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.

AI Technical Summary

Benefits of technology

The present invention provides a safe and effective insecticide composition that can be used to treat or prevent infestation by parasites like arthropods. The composition contains a second insecticide, such as a plant-derived oil, and a potent solvent. The invention also includes a therapeutic kit with an aerosol packaging assembly for easy use.

Problems solved by technology

Occasionally, a skin infection develops following a bite.

Scratching as a result of insect bites can damage the skin and allow bacteria to get in.

Infection causes redness and tenderness around the bite, which may gradually spread, and sometimes can become serious.

A common way to overcome resistance is to add a secondary active agent, which impedes that resistance mechanism.

However, this product possesses at least four disadvantages: (1) Irritability: due to the high alcohol content, the incidence of skin and eye irritation is high; (2) “Quick breaking” property: the foam is thermo-sensitive and breaks down rapidly at body temperature so that is cannot easily bespread manually throughout the scalp area; (3) Skin drying; and (4) Inflammability: 26.3% alcohol renders the foam inflammable.
