Water hardness = Standard test medium used
The analytical results indicate that the test concentration
of BEM 4522 used in this study was at, or close to, the
limit of solubility. Measured concentrations in the
centrifuged samples were 0.067 and <0.036 mg/l at 0 and 72
hours.
Mean measured concentrations in non-centrifuged samples were
9.3mg/l at 0h and 2.7mg/l at 72h.
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.
