Description

Technical Field

[0001] The present invention is applied to the technical field of cosmetics, and particularly relates to a makeup setting powder cake composition and a preparation method thereof. Background Art

[0002] Makeup setting powder cakes play a crucial role in the beauty makeup process. They are mainly used for makeup setting and touch-up. When used for makeup setting, they can fix the makeup and make the makeup last longer. Moreover, due to their small size and portability, they are very suitable for carrying out for touch-up. However, the effects of existing makeup setting powder cakes vary, and they cannot well combine the effects of long-lasting makeup setting and high-efficiency oil absorption. Therefore, a makeup setting powder cake that can simultaneously achieve long-lasting makeup setting and high-efficiency oil absorption will surely be the direction to lead the breakthrough of the cosmetics industry. Common ordinary powder cakes adsorb oil through silica and increase the covering rate through titanium dioxide. However, a large increase in the content of silica and titanium dioxide will cause caking of powder when oil appears after makeup application and the "fake white" effect during powder cake makeup application, failing to achieve the effect of invisible base makeup.

[0003] Therefore, there is a need for a makeup setting powder cake with long-lasting makeup setting, rapid oil absorption and no powdery feeling and a preparation method thereof to solve the deficiencies of the existing technology. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the existing technology and provide a makeup setting powder cake composition with long-lasting makeup setting, rapid oil absorption and no powdery feeling and a preparation method thereof.

[0005] The technical solution adopted by the present invention is that the makeup setting powder cake composition includes the following components: by mass percentage, vinyl dimethicone / methicone silsesquioxane crosspolymer 50 - 70%, isononyl isononanoate 20 - 40%, dimethicone 2 - 5%, dibutyl isooctanoyl glutamine 0.4 - 1.2%, dibutyl lauroyl glutamine 0.4 - 1.2%, caprylyl glycol 0.36 - 0.9%, ethylhexylglycerin 0.04 - 0.1%, phenoxyethanol 0.4 - 1%.

[0006] As can be seen from the above solution, by using vinyl dimethicone / methicone silsesquioxane crosspolymer instead of silica, the oil absorption rate and long-lasting makeup holding effect are effectively improved. In addition, without titanium dioxide in the composition, the soft focus effect can be improved and the covering rate can be increased, and fine lines can be effectively covered. The combination of isononyl isononanoate, dibutyl isooctanoyl glutamine and dibutyl lauroyl glutamine increases the hardness of the powder polymer, making the makeup application more convenient. The skin feeling during use is more refreshing and non-greasy, and there is a skin moisturizing effect. In addition, the prepared makeup setting powder cake composition has no base color. Thus, the problems of "oily face", "fake white" and "caking of powder" that occur in common makeup setting powder cake compositions are solved, and the effects of oil absorption without absorbing makeup, invisible makeup setting and skin moisturizing are achieved.

[0007] One preferred solution is that the vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer is hollow spherical.

[0008] One preferred solution is that the ratio of isononyl isononanoate, dibutyl isooctanoyl glutamine, and dibutyl lauroyl glutamine is 90 - 96%: 2 - 5%: 2 - 5%.

[0009] One preferred solution is that the setting powder cake composition comprises the following specific components: by mass percentage, vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer 57%, isononyl isononanoate 35.5%, polydimethylsiloxane 4.5%, dibutyl isooctanoyl glutamine 0.6%, dibutyl lauroyl glutamine 0.6%, caprylyl glycol 0.81%, ethylhexylglycerin 0.09%, phenoxyethanol 0.9%.

[0010] One preferred solution is that the setting powder cake composition comprises the following specific components: by mass percentage, vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer 56%, isononyl isononanoate 38%, polydimethylsiloxane 3%, dibutyl isooctanoyl glutamine 0.8%, dibutyl lauroyl glutamine 0.8%, caprylyl glycol 0.63%, ethylhexylglycerin 0.07%, phenoxyethanol 0.7%.

[0011] One preferred solution is that the setting powder cake composition comprises the following specific components: by mass percentage, vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer 60%, isononyl isononanoate 32%, polydimethylsiloxane 4.6%, dibutyl isooctanoyl glutamine 1.2%, dibutyl lauroyl glutamine 1.2%, caprylyl glycol 0.45%, ethylhexylglycerin 0.05%, phenoxyethanol 0.5%.

[0012] The preparation method of the setting powder cake composition comprises the following steps: Step S1, weigh isononyl isononanoate, dibutyl isooctanoyl glutamine, and dibutyl lauroyl glutamine and mix them into a liquid mixture, heat the liquid mixture, the heating temperature is 210°C, stir the liquid mixture while heating until dibutyl isooctanoyl glutamine and dibutyl lauroyl glutamine are completely dissolved and become transparent, and leave the dissolved liquid mixture for standby; Step S2, weigh polydimethylsiloxane and vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer and mix them into a powder mixture and stir evenly; Step S3: Add the powder mixture into the liquid mixture, then stir the mixed composition until it becomes semi-transparent. Then weigh caprylyl glycol, ethylhexylglycerin, and phenoxyethanol, add them into the composition, stir well, and set aside for later use. Step S4: Uniformly fill the stock prepared in Step S3 into a container. Place the container in a powder pressing mold, use elastic cloth as the powder pressing medium, and press it twice at a pressure of 80 ± 20 kg / cm² to obtain a semi-transparent makeup powder cake composition.

[0013] In a preferred embodiment, during the two pressings, the first pressure holding time is 2 s and the second pressure holding time is 1 s. Description of the Drawings

[0014] Figure 1 is a physical product diagram of the makeup powder cake composition. Detailed Embodiments

[0015] The makeup powder cake composition comprises the following components: by mass percentage, vinyl dimethicone / polymethylsiloxane sesquisiloxane cross-linked polymer 50 - 70%, isononyl isononanoate 20 - 40%, polydimethylsiloxane 2 - 5%, dibutyl isooctanoylglutamine 0.4 - 1.2%, dibutyl lauroylglutamine 0.4 - 1.2%, caprylyl glycol 0.36 - 0.9%, ethylhexylglycerin 0.04 - 0.1%, phenoxyethanol 0.4 - 1%. The vinyl dimethicone / polymethylsiloxane sesquisiloxane cross-linked polymer is in the shape of a hollow sphere.

[0016] The ratio among isononyl isononanoate, dibutyl isooctanoylglutamine, and dibutyl lauroylglutamine is 90 - 96%: 2 - 5%: 2 - 5%. If the contents of dibutyl isooctanoylglutamine and dibutyl lauroylglutamine are too high, it will be difficult to dissolve the stock, and the stock will solidify too quickly after dissolution, making it difficult to stir evenly after adding vinyl dimethicone / polymethylsiloxane sesquisiloxane cross-linked polymer later; while if the contents are too low, the stock will be too thin, and after adding vinyl dimethicone / polymethylsiloxane sesquisiloxane cross-linked polymer finally, it will be difficult to press the powder into a shape, ultimately making the powder cake difficult to use. By adopting the ratio of isononyl isononanoate, dibutyl isooctanoylglutamine, and dibutyl lauroylglutamine of 90 - 96%: 2 - 5%: 2 - 5%, it can meet the requirements of quickly dissolving the stock and better stirring evenly after adding vinyl dimethicone / polymethylsiloxane sesquisiloxane cross-linked polymer, and finally pressing it into a powder cake.

[0017] Among them, vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer is used for adsorbing oil. By using vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer instead of silica, the oil absorption rate and long-lasting makeup effect are effectively improved. In addition, the product can achieve "no titanium dioxide" while improving the soft focus effect and increasing the covering power, and can effectively cover fine lines. At the same time, by using hollow spherical vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer, the oil absorption effect of the powder cake can be effectively improved.

[0018] Isononyl isononanoate is used as an emollient. At the same time, its multi-methyl branched chain structure makes the skin feel fresh after use. It is also used as a solvent in the setting powder cake composition to dissolve dibutyl isooctanoyl glutamine and dibutyl lauroyl glutamine.

[0019] Polydimethylsiloxane is used to combine with vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer, so as to realize more efficient combination of components with isononyl isononanoate.

[0020] Dibutyl isooctanoyl glutamine and dibutyl lauroyl glutamine are used as gelling agents to increase the hardness of the product.

[0021] Octyldodecanol, ethyl ethyl glycerin, and phenoxyethanol are used as preservatives.

[0022] The preparation method of the setting powder cake composition includes the following steps: Step S1: Weigh isononyl isononanoate, dibutyl isooctanoyl glutamine, and dibutyl lauroyl glutamine and mix them into a liquid mixture (dibutyl isooctanoyl glutamine and dibutyl lauroyl glutamine are white powdery solids, and isononyl isononanoate is a transparent liquid). The liquid mixture is contained in a first beaker, and the first beaker is heated by a heating plate to heat the liquid mixture. The heating temperature of the heating plate is set to 210°C. While heating, the liquid mixture in the first beaker is stirred until dibutyl isooctanoyl glutamine and dibutyl lauroyl glutamine are completely dissolved and become transparent. The dissolved liquid mixture is kept at a constant temperature and left for later use. Step S2: Weigh polydimethylsiloxane and vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer and mix them into a powder mixture, which is contained in a second beaker. The powder mixture is stirred evenly by a stirrer. The powder mixture is uniform and without caking, which means it is stirred evenly. When starting to stir, the material is a white powder and a transparent liquid. After stirring evenly, a white gel-like powder is obtained. Step S3: Add the powder mixture into the liquid mixture. At this time, the first beaker stores the mixed composition. Then, place the first beaker under the stirrer and slowly stir until the mixed composition becomes semi-transparent. Then, weigh caprylyl glycol, ethylhexylglycerin, and phenoxyethanol and add them into the composition. After stirring evenly again, discharge the mixture for standby; Step S4: Uniformly fill the standby material obtained in Step S3 into an aluminum tray. Place the aluminum tray in a powder pressing mold and use elastic cloth as the powder pressing medium. Use a semi-automatic powder press to press twice with a pressure parameter of 80 ± 20 kg / cm². Keep the pressure for 2 s for the first time and 1 s for the second time, thereby obtaining the Figure 1 semi-transparent setting powder cake composition as shown.

[0023] Example 1: In this example, the composition components of the setting powder cake composition are shown in Table 1 below.

[0024] Table 1 Components and their mass percentages included in Example 1.

[0025] Example 2: The difference from Example 1 is that the composition components of the setting powder cake composition are shown in Table 2 below.

[0026] Table 2 Components and their mass percentages included in Example 2.

[0027] Example 3: The difference from Example 1 is that the composition components of the setting powder cake composition are shown in Table 3 below.

[0028] Table 3 Components and their mass percentages included in Example 3.

[0029] Control Group 1: Table 4 Components and their mass percentages included in the traditional setting powder cake.

[0030] Control Group 2: Table 5 Components and their mass percentages included in the traditional setting powder cake.

[0031] The effect comparisons of Examples 1 to 3 and Control Groups 1 and 2 are shown in Table 6 below.

[0032] Table 6 Effect comparison.

[0033] Among them, the oil absorption rate was measured by the weighing method. A certain amount of grease was applied to the epidermis of a specific material (simulating the skin), and the formulation was covered thereon. A certain pressure was applied and maintained for a fixed time. The weight gain of the sample after absorbing the grease was measured, and then the oil absorption rate was calculated. The long-lasting makeup time was obtained by 10 volunteers trying five groups of samples within 5 days and observing the long-lasting makeup duration and the degree of fit. The smooth feeling and the skin feeling were obtained by 10 volunteers scoring the makeup effect after trying five groups of samples.

[0034] In summary, the oil absorption rate, long-lasting makeup time, smooth feeling and skin feeling of Examples 1 to 3 of the setting powder cake composition are all significantly better than those of Comparative Group 1 and Comparative Group 2. It can achieve the effect of delicate skin feeling without powdery feeling and being smoother, and at the same time, it is fresh without base color.

[0035] By using vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer instead of silica in the setting powder cake composition, the oil absorption rate of the powder composition is greatly improved, achieving long-lasting makeup and high-efficiency setting. The combination of isononyl isononanoate, dibutyl isooctanoyl glutamine and dibutyl lauroyl glutamine is used to increase the hardness of the powder polymer, making the makeup application more convenient, and also making the skin feeling of using the setting powder cake composition more fresh and non-greasy, and having a skin-moisturizing effect. In addition, the use of unnecessary raw materials such as talc, silica, titanium dioxide, etc. is avoided, greatly reducing environmental pollution.

[0036] Although the embodiments of the present invention are described with actual solutions, they do not constitute a limitation to the meaning of the present invention. For those skilled in the art, the modification of its implementation solutions according to this specification and the combination with other solutions are obvious.
