Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Soil Adsorption Coefficient i.e Koc value of tert-butyl-4-methoxyphenol was estimated as 840.7 L/kg by means of MCI method. This indicates that tert-butyl-4-methoxyphenol will adsorb to the organic carbon fraction of the soil and will have a slight tendency to move with the water content in the soil. This value is further modified to be 672.56 at 20 degree celcious.
This value of 840.7 when converted at 20°C works out to be 672.56.
Key value for chemical safety assessment
- Koc at 20 °C:
- 672.56
Additional information
The supporting study shows value different from the key study which could be due to the difference in the estimation conditions.
However, for the purpose of the dossier as well as for the chemical safety report the experimental value will be considered.

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.
