Description of key information

A study on vapour pressure does not need to be conducted.

Key value for chemical safety assessment

Additional information

According to REACH Annex XI, 2. the determination of the vapour pressure of AAPB is not necessary, because it is technically not possible: the expected value of vapour pressure for the pure substance cannot be measured due to residual content of solvent (water, isopropanole) which results in a higher solvent vapour pressure than test substance vapour pressure. The residual content of solvent cannot be reduced below the limit of measurement with reasonable effort.
