vapour pressure
Type of information:
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Internationally accepted method, EPI-Suite, EPA (USA)
Justification for type of information:
According to column 2 of REACH Annex VII, If the melting point is between 200 °C and 300 °C, a limit value based on measurement or a recognised calculation method is sufficient.
A calculation method thus has been chosen. See attached the QMRF and QPRF for the QSAR model.
Reason / purpose for cross-reference:
other: justification for using a calculation method
other: REACH Guidance on QSARs R.6
Principles of method if other than guideline:

Specific details on test material used for the study:
Key result
25 °C
Vapour pressure:
0.057 Pa
Remarks on result:
other: QSAR predicted value

MPBPVP predicted that isoborneol has a VP of 0.0572 Pa.

The estimated vapour pressure at 25 ºC is 0.0572 Pa (EPI-Suite, MPBPVP v1.43)
Executive summary:

The estimated vapour pressure at 25 ºC is 0.0572 Pa (EPI-Suite, MPBPVP v1.43)
