Procedure: Stearic acid and palmitic acid were mixed at a mass ratio of 50:50 to prepare a mixture, and zinc hydroxide was mixed and melted with the resulting mixture to be reacted therewith, and then dried to produce particles in which zinc stearate and palmitic acid were dissolved in each other (particle diameter: 11 μm to 23 μm). A part of the particles thus produced was dissolved in a hydrochloric acid-methanol solution, and the product was heated to 80° C. to methylate the stearic acid and palmitic acid. The methylation product was analyzed by gas chromatography to determine the zinc stearate content and the palmitic acid content and to express them in terms of the equivalent ratio of zinc stearate to zinc palmitate, and the ratio was found to be 48:52 (mass ratio). was mixed to be reacted dried

Procedure: Stearic acid and palmitic acid were mixed at a mass ratio of 65:35 to prepare a mixture, and zinc hydroxide was mixed and melted with the resulting mixture to be reacted therewith, and then dried to produce particles in which zinc stearate and palmitic acid were dissolved in each other (particle diameter: 11 μm to 23 μm). A part of the particles thus produced was dissolved in a hydrochloric acid-methanol solution, and the product was heated to 80° C. to methylate the stearic acid and palmitic acid. The methylation product was analyzed by gas chromatography to determine the zinc stearate content and the palmitic acid content and to express them in terms of the equivalent ratio of zinc stearate to zinc palmitate, and the ratio was found to be 64:34 (mass ratio). was mixed to be reacted dried

Procedure: In the second precipitation process, a solution of zinc sulfate (0.0163 mol) dissolved in water (100 mL) was added to the mixture of potassium stearate, zinc hydroxide and graphite. This resulted in immediate precipitation of zinc stearate and gave the zinc active mass as a gray precipitate where the zinc stearate, zinc hydroxide and graphite were present as an intimate mixture. This final precipitated mixture was heated to 70° C. and stirred for a further 10 minutes. Upon cessation of stirring, the active mass mixture settled as a uniformly gray material with no stratification consistent with a homogenous mass. After cooling to room temperature, this active mass was filtered and washed with water. The active mass was used immediately without drying.

Procedure: 1,422 parts of stearic acid is added to 10,000 parts of ethanol, and mixed together at 75° C. 507 parts of zinc hydroxide is gradually added to the mixture, and is 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 reaction residue and ethanol. The obtained reaction solid product is dried at 150° C. for 3 hours using a heating vacuum drier. The dried product is taken out from the drier, and is allowed to stand for cooling, as a result of which a solid product of zinc stearate is obtained. After the obtained solid product is milled using a jet mill, the milled product is classified using an ELBOW-JET CLASSIFIER (available from Matsubo Corporation), whereby powdery zinc stearate particles 1 having a volume average particle diameter of 9.6 μm are obtained. The classification cut points when the particles are classified using Elbow-jet classifier are shown in Table 1. The particle size distribution (the ratio of particles having a particle diameter of 25 μm or more, and the ratio of particles having a particle diameter of 40 μm or more) of the obtained zinc stearate particles 1 is shown in Table 1. mixed together at 75° C is mixed for one hour after completion of the addition the reaction product is filtered to remove reaction residue and ethanol The obtained reaction solid product is dried at 150° C. for 3 hours for cooling
