Additional information
The newly measured value from a certified test laboratory with the manufacturers substance according to specification is considered reliable and suitable for use as the key study for this endpoint. It is reasonably consistent with the calculated value from an online database based on an accepted QSAR method and a measured value from an old passed down document.
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.
