Методика

1,422 parts of stearic acid is added to 10,000 parts of ethanol, and mixed together at 75° C. 298 parts of magnesium hydroxide is gradually added to the mixture, and mixed for one hour after completion of the addition. The resultant mixture is cooled to 20° C., and the reaction product is filtered to remove ethanol and reaction residue. The obtained reaction solid product is dried at 150° C. for 3 hours using a heating vacuum drier. The product is taken out from the drier, and is allowed to stand for cooling, as a result of which a solid product of magnesium stearate is obtained. The obtained solid product is milled and classified in a similar manner to the production of zinc stearate particles 1, and further classified in a similar manner to the production of zinc stearate particles 6, as a result of which magnesium stearate particles 1 are obtained. The particle size distribution of the obtained magnesium stearate particles 1 is shown in Table 1.
