Electron microscopic investigation and elemental analysis of titanium dioxide in sun lotion

ConclusionA novel defatting method for sample preparation of titanium dioxide nanoparticles used in sun cosmetics was developed. This method was applied to six different sun lotions with SPF between 30 and 50+. TiO2 particles were found in only five sunscreens. The sizes of the primary particles were below 100 nm and according to the EU Cosmetic Regulation have to be listed on the package with the term “nano”.This article is protected by copyright.
