Title:	Foamable composition and uses thereof
Abstract:	The present invention provides a safe and effective insecticide composition suitable for treating a subject infested with a parasitic anthropode or to prevent infestation by an arthropod. The insecticide composition is a foamable composition, including a first insecticide; at least one organic carrier selected from a hydrophobic organic carrier, a polar solvent, an emollient and mixtures thereof, at a concentration of about 2% to about 5%, or about 5% to about 10%; or about 10% to about 20%; or about 20% to about 50% by weight; about 0.1% to about 5% by weight of a surface-active agent; about 0.01% to about 5% by weight of at least one polymeric agent selected from a bioadhesive agent, a gelling agent, a film forming agent and a phase change agent; and (5) a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the total composition.
