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.
- quaternary ammonium Gemini surfactant,
- germicidal activity,
- Escherchia,
- Staphylococcus aureus,
- Candida alibicans
