Antimicrobial, non-hemolytic cationic polyamines were prepared by treating partially N-acylated polyethylenimines and/or partially oxidized polyethylenimines with a protic acid. The cationic polyamines can have a linear or branched polyethylenimine backbone structure. Preferably, the cationic polyamines comprise pendant urea groups, which can be introduced via a cyclic carbonate comprising a pendant urea group. The cationic polyamines can be active against a tuberculosis mycobacterium at low concentration. The cationic polyamines are also effective against Gram-negative Escherichia coli and Pseudomonas aeruginosa, Gram-positive Staphylococcus aureus, and fungus Candida albicans in solution and in the form of a film.
