Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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
