In accordance with the present invention there is provided an additive for cold rolling lubricants which improves the lubricity, as well as the cooling properties, of the lubricant. According to the present invention, a polar liquid with a boiling point between 25° C. and 500° C. may function as an additive for cold rolling lubricants. The additive is added to a typical cold rolling lubricant such as an oil comprising of 5-10 percent fatty alcohol and 1-2 percent fatty ester in a hydrocarbon oil. The additive is added to the rolling lubricant in the proportions of about 0.1 to 10 percent, preferably about 1 to 4 percent and more preferably about 1 to about 3 percent. The additive of the present invention lowers friction at higher rolling speeds and metal reductions and exhibits an improved cooling ability. Optionally, a small amount of water may be added to the additive/lubricant composition to further increase the composition's cooling ability. In one aspect of the present invention the additive/lubricant may also contain less than 1 percent corrosion inhibitor.
