AEROSOL PREPARATION FOR EXTERNAL USE

摘要

The present invention provides a new aerosol preparation for external use mainly directed to skin cooling, which forms sherbet-like foams when sprayed. The stock solution is composed of a mixture of water with a lower alcohol as the base and a mixture of liquefied petroleum gas with dimethyl ether as the propellant, blended in a specified compositional ratio so as to form sherbet-like foams. This aerosol preparation is expected to exhibit a combined effect of the aerosol preparation as the coolant and the main ingredient as the drug. It is especially excellent in its application to the affected part of a human body as compared with the conventional aerosol preparations for external use which are sprayed as droplets.
