An aqueous composition comprising, in addition to water: (a) one or more surfactant materials selected from polyoxyalkylene condensate derivatives of lanolin or a lanolin derivative; and (b) a lipid component comprising one or more lipid materials, especially lanolin or a lanolin derivative, present as particles emulsified by the said one or more lanolin-derived surfactant materials and having a median particle size of less than about 5 µm, especially from 0.01 to 1 m. The compositions have very good physical stability and are particularly useful as carriers for transdermal delivery of pharmaceutical actives to the human skin.
Dans la présente invention, on divulgue une composition aqueuse comprenant, en plus de l'eau : a) une ou plusieurs substances tensioactives sélectionnées parmi des dérivés de condensat de polyoxyalkylène de lanoline ou un dérivé de lanoline; b) un composant lipidique comprenant une ou plusieurs substances lipidiques, notamment la lanoline ou un dérivé de lanoline, présente sous forme de particules émulsifiées par lesdites substances tensioactives dérivées de lanoline et ayant une granulométrie moyenne inférieure à environ 5 m, notamment comprise entre 0,01 et 1 m. Ces compositions ont une très bonne stabilité physique et sont particulièrement utiles comme excipients dans l'administration transdermique de substances pharmaceutiques actives.
