Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
adsorption coefficient (Koc) of the test material: >4.27 x 10E5, log10 Koc >5.63
Key value for chemical safety assessment
- Koc at 20 °C:
- 5.63
Additional information
EUSES 2.1.2 includes TGD equations for the prediction of the adsorption coefficient Koc from Kow. The appropriate equation is for the ‘hydrophobics’ group, which is:
log Koc= 0.10 + 0.81log Kow
Kocfor each constituent is calculated from the log Kow . The calculated values are presented in Table 4.2.1 of the CSR.
A study was performed according to EU test method C19 (HPLC method) in which the adsorption coefficient for Distillates (Fischer-Tropsch), C8-26, branched and linear was reported to be greater than 4.27E+05 (log Koc>5.6) (O’Connor and Mullee, 2006). This result is also relevant to Hydrocarbons, C16-C22, n-alkanes, isoalkanes, <2% aromatics.
Adsorption coefficients for individual constituents is described in Section 4.2.1 of the Chemical Safety Report attached in Section 13.
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.
