Abstract
Abstract A condensation product of an aldehyde, particularly formaldehyde which may be generated in situ, and an ether-amine of the formula HOCmH2m(OCnH2n)pNH2 where m, n and p are integers, particularly 2-(2''-hydroxyethoxy)ethylamine, is a biocide which is particularly effective against the microbes which attack hydrocarbon fractions, for example jet fuel, in the presence of water, the amount of which water may be very small. The biocide is especially useful as an additive in cutting or soluble oil emulsions to mitigate their degradation by micro-organisms.
