Nanomaterials under Biocidal Products Regulation
Nanomaterials are chemical substances or materials that are manufactured and used on a very small scale. Their structures range from approximately 1 to 100 nm in at least one dimension.
Nanomaterials have unique and more pronounced characteristics compared to the same material without nanoscale features. Therefore, the physico-chemical properties of nanomaterials may differ from those of the bulk substance or particles of a larger size.
Nanotechnology is rapidly expanding. A large number of products containing nanomaterials are already on the European market (e.g. batteries, coatings, anti-bacterial clothing, cosmetics, food products). Nanomaterials offer technical and commercial opportunities, but may pose risks to the environment and raise health and safety concerns for humans and animals.
- 50% or more of the particles have a size of 1-100 nm in at least one dimension
- Particles are in an unbound state or as an aggregate or agglomerate
