Description of key information

Henry's Law constant for BBP using a QSAR calculation was estimated to be 0.00428 Pa m³/mol (Bond Estimation Method) and 0.000216 Pa m³/mol (Group Estimation Method). The value calculated from experimental vapour pressure and water solublity data is 0.127 Pa m³/mol.

Key value for chemical safety assessment

Additional information

Experimental Henry’s Law Constant data is not available for benzyl butyl phthalate. Therefore QSAR have been used to calculate the Henry’s Law Constant. Henry's Law constant for benzyl butyl phthalate using a QSAR calculation was estimated to be 0.00428 Pa m³/mol (Bond Estimation Method) and 0.000216 Pa m³/mol (Group Estimation Method). The value calculated from experimental vapour pressure and water solubility data is 0.127 Pa m³/mol.
