As part of an effort to find an improved anti-icing additive for jet aircraft fuel the anti-microbial activity of five glycol ether compounds was examined and compared with the currently used additive, 2-methoxyethanol. Cladosporium resinae, Gliomastix sp., Candida sp., and Pseudo-monas aeruginosa were used as assay organisms. Diethylene glycol monomethyl ether, triethylene glycol monomethyl ether, and triethylene glycol monoethyl ether had approximately the same biocidal and biostatic properties as 2-methoxyethanol and appear to be suitable jet-fuel additives as far as the antimicrobial function is concerned. A relatively higher biocidal potency was shown by 2-propoxyethanol and 2-butoxyethanol, possibly because of their greater surface activity however, nonbiological considerations preclude their use as fuel additives.
