Reaction Steps

A molten stearic acid (202 grams of Hystrene 4516) was added gradually to a stirred slurry of zinc oxide (32 grams), citric acid (0.5 gram), Methocel F50 (3 grams), and water (560 grams) at 65° C. The mixture was stirred at 65-75° C. for 1 hour to afford after filtering and drying a 100% yield of zinc stearate as indicated by its infrared spectrum. The resulting product was a white powder having free fatty acid content of 0.22% by weight.
