Broad spectrum antibacterial compositions containing tris (hydroxymethyl)-aminomethane and diphenyl and loweralkyl substituted diphenyl polyamines

摘要

A composition comprising tris-(hydroxymethyl)aminomethane and diphenyl and loweralkyl substituted diphenyl polyamines, their acid addition salts, and mixtures thereof are useful as antibacterial agents. The composition is particularly useful because of the synergistic improvement obtained against strains of the genus Pseudomonas, as well as other genera.
