SYNTHESIS AND ANTIMICROBIAL PROPERTIES OF NEW MANDELATE IONIC LIQUIDS.

Novel mandelate ionic liquids with quartenary ammonium cations were synthesized and characterized. The compounds exhibit antimicrobial activity and the most potent one is of similar efficacy against Gram+ bacteria as its counterpart chloride. On the other hand, the mandelates are much less active against Gram-bacteria and fungi.

Long-alkyl-chain quaternary ammonium lactate based ionic liquids.

A new group of quaternary ammonium lactate based ionic liquids have been prepared and characterized. Didecyldimethylammonium (DDA) and benzalkonium (BA) D,L- and L-lactates are air-stable, hydrophilic, surface-active salts. They are very effective antibacterial and antifungal agents, especially the DDA lactates, against Streptococcus mutants and Candida albicans.
