CA 2285285

The invention concerns a method for making a product adhere to a surface, characterized in that it consists in contacting with said surface a composition wherein said product is incorporated in substantially spherical multilamellar vesicles, with a diameter between 0.1 and 100 µm, consisting of concentric membranes based on at least a surfactant separated by a solvent medium, said vesicles having an onion-like structure and bearing a global positive charge related to the presence of at least a cationic agent within said vesicles. The surface to be treated can be either an inert surface, for instance a fiber or an assembly of fibers such as a fabric, or a biological surface such as the skin, the hair, hairs, superficial body growth, the cuticle of living beings or the cuticle of plants.

L'invention concerne un procédé destiné à faire adhérer un produit sur une surface, caractérisé en ce qu'il consiste à mettre en contact avec ladite surface une composition dans laquelle ledit produit est incorporé dans des vésicules multilamellaires sensiblement sphériques, de diamètre compris entre 0,1 et 100 µm, constituées de membranes concentriques à base d'au moins un tensioactif séparées par un milieu solvant, lesdites vésicules présentant une structure en oignon et portant une charge globale positive liée à la présence d'au moins un agent cationique au sein desdites vésicules. La surface à traiter peut être aussi bien une surface inerte, par exemple une fibre ou un ensemble de fibres tel qu'un tissu, qu'une surface biologique telle que la peau, les cheveux, les poils, les phanères, la cuticule des êtres vivants ou la cuticule des plantes.
