Abstract:
Provided is a water-based lubricant comprising a hyperbranch-type polyglycerol having an absolute molecular weight of from 5,000 to 500,000. The water-based lubricant has a small friction coefficient and is excellent in lubrication performance and defoamability, as compared with conventional water-based lubricants comprising an ethylene/propylene oxide copolymer, and is favorable, for example, for a water-based metal processing agent and a hydraulic pressure fluid.
