Results and discussion
Densityopen allclose all
Any other information on results incl. tables
Although the actual measurement temperature for the Purified Active was 20.7 °C and not 20 °C, it is considered that this would have made no significant difference to the reported result. The change in density with temperature for most materials is negligible over a few degrees range, eg the change in density of water is -0.0002/°C, and this is considered a large magnitude change. Any inaccuracy may be expected to be within the overall experimental error of the procedure. Therefore, although the result should strictly be reported as a D21/4 value, it is considered not significantly different from a true D20/4 value.
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.
