Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Classification based on biodegradation, bioaccumulation and acute aquatic data

Water solubility:     0.034 mg/L (OECD 105)  

Biodegradation:      0% within 28 d (OECD 301F)

LogKow:                  6.3 (OECD 117)

Aquatic acute toxicity

For fish: LC50(96 h) > 1000 mg/L, (UBA-Vorschrift, Letale Wirkung beim Zebrabärbling, Brachydanio Rerio)

For aquatic invertebrates: EC50(48h) > 1000 mg/L (UBA Vorschrift, determination of immobilization of daphnids, Daphnia Magna)

For algae: ErC50(72 h) > 1000 mg/L, (DIN 38 412 part, Desmodesmus subspicatus)

No toxicity in the range of the low water solubility of the test substance has been observed in any of the studies. Although these results do not allow classification, there are nevertheless some grounds for concern. Substances with low water solubility for which no acute toxicity is recorded at levels up to the water solubility [L(E)C50(s) is/are above the water solubility] and which are not rapidly degradable and have an experimentally determined BCF ≥ 500 (or, if absent, a log Kow ≥ 4), indicating a potential to bioaccumulate, should be classified in the Chronic Category 4 ("safety net" classification) unless other scientific evidence exists showing classification to be unnecessary.

Based on the results from the aquatic toxicity studies and since the substance has a low water solubility, is not readily biodegradable and has a log Kow > 4, the substance is classified as Aquatic Chronic 4 (Hazard statement: H413) in accordance with European Regulation (EC) No. 1272/2008.
