The vapour pressure of the test substance was determined experimentally using the static method, according to EU A.4 Method (Chilworth, 2017) as well using QSAR model EPI Suite (US EPA, 2018).

Vapour pressure:
4 Pa
at the temperature of:
20 °C

- Experimental VP = 4 Pa at 20 °C (using static method);

- QSAR based VP = The predicted values ranged from 4.71E-18 to 1.19E-32 Pa for the different constituents which could be generically represented as <1.3E-4 Pa at 25°C (using EPI Suite v.4.11). The estimates for the major constituents are considered to be reliable with restrictions, as they do not completely fall within of the applicability domain.

Overall, based on the above information, the test substance can be considered to have low volatility potential. However, the higher VP value of 4 Pa has been considered further for hazard/risk assessment as a conservative approach.
