Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a makeup cosmetic in which a makeup film does not transfer to clothes and has a long lasting makeup. More specifically, by using the cohesive force and adhesion of the fine particle powder and the adhesion of the oily component, a film having a strong bonding force with the skin is formed, and the transfer of the powder to clothes etc. is suppressed. The present invention relates to a makeup cosmetic which has a long-lasting effect. 2. Description of the Related Art
The foundation comprises a coloring agent such as iron oxide, a hiding agent such as titanium oxide, an extender such as talc, a resin powder, a functional powder such as ultrafine titanium oxide, and an oil agent. [0003] These powders are fixed to the skin by the adhesive force of the powders themselves or the binding force of an oil agent. However, these adhesive and bonding forces are generally weak,
It was not possible to prevent the transfer of the decorative coating to clothing or hands. [0004] In particular, when a plate-like powder such as talc is used, there is a problem that the transfer of the decorative coating film to clothes or hands increases. [0005] In addition, even when a fluorine compound such as perfluoropolyether or a fluorinated powder, which is often used in "lasting type" cosmetics in recent years, is used, the bonding force between the powder and the skin is basically increased. Was weak and could not prevent the transfer of the decorative coating to clothing or hands. On the other hand, the present inventors have found that, in a slurry system in which fine particle powders are strongly dispersed in a solvent to form smaller secondary particles, the fine particle powders generated when the solvent evaporates are strongly affected. By using cohesion, a strong bonding force between the skin and the pigment can be obtained instead of the conventional binder.By using this bonding force, the makeup coating film does not transfer to the clothes, and the face wash can be performed with the makeup applied. We have found that a makeup cosmetic that can be used can be obtained. Further, a fluorine-modified silicone resin having a silanol group in a molecule (hereinafter referred to as FQ resin), which is a compound having a strong adhesive force and a property of not dissolving in squalene, is compounded as an oily component. Thus, it was found that a makeup cosmetic having a stronger bonding force to the skin and an improved persistence of sebum on the makeup can be obtained. Accordingly, an object of the present invention is to use an oily component having a strong cohesive force and a strong adhesive force of fine particle powder in combination,
Another object of the present invention is to provide a makeup cosmetic which does not transfer a cosmetic coating film to clothes and which has excellent makeup persistence by not using a powder which is easy to transfer such as a plate-like powder. According to the present invention, it is essential that a fine particle powder having a primary particle size in a range of 1 to 350 nm contains a white powder and a colored powder. and particulate powder one or more of, a fluorine-modified silicone resin having a silanol group in the molecule, less in the following structure
An oil component containing a resin having both Si0 _4/2 units ,
In a solvent containing cyclic silicone and / or light liquid isoparaffin, the secondary aggregate of the fine particle powder is broken.
The present invention relates to a makeup cosmetic containing a dispersed slurry or paste obtained by crushing . Average formula R ¹ _n SiO _{(4-n) / 2} (provided that R ¹ is a hydrocarbon group having 1 to 8 carbon atoms, a phenyl group, a hydroxyl group, or a general formula —R ² —Rf, and a hydroxyl group and a general formula —R ² —Rf is arbitrarily selected from functional groups essential, R ² is a divalent alkylene group having 2 to 6 carbon atoms, Rf is a perfluoroalkyl group having 1 to 8 carbon atoms, and n is an average. The number is 1.0 ≦ n ≦ 1.8.) The structure of the present invention will be described below in detail. The fine particle powder used in the present invention has a primary particle diameter in the range of 1 to 350 nm. As a method for measuring the primary particle diameter, observation with a transmission electron microscope (TEM) or a scanning electron microscope (SE
M) The particle size obtained from observation is used. When the shape of the fine particle powder is spherical, the diameter of the sphere is defined as the particle diameter. When the shape of the fine particle powder is acicular or rod-shaped, the minor diameter is defined as the particle diameter. In the case of an irregular type, the average particle size from the center is used as the particle size. As for the relationship between the particle size distribution and the primary particle size, when the particle size distribution is narrow, the average primary particle size may be used as the particle size. We need to distinguish our bodies. In the fine particle powder used in the present invention, a powder having a primary particle diameter of less than 1 nm is not preferable because it has high activity and is unstable, and may cause problems such as deterioration of cosmetics. Powders having a primary particle diameter of 350 nm or more have insufficient cohesive force as a fine particle powder, so that the blending amount needs to be limited. The fine particle powder used in the present invention is preferably blended in an amount of 3 to 60 parts by weight, more preferably 5 to 40 parts by weight, based on 100 parts by weight of the makeup cosmetic. The fine particle powder used in the present invention is 15 to 10 parts by weight of the total powder mixed in the makeup cosmetic.
It is preferable to add 0%, more preferably 30 to 100%. Furthermore, the primary particle diameter is 10 to 100
When it is specified to the fine particle powder in the range of nm, it is particularly preferable that the fine powder is blended in a range of 25 to 100% of the total powder weight blended in the makeup cosmetic. The fine particle powder used in the present invention comprises a white powder and a colored powder. Examples of the white powder include titanium oxide, zinc oxide, aluminum oxide, silicon oxide (silicic anhydride), zirconium oxide, calcium carbonate, barium carbonate, and barium sulfate. Also, as titanium oxide,
Any of a crystalline type such as rutile, anatase, and amorphous, and an amorphous type may be used. Further, the colored powder may be inorganic powder or organic powder. For example, yellow iron oxide, red iron oxide, black iron oxide, iron-containing titanium oxide, lower titanium oxide, cerium oxide, cobalt oxide, cobalt titanate, lithium cobalt titanate, titanium-titanium oxide sintered body, copper chlorophyll, porphyrin-based Compound,
Examples include gold, silver, platinum, carbon black, silicon carbide, organic dyes, organic dyes, and the like. These materials may be combined with each other, or may be combined with a powder of aluminum oxide, silicon oxide (silicic anhydride), zirconium oxide or the like. Furthermore, surface treatments such as a silicone treatment, a fluorine compound treatment, a silane coupling agent treatment, an acylated lysine treatment, a fatty acid treatment, a metal soap treatment, and an amino acid treatment may be performed. A preferred method of these surface treatments is, for example, an alkylalkoxysilane treatment. As the alkylalkoxysilane, R ¹ _X Si
(OR ² ) _4-X (where R ¹ is an alkyl chain having 4 to 10 carbon atoms, R ² is an alkyl chain having 1 to 3 carbon atoms or a straight chain or a side chain, and X is 1 to 3 The compound represented by the following chemical formula can be used. As a surface treatment method, alkylalkoxysilane is mixed with fine particle powder, sprayed,
A method of performing a heating reaction under an atmosphere selected from one of nitrogen, an inert gas, and dry air, or more. By having an alkyl chain having 4 to 10 carbon atoms on the surface of the fine particles, sedimentation and caking of the fine particle powder in the cosmetic over time can be suppressed, and the redispersibility can be further improved. It is also important that the powder surface-treated by this surface treatment method has good compatibility with trimethylsiloxysilicic acid and acrylic silicone, and that no reaction such as precipitation or aggregation occurs. The fine particle powder used in the present invention may be subjected to a drying and dehydrating treatment before use. Since fine particle powder generally absorbs moisture easily, the transferability and viscosity may change depending on the amount of moisture absorption. Of these fine particle powders, colored powders such as iron oxide / titanium oxide sintered products and dye-dyed powders are preferred because color separation in cosmetics hardly occurs. Further, the shape is preferably spherical, from the viewpoint of obtaining a strong cohesive force, but it may be a needle, rod, irregular shape or the like. As an example of a method for producing fine particle powder,
Various methods such as a gas phase method, a liquid phase method, and a plasma method are exemplified, and any of these methods may be used. Furthermore, as a result of the difference in the cohesive force between the fine particle powders depending on the manufacturing method, the secondary particle diameter is often greatly different, but in the present invention, provided that the transfer rate is within a specified range, only the primary particle diameter is The size of the secondary particle diameter does not matter as long as it is within the specified range. In the makeup cosmetic of the present invention, various powders conventionally used in cosmetics can be used as powders other than the fine particle powder. Is preferred. For example, nylon powder,
Silicone powder, silicone elastomer, urethane powder, polyethylene powder, Teflon powder, styrene powder, acrylic resin, silicone resin powder, cellulose powder, silk powder, etc. are preferred, and silicone elastomer and silicone powder are particularly preferred. Examples of powders other than the resin powder include yellow iron oxide, red iron oxide, black iron oxide, chromium oxide, cobalt oxide, ultramarine, navy blue, zinc oxide, titanium oxide, zirconium oxide, and silicon oxide. , Aluminum oxide, cerium oxide, titanium mica, barium sulfate, calcium carbonate, magnesium carbonate, aluminum silicate, magnesium silicate, pigment,
Surface treatments such as silicone treatment, fluorine compound treatment, silane coupling agent treatment, silane treatment, organic titanate treatment, acylated lysine treatment, fatty acid treatment, metal soap treatment, oil agent treatment, amino acid treatment, etc. You may give it. However, plate-like minerals such as sericite lower the effect of preventing transfer of the makeup cosmetic of the present invention and cause color fading. As the compounding amount of the plate-like mineral,
It is preferable not to use 0 to 3 parts by weight, more preferably 0 part by weight, based on 100 parts by weight of the cosmetic. The FQ resin used in the present invention is a fluorine-modified silicone resin having a silanol group in the molecule,
Refers to a resin having the following structure and having at least Si04 _{/ 2} units . Average formula R ¹ _n SiO _{(4-n) / 2} (provided that R ¹ is a hydrocarbon group having 1 to 8 carbon atoms, a phenyl group, a hydroxyl group, or a general formula —R ² —Rf, and a hydroxyl group and a general formula —R ² —Rf is arbitrarily selected from functional groups essential, R ² is a divalent alkylene group having 2 to 6 carbon atoms, Rf is a perfluoroalkyl group having 1 to 8 carbon atoms, and n is an average. 1.0 ≦ n ≦ 1.8 in number.) The amount of the FQ resin of the present invention is 10
The amount is preferably 0.5 to 30 parts by weight, more preferably 3 to 10 parts by weight, based on 0 parts by weight. The FQ resin of the present invention is preferably used by dissolving it in cyclic silicone or light liquid isoparaffin in advance. As the solvent used in the present invention, cyclic silicones (octamethylcyclotetrasiloxane (hereinafter, referred to as D4) and decamethylcyclopentasiloxane (hereinafter, referred to as D5) are preferable from the relationship between the volatilization rate and the cohesive force. ), A solvent selected from light liquid isoparaffins. However, since octamethylcyclotetrasiloxane may freeze depending on the season, a solvent obtained by mixing octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane is most preferable. Other solvent components include ethanol,
Lower alcohols such as isopropyl alcohol, isoparaffin, hexameric or higher cyclic silicones, tetramethyltetrahydrogencyclotetrasiloxane, ethers, LPG, fluorocarbon, N-methylpyrrolidone, Freon, fluoroalcohol, volatile linear silicone, etc. However, it is not particularly limited as long as it has a function as a solvent and there is no safety problem. The amount of the solvent component is preferably 20 to 95 parts by weight, more preferably 30 to 85 parts by weight, based on 100 parts by weight of the makeup cosmetic. [0028] In the present invention, it crushed fine powder using a strong mechanical grinding force. Fine particle powders are usually stabilized by forming secondary agglomerates, and the cohesive force between the particles is significantly reduced as compared with the primary particles alone. Break down this secondary aggregate to give stronger cohesion when using cosmetics
Need . As a method of mechanical pulverization, generally, a wet type pulverizer having a continuous and strong pulverizing power is preferable, for example, a roller mill, a paint conditioner, a bead mill, a sand mill, a dyno mill, a micros, a diamond fine mill, a homogenizer, and the like. An apparatus having a strong crushing force may be used. As the grinding media of the wet media type grinding machine,
For example, alumina, zirconia, glass beads and the like can be mentioned, but there is no particular limitation. In the present invention, in order to obtain a make-up cosmetic in the form of a solution, the above-mentioned wet pulverizer may be used as it is, but in order to obtain a make-up cosmetic in a semi-solid form, dry pulverization is required. Since there is a problem that it is difficult to obtain a force, it is preferable to use a method such as flushing for replacing the solvent after wet pulverization, or filling the container with a solution bulk and then distilling off or sucking the solvent. Further, it is possible to obtain a solid makeup cosmetic by removing the solvent, but there is a problem because the transfer rate exceeds the transfer rate specified in the present invention. Further, as a method of producing a makeup cosmetic of the present invention, a strongly dispersed slurry or paste of fine particle powder is prepared for each color, and the slurry is mixed by changing the mixing ratio for each color of the product.

The evaluation methods of Examples and Comparative Examples used in the present invention are as follows. [0042] Twenty female panelists aged 20 to 40 years old were asked to use the cosmetics prepared in Examples and Comparative Examples.
Questionnaire responses were obtained regarding the transferability of cosmetics to tissue paper and the persistence of makeup. The transferability to tissue paper (tissue-off property) was defined as the transferability index by the total number of panelists who answered that transfer was difficult and that transfer was difficult. Therefore, it indicates that the larger the number, the more difficult it is to transfer.
The measurement was performed 10 minutes and 2 hours after application. Regarding the makeup persistence, the presence or absence of makeup collapse 4 hours after application was determined by using the total number of panelists who answered that there was no or almost no makeup loss as an index of makeup persistence. Therefore, the larger the number is, the more excellent the makeup persistence is. Production Example 1 147 parts by weight of a 16% by weight aqueous hydrochloric acid solution were placed in a reactor, and a mixture of 154 parts by weight of sodium silicate No. 3 (manufactured by Nippon Chemical Industry), 220 parts by weight of water, and 158 parts by weight of isopropyl alcohol After adding parts by weight with stirring, CF ₃ CH

As a result, the amount of hydroxyl groups was 2.0% by weight. Example 1 A foundation was prepared according to the formulation shown in Table 1. [Table 1] ¹⁾ 2-Ethylhexyl paramethoxycinnamate: manufactured by Givaudan A mixture of each component is strongly dispersed using Micros (manufactured by Nara Machinery Co., Ltd.), and the product is filled in a closed container together with stainless steel balls.

After spraying 10 parts by weight of an alkoxysilane represented by the formula (1), the mixture was heated under a nitrogen atmosphere at 110 ° C. for 8 hours with gentle stirring, and then heated under air circulation at 100 ° C. for 5 hours with gentle stirring. And deodorized. [Table 2] The mixture of component A was strongly dispersed using a paint conditioner, mixed with component B, pulverized with a micros, and filled in a closed container together with stainless balls to obtain a product. Comparative Example 1 A product was obtained in the same manner as in Example 1 except that trimethylsiloxysilicic acid was used instead of the FQ resin of Example 1. Comparative Example 2 A foundation was prepared according to the formulation shown in Table 3. Example in the case of not using fine particle titanium oxide. [Table 3] After the mixture of each component was strongly dispersed using a paint conditioner, the mixture was filled together with a stainless steel ball into a closed container to obtain a product. Table 4 shows the evaluation results of the transferability and the cosmetic durability. [Table 4] From the results shown in Table 4, it can be seen that the examples of the present invention have lower transferability and higher cosmetic persistence than the comparative examples. Compared to Example 1 in which the FQ resin was blended, Comparative Example 1 compared the case where the FQ resin was replaced with trimethylsiloxysilicic acid. In the results of Comparative Example, no difference was observed in the transferability immediately after the application, but it was found that the difference gradually increased after 2 hours and 4 hours. Also, it can be seen that there is a large difference in the evaluation from the beginning when neither the fine particle powder nor the FQ resin is used. From the above, it is apparent that the present invention provides a makeup cosmetic which does not transfer a cosmetic coating film to clothes and has excellent makeup persistence.
