ABSTRACT:
Novel compositions for topical application of a water-insoluble bioactive reagent, e.g. a pesticide, comprising an aqueous emulsion of a polymer swellable by the sebum and other "skin oils" and which will agglomerate or coagulate near the skin, the polymer having the bioactive agent encapsulated or dispersed therein; and novel methods employing the same for controlled release of the bioactive reagent over an extended period of time.
