Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

Hazard to aquatic organisms was assessed based on a single key study for each trophic level tested, and consisted of the following:

- (Allen, 2013) Acute toxicity to Oncorhynchus mykiss, conducted in accordance with OECD 203 "Fish Acute Toxicity Test";

- (Allen, 2013) Acute toxicity to Daphnia magna, conducted in accordance with OECD 202 "Daphnia sp., Acute Immobilisation Test";

- (Allen, 2013) Acute toxicity to Pseudokirchneriella subcapitata, conducted in accordance with OECD 201 "Freshwater Algae ane Cyanobacteria, Growth Inhibition Test";

A weight-of-evidence approach was used to define the effect levels presented for toxicity to microorganisms, based on a combination of studies owned by the Registrant, and from the literature. The PNECSTP was therefore based on the following studies:

NOEC = 10 mg/L, activated sludge, OECD 209, Allen (2013)

NOEC = 700 mg/L, P. putida, DIN 38412, part 8 (Pseudomonas Zellvermehrungshemm-Test) , Bringmann & Kuhn (1977)

NOEC = 3,140 mg/L, U. parduczi, Bringmann & Kuhn (1980)

NOEC = 7.7 mg/L, C. paramecium, Bringmann et al., (1980)

Conclusion on classification

In accordance with the criteria of Regulation (EC) No 1272/2008, the substance does not meet the criteria for environmental classification.
