Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Environmental fate and pathways

Biodegradation

Not readily biodegradable (5.99% in 28 d, OECD 301 D)

Bioaccumulation

log Kow = 4.11 (OECD 107, EU method A.8)

 

Aquatic short-term toxicity

Aquatic invertebrates

EC50 (48 h) = 4.7 mg/L (nominal, OECD 202, D. magna)

Aquatic algae

ErC50 (72 h) = 4.42 mg/L (nominal, OECD 201, P. subcapitata)

Fish

LC50 (96 h) = 2.39 (nominal, OECD 203, O. Latipes)

Aquatic long-term toxicity

Aquatic algae

ErC10 (72 h) = 1.53 mg/L (nominal, OECD 201, P. subcapitata)

 

Conclusion on CLP

Short-term effect values are available for all three trophic levels and one long-term effect value is available for aquatic algae. All EC/LC50 values for acute toxicity are in the same order of magnitude and > 1 mg/L. Therefore, the substance is not classified as acutely hazardous to the environment. However, the EC/LC50 values are > 1 to ≤ 10 mg/L and the substance is not readily biodegradable according to OECD criteria and has a log Kow of 4.11. Therefore, the substance is classified and labelled as Category Chronic 2 for long-term environmental hazards, according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments.
