Abstract
Abstract This invention relates to water active metalworking lubricant compositions, particularly for the cold rolling of aluminum and other sensitive non-ferrous metals and alloys. Water emulsions or solutions of the lubricant composition provide good lubricity and anti-wear properties and furthermore, prevent water staining of aluminum. The water active lubricant composition contains (a) an alkanolamine salt of a C 36 dimer or C 54 trimer acid, (b) an aliphatic monoalcohol or monocarboxylic acid and (c) an alkyl ester of a fatty acid.
