Procedure

To a mixture obtained by adding 1,145 parts of stearic acid to 5,000 parts of ethanol and mixing these at 75° C., 200 parts of zinc. hydroxide is gradually added and mixed for 1 hour from the completion of addition. After mixing, the mixture is cooled to 20° C., the product is separated by filtration, ethanol and the reaction residue are removed, and the produced solid taken out is dried at 150° C. for 3 hours in a heating-type vacuum dryer, taken out from the dryer and then allowed to cool to obtain solid zinc stearate.
