- Description:
- The information reported reflects the state of the collected information from most of the co-registrants. However, all the data for structure are not yet identified.
- Range of specific surface area:
- >= 10 - <= 400 m²/g
- Surface treatment applied:
- no
- Does the set contain both treated and non-surface treated nanoforms?:
- no
- PBT status:
- PBT assessment does not apply
- Justification:
PBT assessment does not apply because the substance is inorganic.
