Conclusions:
Under the conditions of the study, the vapour pressure was determined to be 6.0E-5 Pa (or 4.5E-7 mmHg) and 1.1E-4 Pa (or 8.0E-7 mmHg) at 20°C and 25°C, respectively.
Executive summary:

A study was conducted to determine the vapour pressure of the test substance, C18-unsatd. DEA, using an isothermal thermogravimetric effusion method according to OECD Guideline 104, EU Method A.4 and US EPA Guideline 830.7950. Under the conditions of the study, the vapour pressure was determined to be 6.0E-5 Pa (or 4.5E-7 mmHg) and 1.1E-4 Pa (or 8.0E-7 mmHg) at 20°C and 25°C, respectively (Baltussen, 2012).

Endpoint:
vapour pressure
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
QSAR prediction from a well-known and acknowledged tool. See below under ''attached background material section' for QPRF containing methodology and domain evaluation details.
Qualifier:
according to guideline
Guideline:
other: REACH guidance on QSARs: Chapter R.6. QSARs and grouping of chemicals
Principles of method if other than guideline:
The vapour pressure (VP) value for the test substance were estimated using the Modified Grain method of the MPBPWIN v1.44 program in EPI SuiteTM v4.11. Since the test substance is a UVCB, the VP values were predicted for the individual constituents using SMILES codes as the input parameter.
Type of method:
other: Modified Grain method (using the MPBPWIN v1.44 program in EPI SuiteTM v4.11)
Key result
Temp.:
25 °C
Vapour pressure:
ca. 0 - ca. 0 Pa
Remarks on result:

Key result
Temp.:

Remarks on result:
other: weighted average vapour pressure (indicating low vapour pressure or volatility)

Predicted value:

The estimated VP values for the remaining constituents using the modified grain method were as follows:

*Glycerol or DEA residues have not been considered for QSAR predictions

** Since the predicted VP values are lower than the cut-off VP value, below which the chances of introduction of error increases, the VP values are simpilfied and presented as less than the cut-off, instead of the individual predictions.

Conclusions:
Using the Modified Grain method, of MPBPWIN v1.44 program of EPI SuiteTM, the weighted average VP value for test substance was predicted to be <1.34E-4 Pa at 25°C.
Executive summary:

The vapour pressure (VP) of the test substance, C18-unsatd. DEA, was predicted using the Modified Grain method of the MPBPWIN v1.44 program (EPI SuiteTMv4.11). Since the test substance is a UVCB, the VP values were predicted for the individual constituents using SMILES codes as the input parameter. Using the Modified Grain method, the VP values for the individual constituents of the test substance ranged from 1.10E-12 to 2.37E-06 Pa at 25°C (original estimates) (US EPA, 2019). Since not all constituents meet the boiling point (BP) and VP molecular descriptor domain criteria as defined in the MPBPVP user guide of EPI Suite TM, the VP predictions were considered to be less accurate. As the test substance is a UVCB, individual experimental BP values are not available to be used in order to reduce the uncertainty. However, for the VP parameter the chances of introducing errors when the predicted VP values were below the cut-off set by the tool, was reduced by substituting the individual VP values as less than the cut-off value (i.e., <1.34E-4 Pa). Further, given that the constituents are structurally very similar and vary only in the carbon chain length, a weighted average value, which considers the percentage of the constituent in the substance, was considered to dampen the errors in predictions (if any). Therefore, the weighted average VP value was calculated as <1.34E-4 Pa, indicating the test substance to have a low volatility potential (ECHA, 2017) and low fugacity (ECHA, 2009), leading to low inhalation exposure to users and environmental exposure through air or via volatilization from water. Overall, the VP predictions for the test substance using MPBPVP model of EPI Suite TM can be considered to be reliable with low to moderate confidence.

Conclusions:
Using the Consensus method, of T.E.S.T. v4.2.1 program, the weighted average VP value for test substance was predicted to be 3.89E-09 Pa at 25°C.
Executive summary:

The vapour pressure (VP) of the test substance, C18-unsatd. DEA, was calculated using the Consensus method of T.E.S.T. v4.2.1 program. Since the test substance is a UVCB, the VP values were predicted for the individual constituents using SMILES codes as the input parameter. Using the Consensus method, the predicted VP values of the constituents ranged from 8.73E-09 to 1.76E-03 Pa at 25 °C, indicating a low vapour pressure (US EPA, 2019). As not all constituents were within the MW or the structural fragment domain criteria as defined in the T.E.S.T. user guide of EPA, the VP predictions were considered to be less accurate. Given that the constituents are structurally very similar and vary only in the carbon chain number, a weighted average value, which takes into account the percentage of the constituent in the substance, was calculated to dampen the errors in predictions. The weighted average VP value was calculated as 3.89E-09 Pa at 25 °C. Therefore, considering either the individual VP predictions for the constituents or the weighted average values, the overall test substance is expected to have a low volatility potential (ECHA, 2017) and low fugacity (ECHA, 2009), leading to low inhalation exposure to users and environmental exposure through air or via volatilization from water. Further, based on the mean absolute error (MAE) criteria, the prediction accuracy was considered to be moderate. Therefore, the VP predictions for the test substance using T.E.S.T. model overall can be considered to be of reliable with low to moderate confidence.

Description of key information

The vapour pressure was determined according to OECD Guideline 104 and EU Method A.4 (Baltussen, 2012).

Weighted average vapour pressure values for the test substance were also modelled using the Modified Grain method of MPBPWIN v1.44 program of EPI Suite and the Consensus method of the T.E.S.T. v4.2.1 program.

Key value for chemical safety assessment

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

Additional information

The measured vapour pressure was 6.0E-5 Pa at 20°C. 

Using the Modified Grain method of the MPBPWIN v1.44 program of EPI Suite, the weighted average vapour pressure for the test substance was predicted to be <1.34E-4 Pa at 25°C. According to the Consensus method of the T.E.S.T. v4.2.1 program, the weighted average vapour pressure was 3.89E-9 Pa at 25°C. 

The measured vapour pressure was retained as key value for risk assessment purposes.
