Abstract: A cleaning composition being an oil-in-water emulsion in aerosol form characterized in that sufficient of the propellant is retained in the emulsion on discharge to a surface such that the retained propellant boils to create a sustained bubbling action in the absence of foaming on the surface. The cleaning composition comprises an oil-in-water emulsion containing (a) 2 to 60% w/w in total amount of one or more hydrocarbon propellants such that the propellants substantially form a part of the oil phase when the composition is formulated; (b) 2 to 50% w/w in total amount of one or more surfactants; (c) 0.1 to 30% w/w in total amount of one or more water-immiscible organic compounds; (d) 0.5 to 40% w/w in total amount of one or more water-miscible organic coupling agents; and (e) 10 to 70% w/w of water.
