Additional information
Analytical measurements of test solutions showed that between 0.7% and 32% of the test substance disappeared from the test solutions, within 2 days of exposure, under the conditions of the test. The quality of the analytical results is validated by analysis of freshly prepared test solutions, which showed recoveries between 89.1% and 98.0%.
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.
