Nanomaterials under Biocidal Products Regulation
Nanomaterials are chemical substances or materials with particle sizes between 1 to 100 nanometres in at least one dimension.
Due to an increased specific surface area by volume, nanomaterials may have different characteristics compared to the same material without nanoscale features. As a result, the physicochemical properties of nanomaterials may differ from those of bulk substances or particles of a larger size.
Many everyday products containing nanomaterials are already on the European market such as batteries, coatings, anti-bacterial clothing and cosmetics. While nanomaterials may offer technical and commercial opportunities, they may also pose risks to our health and the environment. Just like any other substance on the EU market, it is important to ensure that their uses are properly assessed and that any risks are adequately controlled.
ECHA works in close collaboration with Member State competent authorities, the European Commission, NGOs and industry associations as well as international organisations such as the Organisation for Economic Cooperation and Development (OECD), to help implement EU chemicals legislation for nanomaterials.
- 50 % or more of the particles have a size of 1-100 nanometres in at least one dimension
- Particles are in an unbound state or as an aggregate or agglomerate
