Abstract
A sprayable cosmetic product is provided packaged in a clear bottle capable of withstanding at least 5 psig pressure fitted with a spray nozzle. The cosmetic composition contained therein is a clear, single-phase fluid containing a dialkyl ether/hydrocarbon as propellant system and a concentrate which requires a surfactant and optimally may contain a coupling agent. When present, the coupling agent is a propoxylated adduct of mono or polyhydric alcohols. Upon activation of the spray nozzle, a thick, creamy mousse is expressed. These compositions will preferably have a pH ranging from about 3.0 to 6.5.
