When preparing the above composition, if the raw materials of the composition do not contain a specific raw material, it means that the raw material is not added in the preparation steps involved during its preparation.

[0049] (2) Composition performance test

[0050] 1. Stability: Zeta potential test

[0051] The above composition was diluted 20-fold with a 20% ethanol aqueous solution, stirred at 35°C and 200 rpm for 20 minutes, cooled to room temperature, and allowed to age for half an hour. The zeta potential of each dilution was measured. After standing at room temperature for one week, the zeta potential of each dilution was measured again. A higher absolute value indicates greater stability. The test results are shown in Table 3.

[0054] 2. Anti-aging: ABTS free radical scavenging ability test

[0055] ABTS was prepared into a 2 mmol / L solution using deionized water. 50 mL of this solution was mixed with 200 mL of a 70 mmol / L aqueous solution of K2S2O8 and allowed to stand in the dark for 10 hours to obtain the ABTS solution. The ABTS solution was diluted with a pH 6.5 phosphate buffer (a mixture of 0.2 mol / L NaH2PO4 and 0.2 mol / L Na2HPO4) to an absorbance of 1 at 734 nm to obtain a working solution. 1 mL of the sample solution (the above composition was diluted to a mass concentration of 2% using 30% ethanol) was added to 2 mL of the working solution and mixed to obtain the experimental solution. The solution was allowed to stand for 15 minutes and the absorbance at 734 nm was measured using a spectrophotometer, denoted as A. The ABTS free radical scavenging rate was calculated as (A0 - A0) / A0 × 100%, where A0 is the absorbance of the working solution and A is the absorbance of the experimental solution. The test results are shown in Table 4.

[0056] Table 4: ABTS free radical scavenging rate

[0057] test ABST clearance rate / % Composition 1 86.02 Composition 2 84.97 Composition 7 78.65 Composition 8 76.48 Composition 9 83.81 Composition 10 82.17

[0058] As shown in Tables 3-4, the composition prepared by the present invention exhibits excellent stability and free radical scavenging effects. The zeta potential of the diluted solution reached -39.16 mV, and after one week, it reached -35.23 mV, demonstrating its stability. Furthermore, after dilution to 2%, it scavenged 86.02% of ABST free radicals, effectively combating skin aging.

[0059] According to the tests on compositions 1, 3-6, it can be seen that in the system of the present invention, the use of lauryl PEG-10 tris(trimethylsiloxy)silylethyl polydimethicone and polyglyceryl-2 triisostearate can effectively stabilize the composition. The combination of the two produces a complex effect, and the stability is better when the ratio is 1:0.4-0.7.

[0060] According to the tests on compositions 1 and 11-12, the acrylates / polytrimethylsiloxane methacrylate copolymer promotes the stability of the composition, while trimethylsiloxysilicate, also a film-forming agent, has a negative effect on the stability of the composition.

[0061] According to the tests on compositions 1, 7-10, the alpine edelweiss flower / leaf extract and the alfalfa extract can effectively enhance the free radical scavenging effect of the composition, giving the composition an excellent effect of increasing the skin's anti-aging effect. The two can synergistically enhance the scavenging of ABST free radicals, and the effect produced by the mass ratio of the two is 1:0.8-1.5, which will be better.

[0062] (3) Preparation of liquid foundation

[0063] The raw materials and amounts used in preparing the foundations are shown in Table 5, with the amounts measured in mass percentage. The composition used in Foundations 1 and 4 was Composition 1, the composition used in Foundation 2 was Composition 2, and the composition used in Foundation 5 was Composition 11.

[0064] Table 5: Liquid foundation composition

[0065]

[0066]

[0067] The liquid foundation is prepared as follows: water is added to a container and heated to 70° C., ethylhexyl methoxycinnamate, diethylaminohydroxybenzoyl hexyl benzoate, phenylbenzimidazole sulfonic acid, titanium dioxide, HDI / trimethylol hexyl lactone crosspolymer, silica, disteardimonium hectorite, and sodium chloride are added, and the mixture is stirred at 80 rpm for 0.8 hour. The mixture is cooled to 50° C., the remaining raw materials are added, stirring is continued for 0.5 hour, the mixture is allowed to stand for 2 hours, sterilized, canned, and quality tested to obtain the liquid foundation.

[0068] (IV) Liquid foundation performance test

[0069] The aforementioned liquid foundations were scored, with each criterion scored with a maximum of 10 and a minimum of 0. The sum of the scores for each criterion was used for evaluation. The specific testing method involved selecting 50 volunteers, with 5 males and 5 females randomly assigned to each group, for a total of 10 participants. Each group applied the aforementioned liquid foundation to their faces and rated their use after 10 hours. The sum of the scores for each criterion was calculated (with a maximum of 100 and a minimum of 0). The results are shown in Table 6.

[0070] Table 6: Liquid foundation performance test

[0072] According to the test results in Table 6, the total scores of the liquid foundation prepared by the present invention for makeup holding ability, sun protection, spreadability, and oil absorption effect are 94.7 points, 95.3 points, 95.8 points, and 91.2 points, respectively. It has excellent makeup holding ability, sun protection, uniform spreadability, and oil absorption effects, and has good application prospects.

[0073] Liquid foundation 3 does not use the composition, and the resulting liquid foundation has reduced makeup holding ability, sun protection, spreadability, and oil absorption effects. The reason is that the composition contains lauryl PEG-10 tris(trimethylsiloxy)silylethyl polydimethicone and polyglyceryl-2 triisostearate, which have emulsifying and dispersing active ingredients, and film-forming ingredients trimethylsiloxysilicate and acrylates / polytrimethylsiloxane methacrylate copolymer, which affect the makeup holding effect and spreadability of the liquid foundation. In addition, the above ingredients increase the dispersion of the active ingredients of the liquid foundation, thereby enhancing the sun protection and oil absorption and control properties.

[0074] Liquid foundation 4 does not use sunscreen ingredients, and the resulting liquid foundation has a very poor sun protection effect. It also does not contain titanium dioxide, which can control oil and absorb grease and has a certain filling effect, thereby reducing the makeup holding and oil absorption effects of the liquid foundation to a certain extent.

[0075] Liquid Foundation 5 does not contain the film-forming component acrylic acid (ester) / polytrimethylsiloxane methacrylate copolymer, which has a significant impact on the makeup lasting effect.

[0076] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
