	I would be interested in knowing *exactly* what the Candian version
of "Pam" states on its ingredient listing.  There may be a different
formula for the Candian market.

	There are no alcohols which are propellants, and any alcohols listed
would be solvents for the corn oil and lecithin.  There are comparatively
few aerosol propellants available today.  If the propellant is not an alkane
such as propane, butane, isobutane, pentane, isopentane, etc., then it is
most likely dimethyl ether (DuPont's Dymel [tm]), methylene chloride, or
fluorocarbon C-318 (octafluorocyclobutane).
