Description of key information
vapour pressure (whole substance): 0.00012 - 0.04 Pa at 20°C (read-across)
vapour pressure (individual constituents): 4.2E-05 to 1.15E+01 Pa at 25°C (QSAR)
Key value for chemical safety assessment
Additional information
There are no reliable measured vapour pressure data for the registration substance. However, reliable data are available for related substances in the relevant carbon number range, including other Fischer-Tropsch process-derived substances.
In OECD 104 studies using the dynamic method, which were conducted in compliance with GLP, Hydrocarbons, C15-C19, n-alkanes, isoalkanes, <2% aromatics (GS270) had vapour pressure values of 0.04 Pa at 20°C, 0.08 Pa at 25°C and 1.5 Pa at 50°C. Similarly, Hydrocarbons, C18-C24, isoalkanes, <2% aromatics (GS310) had vapour pressure values of 1.2E-04 Pa at 20°C, 3.1E-04 Pa at 25°C and 2.0E-02 Pa at 50°C. The results are considered to be reliable and are used as weight of evidence.
Since the submission substance is a UVCB substance, the vapour pressure of the individual constituents are also important. Measured vapour pressure for the whole substance is preferred for the purpose of human health exposure assessment while the vapour pressure of individual constituents is useful for environmental risk characterisation. The vapour pressure of the individual constituents was determined using a validated QSAR estimation method. Vapour pressure in the range 4.2E-05 to 1.15E+01 Pa at 25°C was determined for the constituents of the submission substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
