Performance test

The lipsticks of examples 1 to 20 and comparative examples 1 to 7 were each used as a sample of a lipstick to be tested.

20 healthy and allergy-free volunteers aged 20-40 years are selected to carry out experiments under the environment of room temperature (23 +/-2) DEG C and humidity of 40-60%. Before the experiment, the volunteer needs to be quiet for 30min in the environment, after the environment is balanced, the upper lip and the lower lip of the test subject are respectively divided into a left part and a right part, the left part of the test subject is a blank control area, and the right part of the test subject is a lipstick sample smearing area to be tested. And uniformly smearing the lipstick sample to be tested on the test part.

1. Lip skin moisture content and rate of change of moisture content

After the test subject uses the lipstick for 2h, 4h and 6h, the moisture content of the experimental part of the test subject before and after using the sample is tested by using a test probe of a Corneometer CM825 skin moisture tester, the average value of 5 times of measurement is taken as a test value, and the moisture content change rate is calculated.

Moisture content change (moisture content after use-moisture content before use)/moisture content before use × 100%

Wherein, the water content before use refers to the water content of lips after 0h, and the water content after use refers to the water content of lips after 2h, 4h and 6h respectively.

2. Water loss rate of lip skin (TEWL)

Subjects measured TEWL changes in the skin of the subjects before and after application of the samples at the test sites using a transepidermal water loss test probe for 20s each time using TewameterTM300 after 2h, 4h, 6h of lipstick application.

TABLE 2 Experimental results on the moisture content and moisture change rate of lip skin

TABLE 3 lip skin Water loss test results

Combining examples 1-3 and comparative example 1 and combining tables 2 and 3, it can be seen that the lip moisture content of the lipstick of examples 1-3 after 2h, 4h and 6h is higher than that of the lipstick of comparative example 1, the moisture content change rate is higher than that of comparative example 1, and the lip skin water loss rate is lower than that of comparative example 1, which shows that the lipstick of the present application has better moisturizing effect than that of the lipstick of comparative example 1.

It can be seen from the combination of example 2 and comparative examples 2 to 3 and from tables 2 and 3 that the moisturizing effect of lipstick can be improved by adding phytosterol ester to lipstick, but the moisturizing effect of lipstick is not improved significantly when the amount of phytosterol ester added exceeds a certain range.

It can be seen from the combination of example 2 and comparative examples 4 to 5 and tables 2 and 3 that the moisturizing effect of lipstick is not greatly affected by methyl ester of hydrogenated rosinate.

As can be seen from the combination of example 2 and comparative examples 6 to 7 and tables 2 and 3, the addition of phytosterol ester to lipstick resulted in better moisturizing effect than glycerin and sodium hyaluronate.

As can be seen by combining examples 2 and 4 to 6 with tables 2 and 3, the moisturizing effect of the lipstick added with β -sitosterol oleate, campesterol oleate, stigmasterol oleate is better than that of the lipstick added with β -sitosterol ferulate, probably because oleic acid is more easily absorbed by the human body.

As can be seen from the combination of example 4 and examples 7 to 10 and tables 2 and 3, the moisturizing effect of lipstick was improved by adding a certain amount of tea seed oil, but the moisturizing effect of lipstick was not remarkably improved when the amount of tea seed oil exceeded a certain range.

It can be seen from the combination of example 4 and examples 11 to 14 and from tables 2 and 3 that the moisturizing effect of lipstick was improved by adding a certain amount of trehalose, but when it exceeded a certain range, the moisturizing effect of lipstick was not significantly improved.

As can be seen by combining example 4 with examples 15 to 17 and combining tables 2 and 3, the moisturizing effect of lipstick can be improved by adding a certain amount of tea seed oil and trehalose. Combining examples 7-14 and examples 15-17 with tables 2 and 3, it can be seen that the simultaneous addition of tea seed oil and trehalose is more effective than the addition of tea seed oil or trehalose alone. Combining example 9 and example 17, combining example 14 and example 18, and combining tables 2 and 3, it can be seen that there is a synergistic compounding effect of tea seed oil and trehalose.

Combining example 4 with examples 19-21, and combining tables 2 and 3, it can be seen that phenoxyethanol and tocopherol have little effect on the moisturizing effect of lipstick.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
