Abstract: The present invention relates to an oily dispersion (A) comprising i) at least one particle consisting of an ethylenic polymer, ii) at least one polymeric stabilizer comprising a (C9-C22)alkyl group, and iii) at least one hydrocarbon-based fatty substance which is liquid at 20° C. and 1 atmosphere. The invention also relates to a process for treating keratin materials, notably human keratin materials such as the skin or the hair, involving the application to said materials of at least one oily dispersion (A); to a process for preparing the oily dispersion, and to a multi-compartment kit comprising ingredients i) to iii). The oily dispersion (A) and the process for treating keratin materials as defined above make it possible to obtain a treatment for said materials which is notably resistant to shampoo washing, to sebum, to sweat and/or to water, but also to fatty substances, notably dietary fatty substances such as oils.

Abstract: The present invention relates to an aqueous dispersion of polyalkene supramolecular polymer with a surfactant system chosen from an anionic surfactant, a cationic surfactant and a non-ionic surfactant. The invention also relates to a cosmetic composition comprising such a dispersion. Use for caring for and making up keratin materials.

Abstract: The present invention relates to a cosmetic composition with a liquid fatty phase, comprising, in a physiologically acceptable medium, at least one liquid fatty phase, in which the said phase is textured with an effective amount of at least one asymmetric bis-urea compound of defined formula.

Abstract: Novel water-soluble or water-dispersible amphiphilic cationic associative polymers, a process for preparing them and their use in compositions for topical application, such as for cosmetic use, as thickeners, and the compositions comprising these polymers.

Abstract: The invention relates to a keratin fibre makeup composition having a solids content of more than 45% of the total weight of the composition; and a rheological profile such that, for a shear gradient range from 10?2 to 103 s?1, the ratios of the change in shear gradient to the change in applied shear stress (the said ratio being written ?{dot over (?)}/??) are not more than 7; the said composition being capable of undergoing shear stresses without breaking up over the entire breadth of the said shear gradient range. The invention allows a smooth and continuous deposition of product on the fibre.
