Concentrates of N-substituted morpholines of the formula O(CH2CH2)2NR'YR'', wherein R' is a divalent organic radical of at least one to about 30 carbon atoms, Y <IMAGE> or -NH3-, R3 is a hydrogen atom or a hydrocarbyl radical of at least one carbon atom and R'' is a monovalent hydrocarbon radical of at least 15 carbon atoms, are useful as additives for hydrocarbyl products. Particularly preferred embodiments of the invention include concentrates wherein Y is <IMAGE> R' is 1,3-propylene and R'' is a hydrocarbyl group of at least about forty carbon atoms. These concentrates have utility as, for example, additives for lubricant compositions.
