Final Results
The fine fraction of the test item W-1108T has a median particle size of D50 = 12 µm, which was determined by laser diffraction measurement according to OECD Test Guideline 110 (1981) and ISO 13320 (2009).
Applicant's summary and conclusion
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.
