Details on test material:
SMILES notation used: CC(CCCCCCCOC(=O)(c1cc(C(=O)(OCCCCCCCC(C)C))c(C(=O)(OCCCCCCCCCCC(C)C))cc1))C. This represent one of many possible isomeric structures for the ester reaction products of isodecyl and isotridecyl alcohols with trimellitic anhydride, the registrant test substance.

EPI Suite v4.11 estimated vapor pressure value of 1.35 e-12 Pa or 1.01 e-14 mm Hg at 25 C

Applicant's summary and conclusion

Conclusions:
The test substance was estimated to have a vapor pressure of 1.35 e-12 Pa at 25 C using the US EPA EPI Suite v4.11 (modified Grain method). These results indicate that the test substance is expected to have an extremely low vapor pressure and is expected to be non-volatile at room temp.
Executive summary:

The test substance was estimated to have a vapor pressure of 1.35 e-12 Pa at 25 C using the US EPA EPI Suite v4.11 (modified Grain method). These results indicate that the test substance is expected to have an extremely low vapor pressure and is expected to be non-volatile at room temp.
