Comment

Run 1

Test substance was degassed for 15 h. Initial pressure was 0.0055 mbar. The plot of Log P vs 1/T shows a curve starting at about 50°C. This could be due to a phase change i.e. the test substance changing from solid to liquid. Consequently it is recommended that the value taken as a direct reading at 20 °C is reported.

 

Run 2

Test substance was degassed for 14 h. Initial pressure was 0.0035 mbar.

Conclusions:
Under the study conditions, the vapour pressure of the test substance was determined to be 250 Pa at 20°C.
Executive summary:

A study was conducted to determine the vapour pressure of the test substance, iso and anteiso C10-40 AAP EDM-ES, using the static method, according to EU Method A.4, in compliance with GLP. In the run 1 (degassed - 15 h, Initial pressure - 0.0055 mbar) and run 2 (degassed - 14 h, Initial pressure 0.0035 mbar), result values obtained were 250 and 250 Pa at 20°C respectively. Based on the study results, mean vapour pressure value was determined to be 250 Pa at 20°C. Under the study conditions, the vapour pressure of the test substance was determined to be 250 Pa at 20°C (Chilworth, 2017). Such high vapour pressure is not expected for the test substance given its composition, therefore it is suspected to be influenced by trapped gas/impurities.

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:
Please use QSAR prediction from an well known and acknowledged tool. See below under 'Overall remarks, attachments' for applicability domain.
Qualifier:
according to
Guideline:
other: REACH guidance on QSARs: Chapter R.6. QSARs and grouping of chemicals
Principles of method if other than guideline:
Since the test substance is a UVCB with similar constituents varying mainly in carbon chain lengths, the vapour pressure values were estimated for the individual components followed by the determination of an overall weighted-average value using the mole fractions of all the individual components.

Conclusions:
Using the Modified Grain method of the MPBPWIN v1.43 program (EPI Suite v4.11), the weighted average vapour pressure of the test substance was calculated to be 1.79E-16 Pa.
Executive summary:

The vapour pressure (VP) value for the test substance, 'iso and anteiso C10-40 AAP EDM-ES', were estimated using the Modified Grain method of the MPBPWIN v1.43 program (EPI Suite v4.11). Since the test substance is a UVCB with similar constituents varying mainly in carbon chain lengths, the vapour pressure values were estimated for the individual components followed by the determination of an overall weighted-average value using the mole fractions of all the individual components. SMILES codes were used as the input parameter for the vapour pressure estimation for the individual constituents. The weighted average vapour pressure value of the test substance was 1.79E-16 Pa (US EPA, 2018). Based on calculated value, the test substance is considered as having low volatility property (ECHA, 2017). The estimates for the major constituents are considered to be reliable with restrictions, as they do not completely fall within of the applicability domain.

Description of key information

Vapour pressure of the test substance was determined using the static method according to EU Method A.4 (Chilworth, 2017) as well as using MPBPWIN v.1.43 QSAR models of EPI Suite v.4.11 (US EPA, 2018).

Key value for chemical safety assessment

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

Additional information

Experimental VP of the test substance: 250 Pa at 20°C (using static method). Such high vapour pressure is not expected for the test substance given its composition, therefore it is suspected to be influenced by trapped gas/impurities.

Weighted average estimate VP of the test substance: 1.79E-16 Pa (using MPBPWIN v1.43 program of EPI Suite v4.11). The estimates for the major constituents are considered to be reliable with restrictions, as they do not completely fall within of the applicability domain.

Experimental VP of structurally similar substance, C18-unsatd. and C22-unsatd. AAP EDM-ES: <100 Pa at 20°C (using isoteniscope method).

Overall, based on the above information, the test substance can be considered to have low volatility potential. However, the higher VP value of 250 Pa has been considered further for hazard/risk assessment.
