Product 1

HCID 23668746Lithium hydroxystearate

Procedure

12-hydroxystearic acid was reacted with lithium hydroxide in a mole ratio of 1:1 under heating in a proper amount of the same refined mineral oil as one used in the preparation of urea-urethane base grease A to obtain lithium 12-hydroxystearate, and then the obtained lithium 12-hydroxystearate was dispersed in such an amount of the refined mineral oil as to give a lithium 12-hydroxystearate content of 8% by mass based on the total amount of the lithium soap base grease C.
