    摘要: A cosmetic composition comprising Janus particles, an aqueous phase and an organic phase uses Janus particles produced with a method which includes the preparation of hollow particles (1) having two non-continuous surfaces of a material with surface energy a, of which the external one (2) is accessible and the internal one (3) is inaccessible. The surface energy of the external surface (2) is thereby modified originating particles (11) with internal surface energy a and external surface energy 13. The modified particles (11) are then ground until particles are obtained constituted by small fragments (21) shaped as spherical caps with external surface (12) having modified energy and internal surface (13) having non-modified internal energy.

    摘要: A non-rinse-off hair protective cosmetic including a polyoxyalkylene-modified organopolysiloxane compound which has: a terminal to which a siloxane chain having a polyoxyalkylene group shown by a formula (1) is bonded; 50 or more structural units shown by a formula (2) per molecule; a viscosity of 50,000 mPa·s or more at 25° C.; and an HLB of 1 to 7, where each R1 represents an alkyl group or a phenyl group; A represents a monovalent group having a polyoxyalkylene group shown by a formula (3) or (4). Thus, a non-rinse-off hair protective cosmetic excellent in hair protection performance, resistant to water, but easily removable with a shampoo or the like after use.

    摘要: The present invention relates to an organopolysiloxane graft polymer including an organopolysiloxane segment as a main chain thereof and an unsaturated monomer-derived copolymer segment containing a repeating unit derived from an unsaturated monomer containing a carboxylic acid or a carboxylic acid salt as a side chain thereof, in which a content of the organopolysiloxane segment in the organopolysiloxane graft polymer is 35 to 59% by mass, a content of the repeating unit derived from the unsaturated monomer containing a carboxylic acid or a carboxylic acid salt in the organopolysiloxane graft polymer is 4 to 17% by mass, and a content of a repeating unit derived from an unsaturated monomer whose homopolymer has a glass transition point of not lower than 150° C. (except for the unsaturated monomer containing a carboxylic acid or a carboxylic acid salt) in the organopolysiloxane graft polymer is not more than 14% by mass, and a number-average molecular weight of the organopolysiloxane segment is not less than 8,000 and not more than 200,000.
