Lubricant compositions are provided which contain: oleaginous media, and an antiwear and water tolerance improving amount of a product formed by reacting (a) a compound having the formula: where R' is a substantially unbranched paraffinic alkyl group containing from about 10 to about 36 carbon atoms, and R is a hydrocarbyl group containing from 1 to about 4 carbon atoms with at least one hydrogen atom present on the carbon atom which is bonded to the oxygen; (b) a substituted imidazoline of the formula: where one of the R2 and R3 substituents must be a substantially unbranched paraffinic or olefinic hydrocarbyl group containing from 12 to 35 carbon atoms; and the other R2 or R3 substituent is selected from the group consisting of: paraffinic alkyl. containing from 1 to 35 carbon atoms, alkenyl containing from 1 to 35 carbon atoms, and hydroxy-, alkoxy-, alkoxymethoxy-, and oxo-substituted alkyl and alkenyl containing from 1 to about 20 carbon atoms, and (c) water. Particularly contemplated are compositions in the form of lubricating oils and greases. |
