The sunscreen sticks prepared in examples 1 to 5 and comparative example 1 were subjected to performance evaluation, which included:

1. stability test

The sunscreen sticks containing water-soluble components prepared in examples 1 to 5 were unscrewed, placed in a-15 ℃, 37 ℃ and 45 ℃ inspection box for 2 months, and the properties of the sunscreen sticks were checked at 30 days and 60 days, and the specific test results are shown in table 1.

As can be seen from Table 1, the sunscreen stick containing water-soluble components prepared according to the invention has no abnormality (maintains solid stick shape, and has no abnormal conditions such as sweating, cracking, skewing and the like) after being placed for 2 months at the temperature of minus 15 ℃ to 45 ℃, and meets the actual use requirements.

2. Sun protection index test

The sunscreen sticks containing water-soluble components prepared in examples 1 to 5 were tested according to the specific requirements of the sun protection index test in the technical specification for cosmetic safety (2015 edition), 10 (5 for each of men and women) volunteers 23 to 58 years old were selected, the light source was a solar simulator xenon arc lamp, the standard control samples were respectively SPF 16.10 ± 2.40 and PFA 4.40 ± 2.40, and the specific test results are shown in table 2.

As can be seen from table 2, the sunscreen bars containing water soluble components prepared according to the present invention all have SPF values greater than 5, meeting the claimed and actual sunscreen requirements. Since the water-soluble sunscreen agent, phenylbenzimidazole sulfonic acid, was contained in example 1, even though the total amount of sunscreen agent contained was less than the total amount of sunscreen agent of example 3 containing no water-soluble sunscreen agent and the total amount of sunscreen agent of comparative example 1 containing no water-soluble component, the SPF value and PFA value of example 1 containing water-soluble sunscreen agent were higher than those of example 3 containing no water-soluble sunscreen agent and comparative example 1 containing no water-soluble component. The synergistic sunscreen effect can be effectively reduced by the synergistic use of the oil-soluble sunscreen agent and the water-soluble sunscreen agent in the sunscreen stick.

3. Safety test

The sunscreen sticks containing water soluble components prepared in examples 1-5 were each subjected to a 48 hour human skin occlusion test. 30 healthy volunteers with the ages of 20-59 are selected, 0.020-0.025g of samples are respectively placed in a spot tester, a special adhesive tape is externally applied to the back of the volunteer, the spot tester is removed after 24 hours, the samples are wiped off, the skin reactions of the volunteer are observed at 0.5 hour, 24 hours and 48 hours respectively, the results are recorded according to the skin reaction grading standard in the technical Specification for cosmetic safety (2015 edition), and the specific results are shown in Table 3.

As can be seen from Table 3, the sunscreen stick containing water-soluble components prepared according to the present invention has no adverse skin reactions in the patch test of human skin, indicating that the sunscreen stick containing water-soluble components prepared according to the present invention does not cause irritation to the skin.

4. Moisture retention test

The sunscreen sticks prepared in example 1 and comparative example 1 were subjected to transdermal water loss and skin moisture tests. The test procedure selects 28 healthy volunteers (male 9, female 19) with the age of 24-46 years, applies two sunscreen sticks to the inner side of the hand with equal area, and then tests the moisture content and transdermal water loss rate of the skin at 0.5, 2, 4, and 8 hours using Delfin S/N MSC 1244 and S/N SWL5260, respectively, the test procedure is carried out in a constant temperature and humidity laboratory, the relative humidity is 30 + -5%, the temperature is 25 + -1 ℃, and the specific results are shown in figure 1 and figure 2.

As can be seen from fig. 1 and 2, the sunscreen stick containing a water-soluble component prepared according to the present invention (example 1) is significantly superior to the sunscreen stick containing no water-soluble component (comparative example 1) in effectively increasing the moisture content of the skin, although it is not much different in preventing the transdermal water loss. The sunscreen stick containing the water-soluble component prepared by the invention can better keep moisture and make skin comfortable compared with the traditional sunscreen stick.

5. Usage sensing test

The sunscreen sticks prepared in example 1 and comparative example 1 were subjected to a feeling of use test. The test process adopts blind test, 28 healthy volunteers (9 men and 19 women) with the ages of 24-46 are selected to participate, the volunteers are required to score two sun-proof bars according to the spreadability, the comfort level after being smeared, the freshness and the humidity preservation respectively, a 5-score scoring standard is adopted, the higher the score is, the higher the preference is represented, and the specific result is shown in figure 3.

As can be seen from fig. 3, the sunscreen stick containing a water-soluble component (example 1) prepared according to the present invention is significantly better than the sunscreen stick containing no water-soluble component (comparative example 1), particularly in terms of freshness, regardless of the spreadability, or the comfort, freshness, and moisture retention after spreading, compared to the sunscreen stick containing no water-soluble component (comparative example 1). It is shown that the sunscreen sticks containing water-soluble components prepared according to the present invention have better feel in use and higher acceptance than conventional sunscreen sticks.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
