Description:
TECHNICAL FIELD 
       [0001]    The present disclosure relates to a cosmetic containing an aluminate composite oxide. 
       BACKGROUND OF THE DISCLOSURE 
       [0002]    It is known that a fluorescent substance is mixed in a cosmetic (for example, patent document 1). Such cosmetic is expected that the color of skin is adjusted by color development derived from the fluorescent substance and an unconventional cosmetic property is shown by specific color derived from the fluorescence. Especially, a compound having a red fluorescence is expected to produce an effect of making the facial color appear bright by providing reddish tint to the skin. 
         [0003]    However, an organic fluorescent substance such as 3-hydroxypyrene-5, 8, 10-trisulfonic acid which has been proposed, and an inorganic fluorescent substance such as NaCl:Mn have not been used substantially because their safety is not confirmed. On the other hand, mineral-based fluorescent substances such as axinite (aluminum calcium borosilicate), calcite (calcium carbonate), and petalite (aluminum lithium silicate) that are considered relatively safe have been proposed (see patent document 2) but they may not be used in a cosmetic because of an insufficient color development. 
         [0004]    A compound represented by a general formula CaAl 12 O 19 :Mn 4+  has been known and disclosed in nonpatent document 1. However, the compound has been investigated as a fluorescent substance for LED and has not been known as a cosmetic component.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0028]    The present disclosure relates to a cosmetic containing inorganic particles consisting of a compound represented by a general formula: Ca x Al y O (2x+3y+4z)/2 :Mn 4+   z  (in the formula, 0.1&lt;x&lt;1.05, 11.9&lt;y≦12, and 0.0005&lt;z&lt;0.1). That is, the cosmetic contains inorganic particles consisting of a compound obtained by doping a compound represented by a general formula Ca x Al y O (2x+3y)/2  with Mn 4+ . CaAl 12 O 19 :Mn 4+  red fluorescent substance had been developed in 1971 (nonpatent document 1). In nonpatent document 1, it is disclosed that Mn 4+  generates red light in the wavelength near 657 nm by removing an octahedron site of CaAl 12 O 19 . 
         [0029]    Recently, research and development of CaAl 12 O 19 : Mn 4+  as red fluorescent substance for white LED have been carried out. However, such red fluorescent compound has not been examined as a material for a cosmetic. 
         [0030]    The inventors found that the inorganic particle of the present disclosure may be used suitably as a material for a cosmetic. That is, the inorganic particle of the present disclosure is safe material which is harmless to human health, and has a high stability and an excellent red color developing property when used. Therefore, a cosmetic showing an unprecedented and good cosmetic appearance can be obtained. 
         [0031]    The inorganic particle of the present disclosure satisfies the requirement that x, y, and z in the formula are within the above-mentioned range. The x, y, and z are preferably set within the following range because a suitable fluorescent properties may be achieved. The x is more preferably more than 0.9 and less than 1.0. The z is more preferably more than 0.001 and less than 0.05. 
         [0032]    The inorganic particles of the present disclosure preferably have a luminance Y in xyz representation system (hereafter described as a luminance Y) of 0.1 or more when a light having an excitation light wavelength of 450 nm is irradiated. When the inorganic particle having a luminance of less than 0.1 are used in a cosmetic, the reddish tint is hardly recognized. The luminance depends on the composition and additives mentioned later, so that the luminance Y may be set at 0.1 or more by adjusting the above-mentioned elements. The luminance Y is preferably 0.1 or more, and more preferably 0.5 or more. In this specification, the luminance Y is measured by the method disclosed in the example. 
         [0033]    The inorganic particle of the present disclosure may contains other metals such as alkaline metals including Li, Na, and K, alkaline earth metals including Be, Mg, Sr, Ba, and Ra, and other metals including Ti, Zr, V, Cr, Mo, W, Fe, Co, Ni, Pd, Pt, Cu, Ag, Zn, Al, Ga, Si, Ge, and Sn within such a range as not to affect safety for a human body and performances. The defined content is not particularly limited but the content of the other metal is preferably 10 wt % or less relative to the inorganic particle of the present disclosure. 
         [0034]    The shape and particle diameter of the inorganic particle of the present disclosure are not particularly limited and an inorganic particle having a hexagonal plate shape may be used. The hexagonal plate-shaped particles have excellent performances in the smoothness, adhesive property and soft focus property so that the particles can be preferably used as a material for a cosmetic. 
         [0035]    It is desirable that the particle diameter of the hexagonal plate-shaped inorganic particles of the present disclosure is 5 to 100 μm. When the particle diameter is less than 5 μm, the emission intensity may be reduced. If the particle diameter is more than 100 μm, the roughness may be generated when the particles are used in a cosmetic. The particle diameter is D50 measured by using a laser diffraction particle size distribution analyzer. 
         [0036]    A ratio between a long diameter and a thickness of the hexagonal-plated inorganic particles of the present disclosure is desirably 0.1 to 1. More desirably, the ratio is 0.1 to 0.5. When the ratio is less than 0.1, the smoothness, the adhesive property and the soft focus property may be deteriorated. When the ratio is more than 1, the emission intensity may be reduced. The long diameter and the thickness are average values of values determined by measuring 250 particles in an image of 1000 magnification taken by using a scanning electron microscope (JSM 840F manufactured by JEOL Ltd.). 
         [0037]    The inorganic particles of the present disclosure preferably have a BET specific surface area (it is also called as specific surface area) of 0.03 to 0.8 m 2 /g. When the BET specific surface area is less than 0.03 m 2 /g, a concealing property is low so that toning may become difficult. When the BET specific surface area is more than 0.8 m 2 /g, coagulated particles may be generated to reduce the dispersibility. The upper limit is more preferably 0.5 m 2 /g. 
         [0038]    A method for producing the inorganic particles of the present disclosure is not particularly limited but the particles may be obtained by a method comprising a step of mixing a Ca source compound, a Mn source compound, and an Al source compound as the raw material in accordance with the mole ratio of the intended compound to prepare a precursor and a step of calcinating. 
         [0039]    The Ca source compound may include calcium carbonate, calcium hydroxide, calcium oxide, calcium chloride, calcium nitrate, calcium sulfate, calcium fluoride, calcium bromide, and calcium iodide. Two or more of these compounds may be used in combination. 
         [0040]    The Al source compound may include aluminum oxide, aluminum chloride, and aluminum sulfate. Two or more of these compounds may be used in combination. 
         [0041]    The Mn source compound may include manganese carbonate, manganese acetate, manganese oxide, manganese sulfate, manganese nitrate, manganese fluoride, and manganese bromide. Two or more of these compounds may be used in combination. 
         [0042]    A flux component may be used according to need at the time of calcinating. The flux component promotes the particle growth or suppress the growth of specified face to make it easy to generate hexagonal plate-shaped particles. Further, it is preferred that the crystallinity becomes high and the emission intensity is improved. 
         [0043]    The flux component is not particularly limited but may include calcium fluoride, magnesium fluoride, aluminum fluoride, ammonium fluoride, magnesium chloride, calcium chloride, ammonium chloride, magnesium bromide, calcium bromide, ammonium bromide, magnesium iodide, calcium iodide, ammonium iodide, boric acid, boron oxide, sodium metaborate, and sodium tetraborate. Two or more of these compounds may be used in combination. 
         [0044]    An amount of the flux component to be used is preferably 0 to 20 mol % relative to the inorganic particles of the present disclosure. When the amount is more than the disclosed value, the emission intensity may be reduced. 
         [0045]    A method for mixing these material compounds may be any known method. For example, a method which comprises preparing a water-based dispersion of the material compound and mixing while stirring or pulverizing by using a wet media mill and then evaporative drying the whole quantity, or a method which comprises dry mixing using a general mixing apparatus such as a henschel mixer, and a tumbler, or a hammer mill, a high pressure air jet mill, or a combination thereof may be used. 
         [0046]    A calcinating method may be any known method. For example, a method of calcinating with a ceramics crucible or a method of calcinating with a rotary kiln while rotating may be used. 
         [0047]    The calcinating is preferably performed under oxidizing calcinating condition such as in the atmosphere. A calcinating temperature is not particularly limited but preferably 1000 to 1800° C., more preferably 1300 to 1600° C. When the temperature is less than 1000° C., the emission intensity may be reduced. When the temperature is more than 1800° C., the particles may be strongly calcinated to deteriorate the dispersibility. 
         [0048]    The particles after calcinating may be subjected to post-treatments such as filtration through a sieve, water washing and other washing, and pulverization as necessary. The particles obtained by repeating once or more times the steps of washing with an acid or alkali after calcinating and calcinating again are especially preferred because they have an improved emission intensity. 
         [0049]    The inorganic particle of the present disclosure may be blended in a cosmetic as it is but may be subjected to a known surface treatment according to need before blending. 
         [0050]    The surface treatment is not particularly limited but any material may be used for the surface treatment if the material can be used for a cosmetic. A coating layer composed of inorganic compounds such as oxides, hydroxides, carbonates, and phosphates of silicone, zinc, titanium, aluminum, zirconium, and tin may be provided. Further, for giving water repellency, dimethylpolysiloxane, methylhydrogenpolysiloxane, methylphenylpolysiloxane, methylmethoxypolysiloxane, dimethylpolysiloxane dihydrogen, and copolymers thereof, stearic acid, lauric acid, oleic acid, and metal salts thereof (aluminum salt, zinc salt, magnesium salt, and calcium salt), polyvinyl alcohol, ethylene glycol, propylene glycol, monoethanolamine, aminomethylpropanol, diethanolamine, triethanolamine, monopropanolamine, dipropanolamine, tripropanolamine, paraffin wax, polyethylene wax, aminosilane, epoxysilane, methacrylsilane, vinylsilane, mercaptosilane, chloroalkylsilane, alkylsilane, fluoroalkylsilane, hexamethylsilazane, hexamethylcyclotrisilazane, trimethylolpropane, trimethylolethane, and pentaerythritol may be included. 
         [0051]    The surface treatment may be performed using a single compound, a lamination process or a mixing process may be performed by using two or more compounds in combination. Further, a coating layer of an organic compound may be provided after the treatment of the inorganic compound, but it is important not to reduce the original lubricating property. 
         [0052]    The coating amount of the inorganic compound and the organic compound is preferably 0.1 to 30 wt % relative to the inorganic particles, more preferably 0.1 to 20 wt %. When the coating amount is 0.1 wt % or more, the function improving effect by the surface treatment can be exerted. When the coating amount is 30 wt % or less, the treatment may be performed without damaging the original lubricating property, and it is advantageous from economic viewpoint. 
         [0053]    A method of the surface treatment is not particularly limited but may be performed by a method comprising adding the inorganic compound or the organic compound to a water-based dispersion of the inorganic particles and then adjusting the pH of the dispersion to coat. Further, water-insoluble organic compounds may be surface-treated by dry mixing an organic compound, and pulverizing or mixing followed by heating according to need for coating the water-insoluble organic compound. 
         [0054]    The cosmetic of the present disclosure preferably contains the inorganic particles of the present disclosure of 0.1 to 100 wt %, more preferably 0.1 to 50 wt %. When the content is less than 0.1 wt %, it is not preferred because the above-mentioned effect cannot be obtained sufficiently. When the content is over 50 wt %, it is not preferred because the content of the powder of the present disclosure is excess so that the degree of freedom for cosmetic composition is reduced to make it difficult to handle. 
         [0055]    Examples of the cosmetic of the present disclosure may include a foundation, a makeup base, an eye shadow, a rouge, a mascara, a lipstick and a sunscreen agent. The cosmetic of the present disclosure can be in any form such as that of an oil-based cosmetic, a water-based cosmetic, an O/W type cosmetic or a W/O type cosmetic. Above all, the cosmetic of the present disclosure can be suitably used in makeup cosmetics including a foundation, a makeup base, and an eye shadow and sunscreen agents.

       Example 4 
       [0086]    Calcium carbonate (manufactured by Sakai Chemical Industry Co., Ltd., CWS-20, 4.74 g), manganese carbonate (manufactured by Chuo Denki Kogyo Co., Ltd., 0.06 g), aluminum oxide (manufactured by Iwatani Chemical Industry Co., Ltd., RG-40, 32.1 g), and calcium fluoride (first class grade chemical manufactured by Wako Pure Chemical Industries, Ltd., 0.37 g) as flux components were weighed and put in water. Then, the mixtures was stirred sufficiently using a planetary ball mill at 250 rpm for 30 minutes. The mixed slurry was dried by evaporation at 130° C. and the obtained solid matter was crushed by using a mortar to obtain calcinating precursor powder. Next, the calcinating precursor 15 g was put in an alumina crucible and heated to 1600° C. at 200° C./hour in the atmosphere. After keeping the temperature for 3 hours, the matter was cooled to room temperature at 200° C./hour. 
         [0087]    The calcinated matter thus obtained was crushed by using a mortar to obtain compound P4. The obtained electron microscope photographs of P4 are shown in  FIGS. 7 and 8 . When P1 is expressed by a general formula, Ca x Al y O (2x+3y+4z)/2 :Mn 4+   z , X=0.99, Y=12.00, and Z=0.01.

         [0097]    These materials were weighed according to the composition and mixed while stirring by a coffee mill for one minute and 30 seconds. The obtained powder mixture 0.8 g was weighed in a metal mold with a diameter of 20 mm 0 and pressed using a press machine under a pressure of 200 kgf/cm 2  for 30 seconds to obtain powder foundation F7. 
       Evaluation Example 1 
     Evaluation as Fluorescent Substance 
       [0098]    The fluorescent substance samples P1 to P6 obtained in examples were evaluated. 
       [Measurement of Luminance Y] 
       [0099]    The emission spectra was measured by using FP-6500 manufactured by JASCO Corporation where the excitation wavelength was set at 450 nm. ISF-513 type was used as a fluorescent integral sphere, and the value of voltage of photomultiplier tube was set at 400. 
         [0100]    Relative Luminance 
         [0101]    The Y value of P1 was set to 100, and the relative luminance of P1 to P6 respectively was calculated. The results are shown in table 7. 
       [Shape of Fluorescent Substance Particle] 
       [0102]    The SEM photographs of P1 to P6 with 1000 and 2000 magnifications were taken by using a SEM (840F manufactured by JEOL Ltd.) for confirming the shape of the fluorescent substance particles. The results are shown in  FIGS. 1 to 10 . From  FIGS. 1 to 10 , it is clear that the inorganic particles obtained in examples are hexagonal-plate shaped. 
       [Identification of Fluorescent Substance] 
       [0103]    The measurement by XRD (RINT-TTRIII manufactured by Rigaku Corporation, x-rays=CuKα, λ1.5406 Å, 50 kV, 300 mA) was performed for identification of the product P1 obtained in example 1. The measurement result matched PDF card #01-084-1613 (RDB), and it was confirmed that the composition of P1 was almost the same as CaAl 12 O 19 :Mn 4+  from the result of  FIG. 11 . The result is shown in  FIG. 11 . 
       Evaluation Example 2 
     Evaluation as Cosmetic 
       [0104]    The foundations of F1 to F7 obtained in examples 1 to 6 and comparative example 1 were applied by ten panelists under the condition that the numbers of foundations were not noticed by the panelists. Then, the color was tested with the irradiation of black light at 365 nm. The results of evaluation into five levels of reddish tint are shown in table 8.

         [0105]    From these results, it is clear that the powder of the present disclosure can improve the optical functions. 
       INDUSTRIAL APPLICABILITY 
       [0106]    The cosmetic of the present disclosure may have excellent effects in covering color of the skin and imparting transparency to the skin so that it can be used suitably as makeup cosmetics including a foundation. 
         [0107]    The cosmetic of the present disclosure can develop the effect especially outside under natural light because the reddish tint becomes strong when an ultraviolet ray at 365 nm in natural light (sunlight) is irradiated. In addition, the cosmetic can develop the effect even indoors because emission is generated in the visible region.
