Metalworking lubricants comprise an ester formed by the reaction of an alkenyl succinic anhydride or acid in which the alkenyl group is derived from a C16-18 olefine or dimer thereof or C12-20 monocarboxylic acid or dimer thereof with a hydroxyamine. The lubricants may be emulsified, with water, and in this form are particularly suitable for can forming operations. |
