[0042] Relevant experimental data and instructions: We designed the following experiment for this multifunctional antibacterial soothing moisturizer containing lavender essential oil: Antibacterial test and breath test were designed for the long-lasting antibacterial tooth protection breath freshener.

[0043] 1. Antibacterial experiment The bacteria used in the antibacterial test were Staphylococcus aureus, which can exist in large quantities in the air and on the human epidermis. A bacterial solution was prepared according to the method in GB / T20944.1-2007, and a sterile culture medium was prepared at the same time. The moisturizing creams of the five embodiments were evenly coated on the surface of the sterile culture medium in equal amounts, and then the Staphylococcus aureus bacterial solution was evenly coated on the sterile culture dish coated with the moisturizing cream after selecting a suitable concentration. After culturing for 8 hours and 24 hours, the area change of the bacteria on the culture medium was observed, and the antibacterial rate was calculated.

[0044] 2. Lactic acid stinging evaluation test The score of the lactic acid stinging test before and after using the product can directly reflect the product's repair function on the skin barrier function. Test environment: The test environment temperature is 25±1℃, the humidity is 50±5%, and real-time dynamic testing is performed. The total number of test volunteers is 50, aged between 20-60 years old, 10 people in each group, a total of 5 groups, the test participants have no serious systemic diseases, no immunodeficiency or autoimmune diseases, no history of allergies to skin care products, and the test participants cannot use any products on the test site within 2-3 days before the test, and they should fill out the informed consent form before the test.

[0045] Test steps: The subjects sit quietly in a relatively constant temperature and humidity room for 30 minutes, and the subjects are respectively treated with equal amounts of 10% lactic acid aqueous solution and distilled water on the left and right nasolabial grooves. The subjects are asked about their skin sensation symptoms at 1, 2, 3, and 5 minutes, and scored according to a four-point scale: no tingling sensation 0 points, mild tingling sensation 1 point, moderate tingling sensation 2 points, and severe tingling sensation 3 points. The tester and the measurement personnel should correspond one to one.

[0046] Test result data calculation: The formula for calculating the improvement rate of lactic acid stinging is: R=(R1-R2) / R1*100%, where R is the improvement rate of lactic acid stinging (%), R1 is the lactic acid stinging score before using the sample, and R2 is the lactic acid stinging score after using the sample for 28 days. Wherein, the lactic acid stinging score = the subject's lactic acid stinging score at 1 minute + the subject's lactic acid stinging score at 2 minutes + the subject's lactic acid stinging score at 3 minutes + the subject's lactic acid stinging score at 5 minutes.

[0047]

[0048] According to the data in Table 1, it can be seen that this multifunctional antibacterial soothing moisturizing cream containing lavender essential oil has a strong antibacterial function, and the antibacterial function lasts for a long time. The skin lactic acid stinging test can prove that this product has a strong effect on improving skin sensitivity and soothing the skin.
