Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The distribution coefficient on soil (log Koc) was estimated to be between 2.16 and 3.73 at 25 °C using the HPLC simulation technique, all within a 95% confidence range of 1.74 to 4.12. The average log Koc value of 2.95 will be used in the assessment.
The Henry's law constant (H) estimated using the vapour pressure of 4,361 Pa at 20 °C and water solubility 3,917 mg/l at 20 °C, is 129 Pa m3/mol (log H = 2.11). The calculated Henry's law constant value indicates that TAEE volatises easily from water to air. The corresponding value of 72.9 Pa m3/mol at 12 °C will be used in the assessment.
Using a fugacity model (Mackay Level I), the theoretical distribution of TAEE based on physico-chemical properties between four environmental compartments at equilibrium can be calculated. The results indicate that 93.1% is distributed to the atmosphere and that volatilisation may be expected from water and soil and adsorption to particulate matter is poor.
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.
