There are some websites that list producs with nanotechnology, for example:
- The Nanodatabase (Englisch): http://nanodb.dk/en/search-database/
- The Project of Emerging Nanotechnologies (in English): https://nanotechproject.tech/cpi/
For cosmetic products labelling of “nano” ingredients is mandatory since July 2013 and for food and food contact materials since Dec 2014.
