A report by the EU’s Joint Research Centre outlines measurement options and factors to take into account when determining if a material fits the definition of a nanomaterial. It may also be helpful for companies registering their nanoforms under the REACH Regulation.

The European Commission has published an updated catalogue of nanomaterials used in cosmetic products on the EU market. It lists nanomaterials used as UV-filters, colourants and preservatives and indicates the cosmetic product categories where they are used together with foreseeable exposure conditions.

A new study has shown that a significant fraction of nanoparticles tested in the toxicity studies of nanoparticles and to develop nanomedicines, may remain in the plastic syringes used to dose the nanoparticles. This has implications on the reliability and reproducibility of the studies and on efforts to reduce animal testing.
