Patent

CA 2586040

The invention relates to a polymer for topical delivery of biologically active ingredients, the polymer comprising at least on moiety: U-B-A, in which U represents a physiologically acceptable unit of an oligomer or polymer, A represents a biologically active component, and B represents one or more bond(s) linking A to U, which bond is capable of being disrupted by a biological, physical or chemical process occurring in the skin.

L'invention concerne un polymère permettant l'application par voie topique d'ingrédients biologiquement actifs, ledit polymère contenant au moins un fragment U-B-A, dans lequel U représente une unité acceptable d'un point de vue physiologique d'un oligomère ou d'un polymère, A représente un composant biologiquement actif, et B représente une ou plusieurs liaisons entre A et U, lesdites liaisons pouvant être interrompues par un processus biologique, physique ou chimique se produisant dans ou sur la peau.
