Endpoint:
Henry's law constant
Type of information:
calculation (if not (Q)SAR)
Remarks:
Migrated phrase: estimated by calculation
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Estimated using software recommeded in REACH Guidance.
Qualifier:
no guideline followed
Principles of method if other than guideline:
Estimated using software recommended by REACH
GLP compliance:
no
H:
0 atm m³/mol

Estimated by Bond method.

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).

Description of key information

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

Key value for chemical safety assessment
