Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The adsorption coefficient (Koc) of the substance URACROSS P3307 is 1252 (log Koc = 3.10). Since the registered substance and the substance URACROSS P3307 both contain the same main component, the value for this constituent of the registered substance is also 1252 (log Koc = 3.10). See the full read-across report in IUCLID section 13 for details.
In addition, the Koc of the other constituent of the registered substance was calculated to be 6705 (log Koc = 3.83). See the full read-across report in IUCLID section 13 for details.
Key value for chemical safety assessment
Additional information
Key values for chemical safety assessment:
Koc (main constituent): 1252 L/kg
Koc (other constituent): 6705 L/kg
The adsorption coefficient (Koc) of the substance URACROSS P3307 was determined using the HPLC method and the corresponding value was 1252 (log Koc = 3.10).
This adsorption estimation study is considered to be reliable without restrictions since it fully satisfies the requirements of OECD Guideline No. 121.Since the registered substance and the substance URACROSS P3307 both contain the same main component, the value for this constituent of the registered substance is also 1252 (log Koc = 3.10). See the full read-across report in IUCLID section 13 for details. In addition, the Koc of the other constituent of the registered substance was calculated to be 6705 (log Koc = 3.83).
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.
