About Zinc Stearate, Lab Grade

Zinc Stearate, also known as Stearic Acid Zinc Salt, Octadecanoic Acid, Zinc Dioctadecanoate, and Zinc Distearate, has the chemical formula C36H70O4Zn or [CH3(CH2)16COO]2Zn. It appears as a fine, white, soft powder with a slight, characteristic odor. It is insoluble in water, ethanol, and ether; soluble in benzene, acids, and common solvents when hot. It can be produced in a variety of different ways. Commonly, the Zinc Sulfate solution is reacted with the Sodium Stearate solution to produce Zinc Stearate, which is then washed and dried.

Lab grade chemicals possess reasonable purity but do not comply with any official standard for quality or purity like the ACS Grade, the USP Grade, or the FCC Grade. The Lab Grade is also known as Laboratory Reagent (LR) and Chemically Pure (CP). Lab Alley’s Zinc Stearate, Lab Grade is recommended for educational institutes, research labs, and commercial applications.
