PURPOSE: To produce a low-syneresis grease which shows a low-level degree of syneresis even when used or stored for a long time, has a high degree of freedom of base oil selection and is easily obtainable by a simple process.
CONSTITUTION: A grease comprising component (A) comprising at least one base oil selected from among an organic synthetic lubricating oil, a silicone lubricating oil and a mineral oil, component (B) comprising a soap-base thickener and component (C) comprising a metal behenate as a syneresis inhibitor, wherein the ratio of component B to component C is 100:1 to 100:230 by weight. This grease is prepared by mixing component A with component (B1) comprising a fatty acid or its ester, component (C1) comprising behenic acid or its ester and component D comprising a compound containing a metal component which saponifies components (B1) and (C1) to thereby saponify components B1 and C1 with component D.
