Nano-sized ingredients have their established position in cosmetics. Since 2009, the Cosmetics Regulation is requesting a separate assessment of materials which are classified nano. In addition, the definition of nanomaterial leaves a wide room for interpretation.

One of the most challenging issues is how to distinguish between the effects caused by the chemical itself and those caused by its physical size.

The challenges and uncertainties being faced during the long registration road of nano UV-filters are described and exemplified by two organic UV-filters.
