Applicant's summary and conclusion
- Conclusions:
- The test item consisted of transparent particles which appeared irregularly shaped.
The median particle size L50 of the test item deduced from the particle size distributions is 11.3 µm.
The particle size L10 of the test item deduced from the particle size distributions is 1.9 µm.
The particle size L90 of the test item deduced from the particle size distributions is 80.1 µm.
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.
