Abstract
A new family of surfactants, aminimides, has been screened forin vitro antimicrobial activity. These compounds are active against both bacteria and yeast, activity being a function of chain length. Maximum activity for acetimide and acrylimide amine derivatives was extablished with chain lengths of C14–C16. Homologous compounds with lower or higher chain lengths were less active. While showing low antimicrobial activity against gram negative bacteria, mixtures containing C12 and C16 gave good activity against gram negative strains without losing gram positive activity. Aminimides gave low acute LD50’s (200–400 mg/kg) when tested in mice by intraperitoneal injection.
