Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a titanate nanosheet dispersion excellent in transparency that has few contents of ammonium compounds, phosphonium compounds and amines, the titanate nanosheet dispersion and a titanate nanosheet solid. SOLUTION: (1) The method for producing a titanate nanosheet dispersion has the step where a titanium source is hydrolyzed in the presence of quaternary ammonium hydroxide or the like and amines to obtain an aqueous titanate nanosheet dispersion and then a part or all of the obtained aqueous dispersion is replaced with an organic solvent to obtain an organic solvent dispersion, which is mixed with a dispersing agent, followed by contacting the obtained dispersion with a cation-exchange resin. (2) The titanate nanosheet dispersion obtained in the method has a molar concentration ratio ([N]/[Ti]) and/or ([P]/[Ti]) (wherein [N], [P] and [Ti] indicate molar concentrations of a nitrogen atom, a phosphorus atom and a titanium atom respectively) less than 0.2. (3) The titanate nanosheet solid is obtained by removing a dispersion medium from the titanate nanosheet dispersion. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To obtain a red pigment controlled in the spectral reflectance of the pigment itself and being capable of controlling the spectral reflectance of a cosmetic containing the pigment by using a complex oxide of Ca and Fe. SOLUTION: This pigment comprises a double oxide of the formula: Cax Fey Ox+(3y/2) (wherein x is 0.6-2; and y is 2-3). By controlling the deflection point wavelength (the wavelength at which the first-order differential derivative function of a spectral reflectance curve has a maximum volue or the second- order differential derivative function shows 0) of a spectral reflectance curve obtained by measuring the spectral reflectance of the pigment to 600-640nm, e.g. a cosmetic containing this pigment gives a spectral reflectance curve having a hollow in a wavelength region of 500-620nm. The healthy skin gives a spectral reflectance curve having a hollow at a wavelength of 500-620nm, whereas the darkish skin gives a spectral curve having a shallow hollow at 500-620nm. Therefore, the compound oxide in an amount to give a concentration of 5wt.% is mixed with a body pigment to obtain a red pigment which gives a spectral reflectance curve having a hollow at 500-620nm.

CONSTITUTION:An alkali solution is added under vigorous stirring so as to keep pH to >=11 to a solution obtained by dissolving 0.005-1.0mol salt containing one or more elements selected from iron, zirconium, calcium, germanium, manganese or yttrium or zinc and 0.05-1.0mol water-soluble alkali metal salt into water for 1-300sec, based on 100mol zinc salt to produce precipitate. As necessary, the precipitate is subjected to aging treatment at 60-100 deg.C for 30min to 5hr and washed with water, filtered to collect the precipitate and the precipitate is dried at 200-300 deg.C for 1-20hr. Thereby, laminar oxide zinc powder having 0.1-1mum average particle diameter and 0.005-0.2mum average particle thickness and >=3 average plate ratio and a trace element bound and retained on the surface or in the interior of the zinc oxide powder and integrated with the zinc oxide powder are included in the powder.

Abstract: PURPOSE:To stably and continuously obtain a salt hardly soluble in water and of a uniform size by circulating a part of the produced slurry to a tube reactor when the salt hardly soluble water is produced by continuously supplying two or more kinds of source materials to the tube reactor to effect the reaction. CONSTITUTION:Two or more kinds of source materials are contiuously supplied from the source material tanks 11, 12 to a tube reactor 6 where the source materials are mixed to effect the reaction to produce the salt hardly soluble in water. The produced slurry is reserved in a liquid reserving tank 15. In this process, a part of the produced slurry containing the salt discharged from the reactor 6 is circulated to the source material or the reactor 6 by using a slurry pump 16. Thus, the salt hardly soluble in water is produced in the presence of the produced slurry. Thereby, even when a salt hardly soluble in water and having a high reaction rate is to be produced by the reaction, such a salt having uniform particle size and crystal shape and suitable as a pigment, such as barium sulfate, can be continuously produced.
