Description

  The present invention relates to a powder cosmetic containing a specific titanium dioxide and an iron-containing powder having a specific color, and more specifically, there is little color change between the appearance color and the coating color of the cosmetic, The present invention relates to a powder cosmetic that has smoothness per skin, has no whitening, and has an excellent natural skin color finish.

  Conventionally, titanium dioxide has been designed to have concealability, whiteness, and weather resistance suitable for industrial purposes. For this reason, when conventional titanium dioxide is blended in cosmetics, the hiding property is too high, so that there is a problem of lack of familiarity with the skin and easy whitening. In addition, since the average particle diameter of titanium dioxide that has been used in cosmetics is too small, it is difficult to disperse in a multi-component system such as cosmetics, and is easy to aggregate. There is a problem that color change is likely to occur. Furthermore, since conventional titanium dioxide is not designed from the viewpoint of touch, there are many problems that a granular material is present, and a cosmetic compounded therewith lacks smoothness.

  In order to solve these problems, a technique for obtaining flaky titanium dioxide using a potassium compound has been reported (Patent Document 1). However, the cosmetics using the flaky titanium dioxide have not been sufficiently concealed and smooth per skin. Further, a technique using a titanium dioxide pigment having an average particle diameter of 0.28 to 0.95 μm for cosmetics (Patent Document 2), a primary particle diameter of 0.1 to 14 μm, and an integrated value of a constant particle size distribution. The technology (patent document 3) that uses titanium dioxide defined by the numerical values represented in makeup cosmetics has been reported, but each cosmetic has a smooth skin perception and a natural skin finish. I couldn't say I had it.

  On the other hand, since the average particle diameter of conventional color pigments is also too small, it is difficult to disperse in a multi-component system such as cosmetics, and easily aggregates. There was a problem that the color change was likely to occur.

In order to solve these problems, an organic color pigment is coated on an extender powder to obtain a powder having a translucent powder layer (Patent Document 4), iron-doped titanium, zinc carboxylate, A technique for obtaining a powder obtained by coating a flaky mother powder with a flaky mother powder (Patent Document 5) has been reported. However, cosmetics using these colored pigment-coated body powders and conventional titanium dioxide cannot be said to have smoothness per skin, natural finish, and appropriate concealment. Furthermore, the technique (patent document 6) which mix | blends an iron processing body powder and iron-containing titanium dioxide is reported. However, since this iron-containing titanium dioxide is obtained by adding iron to conventional titanium dioxide, cosmetics using those powders have little color change between the appearance color and the coating color of the cosmetic, Although there is no white float and is excellent in the finish of natural skin color, it was not sufficient in terms of physical properties such as smoothness per skin.

  In this way, even if conventional titanium dioxide is blended, there is little color change between the appearance color and the application color of the cosmetic, there is no white floating, and the cosmetic has excellent smoothness per skin and a natural skin color finish. It was the actual situation that could not be obtained.

JP-A-7-155731 JP-A-6-24938 JP-A-8-277208 JP-A-11-217315 Japanese Patent Laid-Open No. 11-43326 JP-A-7-291835

  Therefore, there is a demand for the development of a cosmetic that has little color change between the appearance color and the application color of the cosmetic, has no white floating, and is excellent in smoothness per skin and a natural skin color finish. An object of the present invention is to provide a blending technique of materials that can obtain such cosmetics.

  As a result of earnest research on the physical properties of titanium dioxide and other materials in order to solve the above problems, the present inventor has obtained titanium dioxide satisfying specific properties and powder containing iron and colored in a specific color tone. It discovered that the cosmetics which can solve the said problem were obtained by mix | blending with cosmetics, and came to complete this invention.

  That is, the present invention is a powder having an average particle size of 1.5 to 2.5 μm, a whiteness of 97.0 or more, and a molded product obtained by pressing the powder has a disintegration strength of 140 g or less. Titanium and Munsell color values of hue 0.00R-10.00, 0.00YR-10.00YR, 0.00Y-10.00Y, lightness 3.00-9.00, saturation 1.00-12 The present invention provides a powder cosmetic characterized by blending iron-containing powder having a color tone in the range of 0.00.

  The present invention also provides a powder cosmetic, wherein the iron-containing powder is iron-containing talc, mica, sericite, barium sulfate, titanium dioxide, silica, or a composite powder thereof. Further, the present invention provides a powder cosmetic characterized in that the iron-containing powder has an average particle size of 0.01 to 40 μm.

  The powder cosmetic of the present invention has little color change between the appearance color and the applied color of the cosmetic, has smoothness per skin when used, and has excellent natural skin color finish without whitening.

  The titanium dioxide of component (a) used in the powder cosmetic of the present invention has a small color change between the appearance color and the application color of the cosmetic, and obtains a cosmetic having a smooth use feeling and a natural finish without whitening. It is blended for the purpose. Therefore, it is necessary that the average particle diameter of the component (a) titanium dioxide is in the range of 1.5 to 2.5 μm. In the present invention, the average particle size means an average particle size of the particle size distribution of primary particles and secondary particles, and 0.05% by mass of titanium dioxide in a 0.3% by mass aqueous solution of sodium hexametaphosphate having a pH of 10.5. (Hereinafter, simply expressed as “%”.) Volume average measured by a laser diffraction particle size distribution analyzer (HORIBA LA-910) manufactured by Horiba, Ltd. Use particle size. If this average particle diameter is smaller than 1.5 μm, it is not preferable because the color change between the appearance color and the application color of the cosmetic is inferior, smoothness per skin, lack of whitening or the like. On the other hand, if the average particle diameter is larger than 2.5 μm, it is not preferable because the color change between the appearance color and the coating color of the cosmetic, the hiding power, and the natural finish are inferior. By blending titanium dioxide with an average particle size of 1.5 to 2.5 μm, there is little color change between the appearance color and application color of cosmetics, and it has a smooth finish and a natural finish with no whitening. You can get a fee.

Further, the titanium dioxide as the component (a) used in the powder cosmetic of the present invention needs to have a whiteness of 97.0 or more. In the present invention, the whiteness refers to 10 g of titanium dioxide filled in a circular aluminum metal pan having a diameter of 5.2 cm and a thickness of 2 mm, and 67.5 kg / cm ² using a hydraulic foot press machine manufactured by Riken Seiki Co., Ltd. It means the lightness value (L value) measured by the Nippon Denshoku Industries Co., Ltd. spectroscopic color difference meter SE-2000. When the whiteness is lower than 97.0, a color dullness occurs when mixed with an oil component, and a cosmetic with good brightness and saturation cannot be obtained. When the whiteness is 97.0 or more, since the color development is good and there is no color dullness, it is possible to obtain a cosmetic with little color change between the appearance color of the cosmetic and the applied color.

  Furthermore, the titanium dioxide as the component (a) used in the powder cosmetic of the present invention needs to have a collapse strength of 140 g or less, preferably 60 to 140 g, of a molded product pressed by a specific method. In general, titanium dioxide has the property that it has high surface activity and is easy to aggregate. If the aggregation is high, it is difficult to disperse uniformly when blended into cosmetics, and the color change between the cosmetic appearance color and the coating color is large. And the presence of a shape as an agglomerate causes a problem that it is difficult to obtain a smooth feel at the time of coating. Therefore, the titanium dioxide of component (a) used in the present invention is agglomerated. Need to be low. Aggregation is a phenomenon in which particles are attracted to each other. Therefore, as a parameter that represents the agglomeration force, the binding force between particles is used, and the force required to collapse a molded product obtained by pressing powder particles at a constant pressure. The bond strength is expressed by a certain collapse strength.

Specifically, the disintegration strength in the present invention is obtained by filling 3.5 g of titanium dioxide into a rectangular metal mold having a length of 31.5 mm and a width of 16 mm, and using a hydraulic press machine manufactured by Riken Seiki Co., Ltd., 155 kg / cm. About the molded object pressed by ² , it means the bending load value (g) measured by the Fudo Kogyo Co., Ltd. rheometer (condition; T-shaped plunger, table raising speed 6 cm / min).

  If it is in the range of the above-described disintegration strength, it is possible to obtain a cosmetic with a smooth use feeling and little color change between the appearance color of the cosmetic and the applied color. When the disintegration strength is larger than 140 g, it is difficult to uniformly disperse when blended in cosmetics, resulting in a problem that the appearance and color change during application increase, and it exists in the form of an aggregate. It is difficult to obtain a smooth feel.

  Titanium dioxide that satisfies the above three conditions can be blended in cosmetics to obtain excellent concealability and cosmetic properties, but more preferably satisfies one or more of the following conditions.

  First, the shape of the titanium dioxide powder is preferably flaky or plate-like. When the shape is flaky or plate-like, it is possible to obtain a cosmetic material that has a smoother feeling of use, is excellent in stretch spread, has an appropriate concealing property, and can form a natural cosmetic film. Specifically, the flaky or plate-like titanium dioxide powder preferably has a ratio of the major axis to the thickness (aspect ratio) of 6 or more, more preferably 7.5 or more. This aspect ratio is obtained, for example, by measuring the major axis and thickness from a 20,000-fold electron micrograph of 50 titanium dioxide particles and calculating the average value of the ratios.

  The titanium dioxide powder preferably has a concealment degree of 32 to 38. In the present invention, the degree of concealment (ΔL) means that 10 parts by mass of titanium dioxide and (alkyl acrylate / dimethicone) copolymer volatile silicone solution (KP-545 manufactured by Shin-Etsu Chemical Co., Ltd.) are volatilized to a resin content of 10% by mass. 90 parts by weight of a mixed silicone (solution prepared with decamethylcyclopentasiloxane) was dispersed for 24 hours in a paint shaker and applied to a glass plate with a thickness of 6 μm. (ΔL = L value (white background) −L value (black background))}. The lower the numerical value of the concealment degree, the higher the concealment power, the lower the transparency, and the higher the tendency to white out. If the degree of hiding is in the range of 32 to 38, moderate hiding power as a cosmetic can be exhibited.

  Furthermore, the rutile ratio of the titanium dioxide powder is preferably 70% or less, particularly preferably 30 to 70%. If an attempt is made to increase the rutile ratio of titanium dioxide, it is necessary to bake at a high temperature. If the bake is carried out at a high temperature, a color dullness tends to occur, and a cosmetic with good brightness and saturation cannot be obtained. Therefore, it is preferable to keep the rutile ratio low, and if it is 70% or less, a cosmetic with good color development and no color dullness can be obtained.

In the present invention, the rutile ratio is a value determined by the following method. That is, a diffraction peak attributed to the (110) plane of rutile (R-type) titanium dioxide and a diffraction peak attributed to the (101) plane of anatase (A-type) titanium dioxide measured by an X-ray diffractometer. Each net integral intensity (NET: a value obtained by separately measuring the background in the same measurement range and excluding this influence) is calculated. By using the value X obtained from the following formula using these values and applying a calibration curve prepared in advance from the measurement result of a mixture in which the ratio of rutile titanium dioxide and anatase titanium dioxide is known, the rutile ratio Asked.
X = NET (R type) / {NET (R type) + NET (A type)} × 100

  The X-ray diffraction peak was measured by filling the titanium dioxide with an aluminum cell for X-ray diffraction so that the surface was smooth, and using a RINT-2200 manufactured by Rigaku Corporation under the conditions shown in Table 1 below.

  The component (a) titanium dioxide used in the powder cosmetic of the present invention is synthesized by a conventionally known method, for example, the method described in WO99 / 11574. As an example, titanium dioxide powder can be obtained by putting flaky titania sol in a crucible, drying and heat-treating it at a temperature of 650 ° C. for 1 hour in an electric furnace, and then pulverizing it using a Coroplex mill manufactured by Alpine.

  The component (a) titanium dioxide used in the powder cosmetic of the present invention can be blended in the cosmetic as it is, but may be surface-treated if necessary. This surface treatment is performed, for example, by coating titanium dioxide with a hydrated oxide and / or oxide of at least one element selected from the group of aluminum, silicon, titanium, zirconium, tin, cobalt and manganese. By coating the surface of titanium dioxide with the above hydrous oxides and oxides, the surface activity of titanium dioxide itself can be reduced, and the color change of appearance and coating color can be achieved with a smoother feeling of use with less cohesiveness. Less cosmetics can be obtained. Moreover, you may use what performed the surface treatment by the well-known method using a fluorine compound, a silicone type compound, metal soap, a lecithin, wax, fats and oils, hydrocarbons, etc., and these 1 type or 2 types or more are used. Can be used.

  The blending amount of the component (a) titanium dioxide used in the powder cosmetics of the present invention gives smoothness per skin, does not cause whitening, and has little color change between the appearance color and the coating color of the cosmetics. In order to realize a smooth skin color finish, 2.5 to 30% is preferable, and 5 to 25% is more preferable.

  The iron-containing powder of the component (b) used in the powder cosmetic of the present invention is blended for the purpose of obtaining a cosmetic with a smooth use feeling and little color change between the appearance color and the coating color of the cosmetic. is there. It is effective for obtaining cosmetics with little color change between the appearance color and the application color of cosmetics by containing iron in the constitution powder with a large blending ratio in cosmetics and suppressing the generation of scattered light. .

Therefore, the iron-containing powder of component (b) used in the powder cosmetic of the present invention needs to have a flesh-tone color tone. The skin color in the present invention refers to 10 g of iron-containing powder filled in a circular aluminum metal pan having a diameter of 5.2 cm and a thickness of 2 mm, and 67.5 kg / cm ² using a hydraulic foot press machine manufactured by Riken Seiki Co., Ltd. In the Munsell color values measured with a spectroscopic color difference meter SE-2000 manufactured by Nippon Denshoku Industries Co., Ltd., hue 0.00R to 10.00R, 0.00YR to 10.00YR , 0.00Y to 10.00Y, lightness 3.00 to 9.00, saturation 1.00 to 12.00.
When the Munsell color value is within this range, a cosmetic having a natural skin color finish with little appearance and color change upon application and no color dullness over time can be obtained. On the other hand, if the Munsell color value deviates from this range, the powder becomes wet with oily components such as sebum after coating, resulting in color dullness over time and naturalness with good brightness and saturation. Cosmetics with a skin-colored finish cannot be obtained.

  The iron-containing powder of the component (b) used in the powder cosmetic of the present invention may be any powder containing an iron compound and having the above-described color tone in the crystal lattice of the mother powder. Examples thereof include a powder incorporating an iron component, a mixed sintered product of iron oxide and mother powder, and a powder whose surface is coated with iron oxide or a hydrous oxide.

  The mother powder is not particularly limited as long as it is a powder normally used in cosmetics, and is an inorganic body powder such as talc, kaolin, mica, sericite, barium sulfate, light magnesium carbonate, light calcium carbonate and the like. Body, nylon powder, polymethyl methacrylate, polyethylene powder, amino acid powder, organosiloxane powder and other organic powders, titanium dioxide, zinc oxide, etc. Things can be used. Among these, talc, mica, sericite, barium sulfate, titanium dioxide, silica or a composite powder of these has a moderate hiding property with less appearance and color change and no whitening. It is preferable because it is easy to obtain cosmetics. Moreover, it is preferable also from a viewpoint of ensuring the moldability at the time of mix | blending the quantity which can acquire those characteristics.

  The production method of the iron-containing powder of the component (b) used in the powder cosmetic of the present invention is not particularly limited, and the dope, the mixed sintered product, the surface coating, etc. by a dry method, a wet method, a mechanochemical method, etc. Synthesized as a powder. For example, after ferric chloride is made into an organosol using a solvent such as a lower alcohol, a mother powder is immersed, dried, fired at 300 to 1000 ° C., and then pulverized. Moreover, when hydrolyzing titanium tetrachloride, ferric chloride is added, hydrous iron oxide is precipitated on the titania surface, and then fired and pulverized.

  The iron content of the iron-containing powder of the component (b) used in the powder cosmetic of the present invention is equivalent to iron oxide in order to realize a natural skin color finish with little color change between the appearance color and the coating color of the cosmetic. 0.5 to 10% is preferable. Within this range, a natural skin color finish can be achieved. In the present invention, the iron content refers to a sample obtained by mixing a mother powder in an iron-containing powder and iron oxide having an appropriate concentration, and measuring the iron atom content by fluorescent X-ray analysis. This means a ratio (%) obtained by creating a calibration curve and converting the measured value of the iron-containing powder into the iron oxide content using the calibration curve.

  The iron-containing powder of component (b) used in the powder cosmetic of the present invention preferably has an average particle size of 0.01 to 40 μm. In the present invention, the average particle size means the average particle size of the particle size distribution of primary particles and secondary particles, and was measured with a laser diffraction particle size distribution measuring device (HORIBA LA-910) manufactured by Horiba, Ltd. Use the average particle size. When this average particle diameter is in the range of 0.01 to 40 μm, the appearance and color change during application are small when blended in cosmetics, and a smooth feel during application can be obtained. Furthermore, what has an average particle diameter of 0.01-1 micrometer is more preferable. In general, when the particle diameter of a powder becomes small, the effect of scattering wavelengths in the short wavelength side region (ultraviolet rays and visible light near blue) tends to be high. Therefore, a more preferable effect can be exhibited in the finish and appearance of a natural skin color and the small color change at the time of application.

  The iron-containing powder of the component (b) used in the powder cosmetic of the present invention can be blended in the cosmetic as it is, but if necessary, a fluorine compound, a silicone compound, a metal soap, lecithin, wax, fats and oils, What carried out surface treatment using hydrocarbon etc. may be used, and these can be used 1 type, or 2 or more types.

  The blending amount of the iron-containing powder of the component (b) used in the powder cosmetic of the present invention has a natural skin color with little color change between the appearance color and the coating color of the cosmetic and no color dullness over time. In order to realize the finish, 2.5 to 60% is preferable, and 5 to 45% is more preferable.

  The powder cosmetics of the present invention can be mixed with powder components other than the above essential components, and can be spherical, needle-like, plate-like, spindle-like, etc. Quality, non-porous particle structure, fumes, fine particles, pigment class and other particle sizes, etc., and any of inorganic powders, organic powders, pigment powders, composite powders, etc. Even a thing can be used and it mix | blends as a base component, a touch adjustment, a coloring component, etc. In addition, these powders may be used as surface-treated powders by surface treatment using a fluorine compound, silicone compound, metal soap, wax, fats and oils, hydrocarbons or the like.

  In the powder cosmetic of the present invention, components that are usually used in cosmetics, that is, an oily component, a surfactant, an oil gelling agent, alcohols, water-soluble, are used as necessary as long as the effects of the present invention are not impaired. In order to impart various effects, a functional polymer, a film-forming agent, an ultraviolet absorber, salts, a pH adjuster, an antioxidant, a moisturizer, a cosmetic ingredient, an antiseptic, a fragrance and the like can be appropriately blended.

  The form of the powder cosmetic of the present invention includes powder, solid, etc., makeup cosmetics such as foundation, white powder, blusher or eye color, skin care cosmetics such as whitening powder, body powder, antiperspirant powder, etc. Can be applied to.

  The present invention will be described in more detail with reference to the following examples, but the present invention is not limited to these examples.
