The report provides technical assistance to aerosol product marketers and fillers in other nations now faced with eliminating chlorofluorocarbons (CFCs) under the terms of the Montreal Protocol. It addresses the issues of hydrocarbon propellant supply, product reformulation, equipment conversion, and safety concerns for both the manufacturing plants and the aerosol products themselves. Because stratospheric ozone provides protection from biologically damaging ultraviolet-B radiation, and because CFCs have been strongly implicated in the thinning of the Earth's stratospheric ozone layer, there is an urgent need to eliminate production and use of the CFCs. In the U.S., CFCs were banned for use as propellants from nearly all aerosol products as early as 1978. In place of the CFC propellants, liquified hydrocarbons such as propane, n-butane, and isobutane were found to be acceptable substitutes for most aerosol products.
