| Zusammenfassung: | A lubricating grease of increased water resistance and shear stability comprises a lubricating oil, a thickening agent composed of pyrogenic silica having a particle size of 10-40 millimicrons in an amount sufficient to gell the oil into a grease-like consistency, and 15-30% by weight, based on the weight of the silica, of a water-insoluble polyalkylene glycol having a viscosity at 100 DEG F. of 10-400 cs. In the examples, the polyalkylene glycol is a mixed polyethylene and poly-1,2-propylene glycol. |
