Abstract
The present invention relates to novel bishydrazide quaternary salts, useful as surfactants and antibacterial agents. The novel bishydrazide quaternary salts correspond to the general formula ##STR1## wherein R=(C.sub.9 -C.sub.19)alkyl, (C.sub.13 -C.sub.19)alkenyl, unsubstituted and substituted aryl; X.sup.- is an anion, and R.sub.1.sup.+ is a ##STR2## group pa The present invention also relates to processes of preparing the compounds of formula (I) and antibacterial compositions containing them.
