Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Short-term toxicity to fish
In a semi-static acute toxicity test to fish, Danio rerio (zebrafish) were exposed for 96 hours according to OECD 203 (1992). The LC50 was determined to be greater than 0.164 mg/L (measured concentration).
Short-term toxicity to aquatic invertebrates
In a semi-static acute toxicity test to aquatic invertebrates, Daphnia marna (water flea) were exposed for 48 hours according to OECD 202 (2004). The EC50 was determined to be 10.8 µg/L (CI: 6.13 -> 11.0).
Toxicity to algae and cyanobacteria
The 72h-ErC50 was determined to be 106 µg/L, the 72h-ErC10 was determined to be 59.4 µg/L in a study conducted on the fresh algae Pseudokirchneriella subcapitata according to OECD 201 (2011).
Toxicity to microorganisms
According to the ECHA Guidance document R7b, no further test on the toxicity to microorganisms has to be conducted if the toxicity control in a ready biodegradability test shows no inhibitory effects on microorganisms. As the toxicity control in the Manometric Respirometry Test showed no inhibition of the microbial activity at a substance concentration of 100 mg/L, no further test is necessary to evaluate the respiration inhibition of activated sludge. The concentration used in the toxicity control (100 mg/L) can be used as NOEC value (Value determined after availability of all studies).
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.
