-
The bactericidal activities of two series of quaternary Gemini surfactants have been examined by the suspension quantitative germicidal tests against Escherchia, Staphylococcus aureus and Candida alibicans respectively, the dodecyltrimethylammonium bromide(C12TABr) was used for comparison. All of the quaternary Gemini surfactants showed superior bactericidal activities to C12TABr due to higher densities in both headgroup charge and alkyl chains.
