Physical Description
WHITE FINE SOFT POWDER.
Zinc stearate is a white, hydrophobic powder with a slight, characteristic odor. Mp: 130 °C. Density: 1.1 g cm-3. Insoluble in water, ethyl alcohol and diethyl ether. Soluble in acids. Non-toxic. In technical grades, the percentage of zinc may vary according to the intended use. Products with less than the theoretical amount of zinc are more acidic.
