<p>The invention provides a simple aerosol package suitable for use with non-liquifiable propellant gases, which dispenses a light foam (preferably less than 200g, more preferably less than 150g), and which can be completely emptied under the pressure of the propellant gas. A packaged product comprises a foaming composition and propellant gas packaged within an aerosol container in which at least 0.5 moles/litre of non-liquifiable propellant gas can be charged into a gas-tight measuring vessel, said vessel containing 60 percent by volume of the foaming detergent composition, when measured at 12 bar at 50 degree C. In a second aspect of the invention a method of cleaning textile fabrics is provided using a packaged product as described above, comprising the steps of: (i) dispensing the foaming composition from the container in the form of a foam having a bulk density less than 250 g/l on to textile fabrics, and (ii) distributing the foam, either by mechanical agitation, or by hand, over the textile fabrics, (iii) removing the foam residue from the cleaned textile fabrics.</p> |
