Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Key Value has been selected from Seeland publication representing a clearly more sensitive species of daphnids (D. galeata, non-standard test organism) in freshwater.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Dose descriptor:
- EC50
- Effect concentration:
- 15.8 mg/L
Additional information
Four freshwater studies with invertebrates (3 studies with D. magna, 1 study with D. galeata) are available. While the three studies with D. magna show an EC50 (48h) of about 100 mg/L, an EC50 (48h) of 15.8 mg/L with D. galeata has been observed. The difference in the sensitivity of the species is mostly likely due to the smaller size of D. galeata.
Although the publication shows some deficiencies in reporting, the publication is selected for the chemical safety assessment as it also was performed according to the OECD 202 test guideline and the parallel test with D. magna showed an analogue effect value like the studies from the GLP laboratories indicating a comparable quality standard of the laboratories.
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.
