Applicant's summary and conclusion
- Conclusions:
- The test item is regarded according to definition of nanoforms: “a
nanoform is a form of a natural or manufactured substance containing
particles, in an unbound state or as an aggregate or as an agglomerate and
where, for 50 % or more of the particles in the number size distribution, one or more
external dimensions is in the size range 1 nm-100 nm, […].”
source: COMMISSION REGULATION(EU) 2018/1881, 03.12.2018, page 8
as "Non Nanomaterial" - Executive summary:
The percentage of particles with an external
dimension below 100 nm is below 50 % for the
analysed dimensions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
