Applicant's summary and conclusion

Conclusions:
Neither TBPA nor TBPA-acid are expected to partition from water to air to any significant extent.
Executive summary:

The estimated HLC at 25 deg C for TBPA is 1.6E-7 atm-m3/mole. TBPA-acid, the hydrolysis product of TBPA, has an estimated HLC of 5.5E-14 atm-m3/mole (Bond method).
