Procedure

A molten stearic acid (29.7 grams, Industrene 7018) was added gradually to a stirred slurry of zinc oxide (4.86 grams), phosphoric acid (0.13 gram, 85% solution in water), Tergitol 15-S-7 (0.8 gram), and water (65 grams) at 65° C. The mixture was stirred at 55-73° C. for one hour to give a quantitative yield of zinc stearate as shown by the infrared spectrum of the final product.
