Quartz plates for determining sun protection in vitro and testing photostability of commercial sunscreens.

Abstract

Testing plate made of optical quartz has been developed for the purpose of determination of sun protection factor (SPF)(in vitro) by the method of diffusion transmission spectroscopy; the plates were coarsened by sanding and grinding to surface roughness values (Ra) of 18 mum. The plate was coated with a film of sunscreen by an application of 2 mg cm(-2) as… (More)
