[0117] Test Example 3

[0118] Moisturizing effect measurement

[0119] 150 healthy volunteers, including 75 males and 75 females, aged 20 to 40 years, without severe systemic diseases, immunodeficiency or autoimmune diseases, no allergies to cosmetics, no acute facial inflammation, no use of hormone drugs or immunosuppressants, no participation in other clinical trials, and no application of topical preparations were selected. They were randomly divided into 15 groups, with 10 people in each group. The moisturizing lip balms provided by the above-mentioned Application Examples 1-8 and Comparative Application Examples 1-7 were applied to the lip skin of the volunteers in each group. The moisture content of the lip skin was tested using a skin moisture tester (CorneometerCM825) at 0 min, 30 min, and 60 min to evaluate the moisture content of the skin before and after use of the lipstick. The specific test results are shown in Table 5 below.

[0120] Table 5

[0121] The data in Table 5 demonstrate that the lip balms prepared in Examples 1-3 exhibit excellent moisturizing effects, with skin moisture reaching over 68% at 0 h, remaining over 64% after 30 min, and over 59% after 60 min. Comparative Example 7 demonstrates that the lip balm containing the moisturizing composition of the present disclosure can rapidly moisturize the lip skin and lock in moisture. Comparative Examples 1-6 demonstrate that the shea butter, cocoa seed butter, white beeswax, wheat germ oil, rice germ oil, and squalane in the moisturizing composition exhibit a synergistic effect, resulting in a significant moisturizing and synergistic effect.

[0122] Test Example 4 Antioxidant Test

[0123] (1) Take 1 g of the moisturizing lip balm of Application Examples 1 and 5-8, add 2 mL of anhydrous ethanol, and after complete dissolution, add 2 mL of 60 μmol / L DPPH solution and mix well. Let it stand for 30 minutes, adjust to zero with anhydrous ethanol, and measure the absorbance at 517 nm as Ai; in the same way, take 2 mL of anhydrous ethanol solvent + 2 mL of DPPH solution and mix well to measure the absorbance as Ac; take another 1 g of the composition matrix and dissolve it, add 2 mL of anhydrous ethanol, and then add 2 mL of anhydrous ethanol solvent and mix well to measure the absorbance as Aj.

[0124] The free radical scavenging rate was calculated according to the following formula.

[0125] Clearance (%) = [1-(Ai-Aj) / Ac] × 100%

[0126] Among them, Aj is the contribution of the reaction sample itself to the absorbance; Ai is the absorbance value of the sample after the action of DPPH; Ac is the absorption of DPPH itself at the measurement wavelength.

[0127] The DPPH free radical scavenging rate reflects its antioxidant capacity to a certain extent. The higher the scavenging rate, the better the antioxidant capacity. The results are shown in Table 6 (each sample group was measured 5 times in parallel, and the data are presented as average values).

[0128] The specific test results are shown in Table 6:

[0129] Table 6

[0130] As shown in Table 6, Application Examples 1 and 5 show that the lip balm of the present invention has a good scavenging effect on DPPH by adding plant extracts with antioxidant efficacy, with a scavenging rate of more than 85%. As shown in Application Examples 6-8, the rosemary extract, kelp extract and tea extract in the plant extracts of the present invention cooperate with each other and have a synergistic effect in the antioxidant effect.

[0131] Test Example 5 Consumer Sensory Effect Evaluation

[0132] 150 female volunteers aged 30-35 were selected as test subjects and randomly divided into 15 groups, with 10 participants in each group. Test Method: The subjects applied the lipsticks from Application Examples 1-8 and Comparative Application Examples 1-7 to their lips twice daily for 30 consecutive days. Afterwards, the subjects evaluated the moisturizing and lip wrinkle-reducing effects of the lipsticks before and after use, using a 5-point scale: 5 (excellent, very satisfactory); 4 (good, acceptable); 3 (moderately acceptable); and 3 or less (poor, unacceptable). The scores for each group were the average of the 10 participants. The results are shown in Table 7.

[0133] Table 7

[0134] As shown in Table 7, the lip balm disclosed herein achieves a good moisturizing effect through the scientific ratio of various functional ingredients. After adding plant extracts, the effect of reducing lip lines is even better.
