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 determined in a study according to OECD TG 121 (HPLC method). Under the conditions of the test, the log Koc of the substance was determined to range from 1.58 to 4.25 (equivalent Koc = 38.3 - 17700 L/kg), the main constituent detected, contributing to 84% of the total content analysed by HPLC, had a Koc value of 2089.3 L/kg (log Koc 3.32). Based on this value it may be concluded that the substance has significant potential for adsorption to solid surfaces and soil.

A Henry's law constant of 19.7 Pa·m³/mol (at 12 °C) was calculated in EUSES (MW = 168.28; Vap pressure 6.04 Pa (24°C); 26.1 mg/l water solubility (24°C). Based on this value the substance has potential to partition from water to air.

Based on Level III environmental distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 58296 -81 -4 and the measured physico-chemical parameters (water solubility and log Kow) as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (73.1%) and water (26.4%) with small amounts to air (0.32%) and sediment (0.17%).

The SimpleTreat model simulates the distribution of the substance in a Sewage Treatment Plant. Model calculations (default assumptions, local) show that 70.4% of the substance will be degraded and that 9.7%, 15.3%, and 4.6% will partition to water, sludge and air, respectively.
