Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Key value for chemical safety assessment
Additional information
Phototransformation in air:
The SRC AOPWIN program was used to obtain values of the rate constant kOHfor reaction of each constituent with hydroxyl radicals. An overall half-life in air under default conditions of hydroxyl radical concentration can be calculated using the following expressions:
kdegair(d-1) = kOH(cm3/molecule-sec) x OHConcair(molec/cm3) x 24 x 3600
Half-life is then calculated as:
DT50(d) = ln 2/ kdegair(d-1)
Where:
kdegair= total rate constant for degradation in air
kOH= rate constant for reaction with hydroxyl radicals
OHConcair= concentration of hydroxyl radicals in air
DT50= half-life
Calculated values for the constituents of Alkanes, C16 -C18 branched and linear are presented in Table 4.2.1 of the Chemical Safety Report.
Phototransformation in water
Phototransformation in water is not expected to be a significant removal process for Alkanes, C16 -C18 branched and linear.
Phototransformation in soil
Phototransformation in soil is not expected to be a significant removal process for Alkanes, C16 -C18 branched and linear.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
