Abstract

The present invention relates to a self-foaming, self-leveling aqueous liquid composition packagable in a non-pressurized deformable dispenser of flexible barrier material adapted to contain, maintain and dispense a proportioned amount of the cleansing composition under positive pressure. The composition comprises: a major amount of water; a surfactant; and a dual purpose pressure agent comprising at least one aliphatic hydrocarbon fluid in amounts sufficient to provide the liquid composition, which when contained in a dispenser exerts a positive vapor pressure at least at about 1.6.degree. C. The composition is dispensed as a liquid under normal operating conditions, which liquid foams instantaneously and spontaneously on spreading.
