Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The bond estimation method gives a value of 5.07E+00 Pa*m³/mol (HENRYWIN Program, v3.20; EPI Suite v4.11; BASF SE, 2013), which is representative for the uncharged molecule. The HLC calculated by vapor pressure and water solubility is 3.20E+01 (HENRYWIN v3.20; EPI Suite v4.11; BASF SE, 2013). At environmental conditions the molecule is expected to be ionised, therefore a pH-corrected HLC was calculated according to the REACH Guidance document (2008). The resulting Henry's Law constant was 1.80 E-03 Pa*m³/mol at pH 7 (BASF, 2013).

Based on the pH-corrected HLC, the substance will not evaporate from the water surface into the atmosphere.
