Beschreibung
Zusammenfassung:	The grease composition comprises at least one a base oil selected from a mineral oil and a synthetic hydrocarbon oil, and a thickener prepared by mixing a lithium soap containing no hydroxyl group in its chemical structural formula and a lithium soap containing a hydroxyl group in its chemical structural formula. The grease composition of the present invention shows a decrease on the amount of its scattering at an ambient temperature as well as a high temperature, and improves the sound quality and friction property of bearings of electronic computers. Mixtures of Li stearate and 12-hydroxy-stearate are disclosed.
