Abstract
Abstract Lubricating compositions which contain significant amounts of chlorinated oils (e.g. paraffin oils which have been chlorinated to more than 40 percent chlorine) are improved for use as metalworking lubricants by the inclusion therein of additive amounts (e.g. 5 weight percent) of one or more ethoxylated fatty amines (e.g. a tertiary amine having one C12-C18 fatty alkyl group or radical and 2 polyoxyethylene groups or radicals attached to the amine nitrogen atom). The improved lubricating compositions have a reduced tendency to corrode the metal being worked and are self-emulsifying, thereby permitting the improved lubricating compositions to be removed from the worked metal by aqueous or solvent methods (e.g. water washing).
