Abstract (en)
[origin: FR2911781A1] A gelled foaming composition (I) in the form of a stable oil-in-water (O/W) micro-emulsion comprising an oil phase of micro-droplets dispersed in an aqueous phase plus a dermatological active ingredient (II), also contains a surfactant system comprising (a) ethoxylated non-ionic surfactant(s), (b) co-surfactant(s) stabilising (a), (c) non-ethoxylated hydrophilic non-ionic surfactant(s) and (d) foaming agent(s) selected from anionic surfactants. An independent claim is also included for a method for the preparation of (I) by mixing the oil phase with the surfactant system and homogenising by mechanical stirring, mixing the various adjuvants (e.g. thickener) with the aqueous phase, mixing the two phases at a stirrer speed and temperature sufficient to give a transparent composition, possibly adjusting the pH with acid or base and then incorporating the active ingredient to obtain complete dissolution at room temperature.
