Procedure

A molten stearic acid (22.2 grams, Industrene 7018) was added gradually to a stirred slurry mixture of zinc oxide (4 grams), citric acid (0.1 gram), and water (70 grams) at 60° C. The mixture was stirred at 60-70° C. for 30 minutes to afford a product mixture with zinc stearate floating, which was filtered and dried to give a quantitative yield of zinc stearate as shown by its infrared spectrum.
