Synthesis and Surfactant Studies of Dialkyl Dimethyl Quaternary Ammonium Bromide Formulations

Quaternary ammonium salts (otherwise known as quats) are commonly used active ingredients in biocide formulations used in the anti-microbial industry. Although quats have been established to be effective biocides, there are few studies investigating the maximization of biocidal efficacy in multiple component formulations using various carbon chain lengths. Reported here is the synthesis based on the Sn2 reaction of tertiary amines with alkyl bromide. Surfactant studies of the single and dual component systems were conducted, and the evaluation is explored.
