Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The lowest acute effect concentration for the test substance is the 96-hour EC50 of 154.9 for algae. Since a full base set of acute aquatic test data is available, an assessment factor of 1000 is appropriate for calculation of a PNEC aqua-freshwater. The Predicted No Effect Concentration for surface water is PNECwater= 0.155 mg/L.

The PNEC aqua-marine water was derived from the freshwater base set of test using an AF of 10,000. The Predicted No Effect Concentration for marine water is  PNECaqua - marine water= 0.016 mg/L.

The PNECs for freshwater sediment, marine sediment, and soil were derived from the appropriate PNEC values, the Koc value for the dominant non-aqueous-phase constituent in the test substance (Koc = 7.8 mL/g) and appropriate equilibrium partitioning equations. 

The PNECSTPwas derived from the Pseudomonas study endpoint of > 1600 mg/L in conjunction with an AF of 10.

Based on a log Kow < 3.0, limited potential for exposure and bioaccumulation and lack of classification for toxicological effects in mammals, it was not considered useful to derive a PNECoral.

Conclusion on classification

Conclusive but insufficient for classification
