Sort and analyze the measured viscosity values ​​to obtain the viscosity curve and the average value of the viscosity value.

[0090] There is a close connection between the various components in lip glaze. In order to further explore the close relationship between the various components in lip glaze, especially emulsifiers, silicone elastomers and thickeners, the inventors of the present application conducted the following experiments.

[0095] Example 4

[0096] The main difference between Example 4 and Example 1 is that no thickener is added, and an equal amount of emulsifier is used instead.

[0097] Example 5

[0098] Compared with Example 1, Example 5 mainly differs in that the mass ratio of the silicone elastomer, the emulsifier and the thickener is 1:0.08:0.04, and the mass percentage of the silicone elastomer is 30%.

[0099] Example 6

[0101] Test Section

[0102] Weigh equal amounts of the water mist lip glaze prepared in the comparative example, take appropriate amounts of samples, and test their stability. Since the oil-in-water water mist lip glaze needs to be stored for a long time in different environments, and needs to be transported and placed on shelves according to market demand, it is necessary to test its stability at different temperatures and after centrifugation.

[0103] a. Stability test

[0104] Test steps for stability test under high and low temperature environment: Weigh equal amounts of water-in-oil type water mist lip glaze samples prepared in each embodiment and comparative example, and test the stability under high and low temperature environment. This application adopts the following two test methods for testing:

[0105] ① Place the oil-in-water lip glaze sample in an incubator and store it at -15°C, room temperature, and 48°C for 24 hours each. Repeat the cycle three times and observe the sample status.

[0106] ② Place the oil-in-water lip glaze sample in an incubator and store it at -15℃, 5℃, room temperature, 40℃, and 50℃ for 4 weeks respectively, and observe the sample status.

[0107] The test steps of the stability test after centrifugation are as follows: Weigh equal amounts of the oil-in-water type water mist lip glaze samples prepared in the examples and place them in a centrifuge, centrifuge them at 2000 rpm for 30 minutes, take them out, and observe the stratification of the oil-in-water type water mist lip glaze samples. The test results are shown in Table 3.

[0110] Sensory test

[0111] The test randomly selected 36 healthy women aged 18 to 40, and used the same water-in-oil type water mist lip glaze to draw lines on the inside of the left arm (the right arm was a blank control) and lips, and recorded the feeling when the sample was just applied and after the film was formed. According to the evaluation criteria, the average value was obtained. The evaluation criteria are shown in Table 4, and the test results are shown in Table 5.

[0116] From the test results in Table 5, it can be seen that the selection of different silicone elastomers in the emollient has a relatively large impact on the results. The example has good skin feel and film-forming effect. According to the analysis, the silicone elastomer used in the example is a mixture of high molecular weight polydimethylsiloxane cross-linked polymer in polydimethylsiloxane. The non-volatile kinematic viscosity is 5 mm 2 / s~8mm 2 / s, the mass content of silicon powder is 20% to 30% of the first polydimethylsiloxane blend and has a certain volatility and a kinematic viscosity of 1mm 2 / s~2mm 2 / s, the mass content of silica powder is 15-25% of polydimethylsiloxane blend. It has a light texture and good spreadability. It can keep the skin soft and velvety for a long time. At the same time, it has a strong matte effect and strong covering power.

[0117] Compared with the raw materials in Comparative Examples 1 to 3, the embodiments are non-greasy or matte, and have better skin adhesion, better compatibility with other components in the formula, and the material prepared by emulsification is uniform, delicate, light and moist. For other Comparative Examples 1 to 3 with different viscosities of polydimethylsiloxane and silicon powder, the material is relatively rough, has a weaker water feel, and has a poor film-forming effect after emulsification. Even if the raw materials themselves contain film-forming agents, the film-forming properties of the material become worse after emulsification. For example, in Comparative Example 1, polydimethylsiloxane (and) polydimethylsiloxane cross-linked polymer (and) trimethylsiloxysilicate contain film-forming agents, which become rough and greasy after emulsification. The blend of polydimethylsiloxane and polydimethylsiloxane cross-linked polymer is too volatile, and the raw materials are easy to rub into mud. The blend of dimethicone and dimethicone / vinyl dimethicone crosspolymer in Comparative Example 2 has too greasy skin feel and is not matte enough, and the blend of dimethicone and dimethicone crosspolymer also has too greasy skin feel and is not matte enough. The blend of dimethicone, PEG-10 dimethicone / vinyl dimethicone crosspolymer and polymethylsilsesquioxane in Comparative Example 3 contains a film-forming agent and becomes rough after emulsification, is not delicate enough and is greasy.

[0118] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
