ABSTRACT:
Compositions which include mixtures of a calcium hydroxide overbased oil-soluble calcium sulfonate, hexylene glycol and a surfactant consisting of an ethoxylated aliphatic amine, particularly, diethoxylated cocoamine or diethoxylated soyamine, are useful as rust inhibiting additives for oils and the like. By incorporating these compositions in petroleum based oils such as petroleum based oils of lubricating oil quality which come into contact with metal surfaces under conditions such that the metal surfaces tend to rust or otherwise be subject to deterioration it is possible to inhibit rust formation on such metal surfaces.
