ABSTRACT OF THE DISCLOSURE High molecular weight polyglycerol derivatives, useful as thickening agents for water-based lubricants, are prepared by oxyalkylating a polyglycerol with ethylene oxide or a mixture of ethylene oxide and propylene oxide. The polyglycerol derivatives are characterized as having an average of more than five glycerol units, and in having more than 95% and preferably more than 99% alkylene oxide units. These compounds exhibit excellent shear strength and provide an improved hydrolube when lncorporated therein.
