- Vapour pressure:
- ca. 34 Pa
- Remarks on result:
- other: Calculated extrapolated value
- Conclusions:
- Under the study conditions, the vapour pressure of the test substance was determined to be 34 Pa at 20°C.
- Executive summary:
A study was conducted to determine the vapour pressure of the test substance using the static method, according to EC Method A.4, in compliance with GLP. For test run 1, test substance was degassed over a period of 3 h at -10°C. During testing, there was temperature equilibration but pressure equilibration was not achieved after 24 h. The testing was therefore test was terminated. For test run 2, the test substance was ground and placed under vacuum for 15 h. Under the study conditions, the vapour pressure of the test substance was extrapolated to be 34 Pa at 20°C (Chilworth, 2017).

Comment
For test run 1, test substance was degassed over a period of 3 h at -10°C.
During testing, there was temperature equilibration but pressure equilibration was not achieved after 24 h. The testing was therefore test was terminated.
For test run 2, the test substance was ground and placed under vacuum for 15 h.
Description of key information
The vapour pressure of the test substance was determined experimentally using static method, according to the EU A.4 Method (Chilworth, 2017) as well using QSAR models EPI Suite and T.E.S.T (US EPA, 2018).
Key value for chemical safety assessment
- Vapour pressure:
- 0.001 Pa
- at the temperature of:
- 25 °C
Additional information
- Experimental VP: 34 Pa (using static method); the VP value is suspected to be influenced by trapped gases/impurities.
- Weighted average QSAR based VP = 0.000568 Pa at 25°C (using EPI Suite v.4.11); 0.00125 Pa at 25°C (using T.E.S.T. v4.2.1). The estimates for the major constituents are considered to be reliable with restrictions, as they do not completely fall within of the applicability domain.
- VP values for the main constituents, phosphate esters (PSE) and alcohol: 0.00289 Pa at 20°C (using effusion method) for mono- and di- C16 PSE, K+ (ECHA REACH dossier on CAS 19035-79-1); 0.0013 Pa at 25°C (calculated from composition) for alcohols, C16-18 (OECD SIDS, 2006) respectively.
Overall, based on the above information the test substance can be considered to have low volatility potential. In absence of a reliable experimental value and the fact that the constituent alcohol, make up more than 80% of the composition, the VP value of the alcohol, which is 0.0013 Pa at 25°C, has been considered further for hazard/risk assessment as a conservative approach.
