Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity to fish:

LC50 (Cyprinus carpio, 96 h) = 748 mg/l

Short-term toxicity to aquatic invertebrates:

EC50 (Daphnia magna, 24 h) = 216 mg/l

QSAR prediction: not classified for aquatic toxicity to Daphnia

Toxicity to aquatic plants other than algae:

ErC50 (Lemna minor, 7d) > 100 mg/l

Toxicity to microorganisms:

IC 50 (3 h)> 100 mg/l

Additional information

Adequate chronic toxicity data are not available for the substance; therefore the aquatic toxicity assessment and classification are based mainly on the short-term toxicity data available on the target substance.

Despite the substance has a log Kow very lower than 4 (indicating a low potential for bioaccumulation), it is not rapidly (bio)degradable.

According to the CLP Regulation (EC 1272/2008), acute aquatic toxicity is normally determined using a fish 96-hour LC50, a crustacean species 48-hour EC50 and/or an algal species 72- or 96-hour EC50.

The acute toxicity to fish, invertebrates and aquatic plants were conducted to:

-Cyprinus carpio according to the OECD Guideline 203 (1984);

-Daphnia magna according to the OECD Guideline 202 (1984);

-Lemna minor, according to the OECD Guideline 221 (2006).

According to the CLP Regulation (EC 12720/2008), the results obtained for the substance did not respect the classification criteria for the hazardous categories to the aquatic environment. Thus, the substance is not classified.
