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.

Dependent claims

A non-foaming textile cleaning composition in the form of an aerosol-containing oil-in-water emulsion comprising:

(a) 5 to 50% w/w in total amount of one or more hydrocarbon propellants, wherein the propellants substantially form a part of the oil phase when the composition is formulated;
(b) 5 to 25% w/w in total amount of a surfactant system consisting of anionic surfactants, nonionic surfactants and mixtures thereof;
(c) 0.5 to 30% w/w in total amount of one or more water-immiscible hydrocarbon solvents selected from the group consisting of liquid n-paraffins, liquid isoparaffins, cycloalkanes, kerosene, white spirit, toluene, benzene and xylene;
(d) 5 to 30% w/w in total amount of one or more water-miscible organic coupling agents selected from the group consisting of methanol, ethanol, n-propanol, isopropanol, n-butanol and isobutanol;
and
(e) 10 to 70% w/w of water;
in which, upon discharge of the composition to a surface, a sufficient amount of the propellant is retained in the emulsion such that the retained propellant boils to create a sustained bubbling action on the surface.
