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).
