Zinc Oxide

Also known as zinc white and Chinese white. A white or yellowish powder that occurs in nature as the mineral zincite. Used in sunscreen as a physical blocker that absorbs UV rays, zinc oxide is noticeable by the white residue it leaves on skin. Nanotechnology is now being employed to reduce the particle size, resulting in a clear product. While traditional zinc oxide is considered safe and non-toxic, there is limited information of the safety profile of micronised zinc oxide. Also found in formulations to protect skin from dehydration, wind and diaper rash. See Oxide Pigments.
