Abstract
A foamable aerosol preparation for use as the base of cosmetics, quasi drugs, drugs, and so forth, which comprises 0.1 to 5 w/v % of a surfactant, 0.05 to 10 w/v % of a lower alcohol and/or a glycol, 3 to 25 w/v % of water, and 60 to 95 w/v % of n-butane gas. Despite of the use of n-butane gas as the propellant, this preparation foams very well and is excellent in cracking sound when applied to skin. Furthermore it is particularly useful from the viewpoint of environmental protection, because it is free from the problem of the depletion of the ozonosphere by virtue of the use of a liquefied petroleum gas as the propellant instead of fluorocarbon gas heretofore used.
