USE OF POLYMERS HAVING A CRITICAL TEMPERATURE OF THE LCST TYPE OR OF THE UCST TYPE IN AND FOR THE MANUFACTURE OF COSMETIC OR DERMATOLOGICAL FORMULATIONS CONTAINING THEM

摘要

The invention relates to the use as a coating agent of keratin materials in and for the preparation of cosmetic or dermatological compositions of a hydroorganic solution comprising at least (a) a non-crosslinked polymer capable of forming a deposit or a film on a keratinous support after drying and having a critical temperature Tc of solubility in water of the LCST or UCST type ranging from 0degre to 100degreC and (b) at least one total organic solvent of said polymer in the temperature range of use of the composition , partially or totally miscible with water and more volatile than water; especially in styling and / or hair-holding products or in makeup products, in particular aqueous nail varnishes. The invention also relates to the use as a coating agent of keratin materials in and for the preparation of compositions. cosmetic or dermatological of an aqueous solution or an aqueous dispersion containing the combination of at least one polymer as described above and at least one surfactant and / or a hydrophilic polymer, capable of establishing physical interactions with said polymer, in particular in styling shampoos and / or conditioners.
