Abstract:
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.
