The vapour pressure of the test substance was determined using the static method, according to EU Method A.4, (Chilworth, 2017) as well using three QSAR i.e., EPI Suite v.4.11, US EPA T.E.S.T (US EPA, 2018) and ChemProp (UFZ, 2018).
In absence of a reliable experimental study with the test substance, the vapour pressure (VP) endpoint has been assessed based on the below weight of evidence:
- Experimental VP = 6.6 Pa at 20 °C; the measured VP value is considered to be reliable with restrictions, as it can be suspected to be influenced by trapped gas/solvent/impurities.
- Estimated VP = 1.59E-11 Pa at 25°C (using modified grain method of EPI Suite v.4.11 program); 7.38E-7 at 25°C (using consensus method of T.E.S.T. v.4.2.1); the estimates are considered to be reliable with restrictions, as they do not completely fall within of the applicability domain. Also, the two QSAR models are not powered enough to predict ionic substances. Therefore the VP was estimated using a third QSAR model, ChemProp v.6.0, which resulted in VP values 5.75E-5 Pa and 1.12E-7 Pa at 25°C using modified Grain Antoine and modified Grain Watson methods respectively.
- Experimental VP of structurally similar substance, C12-16 ADBAC: 1.5E-03 Pa at 20°C and 1.58E-3 Pa at 25°C (ECHA REACH dossier; EC: 939-253-5).
Overall, based on the available weight of evidence, the test substance can be considered to have low volatility. However, in absence of a reliable experimental value, the higher QSAR based VP value (i.e., 5.75E-5 Pa) at25°C has been considered further for hazard/risk assessment.
