This application concerns the use of at least one oligomer chosen from among homopolymers or copolymers of ethylenically unsaturated monomers and polycondensates, having a mean molecular weight measured at the peak top by steric exclusion chromatography ranging from 400 to 10000 and having a vitreous transition temperature ranging from -80 to 10°C, as a plasticizer of a film-forming polymer in and for the preparation of a cosmetic or dermatological composition containing at least this film-forming polymer; the said composition not containing any film-making polymer of the nitrocellulose type. This application also concerns topical formulations containing these plasticizers, including capillary compositions for styling, maintenance and setting of hair and make-up compositions.
La présente demande concerne l'utilisation d'au moins un oligomère choisi parmi les homopolymères ou copolymères de monomère(s) à insaturation éthylénique et les polycondensats, ayant un poids moléculaire moyen mesuré en sommet de pic par chromatographie par exclusion stérique allant de 400 à 10000 et ayant une température de transition vitreuse allant de - 80 à 10°C, comme agent plastifiant d'un polymère filmogène dans et pour la préparation d'une composition cosmétique ou dermatologique contenant au moins ce polymère filmogène; ladite composition ne contenant pas depolymère filmogène du type nitrocellulose. La présente demande concerne aussi les formulations topiques contenant ces agents plastifiants notamment les compositions capillaires pour le coiffage, pour le maintien et/ou la fixation de la chevelure et les compositions de maquillage.
