Zinc oxide particles Synthesis properties and applicationsIngredient Glossary Zinc Oxide Organic Makeup

Zinc oxide produced by the French process can have high purity gt 99 if high purity zinc is used a feedstock However the product may contain traces of zinc metal the amount of which is inversely proportional to particle size and which may render it unsuitable for some applications 31 35 36 A special process allows us to keep larger zinc oxide particles from clumping whereas the smaller nano and near nano particle zinc in most other sunscreens clump together to form larger aggregate particl As a result our large particle zinc oxide is able to go onto the skin clear
