Experiment for inhibiting bacteria

The wet tissues of examples 1-5 and comparative examples 1-4 were subjected to an antibacterial rate test with reference to appendix C of GB15979-2002 hygienic Standard for Disposable sanitary articles, test methods for sterilizing, bacteriostatic and stability of the products, and the action time was 5 minutes, and the results are shown in Table 1.

0.5 g of the gel was placed in a petri dish and 1X 10 was added⁸Shaking cfu/ml bacterial suspension and 49ml antibacterial water on an oscillator for 5, 15 and 30min, standing for 30min, taking 1ml of the treated bacterial suspension for 10-fold gradient dilution, taking 1ml of the treated bacterial suspension and a culture dish, adding a culture medium which is melted and cooled to about 40 ℃, shaking uniformly, culturing at 37 ℃ for 72h, and calculating the bacteriostasis rate, wherein the test results are shown in the following table 1:

TABLE 1

Wherein "-" means substantially no bactericidal effect.

As can be seen from table 1, the bacteriostatic compositions of examples 1-4 have strong bacteriostatic action. In addition, comparative example 1 is different from example 2 in that comparative example 1 does not contain the camphor leaf essential oil, and the amount of the camphor leaf essential oil of Hongya is twice that of example 1. Comparative example 2 compares to example 2 with the difference that comparative example 2 does not contain the essential oil of cinnamomum hongkongense leaf and the essential oil of cinnamomum camphora leaf is twice as much as example 2. As can be seen from Table 2, even if the concentration of the essential oil of Cinnamomum japonicum leaf or the essential oil of Cinnamomum camphora leaf is increased, the bacteriostatic effect is not as good

Example 2, it can be speculated that there may be a synergistic effect between essential oil of leaves of Cinnamomum japonicum and essential oil of leaves of Cinnamomum camphora.

In addition, the difference between example 1 and example 2 is that the bamboo leaf extract and the lonicera confusa extract are also added in example 2, and as can be seen from table 2, the bacteriostatic effect of example 2 is improved to a certain extent after the extracts are added.
