ABSTRACT:
Liquefiable powder compositions are disclosed for the delivery of topical insect repellents. In particular, microporous cellulosic powders, such as cellulose acetates or nitrates, are disclosed as high liquid content vehicles for the delivery of liquid insect or tick repellent preparations. The resulting powders permit the application of the arthropod repellent preparation by simply rubbing or brushing the formulation onto the skin, in such a manner that the powder liquefies and appears to vanish. Upon application, the frangible, liquid loaded cellulosic powders break up into minute particles that do not pass easily beyond the initial layers of the skin, but do permit the slow release of the insect repellent agent.
