Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Six aquatic toxicity studies are available:
Test |
Species |
Result |
|
|
|
short-term toxicity to fish |
Oryzias latipes |
LC50(96h) = 4.5 mg/L (nominal) |
short-term toxicity to aquatic invertebrates |
Daphnia magna |
waived, poor water solubility, chronic data available |
long-term toxicity to aquatic invertebrates |
Daphnia magna |
NOEC(21d) = 6.5 µg/L |
toxicity to aquatic algae and cyanobacteria |
Pseudokirchneriella subcapitata |
EC50(72h) = 6.17 mg/L (nominal) LOEC (72h) = 3.76 mg/L (nominal) |
toxicity to aquatic algae and cyanobacteria (2012) |
Pseudokirchneriella subcapitata |
EC50(72h) >236 µg/l (solubility limit) |
toxicity to microorganisms |
|
no effect at 1000 mg/L |
The 96 hr LC50 for fish, the ErC50 for algal growth inhibition were all greater than the solubility of the test material. No toxicity to microorganisms was observed at a loading dose of 1000 mg/l, also above the solubility limit. The 21- day NOEC was greater than 6.5 μg/L, the maximum concentration it was possible to maintain over the course of the study (nominal 20μg/L); no effects were observed in this study. It is therefore concluded that no effects have been observed in either short or long term tests for any aquatic species tested
