Compounds from epoxidised nitriles, process for their production and use as cleaning agents

Aqueous concentrated cooling lubricants are provided in the form of a stable solution ready to use after dilution with water in processes for the mechanical working of aluminum and aluminum alloys, and containing as lubricating and corrosion inhibiting agents a combination of (a) a carboxylic acid R.sub.1 COOH, R.sub.1 having from about seven to about twenty-two carbon atoms, (b) a tertiary alkylalkanolamine having a molecular weight of less than 300 and (c) a water-soluble organic solubilizer having a molecular weight of less than 400, and a hydrocarbon group of at most 6 carbon atoms, the amounts of the carboxylic acid and the alkanolamine being selected to provide a base/acid equivalent ratio of less than 0.9.
