Abstract

Fuel-water emulsions in which an alkoxylated, preferably an ethoxylated, polyisobutene is used as an emulsifier are described. Stable emulsions, in particular of diesel-water mixtures, which have advantageous properties when used as fuel in internal combustion engines can be prepared in this manner.
