Applicant's summary and conclusion
- Conclusions:
- No particles smaller than 10 micrometer were detected, therefore, it can be concluded that the inhalative toxicity doesn't have to be tested.
- Executive summary:
No particles smaller than 10 micrometer were detected, therefore, it can be concluded that the inhalative toxicity doesn't have to be tested.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
