Key value for chemical safety assessment
Additional information
One key study (Klimisch score=1) was identified, in which FEXO-07 were tested for toxicity to aquatic algae using a method according to OECD 201 and EU Method C.3.
The substance was tested on Pseudokirchnerella subcapitata for a test period of 72 hours.
Besides the five concentrations, a negative control was also prepared to check the acceptability of the algal inoculum. The test item concentration has shown a very large decrease compared to nominal values already short after being prepared. Therefore, the biological results are not referred to the nominal concentrations but to the median of the measured concentrations.
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.
