[0034] Examples 1-6 The ingredients and their mass fractions in the functional lipsticks with multiple effects of firming, anti-wrinkle and soothing according to Examples 1-6 of the present invention are shown in Table 1.

[0035] Table 1 Components and their mass fractions in Examples 1-6 The preparation method of the above-mentioned functional lipstick with multiple effects of firming, anti-wrinkle and soothing comprises the following steps: S1. Using methanol as solvent, hexadecyl methacrylate, vinyl-terminated polydimethylsiloxane and sodium methacrylate alginate (hexadecyl methacrylate: vinyl-terminated polydimethylsiloxane: sodium methacrylate alginate = 1.5:1.5:1, m / m / m) were blended, azobisisobutyronitrile (1 wt% of reactant mass) was added, stirred evenly, reacted at 80°C for 6 h under nitrogen, and then filtered, washed and dried to obtain modified polydimethylsiloxane; S2, using ethanol as solvent, mixing hydroxylated silica and caproic acid (hydroxylated silica: caproic acid = 1:3, m / m), reacting under ultrasonication at 70°C for 10 h, then filtering, washing and drying to obtain modified silica; S3.

The intermediate product is injection molded at 80° C., cooled at -10° C. for 10 min, and then molded and demolded to obtain a functional lipstick with multiple effects of firming, anti-wrinkle and soothing.

[0036] Comparative Example 1 A functional lipstick with multiple effects of firming, anti-wrinkle and soothing. The difference between this comparative example and Example 1 is that in step S1, methacrylated sodium alginate is not added. After the preparation is completed, the obtained product is mixed with sodium alginate in a mass ratio of 3:1 to obtain modified polydimethylsiloxane. The remaining ingredients and preparation method are the same as those in Example 1.

[0037] Comparative Example 2 A functional lipstick with multiple effects of firming, anti-wrinkle and soothing. The difference between this comparative example and Example 1 is that the modified silicon dioxide is replaced with commercially available silicon dioxide, and the other ingredients and preparation method are the same as those in Example 1.

[0038] Test Example 1 The moisture retention properties of Examples 1-6 and Comparative Examples 1-2 were tested.

[0039] Test method: 48 women aged between 18 and 48 were randomly selected as subjects and divided into 8 groups, with 6 people in each group. They stayed in a stable environment with a temperature of 20±5°C and a relative humidity of 50±5% during the entire test period. Before the experiment, the ComeometerCM825 measuring instrument produced in Germany was used to test the moisture content of the stratum corneum of the lips before applying lipstick (T0); at the beginning of the experiment, the lips of the subjects were cleaned, lipstick was applied, and after waiting for an appropriate time, the average moisture content (T1) after 1 hour and the average moisture content (T4) after 4 hours of application were tested. Each measurement was performed 3 times, and the average value was taken, and the average water loss rate of each group was calculated. Water loss rate = (T1-T4) / T1×100%; the smaller the water loss value, the better the lip skin barrier, indicating that the product has a better water-locking effect.

[0040] The experimental test results are shown in Table 2.

[0041] Table 2 Moisture retention test results of Examples 1-6 and Comparative Examples 1-2 It can be seen from the above test results that Examples 1-6 of the present invention can significantly increase the water content of the lip skin after use, and the water loss value is relatively small, achieving a significant moisturizing effect. However, in Comparative Example 1, hexadecyl methacrylate, a copolymer of vinyl-terminated polydimethylsiloxane and sodium alginate are physically blended to prepare modified polydimethylsiloxane, and in Comparative Example 2, modified silicon dioxide is replaced with commercially available silicon dioxide. The compatibility between components, the dispersibility and stability of active ingredients are relatively poor, and the improvement of the moisturizing performance of functional lipsticks is not as good as that of the present invention.

[0042] Test Example 2 The anti-wrinkle effects of Examples 1-6 and Comparative Examples 1-2 were tested.

[0043] Test method: 60 healthy female subjects aged between 30 and 60 were randomly selected (divided into 6 groups, 10 in each group). They all had the habit of using lipstick and had visible wrinkles or fine lines on their lips. The female subjects used the functional lipsticks of Examples 1-6 and Comparative Examples 1-2 once a day in the morning and evening for 4 weeks. No other brands of lipstick were used during the test. The test was conducted once at 0, 1, 2, 3 and 4 weeks respectively. Before each test, the subjects were required to clean their lips with clean water, dry their lips with sterile paper towels, sit and rest for at least 0.5 h in an environment with a temperature of about 20°C and a relative humidity of about 50%, and then be measured by professionals.

[0044] (1) The skin elasticity tester (Courage+Khazaka, Germany, model: MPA580) was used to measure the lip skin. The values ​​of the skin elasticity parameter R5 (the closer the value is to 1, the better the skin elasticity) and the firmness parameter F4 (the smaller the value, the firmer the skin) were used as evaluation indicators to evaluate the effect of functional lipstick on improving the elasticity of the lip skin. The lip skin was measured three times each and the average value was calculated. The test results are shown in Table 3.

[0045] (2) The lip skin of the female subjects was photographed using a facial image analyzer (Courage+Khazaka, Germany, model: Visioface), and the wrinkle visualization coefficient reduction rate (%) was calculated to evaluate the improvement of lip wrinkles before and after using functional lipstick. The test results are shown in Table 4.

[0046] Table 3 Skin elasticity measurement results Table 4 Improvement of skin wrinkles It can be seen from the above test results that after using the functional lipstick prepared in Examples 1-6 for 1, 2, 3, and 4 weeks, the elasticity parameter R5 value of the lip skin showed a gradual upward trend, which indicates that the skin elasticity is getting better and better; the firmness parameter F4 value showed a gradual downward trend, which indicates that the skin firmness is significantly improved; the wrinkle visualization coefficient reduction rate gradually increased, which indicates that the wrinkles on the lip skin of the subject are significantly reduced and the skin texture is significantly improved. However, the compatibility between components, the dispersibility and stability of the active ingredients in Comparative Examples 1-2 are relatively poor, and their improvement in the anti-wrinkle effect of the functional lipstick is not as good as that of the present invention.

[0047] The above results indicate that the functional lipstick of the present invention contains multiple active ingredients, has multiple beauty and skin care effects, has a synergistic anti-wrinkle effect on skin wrinkles, can promote skin cell metabolism, reduce wrinkles, and make the lip skin elastic and moisturized.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0049] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
