Any other information on results incl. tables
The test item was not stable at ambient atmosphere (the test item was stored under nitrogen). For information, the test item, left for about one hour at ambient temperature changed: The clear yellow powder turned to a dark yellow powder that softened with time. In those conditions, the dry or wet sieving was not applicable to this test item.
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.
