Abstract
Abstract Additive formulations for use in hydrocarbonaceous materials and particularly in petroleum distillates such as gasoline which provide improved properties thereto will comprise a mixture of the reaction product of an epihalohydrin and a primary amine containing from 14 to 22 carbon atoms and the reaction product of an epihalohydrin and an N-alkyl polyamine containing from 14 to 22 carbon atoms.
