Description

Technology Field

[0001] The present invention relates to a coated powder of pearlescent pigment for cosmetics, a method for manufacturing the same, and cosmetics containing the same. More specifically, the invention relates to a coated powder of pearlescent pigment for cosmetics used as a pigment in color cosmetics, which improves dispersibility, cosmetic longevity, skin adhesion, and usability by coating the powder of pearlescent pigment, a method for manufacturing the same, and cosmetics containing the same. Background Technology

[0003] Cosmetics for the skin are divided into basic cosmetics and color cosmetics. Among these, color cosmetics are applied to a part of the body, mainly the face, to display color, and are used primarily for correction and beautification purposes, such as concealing skin imperfections and changing skin tone to provide a sense of three-dimensionality and color.

[0004] Pearl pigments are widely used in point makeup products such as lipsticks, eyeshadows, and nail polish to create a glossy finish. Additionally, with the recent popularity of base makeup that emphasizes a dewy glow effect, they are now used in makeup bases and foundations, and their use is expanding to include basic skincare products like skin lotions as well as functional cosmetics such as essences.

[0005] Pearlescent pigments exhibit interference colors by coating TiO2 to a specific thickness on a substrate having a plate-like structure with a high aspect ratio. In a similar manner, altering the thickness of Fe2O3 itself or using it in combination with TiO2 produces a non-metallic effect with a pearlescent luster.

[0006] When applying pearlescent pigments to cosmetics, there was a problem in that the makeup's longevity and adhesion were poor, the makeup effect was reduced due to sweat or sebum after application, and the pearlescent pigments were not evenly dispersed within the cosmetic due to poor miscibility with the ingredients in the formulation.

[0007] For this purpose, pearlescent pigments were conventionally used for coating treatment, and the most widely used coating agents are methicone-based and alkylsilane compounds.

[0008] While the pearlescent pigment coated with the aforementioned methicone-based and alkylsilane compounds possesses excellent cosmetic durability, adhesion, and miscibility between raw materials, there was a problem in that it was not evenly dispersed in emulsion formulations even after coating, resulting in the formation of pearl bands; in particular, the pearl band phenomenon was prominent in solid formulations such as lipsticks and semi-solid formulations such as twin cakes. This is because the active movement of pearl particles in high-temperature formulations solidifies as they are when the temperature drops to a low-temperature state, forming a characteristic pearl band. Prior art literature

[0010] (Patent Document 0001) KR 10-1454730 B1 The problem to be solved

[0011] Accordingly, the objective of the present invention is to provide a coating powder of a pearlescent pigment for cosmetics, a method for manufacturing the same, and a cosmetic product containing the same, which improves the cosmetic durability, adhesion, and usability while maintaining the function of the pearlescent pigment, and in particular improves the defect factor of cosmetics that forms pearl bands due to the fluidity of the formulation.

[0012] Another objective of the present invention is to provide a cosmetic product for makeup in which a coating powder is evenly dispersed. means of solving the problem

[0014] The coating powder of the cosmetic pearlescent pigment of the present invention for achieving the above-mentioned purpose is characterized in that 90 to 99 weight percent of the cosmetic pearlescent pigment is coated with 1 to 10 weight percent of silicone oil, and the silicone oil is triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone.

[0015] The above-mentioned coating powder is double- or multiple-coated with triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone and an additional surface modification coating agent, wherein the additional surface modification coating agent is one or more of distearyldimonium chloride, magnesium myristate, aluminum myristate, sodium lauroyl glutamate, triethoxycaprylylsilane, hydrogen dimethicone, dimethicone, and isopropyl titanium triisostearate, and the coating is prepared by diluting triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone with a diluent 50 to 600 times by weight and then coating, The diluent is removed by filtering and drying, and the diluent is characterized as being one or more of lower alcohols having 1 to 6 carbon atoms, dimethicone, and water.

[0016] In addition, the method for manufacturing a coating powder of a pearlescent pigment for cosmetics according to the present invention comprises the steps of: diluting triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone with a diluent of 50 to 600 times by weight; adding a pearlescent pigment for cosmetics to the diluted coating solution and mixing; and filtering and drying the mixed pearlescent pigment mixture, wherein the diluent is one or more of a lower alcohol having 1 to 6 carbon atoms, dimethicone, and water, and the amounts of triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone and pearlescent pigment used are 90 to 99% by weight of the pearlescent pigment for cosmetics and 1 to 10% by weight of triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone.

[0017] A multi-coated powder is manufactured by adding a cosmetic pearlescent pigment to the above-mentioned diluted coating solution and, prior to the mixing step, coating the pearlescent pigment with an additional surface modification coating agent, or by filtering the above-mentioned mixture of pearlescent pigments and then applying an additional surface modification coating agent.

[0019] In addition, the cosmetic product of the present invention is characterized by containing 0.5 to 50 weight percent of the above-described coating powder based on the total amount of the cosmetic composition. Effects of the invention

[0021] According to the present invention, by coating a pearlescent pigment for cosmetics with a specific silicone oil, the dispersibility is improved, thereby improving the defect factor of cosmetics that form pearl bands due to the fluidity of the formulation, as well as improving the durability, adhesion, and usability of the cosmetic. Brief explanation of the drawing

[0023] FIG. 1 is an SEM photograph of Examples 1 and 2 and Comparative Examples 1 and 2 according to Test Example 1 of the present invention. FIG. 2 is a photograph of the manufacturing examples and comparative manufacturing examples according to the present invention. Specific details for implementing the invention

[0024] The present invention will be described in detail below.

[0025] The coating powder of the pearlescent pigment for cosmetics according to the present invention is characterized in that 90 to 99 weight percent of the pearlescent pigment for cosmetics (hereinafter referred to as 'pearl pigment') is coated with 1 to 10 weight percent of silicone oil, and the silicone oil is triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone.

[0027] That is, in the present invention, by selecting a specific silicone oil, specifically Triethoxysilylethyl Polydimethylsiloxyethyl Hexyl Dimethicone, and coating the pearl pigment with it, the problem of forming pearl bands due to the fluidity of the formulation is improved without affecting the function of the pearl pigment, and the cosmetic durability, adhesion, and usability are also improved, and the present invention was completed.

[0029] Here, the pearl pigment exhibits a core-shell structure and may be a natural mica, synthetic mica, glass, alumina, or hollow substrate having a plate-like structure coated with titanium dioxide (TiO2), iron oxide (Fe2O3), or both. Pearl pigments with such a structure are conventionally known and can be commercially purchased and used.

[0031] The above triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone is a silicone oil having the structure of Chemical Formula 1 below.

[0032] [Chemical Formula 1]

[0033]

[0034] The above triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone improves the dispersibility of pearl pigments to resolve the problem of forming pearl bands, and also prevents deformation of the particle shape of the pearl pigments, while also improving water repellency, gloss, adhesion, and durability. This is because if the above triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone is used in an amount of less than 1 weight%, the dispersibility is not sufficiently improved, so the problem of forming pearl bands cannot be resolved, and if it exceeds 10 weight%, clumping may occur due to the excessive amount of triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone, and it may also affect spreadability and flowability.

[0035] At this time, it is preferable to prepare the above triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone by diluting it with a diluent at a ratio of 50 to 600 times by weight, coating it, and then filtering and drying the diluent. This is to prevent the shape of the pearl particles from breaking during coating. The above diluent uses one or more of a lower alcohol having 1 to 6 carbon atoms, dimethicone, and water.

[0036] In addition, the cosmetic coating powder according to the present invention may be double or multiplely coated with triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone as well as additional surface modification coating agents.

[0037] The above-mentioned additional surface modification coating agent provides additional functions and may select and use one or more of Distearyldimonium Chloride, Magnesium Myristate, Aluminum Myristate, Sodium Lauroyl Glutamate, Triethoxycaprylylsilane, Hydrogen Dimethicone, Dimethicone, and Isopropyl Titanium Triisostearate. In this case, the above-mentioned additional function means further improving adhesion, durability, dispersion ability, gloss, etc.

[0038] In addition, the above triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone and the additional surface modification coating agent do not limit the coating order; thus, the triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone may be coated first and the additional surface modification coating agent may be coated second, or conversely, the additional surface modification coating agent may be coated first, or a triple structure may be formed by coating before and after the triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone.

[0039] In the present invention, the additional surface modification coating agent is included in an amount of 0.5 to 10 weight%, specifically 80 to 98.5 weight% of pearl pigment, 1 to 10 weight% of triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone, and 0.5 to 10 weight% of the additional surface modification coating agent.

[0041] The method for manufacturing a coating powder of a pearlescent pigment for cosmetics according to the present invention comprises the steps of: diluting triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone with 50 to 600 times by weight of a diluent; adding a pearlescent pigment for cosmetics to the diluted coating solution and mixing; and filtering and drying the mixed pearlescent pigment mixture, wherein the diluent is one or more of a lower alcohol having 1 to 6 carbon atoms, dimethicone, and water.

[0043] The step of diluting the above triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone is intended to minimize deformation of the pearl particles during coating. Since using too little diluent can cause deformation of the particles and using too much may result in poor coating, it is diluted by 50 to 600 times the weight.

[0044] Then, the pearl pigment is slowly added to the diluted coating solution while stirring at 300 to 900 pm for 2 to 10 hours to coat it.

[0045] Next, the above-mentioned mixture is filtered, dried, and sieved to obtain a cosmetic filler pigment, i.e., a coating powder.

[0046] Here, the above filtration and drying methods are not limited, and any method known in the field to which this technology belongs is sufficient.

[0047] At this time, the amount of the triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone and the pearl pigment used is 90 to 99 weight percent of the pearl pigment and 1 to 10 weight percent of the triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone.

[0049] In addition, if the coating powder of the present invention is to be obtained as a multi-coating powder, the multi-coating powder can be manufactured by adding a cosmetic pearlescent pigment to the diluted coating solution and, prior to the mixing step, coating the pearlescent pigment with an additional surface modification coating agent, or by filtering the mixed pearlescent pigment mixture and then applying an additional surface modification coating agent.

[0050] Here, the additional surface modification coating agent is one or more of Distearyldimonium Chloride, Magnesium Myristate, Aluminum Myristate, Sodium Lauroyl Glutamate, Triethoxycaprylylsilane, Hydrogen Dimethicone, Dimethicone, and Isopropyl Titanium Triisostearate, as previously described.

[0051] The method of coating the above-mentioned additional surface modification coating agent also involves preparing a diluted solution by diluting the additional surface modification coating agent 50 to 600 times by weight with one or more diluents selected from lower alcohols having 1 to 6 carbon atoms, dimethicone, and water, and then adding a pearl pigment to the solution, mixing, filtering, and drying.

[0052] In addition, when multiple coatings are applied, intermediates such as sodium stearate may be added after the first coating solution treatment for reasons such as the role of an intermediate medium due to the wet process and the improvement of usability, and the additional implementation thereof is not restricted.

[0053] At this time, as previously described, the amounts used are preferably 80 to 98.5 weight% of pearl pigment, 1 to 10 weight% of triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone, and 0.5 to 10 weight% of additional surface modification coating agent.

[0055] The coating powder of the present invention manufactured as described above is used as a filler pigment in cosmetics and may be included in an amount of 0.5 to 50 weight percent based on the total amount of the cosmetic composition, and the formulation is not limited. For example, it may be any one of the formulations of lipstick, two-way cake, eyeshadow, blush, makeup base, foundation, skin lotion, essence, and cream.

[0062] Pearl pigment (Sharon ® 98g of Crystal Gold 7001P was added to the coating solution prepared above and mixed at 600 rpm for 4 hours. After mixing was finished, the mixture was filtered using a vacuum filter and dried to produce a coating powder.

[0064] (Example 2)

[0065] 1 g of distearyldimonium chloride at 75°C and 500 g of water were added to a reactor and homogeneously mixed using a magnetic bar to completely dissolve the distearyldimonium chloride, thereby preparing an addition coating solution.

[0066] Then, 98g of pearl pigment (Sharon®Crystal Gold 7001P) was added to the prepared additional coating solution and mixed at 600 rpm for 30 minutes. Next, 0.33g of sodium stearate (96.0%) was dissolved in 100g of water at 75℃ and added, followed by mixing for 1 hour. After mixing, the mixture was filtered using a vacuum filter, dispersed again in hot water, filtered again under vacuum, and washed with hot water.

[0067] Next, 1 g of triethoxysilyl ethyl polydimethylsiloxyethylhexyl dimethicone and 160 g of isopropyl alcohol were added to a reactor equipped with a reflux condenser, and a coating solution was prepared by homogeneously mixing using a magnetic bar.

[0068] In addition, 99g of pearl pigment, which had been previously coated with an additional coating solution and washed, was added to the coating solution and mixed at 600 rpm for 4 hours, then filtered with a vacuum filter and dried to produce a multi-coated powder.

[0070] (Comparative Example 1)

[0071] The pearl pigment (Sharon®Crystal Gold 7001P) was prepared as is.

[0073] (Comparative Example 2)

[0074] A coating solution is prepared by homogeneously mixing 2g of triethoxysilyl ethyl polydimethylsiloxyethylhexyl dimethicone with 4g of dimethicone (KF-96A-1.5CS).

[0075] 98g of pearl pigment (Sharon®Crystal Gold 7001P) was placed into a Henschel mixer, and 6g of the prepared coating solution was sprayed while rotating at 600 rpm. The mixture was stirred for 3 minutes to ensure sufficient mixing. Then, the mixture was dried to produce a coating powder.

[0077] (Comparative Example 3)

[0078] The procedure was carried out in the same manner as in Example 1, but hydrogen diketicone was used instead of triethoxysilylethylpolydimethylsiloxyethylhexyl dimethicone.

[0080] (Comparative Example 4)

[0081] The procedure was carried out in the same manner as Example 1, but triethoxycaprylylsilane was used instead of triethoxysilylethylpolydimethylsiloxyethylhexyldimethicone.

[0087] Examples 1 and 2 and Comparative Examples 1 and 2 were each photographed by SEM, and the results are shown in Figure 1. The presence or absence of deformation of the particle shape after coating is summarized in Table 2 below.

[0088] If the particle shape and particle size of the pearl pigment before coating (Comparative Example 1) and the coated pearl pigment are different, the wavelength range and amount of reflection of the pearl pigment's inherent reflected light change, causing it to appear as a visually different color. As shown in Fig. 1, SEM observation results showed that Comparative Example 1, Example 1, and Example 2 had similar particle shapes and particle sizes, but it was confirmed that pearl breakage was observed in Comparative Example 2 and the particle size had decreased. Therefore, it was confirmed that coating in the same way as Example 1 and Example 2 is suitable for surface treatment of the pearl pigment.

[0108] As can be seen in Table 5 above, in Preparation Example 1, Preparation Example 2 and Comparative Preparation Example 2, in which lipsticks were prepared using a pearl pigment coated with triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone, it was confirmed that the formation of pearl bands was minimal and the dispersibility of the pearl pigment was excellent.

[0110] (Test Example 4)

[0111] In order to compare the actual usage effects of Preparation Example 1, Preparation Example 2 and Comparative Preparation Examples 1 to 4, each preparation example was provided as a stick lipstick to 10 women in their 20s to 40s, and then evaluated on four items including dispersion power of the pearl pigment, color development, adhesion, and durability upon application to the skin, and the results are shown in Table 6 below.

[0116] Dispersion ability: In Preparation Example 1, Preparation Example 2 and Comparative Preparation Example 2, it was confirmed that the dispersion ability of the pearl pigment, which spreads evenly on the lips, was excellent. This means that the pearl pigment treated with triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone has good spreadability when used in actual cosmetics.

[0117] Glossiness: Compared to the pearl pigment without surface coating (Comparative Example 1), the glossiness of Examples 1 and 2 and Comparative Examples 3 and 4, which used a surface-coated pearl pigment, increased. However, the pearl pigment used in Comparative Example 2 (Comparative Example 2) showed reduced glossiness due to the breaking of pearl particles during the coating process, so it was confirmed that the effect of the pearl pigment was reduced even when applied to cosmetics.

[0118] Adhesion: The adhesion of the pearl pigment increased in the lipstick using the coated pearl pigment, and in particular, Preparation Example 2, which used a pearl pigment double-coated with triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone and distearyl dimonium chloride, had the best adhesion.

[0119] Durability: Coating with pearl pigment increases water repellency, which is related to the durability of the makeup. Compared to Comparative Example 1, which used pearl pigment without surface coating, all other examples showed excellent durability.
