Test example I, patch test on human skin

The antibacterial hand sanitizer prepared in examples 1-5 and comparative examples 1-5 of the invention is tested according to related requirements and determination methods of a human skin patch test in 2015 edition of cosmetic hygiene code issued by the ministry of health, skin reactions are observed at 0h, 6h, 12h, 24h and 48h respectively, the experimental results of all volunteer subjects are negative results, and no adverse skin reaction occurs. The antibacterial hand sanitizer provided by the invention has the advantages of no anaphylactic reaction, no irritation and high safety.

Test example two evaluation of bacteriostatic Activity

The bactericidal effect of the bacteriostatic hand sanitizer prepared in examples 1 to 5 and comparative examples 1 to 5 on staphylococcus aureus, escherichia coli, candida albicans and candida albicans is determined by referring to a sterilization method in appendix C of 15979-2002 hygienic Standard for Disposable sanitary articles, and the calculated bacteriostatic rate (%) is shown in table 1.

TABLE 1 results of the test of the bacteriostatic activity

The results show that the antibacterial hand sanitizer prepared in the examples 1-5 has good antibacterial effect on staphylococcus aureus, escherichia coli, candida albicans and candida, and the antibacterial rate is up to more than 99.0%, which is superior to that of the hand sanitizer in the comparative examples 1-5. As can be seen from comparative examples 1-3, eugenol glucoside has certain inhibitory activity on bacteria and fungi, repa germanium has weaker inhibitory activity on bacteria and fungi, and the inhibitory activity on the bacteria and the fungi is obviously improved by compounding eugenol glucoside and the repa germanium according to a certain proportion, and the synergistic inhibitory activity is generated by compounding the eugenol glucoside and the repa germanium. As shown in comparative examples 4-5, kaempferol-7-glucoside and repatriage cannot generate obvious synergistic bacteriostatic effect when used together.

Test example III evaluation of foaming Properties

And (3) adding 0.5mL of prepared sample and 20mL of distilled water into a test tube, plugging the opening of the test tube by using a thumb to ensure that the direction strength tends to be consistent, shaking for 30 times, adding 20mL of distilled water along the tube wall, and flushing the foam on the tube wall. Two values need to be recorded, the first is the stable height of the foam which does not drop after shaking, the height is used for measuring the foaming performance of the hand sanitizer, and the second is the time consumed by destroying the foam to half of the original height after adding the clean water slowly, and is used for representing whether the generated foam is stable or not. The procedure was repeated three times and data and average values for each group were recorded and the results are shown in table 2.

TABLE 2 evaluation results of foaming Properties

Group of	Foam height/mm	Time/s for foam to collapse to half of original height
			Example 1	135	37
Example 2	127	31
			Example 3	129	33
Example 4	134	36
			Example 5	130	34

According to the requirements of national standards, the height of the foam is more than or equal to 100mm, the time for the foam to be damaged to half of the original height is more than 25s, and the test liquid soap meets the requirements, so that the finished liquid soap is proved to have good foam performance. As shown in Table 2, the bacteriostatic hand sanitizer prepared in the embodiments 1 to 5 of the present invention has good foaming and foam stabilizing properties.

Test example four evaluation of Using effects

Screening 100 volunteers, dividing the volunteers into an example 1-5 group and a comparative example 1-5 group, carrying out sensory evaluation on 10 persons in each group by correspondingly using the hand sanitizer prepared in the examples 1-5 and the comparative examples 1-5 of the invention, carrying out the evaluation on 10 points with the highest point of 10 points and the lowest point of 0 point, averaging the points scored by all the volunteers, and counting the performance evaluation results of the volunteers on the product, wherein the results are shown in a table 3.

TABLE 3 evaluation results of Using effects

The results show that the hand sanitizer prepared in the examples 1-5 has abundant foam, is easy to wash, has strong detergency, low irritation and good moisturizing property, and the total using effect score is better than that of the hand sanitizer prepared in the comparative examples 1-5.
