Publication number: 20240099959Abstract: The present invention is to provide an oil-in-water type lip cosmetic having an excellent secondary adhesion-less effect and excellent in gloss feeling, and fit feeling for the lips and fresh. Oil-in-water type lip cosmetic excellent not only in secondary adhesion-less effect but also in gloss feeling and fit feeling is obtained by combining a dimethyl silicone oil having a particular viscosity with a film-forming agent including a hydrocarbon-based polymer incompatible with the silicone oil.Type: ApplicationFiled: September 13, 2021Publication date: March 28, 2024Applicant: Shiseido Company, Ltd.Inventors: Mika KONDO, Kyohei KOSAKA, Akiko FUKUI, Ayumi ASAI, Kiriko CHIBA, Ayano KIGAWA

Publication number: 20190076342Abstract: An aqueous cosmetic composition provides a proper amount of a hydrophobic spherical powder blended in an aqueous phase stably even though an aqueous base material having a fresh sensation upon use is used, and which corrects the appearance of skin. The present invention provides a cosmetic composition characterized by comprising (A) at least one higher alcohol having a saturated straight alkyl chain, (B) hydrophilic surfactants including a nonionic surfactant, (C) a powder having an average particle diameter of 1 to 30 ?m in an amount of 4 to 30% by mass and (D) water, wherein the ratio of the number of moles of a hydrophilic nonionic surfactant to the total number of moles of the hydrophilic surfactants (B) is 0.5 or more, the percentage of the amount of a hydrophobic spherical powder in the total amount of the powder having an average particle diameter of 1 to 30 ?m (C) is 50% by mass or more, and the hydrophobic spherical powder is added to an aqueous phase.Type: ApplicationFiled: February 28, 2017Publication date: March 14, 2019Applicant: SHISEIDO COMPANY, LTD.Inventors: Ayumi ASAI, Akinori ONO

Patent number: 8778363Abstract: To provide an oil-in-water emulsion skin care cosmetic composition which, without the addition of a pharmaceutical agent and a film-forming agent or the like thereto, effects an excellent elastic or resilient feeling to skin and is excellent in non-stickiness and stability. An oil-in-water emulsion skin care cosmetic composition, comprising (a) a paraffin wax and/or a polyethylene wax, (b) a microcrystalline wax, and (c) an animal/plant-derived wax which contains, as the main ingredient thereof, an ester of a higher fatty acid having from 20 to 32 carbon atoms and an alcohol having from 28 to 34 carbon atoms, and has a melting point of from 75 to 100° C., in which the ratio of component (a) to component (b) is from 70/30 to 95/5 (by mass).Type: GrantFiled: December 16, 2009Date of Patent: July 15, 2014Assignee: Shiseido Company, Ltd.Inventors: Rie Yamamoto, Kazuhiko Fujiwara, Ayumi Asai, Tomomi Furukawara

Patent number: 8765821Abstract: The invention provides an oil-in-water type cosmetic emulsion which can be applied to the skin without stickiness, and impart resilient and supple feel to the skin, while having good stability without causing viscosity decrease or separation even during a long-term storage. The oil-in-water type cosmetic emulsion comprises (a) a higher alcohol having 14 to 22 carbon atoms, (b) a hydrophilic polyoxyethylene alkyl ether, and (c) a glycerin monoalkyl ether, wherein alkyl moieties in (b) and (c) are linear saturated alkyl chains, and molar concentrations of (a) to (c) satisfy a relation [(b)+(c)]/(a)=0.1 to 1.0, and preferably satisfy a relation [(a)+(c)]/(b)=3 to 20.Type: GrantFiled: March 11, 2009Date of Patent: July 1, 2014Assignee: Shiseido Company, Ltd.Inventor: Ayumi Asai
