This is a micronized zinc oxide however, it is not a nano particle. It will contribute a whiteness, and a grittiness, to your product at any levels above 7%. Only the nano particle zinc oxide will give you a clear product however, there is a great deal of controversy regarding the use of nano particles in cosmetics. They are still undergoing testing but, are believed to be harmful to human health. Until that question is cleared up and we know that they are safe we will not offer that kind of Zinc Oxide.

Please be aware that it will take 25% zinc oxide to get an approximately SPF (Sun Protection Factor) of 30.
