Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
From the water surface the substance will not evaporate into the atmosphere.
Key value for chemical safety assessment
Additional information
According to the bond estimation method of the HENRYWIN Program (v3.20) of EPI Suite v4.10, the HLC was 1.19E-08 Pa*m³/mol (BASF SE, 2013). The HLC as a function of vapor pressure (0.000338 mm Hg) and water solubility (1.0E+06 mg/L) has a value of 7.355E-06 Pa*m³/mol (BASF SE, 2013). These values are representative for the uncharged molecule. At environmental conditions the molecule is expected to be ionised, therefore a pH-corrected Koc was calculated according to the REACH Guidance document (2008). The resulting Henry's Law constant was 7.50E-12 Pa *m³/mol at pH 7 (range pH 4 to 9: 7.51E-15 to 7.06E-10 Pa*m³/mol; BASF SE, 2013).
Based on the HLC for the charged molecule, 2 -[2 -(3 -aminopropoxy)ethoxy]ethanol will not evaporate from the water surface into the atmosphere.
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.
