Abrégé

A method of improving the emulsification performance of nonionic alkoxylated surfactants, for example when used as fuel additives. The method involves a) providing a composition comprising at least one nonionic alkoxylated surfactant; and b) prior to the addition of said composition to an aircraft fuel, thermally cycling said composition by (i) chilling the composition from a first temperature to a second temperature that causes metal ions and/or associated ions contained therein to precipitate as ionic salts; (ii) filtering the chilled composition to remove the precipitated ionic salts; and (iii) heating the filtered composition to the first temperature.
