Abstract
The formation of toxic compounds such as acetaldehyde and monochlorofluoroethane generated by aerosol antiperspirant mixtures of ACH and 1,1-difluoroethane can be substantially reduced by the addition of one or more additives. Such additives include amino acids, their alkali metal, alkaline earth, ammonium and hydroxy aluminum salts, metal glycinates, hydrotalcite or analogues thereof, and complex aluminum buffering agents. The resultant mixtures are stable for at least two years under ambient storage conditions.
