Abstract

Reaction products of .epsilon.-caprolactam with vicinal hydroxyalkylamines and possible adducts thereof with epoxyalkanes having the overall formula: ##STR1## wherein R.sub.1 and R.sub.2 are members selected from the group consisting of hydrogen and alkyl having 1 to 16 carbon atoms with the proviso that the sum of the carbon atoms in R.sub.1 and R.sub.2 is from 6 to 30 when R.sub.1 and R.sub.2 are alkyl and from 6 to 16 when R.sub.1 or R.sub.2 is hydrogen, R.sub.3 is a member selected from the group consisting of hydrogen, alkyl having 1 to 5 carbon atoms and ##STR2## where m is an integer from 2 to 10, and R.sub.4 and R.sub.5 are members selected from the group consisting of hydrogen and alkyl having 1 to 3 carbon atoms, EPA is an epoxide selected from the group consisting of ethylene oxide, propylene oxide and glycide, x is a number representing mols of from 1 to 5 and y is a number representing mols of from 0 to 5; and the organic and inorganic acid salts thereof; the reaction products are useful as antimicrobials in the treatment of aqueous media and in detergents together with other surface-active compounds.
