Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity data for aquatic endpoints are available on the test substance for three trophic levels. The PNEC is based at the highest concentrations tested (100 mg/L), because the LC/EC50 values found were higher than that concentration. An assessment factor (AF) of 1000 is applied to derive the PNECwater. Thus, PNECwater is 0.1 mg/L. No toxicity data for marine water organisms are available and therefore an AF of 10000 is applied to derive PNECsaltwater. Thus, the PNECsaltwater 0.01 mg/L An AF of 100 is applied to derive PNECaqua (intermittent releases), thus PNECaqua (intermittent release) is 1.0 mg/L.

The NOECmicro-organism was 1000 mg/L based on the active sludge respiration inhibition test. An AF of 10 is applied. Thus, the PNECstp is 100 mg/L.

As no data on sediment dwelling organisms and terrestrial organisms is available, EPM is applied to derive PNECsed, PNECmarine-sed and PNECsoil. Based on the available Koc, water solubility, molecular weight and vapour pressure, the PNECsed, PNECmarine-sed and PNECsoil are 0.79, 0.079 and 0.099 mg/kg dw respectively according to guidance on information requirements and chemical safety assessment chapter R.10.: characterisation of dose[concentration]-response for environment.

No PNEC oral is derived as the substance is not expected to bioaccumulate (logPow 1.1)

The VP of the substance is low (< 0.0015 Pa at 20 degree C), thus the very limited hazard for air is expected.

Conclusion on classification

The L(E)C50 on all three trophic levels is >100 mg/L and no classification for acute aquatic toxicity is derived according to CLP (Regulation EC No 1272/2008) or DSD (Directive 67/548/EEC). None of the criteria for classification for aquatic chronic toxicity according to CLP or DSD is met. The substance is not a PBT or vPvB substance and has a high water solubility.

Therefore no classification for aquatic chronic toxicity is necessary.
