Abstract: One subject of the present invention is in particular an anhydrous cosmetic composition comprising: i) at least 30% by weight, relative to the total weight of the composition, of one or more branched alkanes having from 8 to 16 carbon atoms; ii) 5 to 15% by weight, relative to the total weight of the composition, of one or more dimethiconols; iii) one or more amino silicones; iv) one or more silicones different from the dimethiconols ii) and the amino silicones iii); and v) optionally one or more non-silicone fatty substances which have a melting point of less than or equal to 25° C. and are different from the branched alkanes i), the water content being of less than or equal to 4% by weight, relative to the total weight of the composition.

Abstract: The present disclosure relates to a cosmetic composition and hairstyling method comprising, in a cosmetically acceptable aqueous medium: (i) at least one cationic polyurethane comprising at least one non-ionic unit derived from at least one polymer chosen from olefinic homopolymers and copolymers, and (ii) at least one silicone chosen from polydialkyl siloxanes and organomodified polysiloxanes comprising at least one functional group chosen from poly(oxyalkylene), amine and alkoxy groups.

Abstract: The present disclosure relates to a cosmetic composition comprising, in a cosmetically acceptable aqueous medium: (i) at least one cationic polyurethane comprising at least one non ionic unit derived from an olefinic homopolymer and/or copolymer, and (ii) at least one vinyl pyrrolidone homopolymer or copolymer.

Abstract: The present disclosure relates to a cosmetic composition comprising in a cosmetically acceptable medium: (i) at least one cationic polyurethane comprising at least one non-ionic unit derived from at least one polymer chosen from olefinic homopolymers and copolymers, and (ii) at least one polyethylene glycol ester. The present disclosure relates to a method for treating hair using the compositions herein defined.

Abstract: The present disclosure relates to a hair cosmetic composition, such as a gel, comprising at least one high-molecular-weight polyurethane polymer and at least one thickener. The present disclosure also relates to a hair cosmetic method comprising the application of said composition to the hair and its use to fix and/or hold the hairstyle.

Abstract: Disclosed herein is a composition for cosmetic treatment of keratin materials, packaged in an aerosol device comprising (a) at least one propellant and (b) a hairstyling composition comprising at least one polyurethane having a number-average molecular weight ranging from 400 000 to 5 000 000 g/mol, in a cosmetically acceptable medium comprising water. Also disclosed herein is an aerosol device comprising the composition disclosed herein.

Abstract: Disclosed herein is a styling cosmetic composition comprising, in a cosmetically acceptable medium predominantly comprising water, at least one cationic polyurethane of elastic nature. Also disclosed are cosmetic treatment processes for shaping or holding the hairstyle comprising applying the styling cosmetic composition to the hair. There are also disclosed methods of shaping or holding the hair comprising applying the composition to the hair, such that the resulting hair exhibits at least one property chosen from persistence over time and resistant to moisture.

Abstract: Cosmetic compositions comprising, in a cosmetically acceptable medium: (1) at least one film-forming polymer (A), wherein a film obtained by drying a mixture of said polymer (A) with ethanol or water, at room temperature and at a relative humidity of 50%, has a mechanical profile defined by at least: (i) a degree of elongation at break (&egr;r) of greater than or equal to 300%; (ii) a recovery at 300 seconds (R300) of greater than or equal to 45%; and (iii) if the recovery at 300 seconds (R300) is from 45% to 60%, then the elongation at break is less than or equal to 1300%; and (2) at least one crosslinked thickening polymer (B) comprising at least one (meth)acrylic acid monomeric, wherein said at least one polymer (B) is present in the composition in an amount ranging from at least 0.6% by weight, relative to the total weight of the composition.
