In a zinc oxide powder of the present invention, a content of a water-soluble substance is 0.30% by mass or less, and a mass ratio between an alkali metal and an alkaline earth metal which are included in the water-soluble substance is in a range of 1:2 to 10:1.

An oil-in-water emulsion cosmetic composition is provided. The cosmetic composition comprises a carboxylic acid modified silicone (A) that is liquid state at 50° C., an oil agent (B), water (C), and an oil-soluble film-forming agent (D). The oil-soluble film-forming agent (D) is present in a range of 0.01 to 5 mass % of the total mass of the cosmetic composition. The cosmetic composition according can provide a cosmetic film with high stability and excellent water resistance.

A method for producing a film of the present invention includes the step of electrostatically spraying a liquid composition directly on the surface of skin using an electrostatic spray device to form a film on the skin. The electrostatic spray device includes a container capable of storing the liquid composition, a nozzle configured to eject the liquid composition, a power supply configured to apply a voltage to the nozzle, and a voltage stabilizer configured to stabilize the voltage applied by the power supply to the nozzle. The liquid composition contains component (a): one or more volatile substances selected from alcohols and ketones, and component (b): a polymer having film formability.

The present invention relates to a particulate highly porous amorphous mesoporous magnesium carbonate material suitable for uptake of high amounts of oily substances, sebum or a beneficial agent or combinations of these and to topical and cosmetic compositions comprising such material. The particulate highly porous amorphous mesoporous magnesium carbonate material according to the invention has a total pore volume larger than 0.1 cm 3/g and is constituted of particles having a peak particle size at or below 35 μm.

The use of a particulate mineral as an anti-pollution agent in a composition for application to skin and/or keratin materials, a method for protecting skin and/or keratin materials from pollution, a composition comprising a particulate mineral and a method of making said composition.

Biodegradable resin particles including a recessed portion in a surface of the particles; and a hollow portion within the particles. The biodegradable resin particles of the present invention can be used in external preparations, such as cosmetics and quasi-drugs; coating materials, such as powder coating compositions and matting agents for coating compositions; rheology modifying agents; anti-blocking agents; smoothing agents; light-diffusing agents; additives for advanced ceramics sintering; fillers for adhesives; and agents for medical diagnosis and examination and can also be used by being added to a resin composition for automotive materials, construction materials, or the like or to a molded product thereof. In particular, the resin particles can be suitably used by being included in an external preparation, examples of which include cosmetics and quasi-drugs; a coating material, examples of which include powder coating compositions and matting agents for coating compositions; or an anti-blocking agent for packaging materials for food and drink or the like.
