comparative example 3, it can be seen that the carbon chain of the fatty alcohol in the sodium alcohol polyoxyethylene ether sulfate is C12, and the mass percentage of the fatty alcohol with the carbon chain of C12 in the sodium alcohol polyoxyethylene ether sulfate is not less than 60%, when the mass percentage is less than 60%, the viscosity of the bead-forming formula solution is high, the freezing point is high, and further the beads are difficult to package into a film, are not easy to dissolve in water, and are not in accordance with the appearance of a transparent liquid.
Combining example 1 and comparative example 4, it can be seen that the mass percent of deionized water in each bacteriostatic laundry bead is not higher than 30%, and when the mass percent of deionized water is higher than 30%, the bead membrane cannot be kept stable, and the bead membrane is easy to be damaged.
Combining example 1 and comparative examples 5-7, it can be seen that the mass percent of methyl laurate ethoxylate in fatty acid methyl ester ethoxylate is not less than 90%, the average EO addition number is preferably 8-15, and when the mass percent of methyl laurate ethoxylate in fatty acid methyl ester ethoxylate is less than 90%, the viscosity of the laundry bead formulation solution is greater; when the average EO addition is below 8 or above 15, the beading formulation is less water soluble.
Combining example 1 with comparative example 8, it can be seen that when the ratio of sodium fatty alcohol polyoxyethylene ether sulfate, fatty acid methyl ester ethoxylate and lauric acid monoglyceride is not in the range of 6 ± 0.1:2 ± 0.1:1, the bead membrane cannot be kept stable and the phenomenon of breakage occurs when the moisture content of the formulation solution is still unchanged.
The application also discloses a preparation method of the antibacterial laundry gel bead, which comprises the following steps:
1) cleaning and disinfecting equipment such as a reaction kettle, a taking tool, a pre-storage container, a material weighing container and the like, and checking whether the equipment runs normally or not;

3) weighing dodecylbenzene sulfonic acid and triethanolamine according to the formula ratio, adding the dodecylbenzene sulfonic acid and the triethanolamine into the solution A, stirring and neutralizing, and controlling the pH to be approximately equal to 8 according to the prior art to obtain a solution B;
4) weighing fatty alcohol-polyoxyethylene ether sodium sulfate according to the formula ratio, slowly adding the fatty alcohol-polyoxyethylene ether sodium sulfate into the solution B while stirring to prevent gel from appearing, and thus obtaining a solution C;
