Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Koc values of between 3500 and 18000 l/kg determined in laboratory experiments (Johnson et al., 1998) show that Octylphenol (OP) tends to adsorb strongly onto organic matter. Therefore, adsorption is likely to play an important role as a sequestration process in soil, sediment, and sewage sludge. Adsorption to solids such as sediments and sewage sludge is likely an important removal process for OP.
The available data suggest that volatilization of OP is likely to be a removal process from water which is of low to medium importance (HLC of 0.52 Pa m³/mol at 298 K).
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.
