ABSTRACT:
Antimicrobial and algicidal compositions active against bacteria, fungi and algae containing from 0.1% to 10% by weight of reaction products of .epsilon.-caprolactam with N-alkylalkylene diamines of the formula ##EQU1## wherein R denotes a straight- or branch-chained, saturated or unsaturated aliphatic hydrocarbon substituent with 10 to 18 carbon atoms, R.sub.1 denotes hydrogen or an aliphatic hydrocarbon substituent with 1 to 4 carbon atoms, where n is an integer of from 2 to 6, preferably 3, and where the molar ratio of the reaction partners N-alkylalkylene diamine: .epsilon.-caprolactam is 1:1 to 1:10, and the reaction is carried out for 3 to 20 hours in the liquid phase at temperatures above 180.degree.C, preferably at about 250.degree.C. These reaction products are useful in compositions to prevent the growth of microorganisms, such as bacteria, fungi and algae.
