Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 adsorption potential of the substance was calculated from the log Kow using the equation from EUSES (non-hydrophobics QSAR, because the log Kow < 3). The calculated Koc value is 129 L/kg (log Koc = 2.1). Based on this value, the substance has low potential for adsorption to solid surfaces and soil.

A Henry's law constantof 1.81E-04 Pa·m³/mol (at 12 °C) was calculated in EUSES (Vapour pressure 5.504E-03 Pa, 210.3 g/mol molecular weight and 3.42E+03 mg/L water solubility (both at 23 °C).Based on this value the substance has no potential to partition from water to air under environmental conditions (12°C).

Based on Level III environmental distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 31906-04-4 and the measured physico-chemical parameters (3.42E+03 mg/L water solubility and 2.1 log Kow) as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (68.3%) and water (31.6%) with small amounts to air (0.0124%) and sediment (0.0924%).

The SimpleTreat model, which is incorporated in EUSES, simulates the distribution of the substance in a Sewage Treatment Plant (STP) based on vapour pressure, water solubility, log Koc and ready biodegradability. Model calculations show that 86.3% of the substance will be degraded and that 7.24E-05%, 12.5% and 1.2% will partition to air, water and sewage sludge, respectively.
