Applicant's summary and conclusion
- Conclusions:
- The particle size distribution of the test item was determined by means of Laser Diffraction Analysis using the medium volume (wet) module (MVM).
The D50 of the test item was determined to be 13.6 µm, the D10 was 6.64 µm and the D90 was 21.6 µm. The MMAD of the test item was calculated to be 15.8 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.
