Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

The substance is readily biodegradable, has a log Kow of 3.5 and a water solubility of 310 mg/L

There are acute ecotoxicity data available for three trophic levels where the 72h ErC50 of 25 µg/L as observed for algae is the lowest value

There is one long term ecotoxicity result available i.e. the 72h ErC10 of 3.3 µg/L which was observed for algae.

Based on this data

The substance should be classified (CLP) as: Acute 1 with M-factor 10 because 0.01 < L(E)C50 0.1 mg/L

The substance should be classified (CLP) as: Chronic 1 with M-factor 1 because 0.001 < NOEC ≤ 0.01 mg/L
