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.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
