Abstract
Aminimides, a new class of surfactants, have been screened for in vitro antimicrobial activity. Greatest activity against gram (+) and yeast organisms is achieved when a chain length of C16 is reached. This generalization is true whether or not the chain length is joined to the imide or amine group. The type of functional group associated with the surfactant is less important than chain length. Gram (‐) organisms do not fit this generalization, since shorter (16) rather than longer chain derivatives are more active. The importance of surfactant chain length to biodegrad‐ability is discussed.
