ABSTRACT:
A microsuspension system containing insect repellent is disclosed that includes lipospheres, that are solid, water-insoluble microparticles that have a layer of a phospholipid embedded on their surface. The core of the liposphere is a solid insect repellent, or an insect repellent dispersed in an solid vehicle, such as a wax. Insect repellents include compounds that repel insects, are insecticidal, or regulate or inhibit insect growth on humans and other animals and plants. Insect repellent lipospheres provide controlled release of insect repellents while minimizing absorption through the skin.
