Abstract
A stable, oil-in-water macroemulsion cleaner is provided which has low toxicity, rapid evaporation rate and leaves low residue after use. The cleaner comprises perchloroethylene, water, ethanol and/or ethyl acetate, and non-ionic surfactant. The macroemulsion cleaner can be used to remove greasy and oily soils from soiled surfaces, and is non-flammable as an aerosol spray with appropriate propellant formulations.
