Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Toxicity to fish
The acute toxicity was investigated in fathead minnow. The 96h-LC50 was 2.3 mg/l with a 95 % confidence interval between 2.0 and 3.2 mg/l. A waiver is proposed for long-term toxicity to fish, on exposure grounds.
Toxicity to aquatic invertebrates
The acute and chronic toxicity was investigated in Daphnia magna. The 48h-EC50 corresponds with 0.86 mg/l based on the geometric means of the concentrations measured with the 95% confidence interval defined by the highest level that induced no immobility, 0.67 mg/l and the lowest level that induced 100% immobility, 1.1 mg/l.The 21-day NOEC for reproduction is 0.087 mg/l; 21-day NOEC for body length is 0.087 mg/l.
Toxicity to algae
The toxicity was investigated in Selenastrum capricornutum (new name: Pseudokirchnerella subcapitata).
The EC50 for growth rate reduction (4 day-interval) is above 4.3 mg/l based on the measured concentrations. The NOEC for growth rate reduction (4 day-interval) corresponded with a measured concentration of 1.07 mg/l.Toxicity to micro-organisms
At the concentration(100 mg/l) used in the ready biodegradation test, the substance is not inhibitory to the micro-organisms.
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.
