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.
