Zinc Oxide French Process 50 Pound Bag
Our zinc oxide is prepared using the indirect process aka "French Process".
The zinc is vaporized. In the vaporized state the zinc is able to pick up an oxygen atom from the atmosphere and become ZnO.
Our Zinc Oxide product is a brilliant white powder manufactured by the French (Indirect) Process.
Grade 104 is our popular medium particle size zinc oxide offering high assay and very low impurities.
Grade 104 is approved for pharmaceutical drug use as an excipient, is USFDA approved as GRAS (Generally Recognized As Safe) at 21cfrl82.8991 and is authorized by the USFDA for use wherever GRAS is approved including food contact in rubber, plastics, and coatings. Grade 104 also meets the requirements of ASTM specification D79, 2002/95/EC Restriction of Hazardous Substances Directive (RoHS) for heavy metals and Waste Electrical and Electronic Directive (WEEE), and other regulations where high quality zinc oxide is required.
