Performance testing

1. Sensory evaluation

The test method comprises the following steps: the 50 subjects were equally divided into 10 groups and given samples at random according to the "double-blind" test, and were asked to wash their hands at random with the amount of disinfectant used and the time spent.

Evaluation criteria: the subjects were scored according to their feelings using a 5-point scale, wherein smooth feeling, moist feeling and irritation were all 1 point worst and 5 points best, and the test results are shown in table 1.

TABLE 1 sensory evaluation results

As can be seen from the test results in Table 1, the disinfectant of examples 1 to 5 had a smooth feeling, moist feeling, and irritation evaluation score of 4.5 to 4.8, 3.5 to 4.7, and 5, and the overall score evaluation was high. The disinfectant in comparative examples 1-3 has smooth feeling and moistening feeling of only 1 point, and irritation of 4.5-4.6 points, i.e. the disinfectant prepared has no smooth feeling and moistening feeling and poor use experience under the condition of not adding foaming agent and thickening agent. The disinfectant liquids of comparative examples 4 to 5 were found to have a smooth feeling and a moist feeling of 3.2 to 4.5 minutes and 4.2 to 4.8 minutes, which were slightly inferior to those of examples 1 to 5 and better than those of comparative examples 1 to 3.

2. Sterilization test strains: staphylococcus aureus (ATCC 6538); escherichia coli (8099); candida albicans (ATCC 10231).

Preparing a bacterial suspension: staphylococcus aureus, Escherichia coli and Candida albicans cultured for 24h were diluted with 5mL of sterile distilled water into bacterial suspensions in 0.03 mol/L phosphate buffer containing 1% peptone, respectively, at pH 7.2-7.4.

And (3) sterilization experiment: taking 1mL of the bacterial suspension into a sterile test tube, keeping the temperature in a water bath at 19-21 ℃, adding a certain amount of disinfectant, uniformly mixing, oscillating, acting for a specified time, taking 0.5mL of the bacterial-drug mixed solution, uniformly mixing in 4.5mL of a neutralizer, taking 1mL of the solution or diluent after the neutralization for 10min, inoculating a sterile plate, pouring a common nutrient agar culture medium, culturing for 48h in a 37 ℃ incubator, counting the number of bacterial colonies of the plate, averaging the experiments for three times, taking an average value, calculating the sterilization rate to be more than or equal to 99.96%, oscillating the water bath for the time and adding the disinfectant, and recording the test results into Table 2.

TABLE 2 Sterilization test results

As can be seen from the test results in Table 2, the time required for the disinfection solution in examples 1-5 to reach a sterilization rate of 99.96% or more is 1.5-1.7min, and the minimum required amount is 2 mL; the time required for the sterilization rate of the disinfectant in comparative examples 1, 2 and 4 to reach more than 99.96 percent is 2.6-4.0min, and the minimum required dosage is 3-4 mL; in comparative examples 3 and 5, as the foaming agent and the thickening agent are not added, the sterilization time is 2.6min and 2.2min respectively, and the minimum consumption of the required disinfectant is 3mL and 2mL respectively. The polyhexamethylene guanidine can play a role in synergism after being added with the foaming agent and the thickening agent, can achieve a good sterilization effect in a short time only by using less disinfectant, and greatly reduces the cost.
