Wiechers, S. published the artcileTitanium dioxide particle size vs. sun protection performance, Application of 3-((2-Ethylhexyl)oxy)propane-1,2-diol, the publication is Cosmetics & Toiletries (2013), 128(5), 332, 334, 336, 338-339, database is CAplus.
The article compares the performance of titanium dioxide as a UV filter in cosmetic formulations as a function of its primary particle size. It was found that with increasing primary particle size, even below 100 nm, the effectiveness of the inorganic (mineral) UV filter was clearly reduced.
