Description of key information
From the water surface the substance will not evaporate into the atmosphere.
Key value for chemical safety assessment
- at the temperature of:
- 25 °C
Additional information
The Henry's Law Constant was calculated based on measured data for the vapour pressure and water solubility. The HLC resulted in a value of 2.52 E-07 Pa*m³/mol. This indicates that the substance will not evaporate from the water surface into the atmosphere. The bond estimation method gives a value of 0.615 Pa*m³/mol (HENRYWIN Program, v3.20; EPI Suite v4.10; BASF SE, 2011), which is 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 7.72 E-09 at pH 7 (BASF, 2011).
Based on the pH-corrected HLC, the substance will not evaporate from the water surface into the atmosphere.
