DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be described clearly and completely below. If the specific conditions are not specified in the embodiments, they are carried out according to conventional conditions or conditions recommended by the manufacturer. If the manufacturer of the reagents or instruments used is not specified, they are all conventional products that can be purchased commercially.

[0032] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0033] The embodiment of the present invention provides a makeup setting cream, the components of which, measured by mass percentage, include:

[0034] 3.0-20% diisostearyl malate, 0.5-8.0% microcrystalline wax, 0.5-5.0% petrolatum, 0.1-3.0% squalane, 0.1-5.0% pentaerythritol tetraisostearate, 30-60% polydimethicone, 3-6% polymethylsilsesquioxane, 15-40% modified silica, 3-15% vinyl dimethicone / polymethylsiloxane silsesquioxane crosspolymer and 3-15% vinyl dimethicone / polydimethicone crosspolymer;

[0035] The modified silica is a porous structure, and its surface is modified by polydimethylsiloxane.

[0036] The functions of the various components in the makeup setting cream provided in the embodiment of the present invention are as follows:

[0037] Diisostearyl malate, which has the function of an emollient and is a deep moisturizing oil with a non-greasy texture, improves the adhesion and lubrication effect of the powder composition, and improves the ductility of the paste. Its content needs to be within the range required by the present invention. If the content is too low, the setting cream will be dry, and if the content is too high, the setting cream will be difficult to shape;

[0038] Microcrystalline wax, as a binder and molding agent, makes the powdered substances in the components into a paste, giving the makeup setting cream a paste-like appearance. Its content needs to be within the range required by the present invention. If the content is too low, the product will not be easy to form a paste. If the content is too high, the product texture will be too hard, the feel will be poor and it will be difficult to apply makeup.

[0039] Petrolatum, as an emollient, adhesive, and molding agent, makes the powdered substances in the components into a paste. Although it has similar functions to microcrystalline wax, it is softer and more moisturizing than microcrystalline wax. Using it in combination with microcrystalline wax can make the softness and hardness of the makeup setting cream reach the best state. Its content needs to be within the range required by the present invention. If the content is too low, the product will be easy to crack, and if the content is too high, the product will be too greasy and have a poor feel.

[0040] Squalane, which acts as an emollient, is a moisturizing oil with a non-greasy texture. It improves the adhesion and lubrication effect of powdery substances and improves ductility.

[0041] Pentaerythritol tetraisostearate has the function of an emollient and is a moderately moisturizing oil with a non-greasy texture. It improves the adhesion and lubrication effect of powdery substances and improves ductility. Its content needs to be within the range required by the present invention. If the content is too low, the product is too dry, and if the content is too high, the product cannot be packaged as a cream.

[0042] Polydimethylsiloxane has the functions of an emollient and a skin feel improver, has a film-forming effect, enhances the setting effect of powders, and provides a smooth texture to the product. It is very refreshing and silky, giving the product a velvety texture. Its content needs to be within the range required by the present invention. If the content is too little, the product is too dry and the product texture is not smooth enough. If the content is too high, the product cannot be packaged as a cream.

[0043] Polymethylsilsesquioxane has a smooth skin feel and its raw material is usually in powder form with an average particle size of 7 microns, which can fill fine lines and remove wrinkles, so it has a soft light wrinkle removal effect. Its content needs to be within the range required by the present invention. If the content is too little, the effect of covering wrinkles cannot be achieved. If the content is too much, the covering power is too strong, and it is easy to cause powder to stick and affect the makeup effect.

[0044] Modified silica, due to its porous structure, has a good oil absorption and oil control effect; its surface is modified with polydimethylsiloxane, which is waterproof and drought-resistant, and has a better makeup holding effect. Its content needs to be within the range required by the present invention. If the content is too little, the oil control effect cannot be achieved. If the content is too much, the oil control is too strong, the product will be dry, and the use experience is not good.

[0045] Vinyl dimethicone / methicone silsesquioxane cross-linked polymer makes the makeup matte, and at the same time, it has good skin smoothness and elasticity. Its content needs to be within the range required by the present invention. If the content is too little, the matte effect cannot be achieved. If the content is too high, the product will have a high matte degree, the makeup effect will be dull, and the overall makeup effect will be affected.

[0046] Vinyl dimethicone / dimethicone cross-linked polymer, adhesive, stabilizer, skin feel regulator, provides the product with a silky, velvety texture, and can also give the product a powdery texture. Its content needs to be within the range required by the present invention. If the content is too little, it cannot stabilize the system and the product will have oil problems. If the content is too much, the product cannot be paste-like and the cost will also increase.

[0047] The setting cream provided by the embodiment of the present invention has the above ingredients combined in a suitable ratio, so that the setting cream provided by the present invention is easy to mix evenly during the preparation process, easy to present a paste, and the prepared product is not greasy, the product texture is smooth and easy to apply, and the problem of taking away the base makeup during the setting process can be well avoided, and the effect of long-lasting setting and oil control can be achieved. It should be noted that although some of the components have the same or similar functions, their mechanism of action is not the same after they are actually used on the face, so a better effect can be achieved by using them in combination. If they are replaced with each other, it is difficult to achieve the best setting effect.

[0048] Optionally, the preparation method of modified silica is:

[0049] The natural silicon ore is made into silicon powder, which is then hydrolyzed to obtain silicic acid. The silicic acid is subjected to polycondensation to obtain hydroxyl-containing silicon nano-cores, which are treated by micellization to obtain silicon dioxide microspheres, which are then calcined at high temperature to obtain porous silicon dioxide.

[0050] The porous silica and polydimethylsiloxane are mixed by high-speed stirring and grinding in a mass ratio of 97:3, so that the polydimethylsiloxane is adsorbed on the surface of the porous silica.

[0051] Optionally, the makeup setting cream also includes 0.0001-0.003% astaxanthin. Astaxanthin has an antioxidant effect and can act as a skin protectant.

[0052] Optionally, the composition of the makeup setting cream also includes 0.05-1.0% tocopherol acetate. Tocopherol acetate can act as an antioxidant and skin conditioner, and can further enhance the use experience of the makeup setting cream.

[0053] Optionally, the makeup setting cream also includes 0.1-1.0% of cetyl-PG hydroxyethyl palmitamide, which can act as a skin protectant and has a good moisturizing and emollient effect.

[0054] Optionally, the composition of the makeup setting cream also includes 0.2-1.3% of preservatives. The addition of preservatives can extend the service life of the makeup setting cream.

[0055] Optionally, the preservative includes 0.1-0.8% phenoxyethanol and 0.1-0.5% ethylhexylglycerin.

[0056] Optionally, the composition of the makeup setting cream also includes 0.01-0.1% of a colorant, which gives the makeup setting cream different colors to suit people with different skin colors.

[0057] Optionally, the composition also includes 0.01-0.05% of plant essential oil. Plant essential oil can be used as an emollient and has a pleasant aroma, which makes the product have a special smell to enhance the use experience.

[0058] The embodiment of the present invention also provides a method for preparing a makeup setting cream, comprising:

[0059] The components are mixed evenly at 60-110°C to obtain a mixture, and then the mixture is placed in a carrier plate and cooled to form a single-stage molding;

[0060] After the primary molding, oil-absorbing paper is placed on the surface of the material body for pressing and secondary molding. The number of times of placing the oil-absorbing paper for pressing and secondary molding is at least once, until the surface of the obtained material body is no longer oily.

[0061] The preparation method of the makeup setting cream provided by the present invention needs to be in a paste-like state as the finished product, and needs to ensure that the paste is not greasy, so the content of liquid components or oily substances therein is not high, and the fluidity of these liquid components and oily substances themselves at room temperature is general, so that the mixture is also difficult to have good fluidity, and thus the components are difficult to mix evenly. Therefore, the present invention can ensure that the components are fully mixed by mixing the various components at high temperature, and the oily substances have better fluidity at high temperature. In order to ensure that the makeup setting cream has better moisturizing and mixing uniformity, the added oil may be slightly more, and in order to avoid the makeup setting cream after molding from being oily, by placing oil-absorbing paper on the paste during the secondary molding pressing, the excess oil in the paste is squeezed out under pressure during the pressing process, and the squeezed oil is absorbed by the oil-absorbing paper, thereby obtaining a makeup setting cream with a non-oily texture and good makeup setting effect, and the pressed paste is firm, stable, and not easy to fall off the carrier plate.

[0062] Optionally, the pressure during pressing is 5-20 MPa. If there is excess grease in the paste, the excess grease can be squeezed out under this pressure, and the pressure can ensure that the paste does not deform, and a paste with good stability can be obtained by pressing.

[0063] Specifically, the preparation method is:

[0064] S1. Divide each component into 4 groups

[0065] A1: astaxanthin, microcrystalline wax, petrolatum, squalane, tocopheryl acetate, cetyl-PG hydroxyethyl palmitamide, pentaerythrityl tetraisostearate, dimethicone and pigment;

[0066] A2: Polymethylsilsesquioxane, modified silica, vinyl dimethicone / methicone silsesquioxane crosspolymer, and vinyl dimethicone / dimethicone crosspolymer;

[0067] A3: preservatives;

[0068] A4: Plant essential oils.

[0069] S2. Place component A1 in a mixing container, and heat to 90-110° C. (e.g., 90° C., 95° C., 100° C., or 110° C.) while stirring at a speed of 10-80 rpm (e.g., 10 rpm, 20 rpm, 40 rpm, 60 rpm, or 80 rpm).

[0070] S3, add A2 component to the mixing container, stir at a speed of 10 to 80 rpm (e.g., 10 rpm, 20 rpm, 40 rpm, 60 rpm or 80 rpm) while maintaining the temperature at 90 to 110 ° C (e.g., 90 ° C, 95 ° C or 100 ° C or 110 ° C) and mix for 10 to 90 min (e.g., 10 min, 20 min, 30 min, 50 min, 70 min or 90 min).

[0071] S4. When the temperature of the mixing container is reduced to 75-85°C (e.g., 75°C, 80°C or 85°C), component A3 is added to the mixing container, and the temperature is continued to be reduced to 60-70°C (e.g., 60°C, 65°C or 70°C) while stirring at a rotation speed of 10-80rpm (e.g., 10rpm, 20rpm, 40rpm, 60rpm or 80rpm), and component A4 is added to the mixing container and stirred at a rotation speed of 10-80rpm (e.g., 10rpm, 20rpm, 40rpm, 60rpm or 80rpm) for 10-80min (e.g., 10min, 20min, 30min, 50min, 70min or 80min) to obtain the mixed material.

[0072] S5. Put the mixture into a canning barrel with heating and heat preservation function at a temperature of 60-70°C (e.g. 60°C, 65°C or 70°C), put the mixture into a supporting plate at 60-70°C (e.g. 60°C, 65°C or 70°C), shake the supporting plate gently to evenly disperse the mixture in the supporting plate, and cool it once to form.

[0073] Based on the characteristics of each raw material, the mixing process adopts step-by-step mixing, and each mixing step uses a different temperature to ensure that the raw materials can be dispersed more evenly with each other, avoiding problems such as uneven mixing of raw materials or discoloration and taste change of oil raw materials.

[0074] S6. Place oil-absorbing paper on the surface of the once-molded material, and perform secondary molding at a pressure of 5 to 20 MPa (for example, 5 MPa, 10 MPa, 15 MPa or 20 MPa). If the surface of the material is matte, do not repeat the secondary molding operation. If the surface of the material is still oily, place oil-absorbing paper again for pressing, and repeat the above operation until the surface of the material is matte.

[0075] The present invention is specifically described below in conjunction with a plurality of embodiments and comparative examples, and the formulations of each embodiment and comparative example are as follows:

[0076] Table 1 Group distribution ratio of each embodiment

[0077]

[0078]

[0079] Table 2 Group distribution ratio of each comparative example

[0080]

[0081]

[0082] Table 3 Group distribution ratio of each comparative example

[0083]

[0084] The preparation methods of the various embodiments and comparative examples in Tables 1 to 3 are as follows:

[0085] Place component A1 in an oil phase pot and heat to 100°C at 20 rpm while stirring.

[0086] Add component A2 into the oil phase pot, and stir at a speed of 30 rpm while maintaining the temperature at 100° C. for 10 minutes.

[0087] When the temperature of the oil phase pot is reduced to 80° C., component A3 is added to the oil phase pot, and the temperature is further reduced to 65° C. while stirring at a speed of 40 rpm. Component A4 is added to the oil phase pot and stirred for 10 minutes to obtain the mixture.

[0088] The total stirring time in the oil phase pot was 15 min.

[0089] The mixed material is loaded into a canning barrel with heating and heat preservation function at a temperature of 65°C, and then loaded into a carrying plate at 65°C. The carrying plate is gently shaken to evenly disperse the mixed material in the carrying plate.

[0090] After the mixture in the supporting plate is cooled to room temperature, oil-absorbing paper is placed on the surface of the material and pressed once at a pressure of 10 MPa. In Comparative Examples 1 and 8, since less or no microcrystalline wax is used, the viscosity is low, resulting in deformation of the paste during the pressing process. The surfaces of the materials in other embodiments and comparative examples are matte after pressing.

[0091] Since Comparative Example 1 and Comparative Example 8 cannot be formed by pressing, in subsequent tests, the products of Comparative Example 1 and Comparative Example 8 tested were all tested using products that were cooled but not pressed.

[0092] Example 7

[0093] The components of this embodiment are the same as those of embodiment 6, except that:

[0094] All components were added into the oil phase pot at the same time and mixed at 100°C and 30 rpm for 15 min.

[0095] Example 8

[0096] The components of this embodiment are the same as those of embodiment 6, except that:

[0097] All components were added into the oil phase pot at the same time and mixed at 80°C and 30 rpm for 15 min.

[0098] Comparative Example 13

[0099] The components of this comparative example are the same as those of Example 6, except that the components are mixed at room temperature. The stirring speed during the mixing process is 30 rpm, and the total stirring time is 20 min.

[0100] Comparative Example 14

[0101] This comparative example is basically the same as Example 6, except that the material body is not covered with oil-absorbing paper during the pressing process.

[0102] Experimental Example 1

[0103] Volunteers were recruited to try out the performance of the makeup setting cream prepared in Example 6, and the makeup setting effect was evaluated after the trial. The number of volunteers was 30.

[0104] Volunteer requirements: Women aged 18 to 40 with good skin condition and who usually wear makeup.

[0105] The evaluation indicators are:

[0107] After using sweat to rinse, the base makeup in the product area will not be dull;

[0108] After washing with sweat, the base makeup in the product area will not float;

[0109] The makeup on the product area will not come off after washing with sweat;

[0110] The product has an anti-sweat effect after use.

[0111] Scoring criteria:

[0112] 5-point scale: 1 represents strongly disagree, 2 represents disagree, 3 represents somewhat agree, 4 represents agree, and 5 represents strongly agree.

[0113] The number of people with a statistical score of 23 points is valid, and the degree of agreement is calculated as follows: Degree of agreement = [(number of people scoring 3 points (somewhat agree) + number of people scoring 4 points (agree) + number of people scoring 5 points (strongly agree)) / total number of people] x 100%.

[0114] The trial method is:

[0115] Clean arms and wait: The subjects clean the inner forearms of both hands with clean water, dry the skin and sit quietly in a laboratory at a temperature of 21±1℃ and 50+10%RH for 30 minutes. During this period, the subjects cannot drink water or beverages. The forearms are exposed and placed in the test state, and remain relaxed;

[0116] The experimenter marks a 3cm×3cm test area on the inner side of the subject's forearm. Multiple areas can be marked on the same arm at the same time, with at least 1cm between each test area. Mark two test areas (sample area and control area) on the inner side of the left and right forearms respectively, with the inner side of the right forearm as the waterproof test area and the inner side of the left forearm as the sweat-proof test area;

[0117] Apply samples: The lab technician applies liquid foundation and test sample to the sample area and liquid foundation to the control area.

[0118] The laboratory technician instructed the subjects to rinse the test area with the corresponding simulated sweat at a flow rate of 15ml / s for 1 minute, and then let the arms dry naturally after rinsing. The formula of the simulated sweat refers to the formula disclosed in "GB / T 14576-2009 Textiles - Color Fastness Tests - Light Fastness and Sweat Composite Color Fastness".

[0119] After washing, the subjects filled in the questionnaire.

[0120] The subjects' recognition that the base makeup in the product area is intact after using sweat rinsing is recorded in Table 4, the subjects' recognition that the base makeup in the product area is not dull after using sweat rinsing is recorded in Table 5, the subjects' recognition that the base makeup in the product area is not powdery after using sweat rinsing is recorded in Table 6, the subjects' recognition that the base makeup in the product area does not come off after using sweat rinsing is recorded in Table 7, and the subjects' recognition that the base makeup in the product area is sweat-proof after using sweat rinsing is recorded in Table 8.

As can be seen from the above table, the makeup setting cream provided in Example 6 of the present invention has a 100% recognition rate in terms of complete base makeup, no dullness, no floating powder, no makeup removal, and sweat resistance, which means that the makeup setting cream provided by the present invention has a complete base makeup, no dullness, no floating powder, no makeup removal, and sweat resistance after setting.

[0136] Experimental Example 2

[0137] This experiment tests the oil control effects of the embodiments of the present application and the comparative examples, and compares the embodiments with the corresponding comparative examples to illustrate that each embodiment of the present application has an excellent oil control effect.

[0138] Test method:

[0139] 170 volunteers aged 18 to 45 were selected for a facial trial experiment. The subjects were required to have oily or combination skin. The 170 volunteers were divided into 17 groups, with 10 people in each group. Each volunteer was required to use the same base makeup product (ZiSe Porcelain Glaze Foundation) on the left and right faces after cleansing, and use different setting products to apply makeup. The facial photos were taken with the instrument VISA-7 before, during or after makeup, and the photos were imported into the PIMIA analysis software.

Combined with the embodiments of the aforementioned multiple experimental groups, it also had a better oil control effect, which can illustrate that the makeup setting creams provided by each embodiment of the present invention have a good oil control effect.

[0189] In summary, the setting cream provided in the embodiment of the present invention, the above ingredients are combined in a suitable ratio, so that the setting cream provided by the present invention is easy to mix evenly during the preparation process, easy to present a paste, and the prepared product is not greasy, which can well avoid the problem of taking away the base makeup during the setting process, and can achieve the effect of long-lasting setting and oil control.

[0190] The makeup setting cream provided by the present invention can ensure that the components are fully mixed by mixing the various components at high temperature, and the oily substances have better fluidity at high temperature. In order to ensure that the makeup setting cream has better moisturizing and mixing uniformity, the added oil may be slightly more. In order to avoid the makeup setting cream having an oily texture after molding, oil-absorbing paper is placed on the paste during molding and pressing. During the pressing process, the excess oil in the paste is squeezed out under pressure, and the squeezed oil is absorbed by the oil-absorbing paper, thereby obtaining a makeup setting cream with a non-greasy texture and good makeup setting effect. The pressed paste is firm and stable, and is not easy to fall off the carrier plate.

[0191] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
