Comments:
LC100 at 96 hours (mg/l) >limit of solubility
The toxicity results are based on the centrifuged mean
measured exposure concentrations of the test substance
The post-centrifugation mean measured concentration of the
test substance was 0.41 mg/l (4% of the nominal exposure
concentration)
Limit test performed at maximum achievable concentration.
Solutions stirred for 24 hours prior to testing to achieve
maximum dissolution. No toxicity observed.
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.
