Conclusions:
The estimated vapor pressure of di-TMPTTA using EPISUITE software (MPBPWIN v1.43) is 0.0000013 Pa at 20 °C (i.e., mean of Antoine, Grain and Mackay methods).
Executive summary:

The vapour pressure of di-TMPTTA was estimated by calculation with EPISUITE software (MPBPWIN v1.43). Based on the results obtained from this software, the mean vapour pressure was determined to be 0.0000013 Pa at 20 °C (i.e., mean of Antoine, Grain and Mackay methods) (Jeuniaux, 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 an well known and acknowledged tool. See below under ''attached background material section' for QPRF.
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 the number of acrylates TMP backbone as well as adduct formation) vapour pressure values were predicted for the individual constituents (present at >5%) followed by the determination of an overall weighted average using the mole fractions.

 [1] As per the EPISuite help manual for MPBPWIN, the complete training sets for MPBPWIN's estimation methodology are not available. Therefore, describing a precise estimation domain for this methodology is not possible. However, the current applicability of the MPBPWIN methodology can be best described by its accuracy in predicting vapor pressure, which is based on the boiling point and melting point data apart from MW. Therefore, for the current domain evaluation, a Molecular weight (Training and validation dataset): 16.04 - 943.17 g/mol; Boiling point cut off (deg C): 226.85 deg C; Melting point cut off (deg C): 350 deg C; Vapour pressure cut off (Pa): 0.0001333 Pa have been used.

Conclusions:
Using the Modified Grain method of the MPBPWIN v1.44 program (EPISuite v4.11), the VP values ranged from 3.89E-26 to 2.84E-06 Pa at 25°C, leading to a weighted average value of 1.55E-6 Pa for the test substance.
Executive summary:

The vapour pressure (VP) value for the test substance were estimated using the Modified Grain method of the MPBPWIN v1.44 program (EPI Suite v4.11). Since the test substance is a UVCB with similar constituents (varying mainly in the number of acrylates TMP backbone as well as adduct formation) vapour pressure values were predicted for the individual constituents (present at >5%) followed by the determination of an overall weighted average using the mole fractions. SMILES codes were used as the input parameter for the vapour pressure estimation for the individual constituents. The VP values ranged from 3.89E-26 to 2.84E-06 Pa at 25°C leading to a weighted average value of 1.55E-6 Pa for the test substance (US EPA, 2018). Based on calculated value, the test substance is considered as having low volatility property (ECHA, 2017). The VP predictions are considered to be less accurate or reliable with restrictions, as not all constituents are falling into the applicability domain.

[1] As per the T.E.S.T Guide, currently no definition of model domain is available. However, confidence in predicted value is increased, if the MAE (mean absolute error) values for similar chemicals (≥0.5) is lower or equal to the MAE for the external and training dataset, which were determined to be 0.47 and 0.40, respectively.

For detailed results, kindly refer the attached background material section.

Conclusions:
Using the FDA Consensus method of the T.E.S.T. v4.2.1 program, the VP values ranged from 2.95E-09 to 1.33E-01 Pa at 25 degrees leading to a weighted average value of 7.42E-02 Pa for the test substance.

Executive summary:

The vapour pressure (VP) value for the test substance were estimated using the Consensus method of the T.E.S.T. v4.2.1 program. Since the test substance is a UVCB with similar constituents (varying mainly in the number of acrylates TMP backbone as well as adduct formation) vapour pressure values were predicted for the individual constituents (present at >5%) followed by the determination of an overall weighted average using the mole fractions. SMILES codes were used as the input parameter for the vapour pressure estimation for the individual constituents. The VP values ranged from 2.95E-09 to 1.33E-01 Pa at 25 degrees leading to a weighted average value of 7.42E-02 Pa for the test substance (US EPA, 2018). Based on calculated value, the test substance is considered as having low volatility property (ECHA, 2017). The VP predictions are considered to be less accurate or reliable with restrictions, as the mean absolute error (MAE) values for all constituents were not below the value for the entire test set.

Additional information

Predicted VP from MPBPWIN v.1.44 of EPiSuite v.4.11: VP range: 3.89E-26 to 2.84E-06 Pa at 25°C; weighted average: 1.55E-06 Pa at 25°C. di-TMPTTA predictions at higher temperatures: 5.25E-04 Pa at 60°C; 1.88 E-03 Pa at 70°C

Predicted VP from US EPA T.E.S.T v.4.2.1: VP range: 2.95E-09 to 1.33E-01 Pa at 25°C; weighted average: 2.96E-03 Pa at 25°C.

Based on the individual or weighted average VP predictions from EPISuite and T.E.S.T, the test substance is overall considered to have low volatility. The individual prediction for the most volatile constituent, di-TMPTTA, which is also the major constituent of the test substance present at 20-70%, has been considered, to represent the worst case scenario. However, given that the test substance has operating conditions at higher temperatures (such as 60 and 70°C), and that the T.E.S.T QSAR model only allows prediction at 25°C, the individual VP predictions for di-TMPTTA at 25°C and higher temperatures from EPISuite, has been considered further for risk assessment.
