New publication in NanoImpact: Intra-laboratory assessment of a method for the detection of TiO2 nanoparticles present in sunscreens based on multi-detector asymmetrical flow field-flow fractionation

Publication

The current EU Cosmetic Products Regulation (EU Regulation (EC) No 1223/2009) requires the labeling of products containing engineered nanoparticles (ENPs). Therefore, reliable and robust analytical methodologies that are fit-for-purpose are a prerequisite for the successful application of the Regulation itself.

Researches from EDGE together with the colleagues from Joint Research Centre in Geel, have carried out an intra-laboratory assessment to establish the effectiveness of a method for the detection of TiO2 engineered nanoparticles present in sunscreen, using quantitative asymmetrical flow field-flow fractionation (AF4).  The study shows that this analytical method, applied after sample preparation method developed within the NanoDefine project, shows good precision, but the trueness can only be taken as a proxy due to the lack of a sunscreen standard containing certified TiO2 ENPs.
