Reaction Steps
A molten stearic acid (29.5 grams, Hystrene 7018) was added gradually to a stirred mixture of zinc oxide (4.9 grams), citric acid (0.06 gram), Tergitol 15-S-7 (0.35 gram) and water (66 grams) at 65° C. The reaction mixture was stirred at 60-70° C. for one hour, cooled to 25° C., filtered and dried to give 32.6 grams (99.1% yield) of zinc stearate white powder that showed 0.08% water, 13.6% ash, 0.49% by weight of free fatty acid, and a melting point of 126° C.
