Abstract

A series of new cationic gemini surfactants, bis(alkylammonium) dichlorides having a butenylene or a butynylene spacer, were prepared almost quantitatively by the reaction of a long-chain alkyldimethylamine with a highly reactive allylic or propargylic dichloride, and their surface-active properties were measured. All of them showed good water solubility and quite low critical micelle concentrations, which were more than one order of magnitude lower than those of the corresponding mono(alkylammonium) salts. They also showed quite high foaming ability and foam stability when they have an appropriate hydrophile-lipophile balance. Many of them showed almost the same antimicrobial activities against the eumycetes Aspergillus sp. and Candida albicans as commercial germicides such as benzalkonium chloride and chlorhexidine gluconate.
