Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Log Koc and Koc of OS9600 should be understood based on its degradation product MPKO since it undergoes rapid hydrolysis (half-life < 1h) and the study is not technically feasible. The koc and log of MPKO was <20.9 and <1.32 respectively (OECD 121, GLP).
Key value for chemical safety assessment
- Koc at 20 °C:
- 20.9
Additional information
Data waiving (study not technically feasible): The study is technically not feasible since the substance is hydrolytically unstable (half-life < 1h).
Supporting study: The adsorption coefficient (log Koc) of MPKO was determined by means of HPLC in accordance with OECD Guideline 121 and EU Method C19 (GLP study). The Koc and log Koc value of the test substance at neutral pH were determined to be < 20.9 and <1.32 respectively.
[LogKoc: 1.32]
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).
