Description

  The present invention relates to a rod-like oily solid cosmetic.

  Conventionally, solid oils such as waxes, liquid oils, semi-solid oils, and powders are blended in stick-like oily solid cosmetics such as lipsticks and stick-like foundations. Among these, solid oil is blended to maintain a rod-like shape, and in addition to other oils, it is favorably blended to improve the feeling of use such as comfort of skin (familiarity with skin). (For example, refer to Patent Documents 1 and 2.)

  However, in order to improve the shape retention stability of the rod-like oily solid cosmetic material having a feeling of use due to the above oil blending, the rod-like oiliness prepared by blending a large amount of oil containing an appropriate solid oil such as 65% by mass or more. Solid cosmetics have good shape retention and good stability over time, but they have deteriorated the feeling of use, and further satisfy the cosmetic finish feeling and the adhesion of the cosmetics at the time of application. It will disappear.

  Even if the blending amount of the solid oil is reduced, not only the feeling of use, the feeling of finishing the cosmetics, and the adhesion of the cosmetics at the time of application are not improved, but also the stability is deteriorated.

  These drawbacks did not give sufficient results even when adjustments were made with components such as oil in the blending.

  In addition, with respect to the hollow polymer powder blended in the present invention, a small tool such as a sponge having the advantages of both a solid powder cosmetic and an oil solid solid with a small amount of oil component of 60% by mass or less. A technique is disclosed in which a composite powder in which the surface of a hollow foamed resin powder is coated with an inorganic powder is blended with an oil-based solid cosmetic used (see Patent Document 3), but 65 according to the present invention. It is different from oily stick-shaped cosmetics containing an oil content of mass% or more. In addition, cosmetics containing composite hollow particles in which inorganic fine powder adheres to the surface of a hollow sphere polymer (see Patent Document 4), cosmetics containing hollow foamed resin powder and organic silicone resin (Patent Document) 5)), and a technique such as mascara (see Patent Document 6) containing a non-aqueous polymer dispersion in which a polymer is dispersed in volatile silicone and a hollow resin powder is disclosed. It is not related to a rod-like oily solid cosmetic prepared by blending a large amount of oil containing oil (65% by mass or more).

JP-A-10-182500 JP 2002-179524 A Japanese Patent No. 3610469 Japanese Patent Laid-Open No. 4-9319 Japanese Patent Laid-Open No. 11-60440 JP 2004-315420 A

  The present invention has been made in view of the above circumstances, and the object thereof is a rod-like oily solid having excellent storage stability such as shape retention over time, good feeling of use, feeling of finished cosmetics, and good adhesion of cosmetics at the time of application. It is to provide cosmetics.

  As a result of diligent research to solve the above problems, the present inventors have found that the above problems can be solved by blending a hollow polymer powder with a specific amount of oil containing a specific amount of solid oil, The present invention has been completed.

  That is, the first invention is a rod-shaped oily solid containing 65.0 to 99.9% by weight of oil containing 8.0 to 20.0% by weight of solid oil in the total amount of the rod-shaped oily solid cosmetic and hollow polymer powder. Cosmetics.

  Moreover, 3rd invention is a rod-shaped oily solid cosmetics as described in said 1st invention whose content of hollow polymer powder is 0.1-4.0 mass% in the rod-shaped oily solid cosmetics whole quantity.

  In the present invention, terms such as liquid, semi-solid, and solid indicate a state at normal temperature. Liquid oils, semi-solid oils, solid oils and the like are all recognized by those skilled in the art. For example, solid oils generally have a melting point of 45 ° C. or higher, preferably 55 ° C. That's all.

  According to the present invention, 8.0 to 20.0% by mass of solid oil in the total amount of the rod-like oily solid cosmetic and 65.0 to 99.9% by mass of the total oil content containing the solid oil With the addition of hollow polymer powder, the rod-like oily solid cosmetic has excellent storage stability, such as shape retention over time, and has a feeling of use, a feeling of finish, and good adhesion of the cosmetic when applied. A solid cosmetic is obtained.

  Hereinafter, the best mode for carrying out the present invention will be described in detail.

  The hollow polymer powder used in the present invention is a powdery sphere made of a polymer, and has a hollow with the polymer as an outer shell. Examples of the polymer that forms the outer shell of the hollow polymer powder include vinyl monomers such as vinyl chloride, vinyl acetate, methyl vinyl ether, styrene, and vinylidene chloride, acrylic acid, acrylic ester, methacrylic acid, and methacrylic ester. , Homopolymers obtained by polymerizing monomers selected from acrylic monomers such as acrylonitrile and methacrylonitrile, and copolymers obtained by polymerizing the two or more monomers. Preferably, it is a copolymer obtained by polymerizing two or more monomers selected from acrylic acid, methacrylic acid or esters thereof, vinylidene chloride, acrylonitrile, and methacrylonitrile. These polymers may be crosslinked with a crosslinking monomer such as divinylbenzene, ethylene glycol dimethacrylate, or triacryl formal.

  The hollow polymer powder is produced, for example, by heating, expanding, or foaming a polymer powder containing a volatile foaming agent that is vaporized by heating, as disclosed in Japanese Patent Publication No. 59-53290. . In the present invention, the hollow foamed polymer powder obtained by the production is preferably used.

  In the production of the hollow foamed polymer powder, the volatile foaming agent is not particularly limited. For example, methane, ethane, propane, butane, isobutane, isobutene, pentane, isopentane, neopentane, hexane, neohexane, heptane, acetylene. And hydrocarbons such as trichlorofluoromethane and dichlorodifluoromethane, and low-boiling compounds such as tetraalkylsilane.

  The hollow polymer powder in the present invention includes a hybrid sphere whose surface is coated with an inorganic powder. In the present invention, all of these are referred to as “hollow polymer powder”.

  The inorganic powder is not particularly limited, and examples thereof include talc, sericite, mica, calcium carbonate, magnesium carbonate, kaolin, boron nitride, titanium oxide, zinc oxide, iron oxide, cerium oxide, zirconium oxide, and silica. Is done. The particle shape of these inorganic powders is not particularly limited, and may be any of granular, spherical, plate-like, needle-like, and the like, and the average particle diameter is not particularly limited, but is preferably 0.001 to 20 μm. The mass ratio of the hollow polymer powder and the inorganic powder is preferably 5:95 to 50:50.

  The method for coating the inorganic powder with the hollow polymer powder is not particularly limited. For example, as disclosed in JP-A-4-9319, the amount of volatile foaming agent contained before foaming or during foaming It is obtained by mixing molecules and inorganic powder and heating. In addition, as other methods, a dispersion of water or organic solvent of inorganic powder and a hollow polymer powder are mixed and dried, or the inorganic powder dispersion is sprayed onto the hollow polymer powder. Examples thereof include a wet treatment method in which coating is performed by a drying method, and a method of compounding by a physical force such as a high impact force.

  The hollow polymer powder according to the present invention preferably has a particle size of 10 to 110 μm, and the true specific gravity is 0.1 to 0.4 when the inorganic powder is coated. In the range of 0.02 to 0.04, it is preferably not covered.

  The hollow polymer powder used in the present invention is generally commercially available, and commercially available products can be used. Examples of commercially available products include Matsumoto Microsphere (registered by Matsumoto Yushi Seiyaku Co., Ltd.). Trademark; not shown below) As F-E series, F-30E (particle size 30-60 μm, solid content 10-15%, true specific gravity 0.020-0.030), F-50E (particle size 40-70 μm, Solid content 10-20%, true specific gravity 0.020-0.040), F-80E (particle size 90-110 μm, solid content 10-20%, true specific gravity 0.020-0.030), F-80ED ( As the Matsumoto Microsphere MFL series coated with inorganic powder, particle size 90-110 μm, solid content 95% or more, true specific gravity 0.020-0.030), MFL-100CA (particle size 90- 10 μm, true specific gravity 0.13 ± 0.03), MFL-80CA (particle size 90-110 μm, true specific gravity 0.13 ± 0.03), MFL-80GCA (particle size 10-30 μm, true specific gravity 0.20 ±) 0.05), MFL-100SCA (particle size 20-40 μm, true specific gravity 0.20 ± 0.05), MFL-30STI (particle size 10-30 μm, true specific gravity 0.20 ± 0.05), MFL-50STI (Particle size 15 to 45 μm, true specific gravity 0.15 to 0.25).

  In the present invention, by blending the hollow polymer powder into the rod-like oily solid cosmetic material having a specific composition, the weight of the applied cosmetic material is particularly improved. Since many materials can be applied, it can be fitted with a light force. Further, there is no roughness due to the powder during application, and the coating becomes smooth. In addition, there is no change in physical properties such as the hardness that is commonly seen when powder is added, or the stick-shaped cosmetics are easily broken (decrease in breakage value), and the shape of the molded cosmetics also changes. I don't get up.

  Although content of hollow polymer powder is not specifically limited, 0.1-20.0 mass% is preferable in rod-shaped oil-based solid cosmetics whole quantity. A more preferable content is 0.1 to 10.0% by mass in the total amount of the rod-like oily solid cosmetic. When the content is less than 0.1% by mass, the effect of blending the hollow polymer powder cannot be sufficiently obtained. Moreover, even if it mixes exceeding 20.0 mass%, the effect of hollow polymer powder blending will not be enhanced, and the function of other powders can be utilized by suppressing to 20.0 mass% or less. This is also preferable. In particular, 0.1 to 4.0 mass% is preferable in the total amount of the rod-like oily solid cosmetic. When the content is 4.0% by mass or less, the effect of blending the hollow polymer powder can be sufficiently obtained, and the functions of other powders to be used later can be remarkably exhibited. It is preferable because it is possible.

  In the present invention, in addition to the hollow polymer powder, other powders such as an inorganic powder, an organic powder, a pigment, and a dye can be blended as the powder (hereinafter, other than the hollow polymer powder). This powder is called “other powders”.)

One or more solid oils are arbitrarily selected and blended.

  Content of solid oil is 8.0-20.0 mass% in the rod-shaped oil-based solid cosmetics whole quantity. Preferably, it is 10.0-16.0 mass%. When the content is less than 8.0% by mass, the storage stability of the rod-like oily solid cosmetic, such as the shape retention, is poor, the skin feeling is not good, and the cosmetic finish is good. Poor nature. These are not improved even if hollow polymer powder is blended. On the other hand, if it exceeds 20.0% by mass, the feeling of use, the feeling of finishing the cosmetics, and the adhesiveness of the cosmetics at the time of application are poor, and there is no improvement even if hollow polymer powder is blended.

  In this invention, other oils, such as liquid oil other than solid oil, semi-solid oil, are mix | blended.

One or two or more other oils are arbitrarily selected and blended.

  In the present invention, the total amount of oil including 8.0 to 20.0% by mass of the solid oily solid cosmetic material is 65.0 to 99.9% by mass of the total amount of the oily solid bar material. Blended. When the total oil content is less than 65.0% by mass, the storage stability of the rod-like oily solid cosmetics such as shape retention is poor, the skin familiarity is also poor, and the finish of the cosmetics, Adhesion is also poor. These cannot be blended with hollow polymer powder. On the other hand, when the total oil content exceeds 99.9% by mass, the blending effect of the hollow polymer powder is not exhibited.
