N,N'-Bridged-bis[(O and/or N-substituted)-2-alkyl-2-hydroxyethylamines] of the formula ##STR1## are prepared by condensing an epoxide of the formula ##STR2## and a diamine of the formula R'NH-X-NHR'. The products and dicarbanilates, acid-addition salts, N,N'-dioxides and N,N'-diammonium quaternary salts derived therefrom have antibacterial activity in vitro and are useful as antibacterial agents.
