Abstract: The present invention provides a black brightening flake which prevents fine pigment particles from agglomerating. When incorporated into a cosmetic, a coating material, etc., the flakes enable the resultant composition not only to give a satisfactory use feeling, for example, spreadability on the skin, without giving a rough feeling or be satisfactory spread on a base plate but also to have high hiding power and take on a beautiful color tone. The black brightening flake comprises a metal oxide, as a mother material, which is derived from a colloidal metal oxide particle and 5 to 70% by mass black pigment dispersedly contained in the base material. The black brightening flake has an average particle diameter of 3 to 500 ?m, an average thickness of 0.1 to 5 ?m, and an average aspect ratio of 5 to 300.

Abstract: A porous metal oxide material in a flake form having a specific surface area of 110 to 3000 m2/g, an average particle diameter of 5 to 500 ?m, an average thickness of 0.1 to 5 ?m, and an average aspect ratio of 5 to 300; a method for producing the material which comprises applying a colloid solution containing colloidal particles of the metal oxide having a particle size of 5 to 500 nm on a substrate, drying to solidify the colloid solution, delaminating the resultant solid form the substrate, and subjecting the solid to a heat treatment; and a cosmetic, a coating composition, a resin composition, an ink and a paper sheet comprising the material. The porous metal oxide material in a flake form exhibits functions inherent in a porous material, is free problems such as the reduction of handlability due to coagulation, has a great mechanical strength, and exhibits great holding capability when used as a carrier.

Abstract: Flaky particles suitable for a filler having high durability and high weatherability which absorbs reduced amount of visible light and effectively scatters visible light are provided. By using the flaky particles to be contained, a cosmetic or the like capable of giving good usability such as spreading well on the skin, exhibiting bright and clear appearance for long period is provided. The flaky particles comprise mother particles of metallic oxide of low refractive index and microparticles of metallic oxide of high refractive index having a mean particle size of 160-450 nm dispersed inside the mother particles in an amount of 5-50% by weight, wherein the flaky particles have a light diffusion degree of 80 or more. The flaky particles preferably have a mean particle size of 5-500 ?m, a mean thickness of 0.1-5 ?m, and a mean aspect ratio of 5-300.

Abstract: A cosmetic is provided that contains a powder that exhibits a shininess characteristic of a metal film and yet is not prone to leaching out of metal ions, whereby the cosmetic is not prone to causing discoloration or degeneration, and is not prone to bringing about a metal allergy.

Abstract: In a peeling apparatus of an extrusion material batch, a circular blade is arranged at an outlet portion of a kneader, and an outer surface of the extrusion material batch extruded from the outlet portion is peeled uniformly. It is preferred to arrange a longitudinal blade for cutting the peeled waste materials in a radial direction at a periphery of the circular blade. Since a water content of the peeled waste materials is not varied, they can be returned as they are to the inlet hopper of the kneader via a transfer line.
