text: However, where conditions require both'a high degree of cooling plus a high degree of hydrodynamic or oil film lubricity characteristics, the water soluble lubricants have not been suitable because they have been unable to deposit a film containing sufficient lubricity for proper function under hydrodynamicconditions.
text: This invention now provides an improved water soluble lubricant which deposits a film on surfaces to be lubricated where the deposited film has greatly improved lubrication and anti-frictional qualities.
