Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 / desorption (Koc) is calculated to be 2010 L/kg (Log Koc is 3.3) based on the Koc-QSAR for esters incorporated in EUSES, with the log Kow of 4.6 as input.
The Henry's law constant is calculated using the equation from EUSES. Using a molecular weight of 196 g/mol, and the experimentally determined vapour pressure of 2.12 Pa (at 24 °C) and water solubility of 28.8 mg/L (at 24 °C), the Henry's Law constant at environmental temperature (12 °C) is calculated to be 7.29 Pa·m³/mol. The substance is not expected to volatilise from water to a significant extent.
Based on Level III environmental distribution modelling using EPISUITE for all constituents (assuming equal and continuous releases to air, water and soil), using the EPISuite default physico-chemical parameters for each constituent as input, it is estimated that the majority of the constituents released to the environment will partition mainly into soil (ca. 79.3%) and water (ca. 20.2%) with minor amounts to sediment (ca. 0.4%) and air (0.05%).
The SimpleTreat model, which is incorporated in EUSES, simulates the distribution of the substance in a Sewage Treatment Plant (STP). Model calculations show that 72.6% of the substance will be degraded and that 15.0%, 10.3% and 2.1% will partition to sewage sludge, water and air, 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.
