摘要：
An aqueous dispersion, useful for forming a film, comprises a silicone composition dispersed in an aqueous phase. The silicone composition comprises a product of a reaction of (a) an alkenyl-containing organopolysiloxane having an average per molecule of at least 2 alkenyl groups and (b) an Si H containing siloxane having an average per molecule of at least 2 Si H moieties. The dispersion also comprises a hydrosilylation catalyst and polyvinyl alcohol. The composition is stabilised in dispersion form by the polyvinyl alcohol dissolved in the aqueous phase. The dispersion is an effective method of delivering a pharmaceutically or cosmetically active ingredient by topical application.
