The invention provides a process for the preparation of a lithium soap thickened grease which consists of heating a mixture of an oil and a lithium base, and optionally also a calcium base, to at least 100 DEG C., then adding a C10-24 saturated or unsaturated fatty acid, and heating the resulting mixture at a temperature in the range 110 DEG C. to 200 DEG C. until a thickened grease is obtained. |
