TABLE 5 test results of appearance and other properties of sunscreen compositions prepared in application examples 1-9 and comparative examples 1-6

As can be seen from the data in Table 5, the sunscreen compositions prepared in examples 1-7 were used in sunscreen creams of examples 1-9, which were fine, uniform, cold and heat resistant, and free of off-flavors; comparative examples 1-6 the sunscreen makeup creams prepared according to comparative examples 1-6 have fine, uniform and consistent paste, no peculiar smell, and good cold resistance and heat resistance.

TABLE 6 test results of properties such as colony content of sunscreen makeup creams prepared in application examples 1-9 and comparative examples 1-6

As can be seen from the data in Table 6, the heavy metal contents of the barrier creams prepared in the examples and the comparative examples meet the requirements of technical specifications for cosmetic safety (2015), and the barrier creams have good antibacterial property and long shelf life.

Secondly, sun protection durability detection: the sunscreen makeup bases prepared in the same mass application examples 1 to 9 and the comparative examples 1 to 6 were uniformly applied to the backs of hands, the sunscreen effect of the sunscreen makeup bases was measured with an SPF measuring instrument and recorded as 0-SPF, the backs of hands were put into clear water for 5 seconds each time, the sunscreen factor of the backs of hands was recorded as 1-SPF after 3 times of putting into clear water, the operation of putting the backs of hands into clear water was repeated 3 times every 30 minutes for 5 seconds each time, the sunscreen factor of the backs of hands was measured after 1 hour and recorded as 2-SPF, the sunscreen factor of the backs of hands was measured after 2 hours and recorded as 3-SPF, and the measurement results were recorded in table 7.

TABLE 7 sunscreen durability test for sunscreen creams prepared in application examples 1-9 and comparative examples 1-6

As can be seen from the data in table 7, the sunscreen compositions prepared from the sunscreen compositions of examples 1 to 7, that is, application examples 1 to 9, have high initial sunscreen index, and after being slightly stirred in clear water, the sunscreen index is not significantly reduced, after 1 hour, the sunscreen index can still reach more than 25.4, and after 2 hours, the sunscreen index is more than 24.2, which indicates that the sunscreen compositions prepared from examples 1 to 7 of the present invention have good waterproof effect and sunscreen durability.

Comparative example 1 since peanut extract was not added to the raw materials, it can be seen from the data in table 7 that the sunscreen composition prepared in comparative example 1 was made into sunscreen cream, the waterproof effect was reduced, the sunscreen index was only 15.2 after 2 hours, and the sunscreen durability was poor.

Comparative example 2 because the peanut extract is not added with the butyrospermum parkii kernel powder and the fennel extract, after the sunscreen composition in the comparative example 2 is prepared into the sun screen, the initial value of the sun protection coefficient is 28.5, and the sun protection index is high, but after the sunscreen composition is soaked and cleaned in clear water, the sun protection index is obviously reduced, and after 2 hours, the sun protection index is only 16.7, and the sun protection durability is poor.

Comparative example 3 a sunscreen lotion of comparative example 3, prepared without the addition of ethylhexyl methoxycinnamate, niacinamide, and ethylhexyl salicylate, had an initial sun protection index of 20.3 and a sun protection index of 16.5 after 2 hours, although the sun protection index was somewhat, but the reduction was not particularly significant.

In the comparative example 4, because the modified attapulgite is not added in the film forming agent, the sun protection index of the sun protection sun screen cream is reduced quickly, the waterproof effect is poor, the sun protection index after 2 hours is only 15.6, and the sun protection durability is poor.

The sunscreen composition prepared in comparative example 5, when prepared into sunscreen makeup cream, had a higher initial sun protection index, but the sun protection index decreased faster, with only 15.8 after 2 hours, and the sun protection durability was poor.

Comparative example 6 is a sunscreen composition prepared in the prior art, and after the sunscreen makeup cream prepared by adding the other cosmetic adjuvants used in application example 1, the sunscreen makeup cream has a high initial sunscreen value but a poor persistence.

And thirdly, detecting the anti-wrinkle and moisturizing effects of the sunscreen composition:

1. and (3) detecting the moisturizing effect: the sunscreen compositions prepared in the comparative examples 7-10 are prepared into sunscreen isolation creams according to the raw material ratio of the sunscreen composition in the application example 1 and other cosmetic auxiliary materials, the sunscreen isolation creams are marked as the control examples 7-10, 70 women of 30-40 years old are randomly selected as observed persons, the observed persons are randomly divided into 15 groups, 10 persons in each group, 1-15 groups of the observed persons correspondingly use the sunscreen isolation creams prepared in the application examples 1-9 and the control examples 7-10, the sunscreen isolation creams are used in the morning every day with the dosage of 3g, the sunscreen isolation creams are evenly applied to the face, after 1 month of continuous use, the skin moisture content of each observed person before and after use is detected by using a skin moisture tester (Corneometer, C + K, Germany), the detection results of 10 persons are averaged, the results are shown in Table 8;

2. and (3) anti-wrinkle effect detection: application examples 7 to 9 prepared from the sunscreen compositions prepared in examples 5 to 7 to which moisturizers and anti-wrinkle Skin care agents were added were prepared, 150 subjects with an average age of 35 to 45 years were selected, and were randomly divided into 15 groups of 10 persons, the test sites were applied 1 time each day in the morning and at the evening at a distance of 10 cm from the base of the palm on the inner side of the arm of the subject, 3g of each time was applied for 8 weeks, the change in the texture of the test sites before and after use was measured using a Skin image analysis system (Skin visualizer SV600), and the change in the elasticity value of the test sites was measured using a Skin elasticity tester (Skin elasticity tester dual MPA 580).

TABLE 8 moisturizing and wrinkle-reducing effects of sunscreen lotions prepared in application examples 7-9 and comparative examples 7-10

As can be seen from the data in table 8, after the sunscreen composition prepared according to the methods in examples 5 to 7 is mixed with other cosmetic adjuvants to prepare sunscreen cream, and the sunscreen cream is applied for one month, the moisturizing effect is good, the skin elasticity is increased, and the texture degree is reduced, which indicates that the sunscreen composition prepared according to examples 5 to 7 has better effects of improving the skin elasticity and texture of human bodies, and can resist wrinkle, moisturize and moisturize.

Comparative examples 7 to 10, after being applied to the skin of a subject, showed insignificant increase in moisture content, inferior moisturizing and moisturizing effects to those of examples 5 to 7 of the present invention, and small change in skin texture, insignificant increase in elasticity, indicating that addition of white tea extract, malachite stock solution and hydrolyzed hyaluronic acid to the moisturizer, and addition of white willow bark extract, iris tectorum root extract, dextran and anthocyanidin to the anti-wrinkle skin care agent can effectively enhance the moisturizing and moisturizing effects of the sunscreen composition, improve skin elasticity and texture state, and have superior anti-aging effects.
