Description

  The present invention relates to a cosmetic obtained by mixing a cosmetic base material containing powder as a main component with a volatile aqueous solvent to form a slurry, filling the container, removing the solvent, and molding. The present invention relates to a solid powder cosmetic that is excellent in makeup sustainability and excellent in impact resistance and feeling of use by containing a specific binding molding agent, composite powder, and oil agent.

In slurry molding in which a cosmetic base material is mixed with a solvent to form a slurry, and this is filled in a container, and then the solvent is removed and molded, conventionally, volatile oils such as volatile silicone oils and low-boiling hydrocarbons are used. Has been used as a solvent, but in recent years, from the viewpoint of environmental protection, it has become necessary to use a volatile aqueous solvent.
Generally, in slurry molding, the powder is agglomerated using the cohesive strength of the powder when the solvent is removed, resulting in variations in quality due to shrinkage of the molded product, reduced impact resistance, and press Compared to the type of solid powder cosmetics, there are problems such as lowering of makeup sustainability due to poor powder adhesion to the skin. A technique for blending gypsum (for example, Patent Document 1) and a technique for blending powder by hydrophobizing with an oil agent or metal soap (for example, Patent Document 2) are known.

Japanese Patent Laid-Open No. 7-196433 JP-A-10-95711

However, in the above-mentioned solid powder cosmetics, when gypsum is blended as a binding molding agent, gypsum hardens rapidly, so it is difficult to adjust filling conditions, the quality of molded products varies greatly, and the feeling of use is also rough. However, the makeup persistence was not satisfactory. In addition, when all the powders are hydrophobized to improve makeup sustainability, the molding process such as dehydration by centrifugation is complicated, and normal dry molding has a problem in impact resistance.
On the other hand, in general makeup cosmetics, a technique for improving makeup sustainability by blending sebum-adsorptive hydroxyapatite, zinc oxide, etc. is known. When apatite or zinc oxide was blended alone, it was strongly agglomerated due to its strong hydrophilicity, and the molded product was poorly removed from the applicator, resulting in inconvenience in its usability.
For this reason, it has been an object to provide a solid powder cosmetic by aqueous slurry molding excellent in makeup sustainability without impairing impact resistance and feeling of use.

In view of such circumstances, the present inventors have conducted extensive studies to solve the above problems, and as a result, in slurry molding using an aqueous solvent, a specific binder molding agent and hydroxyapatite and / or zinc oxide on the surface of the plate-like powder It is possible to obtain a solid powder cosmetic that is excellent in makeup sustainability and excellent in impact resistance and feeling of use by blending a composite powder that has been coated and further hydrophobized with a specific oil component. The headline and the present invention were completed.
That is, the present invention provides a cosmetic base material obtained by mixing a cosmetic base material containing powder as a main component with a volatile aqueous solvent to form a slurry, filling the container, removing the solvent, and molding. In the composition, the cosmetic base material comprises components (A) to (C);
(A) 5-50% by mass of powder having hydrophilic surface and bond molding
(B) 1-30% by mass of composite powder obtained by coating the surface of plate powder with hydroxyapatite and / or zinc oxide and further hydrophobizing
(C) Oil containing hydrocarbon oil 0.5 to 20% by mass
It is intended to provide a solid powder cosmetic characterized by containing.
The present invention further provides a solid powder cosmetic containing a hydrophobic powder and / or hydrophobically treated spherical powder and / or a polyhydric alcohol and / or a hydrophilic surfactant in the cosmetic base material. is there.

  The solid powder cosmetic of the present invention is prepared by mixing a cosmetic base material containing powder as a main component with a volatile aqueous solvent to form a slurry, filling the container, removing the solvent, and molding. The cosmetics obtained in this way are excellent in makeup sustainability and have excellent quality in impact resistance and feeling of use.

  The powder of component (A) used in the present invention is a powder having a relatively strong cohesiveness by hydration bonding with water and having a hydrophilic surface, and is bonded and molded in the solid powder cosmetic of the present invention. It is a component that acts as an agent and imparts moldability and impact resistance to the molded product. That is, any powder selected by the method described in detail below may be used. For example, talc, mica, synthetic mica, sericite, synthetic phlogopite, titanium mica, barium sulfate, anhydrous silicic acid, calcium carbonate And crystalline cellulose. These may be used alone or in combination of two or more. Similarly, a powder whose surface is hydrophilized by surface treatment or compounding can be used as a bonding molding agent in the present invention as long as it is selected by the method described in detail below.

Here, the selection method of the powder of the component (A) used for this invention is explained in full detail below.
To 100 parts by mass of the powder having a hydrophilic surface, 200 parts by mass of water is added and mixed so that water existing in the outer phase is continuous, that is, in a slurry state. Next, the slurry is poured into a metal pan (a circle having a diameter of 50 mm, a depth of 4.0 mm), and complete drying is performed in a thermostatic bath at 30 ° C. without compression molding. About the solid matter in the dried metal pan, using a rheometer (manufactured by RHEOTHCH FUDOH RHEO METER ROTEX), the needle diameter is 2.0 mmΦ, the penetration speed is 2 cm / min, and the penetration is 0.5 mm. The penetration load value was measured. As a result, a powder having a maximum penetration load value of 30 to 300 g indicated by the rheometer under the above conditions was selected as a powder having a hydrophilic surface and a bond moldability.

The powder selected by the above-described method is a component exhibiting bond moldability that gives impact resistance without causing any problem in the usability of the solid powder cosmetic of the present invention. When the penetration load value indicated by the above-described method is less than 30 g, the effect as a bonding molding agent cannot be remarkably obtained, and sufficient impact resistance cannot be ensured. In addition, for powders exceeding 300 g, the hydration bond between the powder and water is too strong, the molded product becomes difficult to take, and the surface of the molded product causes caking.
Furthermore, from the viewpoint of makeup sustainability, it is more preferable to use a powder other than the component (A) in the cosmetic base material of the present invention after subjecting it to a hydrophobic treatment.

  The content of the component (A) in the present invention is 5 to 50% by mass (hereinafter, simply referred to as “%”) in the cosmetic base material from the viewpoints of moldability, impact resistance, and feeling of use, and particularly preferably. 10 to 40%. When the content of the component (A) is less than 5%, the effect as a binding molding agent cannot be obtained remarkably, so that sufficient impact resistance cannot be secured, and the content exceeds 50%. In addition, the molded product is too hard, and good spread and smoothness cannot be obtained. Therefore, when the content of the component (A) is in the range of 5 to 50%, a solid powder cosmetic excellent in moldability, impact resistance and usability can be obtained.

Component (B) used in the present invention is a composite powder obtained by coating the surface of a plate-like powder with hydroxyapatite and / or zinc oxide and further hydrophobizing it, and adsorbs sebum to impart makeup persistence. It is.
Hydroxyapatite and zinc oxide are highly hydrophilic, and in the slurry molding using the aqueous solvent in the present invention, the agglomeration is strongly agglomerated due to hydration bond with water, which may cause cracks in the molded product, and also feel. The feeling of roughness is large. Therefore, in order to improve the smooth feeling of use and the makeup sustainability while suppressing strong cohesiveness, the surface of the plate-like powder is coated with the powder and further subjected to a hydrophobic treatment and blended.

The composite powder before the hydrophobization treatment has hydroxyapatite and / or zinc oxide on the surface of a plate-like powder usually used in cosmetics having an average particle size of 0.1 to 600 μm and an aspect ratio of 10 to 100 Covered with 0.5 to 50% of the total mass of the composite powder, specifically, those described in JP-A-2002-20218, etc. POWDER La Vie (manufactured by Miyoshi Kasei Co., Ltd.) and the like can be mentioned.
Examples of the hydrophobizing agent used in the composite powder include silicone compounds, fluorine compounds, metal soap, lecithin, hydrogenated lecithin, hydrocarbons, higher fatty acids, higher alcohols, esters, waxes, waxes, surfactants, and the like. The solid powder cosmetics according to the present invention are subjected to a surface treatment of about 0.1 to 10% with respect to the total mass of the composite powder by a commonly known method using one or more of these. Use.

  Content of the component (B) in this invention is 1 to 30% in a cosmetics base material, Most preferably, it is 3 to 20%. If the content of the component (B) is less than 1%, the effect of makeup persistence cannot be obtained remarkably. On the other hand, if it exceeds 30%, the spread and smoothness cannot be obtained due to the rough feeling of hydroxyapatite and / or zinc oxide contained in the composite powder, and the usability is not good. Therefore, when the content of the component (B) is in the range of 1 to 30%, a solid powder cosmetic having excellent makeup sustainability and excellent usability can be obtained.

The oil agent of component (C) used in the present invention may be any as long as it contains hydrocarbon oil and is usually used in cosmetics.
The hydrocarbon oil may be liquid, pasty, solid, liquid paraffin, squalane, petrolatum, polyisobutylene, polybutene, paraffin wax, ceresin wax, microcrystalline wax, ethylene propylene copolymer, montan wax, Fischer-Tropsch wax, etc. These can be used, and these can be used alone or in combination.
Moreover, it is preferable that the ratio of hydrocarbon oil is 40% or more about the oil agent of a component (C). An oil agent having a large interaction with water (for example, an oil agent having a water retention property such as an amino acid cholesterol derivative or a fatty acid ester containing a sugar chain) interacts with water when removing the aqueous solvent in the slurry molding of the present invention. By doing so, drying unevenness may occur on the surface of the molded product, which may cause a problem in appearance quality, or may deteriorate moldability. Therefore, if an oil agent having a ratio of hydrocarbon oil having no interaction with water of 40% or more is used, a solid powder cosmetic having no problem in appearance quality and excellent moldability can be obtained.

  Content of the component (C) in this invention is 0.5 to 20% in a cosmetics base material, Most preferably, it is 2 to 18%. If content of a component (C) is less than 0.5%, the adhesiveness to skin will fall and makeup sustainability will fall. On the other hand, when it exceeds 20%, repeated use of the molded product causes caking (solidification) on the surface, resulting in inconvenience in usability such as poor take-off to the applicator. Therefore, when the content of the component (C) is in the range of 0.5 to 20%, a solid powder cosmetic having excellent makeup sustainability and excellent usability can be obtained.

  Furthermore, in the present invention, the component (D) hydrophobic and / or hydrophobized spherical powder may be blended as a component for further improving the removal of the molded product and imparting further expansion and smoothness. I can do it. The blending amount is preferably about 0.1 to 10% in the cosmetic base material from the viewpoint of usability, and particularly within this range, the makeup persistence is excellent, and the impact resistance and the feeling of use are also excellent. A solid powder cosmetic can be obtained. In the slurry molding method using the aqueous solvent of the present invention, if a hydrophilic spherical powder having a large interaction with water is used, the powder is agglomerated, and the effect is sufficiently exerted in the feeling of use such as elongation and smoothness. Since it may not be able to be exhibited, it is preferable to blend a spherical powder that is hydrophobic and / or hydrophobized.

Examples of hydrophobic spherical powders include organopolysiloxane elastomer, nylon, styrene, etc., and commercially available products include KSP series (manufactured by Shin-Etsu Chemical Co., Ltd.), Toray nylon powder series (Toray Dow Corning Silicone Co., Ltd.) And Gantz Pearl Series (manufactured by Gantz Kasei).
Examples of the spherical powder to be hydrophobized include polyalkyl acrylate, silicic anhydride, polyurethane, etc., and commercially available products include Matsumoto Microsphere Series (manufactured by Matsumoto Yushi Seiyaku Co., Ltd.), God Ball Series (Suzuki Yushi Kogyo Co., Ltd.). Etc.). Examples of the hydrophobizing agent used in the spherical powder include silicone compounds, fluorine compounds, metal soap, lecithin, hydrogenated lecithin, hydrocarbons, higher fatty acids, higher alcohols, esters, waxes, waxes, surfactants, and the like. These can be used, and one or two or more of these can be used for surface treatment by a generally known method and used for the solid powder cosmetic in the present invention.

  In the present invention, it is necessary to form a uniform slurry state in order for the molded product to obtain an appearance quality free from drying unevenness. Therefore, for the purpose of reducing the surface tension of the powder, it is more preferable that the polyhydric alcohol and / or the hydrophilic surfactant as the component (E) are previously blended in the cosmetic base material. The blending amount is preferably approximately 0.5 to 5% in the cosmetic base material, and in particular within this range, a solid powder cosmetic that is more excellent in the appearance quality and feel of use of the molded product can be obtained.

  Examples of the polyhydric alcohol include ethylene glycol, propylene glycol, 1,3-butylene glycol, dipropylene glycol, glycerin, diglycerin and the like, and one or more of these can be used.

As the surfactant, any nonionic surfactant, anionic surfactant and cationic surfactant may be used as long as they are hydrophilic. Specifically, as the nonionic surfactant, polyglycerin fatty acid ester, polyoxyethylene glycerin fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbit fatty acid ester, polyoxyethylene lanolin alcohol, polyoxyethylene cured Castor oil, polyoxyethylene hydrogenated sterol, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, polyethylene glycol fatty acid ester and the like.
Examples of the anionic surfactant include polyoxyethylene alkyl ether phosphoric acid / phosphate, and examples of the cationic surfactant include polyoxyethylene alkylamine and polyoxyethylene fatty acid amide. One or a combination of two or more selected from these surfactants can be used.

  Furthermore, in the present invention, it is more preferable that 40% or more of the powder in the cosmetic base material is composed of a plate-like powder in order to improve the feeling of use such as expansion and smoothness. The plate-like powder is usually used for cosmetics and is not particularly limited as long as it has a particle diameter of 1 to 100 μm and an aspect ratio of 10 to 100, including the components (A) and (B) of the present invention, Examples include talc, mica, synthetic mica, sericite, synthetic phlogopite, titanium mica, barium sulfate, silicic anhydride, bismuth oxychloride, or composite powders based on these, which should be used alone or in combination. Can do.

  The aqueous solvent used in the present invention is used as a solvent for making a cosmetic base material into a slurry, and is one or two kinds selected from water or low-boiling alcohols such as ethyl alcohol, isopropyl alcohol, and normal butanol. It is the above aqueous solution. Further, the proportion of water in the aqueous solvent is preferably 80% or more, particularly preferably water alone, from the viewpoint of impact resistance and feeling of use of the molded product obtained after removing the aqueous solvent. It is possible to improve the solvent removal efficiency by using a low boiling alcohol aqueous solution as an aqueous solvent. However, when the proportion of the low boiling alcohol is 20% or more in the aqueous solvent, it is a molded product due to the interaction with the blended oil agent. May cause unevenness in drying, or a concentration gradient of the blended oil in the molded product, resulting in a difference in feeling of use between the surface layer and the lower layer of the molded product, and a reduction in impact resistance.

  Furthermore, in this invention, in order to make a cosmetic base material into a uniform slurry form using an aqueous solvent, it is preferable to use 50-100 mass parts of aqueous solvents with respect to 100 mass parts of cosmetic base materials. If it is a slurry formed at this quantitative ratio, it is easy to fill the container, the effect of the bonding molding agent is sufficiently exerted, and it becomes difficult to form a crack on the surface of the molded product and a gap with the periphery of the container, A solid powder cosmetic having excellent impact resistance can be obtained.

  The cosmetic of the present invention includes various components other than the components (A) to (C), such as powders, oils, ultraviolet absorbers, humectants, film forming agents, antioxidants, water-soluble polymers, and beauty products. In order to impart various effects, components, preservatives, fragrances, and the like can be appropriately blended within a range that does not impair the effects of the present invention.

The shape is not particularly limited by the shape of the particles, the shape of the fumes, fine particles, pigment grades, etc., the particle structure such as porous, nonporous, etc., inorganic powders, organic powders, dye powders, composites Examples thereof include powders. In addition, these powders have a silicone compound, a fluorine compound, a metal soap, lecithin, hydrogenated lecithin, collagen, in order to impart the characteristics of excellent spreadability, smoothness, and makeup durability in the usability of molded products. It is preferable to use those which have been surface-treated by a generally known method using one or more of hydrocarbon, higher fatty acid, higher alcohol, ester, wax, wax, surfactant and the like.
