Description of key information
The adsorption potential of the substance was determined in a study according to OECD TG 106 (Batch Equilibrium Method). Under the conditions of the test, the log Koc of the substance was determined at 3.70 (equivalent Koc = 4923 L/kg). Based on this value the substance has potential for adsorption to solid surfaces and soil.
A Henry's law constant of 0.439 Pa·m³/mol (at 12 °C) was calculated in EUSES (Vapour pressure 1.6E-02 Pa (at 25°C), 242.36 g/mol molecular weight and 3.95 mg/L water solubility (at 20 °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 Smiles( CC3(C)C2=C(CCc1cncnc12)C(C)(C)C3C ) and the measured physico-chemical parameters (3.95 mg/L water solubility and 5.11 log Kow) as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (71.5%), water (10.3%) and sediment (18.1%) with small amounts to air (0.0319%).
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 none of the substance will be degraded and that 0.483%, 62.6% and 36.9% 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
