Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

The substance is a liquid at ambient temperature. It is poorly soluble in water (< 0.1 mg/L), has a low volatility (vapour pressure < 0.0001 Pa at 20 °C) and has a high affinity for soil / sediment (log Koc soil > 5.6).

It is not readily biodegradable and its hydrolisys is very slow QSAR results using HYDROWIN v2.00 resulted in DT50 values > 1 yr at pH 7).

Biodegradation in aquatic and terrestrial environment is expected to be low.

Evaporation into air and the transport through the atmospheric compartment is not expected due to the low vapour pressure.

Considering the low water solubility and the potential for adsorption to organic soil and sediment particles, the main compartment for environmental distribution are expected to be soil and sediment.

When entering a standard STP, the substance will be extensively removed in the primary settling tank and fat trap and thus, only limited amounts will get in contact with activated sludge organisms. Nevertheless, once this contact takes place, the substances ise expected to be removed from the water column to a significant degree by adsorption to sewage sludge (Guidance on information requirements and chemical safety assessment, Chapter R.7a, (ECHA, 2017). Thus, discharged concentrations of this substance (if at all) into the aqueous/sediment and soil compartment are likely to be low.

Moreover, bioaccumulation of the target substance is assumed to be low based on the molecular weight and physico/chemical properties such as low water solubility and high potential for adsorption a reduced availability in water is expected.

 As such, any environmental release will result in virtually all of the substance compartmentalising into the sediment/soil compartment, with little release directly to atmosphere.
