ABSTRACT:
Compounds of the formula: ##STR1## are provided, in which R.sup.1 and R.sup.2 each independently represent a C.sub.8 -C.sub.24 saturated or unsaturated hydrocarbon chain, which is optionally interrupted by from 1 to 3 heteroatom moieties, such as --O--, --S--, --NH-- and --NR--. The symbol X represents --CH.sub.2 --, --O--, --S--, --NH-- or --NR--. The R group for each of the --NR-- moieties represents an alkyl group having from 1 to 4 carbon atoms. Finally, the subscript n represents the integer 1 or 2, and A.sup.- represents an anion, preferably chloride or citrate.
