Zinc oxide nanoparticle. Zinc oxide nanoparticles are nanoparticles of zinc oxide (ZnO) that have diameters less than 100 nanometers. They have a large surface area relative to their size and high catalytic activity. The exact physical and chemical properties of zinc oxide nanoparticles depend on the different ways they are synthesized.

Introduction Zinc oxide nanoparticles (ZnO NPs) are used in a wide range of industrial and personal care products; 1–3 the unique antibacterial and anticancer properties of ZnO NPs have expanded their applications into the biomedical field. 4,5 Accordingly, concerns have been raised over the increasing production and subsequent release of ZnO NPs into aquatic environments, which poses a

Zinc Oxide formulations need to be at a pH>7 to avoid solubilization of the Zinc Oxide in the water phase; Need to use coated Titanium Dioxide and Zinc Oxide to reduce photo/chemical reactivity and improve skin feel; Nano PR issues in Europe: Particles in formulations < 100nm are considered to be nano and need to be labeled as such.
Maybe the non-nano demand isn’t as large as I thought, I’m personally fine with nano scale zinc oxide (it’s even FDA approved for used in food), but wondered if there were any off the shelf non-nano non-whitening options on the market, e.g. Grant has a UV-Cut ZNO 61 with a primary particle size of 255 nm that could be best of both worlds Until recently, zinc oxide sunscreen formulations appeared as a thick, white paste on the skin. However, new nanotechnology has revolutionized the opaque appearance of zinc oxide by refining the zinc particles to make them smaller. But can these tiny particles be harmful to our body? zzjqs.
