Abstract: An oil-in-water emulsion composition for skin includes 0.2 to 2.5% by mass of polyisobutene having a relative mass in a range of 30,000 to 100,000. The composition is applied to skin except for a lip.

Abstract: A vehicle includes a center differential device and an air pressure controller. The center differential device includes a first output shaft coupled to front wheels and a second output shaft coupled to rear wheels. The center differential device is configured to perform differential operation between the first output shaft and the second output shaft and to limit the differential operation between the first output shaft and the second output shaft. The air pressure controller is configured to control air pressure of one or more tires of the front wheels and the rear wheels such that an average rotational speed of the front wheels and an average rotational speed of the rear wheels are equal to each other.

Abstract: An objective of the present invention is to provide a retinol-containing oil-in-water emulsion cosmetic that has excellent emulsion stability while stably retaining retinol, that also has a good fitting sensation when applied, and that has a watery and fresh feeling in use. The present invention pertains to an oil-in-water emulsion cosmetic containing (a) retinol; (b) an alkyl-modified carboxyvinyl polymer; and (c) an oil, wherein a blended amount of the (c) oil is 10% to 40% by mass relative to a total amount of the cosmetic, and the (c) oil contains at least 50% by mass of an ester oil relative to a total amount of the oil.

Abstract: A solid or semi-solid water-in-oil type emulsion cosmetic has a hardness that can be balm-like, the cosmetic has an excellent moisturizing effect, exhibiting upon use a unique sensation of blending as if melting when applied to skin, and is capable of stably incorporating a water-soluble or hydrophilic drug. A water-in-oil type emulsion cosmetic contains: (A) an organically modified clay mineral; (B) a surfactant having an HLB of no more than 6; (C) a wax; (D) a silicone elastomer; (E) a volatile oil; and (F) water.

Abstract: An oil-in-water emulsion composition includes component (A): from 0.1 to 5% by mass of a hydrophilic nonionic surfactant, component (B): more than 0.02% by mass to less than 0.5% by mass of an anionic surfactant, component (C): from 0.5 to 6% by mass of a higher alcohol, and component (D): from 2 to 30 mmol/100 g of an organic acid and/or a salt and/or derivative thereof. The component (A) includes a polyoxyalkylene alkyl ether and/or a polyalkylene glycol fatty acid ester.
