Quanta99 Posted May 23, 2007 Posted May 23, 2007 Would anyone be able to tell me how transparent sunscreen is manufactured? I know how it works and why it is better than normal conventional sunscreen (ie. as nanomodified sunscreen contains only 2% w/w ZnO there is a greater surface area to volume ratio and hence the ZnO acts as a better UV filter). But exactly HOW is it manufactured?
