TECHNOLOGICAL FIELD OF THE INVENTION The present invention relates to a petal-like cerium oxide powder of a plate-like cerium oxide and an aggregate thereof, a method for producing the same, a coated platy cerium oxide and a collection thereof Petal-like cerium oxide powder of the body, petal-like cerium oxide powder mixed with platy cerium oxide and its aggregate, or petal-like cerium oxide powder coated with platy cerium oxide and its aggregate Cosmetics. [Prior Art] Conventionally, an ultraviolet shielding agent for use in a sunscreen cosmetic or the like can be oxidized by using a metal such as a salicylic acid-based compound or an organic ultraviolet shielding agent of a benzophenone compound or titanium oxide or zinc oxide. An inorganic ultraviolet shielding agent such as fine particles. Among them, when an organic ultraviolet shielding agent is blended with a cosmetic, it exhibits colorlessness and transparency, and is widely used. However, it is low in molecular weight and is likely to be absorbed by the skin. Further, the titanium oxide which is often used as an inorganic ultraviolet shielding agent is chemically stable, but the shielding power is large (the refractive index is high), and there is still a problem that the use of a product having transparency is limited. Further, the zinc oxide has a characteristic that the ultraviolet shielding energy in the UVA region or the visible light region is high, but the zinc ions which are dissolved by sweat or the like are soaked in the skin, and the zinc ions are soaked in the skin. In the future, when looking for the stability of skin tissue, it should be a concern. For this reason, an inorganic ultraviolet shielding agent -5 - 201210947 which has a relatively high transparency of an antimony compound is used among the inorganic ultraviolet shielding agents. For example, in JP-A-2001-139926, it has been proposed to make the surface of the cerium oxide particles having an average primary particle diameter of from 1 nm to 500 nm, or the composite oxide particles containing cerium or the composites thereof, in an amorphous or crystalline form. The inorganic compound coated ultraviolet shielding agent. However, the composite cerium oxide particles described in JP-A-2001-139926 have ultraviolet shielding energy, but they cause aggregation due to fine particles, which may cause problems in use. In addition, in the case of the inorganic ultraviolet shielding agent having a good feeling of use, the composite of the plate-like particles and the cerium oxide powder is examined. For example, in the Japanese Patent Publication No. Hei 10-8 08 8 An ultraviolet absorbing composition composed of a plate-like barium sulfate coated with a metal oxide. However, in the cerium oxide-coated platy barium sulfate particles described in JP-A-10-8028, the ultraviolet shielding energy of the plate-shaped barium sulfate particles is insufficient, and the ultraviolet shielding energy of the composite plate-like particles cannot be obtained. The problem still exists. The present invention has been made in view of the above problems, and an object thereof is to provide a petal-like cerium oxide powder having a plate-like cerium oxide having an average particle diameter of less than 20 μm and an aggregate thereof, and a method for producing the same . Further, it is an object of the invention to provide a cosmetic material which has a high ultraviolet shielding effect and an excellent use feeling by blending the petal-like cerium oxide powder of the plate-like cerium oxide and the aggregate thereof with a cosmetic material.

A cerium oxide powder having a petal-like form having a plate-like cerium oxide having an average primary particle diameter of less than 20 μm or an aggregate thereof can be obtained. Further, it has been found that the surface of the petal-like cerium oxide powder of the obtained plate-like cerium oxide or an aggregate thereof is coated with a compound such as a polyoxyalkylene oxide, an alkyl decane compound, an alkyl titanate compound or a fluorine compound. By the treatment, a powder having hydrophobicity can be obtained, and by blending the same with a cosmetic, it is possible to provide a cosmetic having a high ultraviolet shielding effect and excellent use feeling, and the present invention has been completed.

以及、化妝料之具體實施形態。 本發明之板狀氧化鈽及其集合體之花瓣狀氧化鈽粉體 係平均一次粒徑爲未達20μηι之氧化鈽粉體。在本發明中 ，前述氧化铈粉體的平均厚度宜爲0.2〜4μηι。平均厚度 未達0.2μπι時，係所得到之氧化鈽粉體的厚度不充分，故 易崩壞。另外，若超過4μηι，可見光透明性降低》 又，本發明之板狀氧化鈽及其集合體之花瓣狀氧化鈽 ⑧ -10- 201210947 粉體之平均一次粒徑係以掃描型電子顯微鏡（SEM )，觀 察板狀及其集合體之花瓣狀粒子，計測任意之20個板狀 粒子、或構成其集合體之花瓣狀粒子之板狀粒子的直徑（ 長徑及短徑），算出其平均値來測定》 本發明之板狀氧化姉及其集合體之花瓣狀氧化姉粉體 之平均厚度係以掃描型電子顯微鏡（SEM)，觀察板狀及 其集合體之花瓣狀粒子，計測任意之20個板狀粒子、或 構成其集合體之花瓣狀粒子之板狀粒子的厚度，算出其平 均値來測定。 又，在本發明中，前述板狀氧化鈽及其集合體之花瓣 狀氧化鈽粉體之長寬比（平均一次粒徑/平均厚度）爲2〜 80。此長寬比未達下限値之2時，所得到之氧化鈽粉體不 成爲板狀。另外，若超過上限値之80，所得到之氧化鈽粉 體的厚度不成爲僅保持粒子形狀之厚度。 本發明之板狀氧化鈽及其集合體之花瓣狀氧化鈽粉體 之製造方法係混合成碳酸氫鈉或碳酸鈉之碳酸離子對硝酸 铈或氯化鈽溶液中之鈽離子的莫耳比爲1: 1.5〜1: 5的 範圍內，使混合液之溫度在〇〜40之範圍內靜置或攪拌30 分鐘以上，俾使碳酸鈽粒子析出及成長而得到碳酸鈽八水 合物，再進行燒成，製造板狀、及、其集合體之花瓣狀氧 化铈粉體。（〇〜l〇°C時係板狀氧化铈之集合體的花瓣狀 氧化鈽，爲1 〇〜40°C時係可得到板狀氧化铈）。 前述碳酸離子對铈離子之莫耳比係從板狀及花瓣狀之 形態的維持及生產效率之觀點，宜大於1 .5且小於5。碳 -11 - 201210947 酸離子對姉離子之莫耳比小於1 . 5時係收率變少而生產性 降低，同時板狀粒子之形狀成爲不規則。又，若碳酸離子 對铈離子之莫耳比超過5，離子強度太高而粒子凝集。 使前述硝酸铈或氯化鈽、碳酸氫鈉或碳酸鈉溶解之溶 劑係使用水，但亦可爲含有水之混合溶劑。與水混合之溶 劑係只要爲水溶性之化合物即可，可爲任一者，但宜爲醇 系化合物。醇系化合物可舉例如甲醇、乙醇、丙醇、丁醇

充分的收率得到板狀及其集合體之花瓣狀氧化鈽粉體。另 外，若前述混合液之溫度超過40°C，前述碳酸铈八水合物 粒子的成長反應之進行變快，粒子變細長，具有針狀之形 狀，故，無法得到板狀及其集合體之花瓣狀氧化鈽粉體。 又，使碳酸铈粒子成長之時間未達30分鐘時，係因粒子 之成長途中，在所得到之碳酸铈八水合物粒子中結晶性變 差，形成不定形的粒子，故無法得到板狀及其集合體之花 瓣狀氧化鈽粉體。 ⑧ -12-

DETAILED DESCRIPTION OF THE INVENTION Next, the platy cerium oxide and the collection thereof according to the present invention will be described with reference to the drawings. A petal-shaped cerium oxide powder having a body, a method for producing the same, a petal-like cerium oxide powder having a plate-like cerium oxide coated thereon, and a petal-like cerium oxide powder thereof, and a specific embodiment of the cosmetic material. The petal-like cerium oxide powder system of the aggregate thereof has an average primary particle diameter of cerium oxide powder of less than 20 μm. In the present invention, the average thickness of the cerium oxide powder is preferably 0.2 to 4 μm. When the thickness is less than 0.2 μm, the thickness of the cerium oxide powder obtained is insufficient, so that it is easily collapsed. When the thickness exceeds 4 μm, the transparency of visible light is lowered. Further, the platy cerium oxide of the present invention and the aggregate thereof Petal-like cerium oxide 8 -10- 201210947 The average primary particle size of the powder is observed by scanning electron microscopy (SEM), and the petals of the plate and its aggregate are observed, and any 20 plate-like particles are measured or formed. The average thickness of the plate-like particles of the petaloid particles of the aggregate is calculated by calculating the average enthalpy of the present invention. The average thickness of the petaloid cerium oxide powder of the platy cerium oxide of the present invention and the aggregate thereof is A scanning electron microscope (SEM) was used to observe the petal-like particles in the plate shape and the aggregate thereof, and the thickness of the plate-like particles of any of the 20 plate-like particles or the petal-like particles constituting the aggregate was measured, and the average enthalpy was calculated. Determination. Further, in the present invention, the aspect ratio (average primary particle diameter / average thickness) of the petal-like cerium oxide powder of the plate-like cerium oxide and the aggregate thereof is 2 to 80. When the aspect ratio is less than 2, the obtained cerium oxide powder does not become a plate. Further, when the upper limit 値 80 is exceeded, the thickness of the obtained cerium oxide powder does not become a thickness which retains only the particle shape. The method for producing the petaloid cerium oxide powder of the plate-like cerium oxide of the present invention and the aggregate thereof is a molar ratio of the carbonate ion mixed into sodium carbonate or sodium carbonate to the cerium ion in the cerium nitrate or cerium chloride solution. 1: Within the range of 1.5 to 1:5, the temperature of the mixture is allowed to stand or stir for 30 minutes or longer in the range of 〇~40, and the cerium carbonate particles are precipitated and grown to obtain cerium carbonate octahydrate, followed by burning. Into, a petal-like cerium oxide powder having a plate shape and a collection thereof is produced. (〇~l〇°C is a petal-like cerium oxide which is a mixture of plate-like cerium oxide. When it is 1 〇 to 40 °C, platy cerium oxide can be obtained). The molar ratio of the carbonate ion to the cerium ion is preferably from 1.5 to less than 5 from the viewpoints of the maintenance of the plate-like and petal-like forms and the production efficiency. Carbon-11 - 201210947 When the molar ratio of the acid ion to the cerium ion is less than 1.5, the yield is reduced and the productivity is lowered, and the shape of the plate-like particles becomes irregular. Further, if the molar ratio of the carbonate ion to the cerium ion exceeds 5, the ionic strength is too high and the particles aggregate. The solvent in which the above-mentioned cerium nitrate or cerium chloride, sodium hydrogencarbonate or sodium carbonate is dissolved is water, but may be a mixed solvent containing water. The solvent to be mixed with water may be any compound which is water-soluble, and is preferably an alcohol compound. The alcohol-based compound may, for example, be a monovalent alcohol such as methanol, ethanol, propanol or butanol or a polyvalent alcohol such as polyethylene glycol, ethylene glycol, polyethylene or glycerin. Further, when such an alcohol-based mixed solvent is used, it is preferred that the mass ratio of the alcohol-based solvent to the water in the solvent is less than 50%, more preferably 30% or less. If the mass ratio is 50% or more, sodium hydrogencarbonate or sodium carbonate becomes insoluble, and the uniformity of the obtained petal-like cerium oxide powder in the plate shape and the aggregate thereof is lowered. When the temperature of the mixed liquid is not reached, the progress of the growth reaction of the cerium carbonate particles in the mixed liquid is slow, and the petal-like cerium oxide powder in the form of a plate and an aggregate thereof cannot be obtained in a sufficient yield. . Further, when the temperature of the mixed liquid exceeds 40 ° C, the growth reaction of the cerium carbonate octahydrate particles proceeds rapidly, and the particles become slender and have a needle-like shape. Therefore, the petals of the plate shape and the aggregate thereof cannot be obtained. Oxidized cerium oxide powder. In addition, when the growth time of the cerium carbonate particles is less than 30 minutes, the crystallinity of the obtained cerium carbonate octahydrate particles is deteriorated during the growth of the particles, and amorphous particles are formed, so that the plate shape and the shape cannot be obtained. Petal-like cerium oxide powder of its aggregate. 8 -12- 201210947 Further, the conditions for firing the petaloid strontium carbonate octahydrate particles in the plate shape and the aggregate thereof are preferably in the range of 35 ° C to 1000 ° C, more preferably 400 ° C ~ 7 ° ° C range. When the firing temperature is less than the lower limit 値 350 °C, it does not oxidize at all, and there is a tendency for strontium carbonate octahydrate to remain. If the firing temperature exceeds the upper limit 値1 〇〇〇 °C, there is a tendency to perform sintering between particles. Further, the firing time is preferably in the range of 0.5 to 5 hours. Next, the hydrophobic plate-like cerium oxide powder of the present invention and the petal-like cerium oxide powder of the aggregate thereof will be described. The hydrophobic plate-like cerium oxide powder of the present invention and the petal-like cerium oxide powder system of the aggregate thereof are on the surface of the petal-like cerium oxide powder of the above-mentioned plate-like shape and aggregate thereof, by the aforementioned polyfluorene A compound such as an oxane, an alkyl decane compound, an alkyl titanate compound, or a fluorine compound is subjected to surface coating treatment. Further, various surface treatments conventionally known can be carried out in addition to the above compounds. Moreover, these processes can also be used in combination. Further, in the treatment method in which the hydrophobic compound is subjected to the coating treatment, the coating-treated pigment is generally stirred in a suitable mixer, and the surface-coated compound is added dropwise or sprayed, and then stirred at a high speed for a certain period of time. Thereafter, the mixture was heated and aged at 80 to 200 ° C while continuously stirring, and subjected to a reaction surface coating treatment. Alternatively, for example, a compound coated with a surface may be dissolved in an alcohol such as ethanol, isopropanol or isobutanol, a hydrocarbon-based organic solvent such as toluene, n-hexane or cyclohexane, or acetone, ethyl acetate or butyl acetate. After the polar organic solvent or the like is added to the solution, the pigment for stirring the cosmetic is added to the solution, and the organic solvent is completely evaporated and removed. Thereafter, the mixture is heated and aged at 80 ° C to 2 ° C, and the reaction surface is coated. Method and so on. -13- 201210947 Also, the method of mixing and dispersing is in accordance with the appropriate method of concentration of the solution. A suitable example is a method in which a disperser LODIGE mixer, a kneader, a V-type mixer mill, a biaxial kneader, and the like are used as a mixer; sprayed in a heated air to remove water at a time, and when pulverized, A general pulverizer such as a hammer crusher or a jet mill can be used. Even if it is possible to obtain the same quality, the mass ratio of the surface coating for the pigment to the coating treatment should be such that the mass ratio is less than 0.5% by mass. The effect of the continuous effect is not sufficient. If it exceeds 30% by mass, the touch is not good, and the cosmetic material is not good. Next, the cosmetic material relating to the present invention will be described. By blending the above-described plate shape of the present invention and its aggregate powder, it has an excellent ultraviolet shielding effect. In addition, the petal-like cerium oxide powder system of the aggregate has an average of cerium oxide, so that the cosmetic material blended with the powder is a conventional cosmetic material, and the dosage form of the touch-sensitive cosmetic material applied to the skin can be used.
