[0019] Table 2: Skin feel test scoring details Example 1 A concealer, the raw materials for its preparation, in terms of mass percentage, include the following components: Table 3: Raw materials and amounts used in the preparation of concealer in Example 1 The above-mentioned concealer is prepared by the following preparation method: S1. Add cetyl PEG / PPG-10 / 1 polydimethylsiloxane, PEG-10 polydimethylsiloxane, glycerin, and deionized water into a reactor, heat to 80° C. and keep warm to prepare the aqueous solution; then add dextrin palmitate and phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate into another reactor, heat to 80° C. until transparent, then homogenize with a homogenizer, then slowly add the aqueous solution into the reactor and homogenize with a homogenizer at 3000 rpm / min for 3 min to obtain an emulsion; S2, add synthetic wax, microcrystalline wax, hydrogenated (styrene / methylstyrene / indene) copolymer, liquid paraffin, petrolatum, bis-diglycerol polyacyl adipate-2, and tridecyl trimellitate into the reactor, heat to 110°C until the phase is dissolved, and use it as the oil phase for standby; mix the heated oil phase, methyl methacrylate crosspolymer, vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane crosspolymer, titanium dioxide powder CI77891, and iron oxide powder CI77491, grind them 3 times, and then discharge the mixture to obtain the oil phase; S3. Pour the emulsion obtained in S1 into the oil phase in S2, heat and melt until it is uniform, add the compound of tocopherol acetate, caprylyl glycol and ethylhexylglycerin, stir for 3-5 minutes, discharge the material, pour it into the corresponding packaging material, cool and shape it, match the packaging material and put it on a plate to obtain the concealer.
[0020] Embodiment 2-5 A concealer, the preparation method of which is the same as that of Example 1, the only difference being that the amounts of the components used are different, as shown in the table below.
[0021] Table 4: Raw materials and amounts used in preparing concealer cream in Examples 2-5 Various performance tests were performed on the concealers prepared in Examples 1-6 above. The test results are shown in the table below.
[0022] Table 5: Concealer performance test results obtained in Examples 1-6 Appearance Heat resistant Cold resistant Touch Skin feel Makeup effect Example 1 Meet the requirements No deformation or softening No cracks 9.2 9.6 8.9 Example 2 Meet the requirements No deformation or softening No cracks 7.9 8.8 9.0 Example 3 Meet the requirements No deformation or softening No cracks 8.2 8.1 8.6 Example 4 Meet the requirements No deformation or softening No cracks 8.0 7.5 8.1 Example 5 Meet the requirements No deformation or softening No cracks 8.1 7.4 7.6 Example 6 Meet the requirements No deformation or softening No cracks 6.9 7.2 7.8 From the above test results, it can be seen that the concealer prepared in Examples 1-6 has excellent physical and chemical properties, and can maintain stable properties regardless of whether it is in a hot environment or a cold environment; In addition, in the skin feel test, the touch score was 6.9-9.2 points, the skin feel score was 7.2-9.6 points, and the makeup effect score was 7.8-9.0 points, which shows that the concealer prepared in the above embodiment has a better makeup experience and a special ice cream velvet feel; the various performance test data of Example 1 of the present application performed best among all the embodiments and can be used as the most preferred embodiment.
[0023] It can be seen from the above table that when the amount of dextrin palmitate is reduced, the touch and skin feel scores both decrease slightly. When the amount of deionized water and glycerin is reduced, the touch, skin feel and makeup effect scores all decrease. When the amount of vinyl dimethicone / methicone silsesquioxane crosspolymer and phytosteryl / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate is reduced, the skin feel and makeup effect scores further decrease. Analyzing the reasons, the possible reasons are: Dextrin palmitate has a thickening effect in liquid systems, while synthetic wax used alone mainly has a hardening effect. When dextrin palmitate is added to the system, due to its similarity with wax in functional groups, the similar solubility property will weaken the molding effect of the wax. This property helps to create a skin feel similar to ice cream. Furthermore, by adding an aqueous solution with a slightly higher surface tension, the skin touch experience can be significantly improved. At the same time, with the use of vinyl dimethicone / polymethicone silsesquioxane crosspolymer and phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate, the velvety feel, skin-friendliness and soft skin experience can be enhanced during the makeup and blending process.

[0032] Table 13: Raw materials and amounts used in the preparation of concealer in Comparative Example 8 Various performance tests were performed on the concealers prepared in the above comparative examples 1-8. The test results are shown in the table below.
[0033] Table 14: Concealer performance test results prepared in Examples 1-6 Appearance Heat resistant Cold resistant Touch Skin feel Makeup effect Example 1 Meet the requirements No deformation or softening No cracks 9.2 9.6 8.9 Comparative Example 1 Meet the requirements No deformation or softening There are cracks 7.0 6.2 7.0 Comparative Example 2 Meet the requirements Deformation Softening No cracks 6.5 7.9 7.4 Comparative Example 3 Meet the requirements No deformation or softening No cracks 5.9 7.0 7.1 Comparative Example 4 Meet the requirements No deformation or softening No cracks 7.6 6.5 7.2 Comparative Example 5 Meet the requirements No deformation or softening No cracks 7.3 6.4 7.3 Comparative Example 6 Meet the requirements No deformation or softening No cracks 7.9 8.2 8.0 Comparative Example 7 Meet the requirements No deformation or softening No cracks 7.7 8.1 7.8 Comparative Example 8 Meet the requirements No deformation or softening No cracks 7.5 7.1 7.2 It can be clearly seen from the above comparison table that compared with the concealer prepared in Example 1, the concealers in Comparative Examples 1 to 8 have declined to varying degrees in various performance indicators, especially in Comparative Examples 1 and 2, the stability of the concealers prepared therefrom failed to meet the standard, and the scores in terms of touch, skin feel and makeup effect were significantly lower than those in Example 1. Although the concealer in Comparative Example 3 passed the stability test, its touch score was only 5.9 points, the lowest score among all comparative examples.
[0034] In addition, in Comparative Examples 4 to 8, we tried to replace or directly omit the vinyl dimethicone / methicone silsesquioxane crosspolymer and phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate in the formula in equal amounts. The results showed that these adjustments resulted in a significant decrease in the performance of the concealer in the skin feel performance test, and all failed to reach the level of Example 1. This finding further emphasizes the irreplaceable nature of vinyl dimethicone / methicone silsesquioxane crosspolymer and phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate in the concealer formula, and also reveals the importance of the possibility of their combined use for improving the overall performance of the concealer.
[0035] The above are all modifications without creative contribution or solutions that obviously constitute technical inspiration that can be made to the present embodiment as needed by technical personnel in this field after reading this specification, but they should be protected by patent law as long as they are within the scope of the claims of this application.
