Physicochemical Properties and Antimicrobial Performance of Benzyldimethylalkylammonium Bis(2-ethylhexyl) Phosphate

Abstract

Benzyldimethylalkylammonium salts with bis(2-ethylhexyl) phosphate maintain their liquid state at room temperature. These are immiscible but can be dispersed stably in water. The benzyldimethyltetradecylammonium salt emulsion exhibited the highest antimicrobial activity among them and some advantages as an additive for aqueous media compared with conventional cationic-surfactant-type antimicrobial agents.
