Abstract: The invention relates to a method for the therapeutic treatment of keratinous substrate, mucous membrane or tooth comprising preparing a composition containing water, at least one therapeutically active ingredient, an organopolysiloxane X having at least two silicon-bonded alkenyl groups per molecule, a hydrosilylation catalyst and an organohydrogensiloxane compound Y having at least two silicon bonded hydrogen atoms per molecule. At least one of compound X or Y is enclosed within microcapsules suspended in an aqueous phase, and the composition is applied in a galenic form preferably chosen from spray, foam, brush, pen or roller so that a hydrosilylation reaction between compounds X and Y occurs to form a film on the keratinous substrate, mucous membrane or tooth. The invention further extends to a delivery system and to a film comprising a cured silicone.

Abstract: Amphiphilic organosiloxane block copolymers and methods for making them are disclosed. The compositions incorporate an amphiphilic “linear” segment with a “resinous” segment. For example, a polyether (A) modified PDMS (B) with (AB)n architecture and polydiorganosiloxane with Si—H end-groups can be reacted with a phenyl silsesquioxane resin bearing vinyl functionality to form an amphiphilic resin-linear copolymer.

Abstract: This invention pertains to a construction consisting of in the order from the outside towards the inside: An occlusive or non occlusive external film layer; a non-curing pressure sensitive adhesive (PSA) that has been blended with a therapeutic concentration of at least one or a combination of cosmetic or pharmaceutical active ingredients; and a silicone gel adhesive that is used as the skin contact layer.
