Procedure

A molten stearic acid (22 grams, Industrene 7018) was added gradually to a stirred slurry comprising zinc oxide (3.6 grams), Methocel F50 (0.2 gram), Tergitol 15-S-7 (0.2 gram), and water (70 grams) at 55° C. The mixture was stirred at 65-70° C. for 1 hour to produce a yield of zinc stearate of about 50% by its infrared spectrum.
