Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 log Koc values for the three main constituents of the substance representing more than 85% of all the components are 8.9-11, 9.5-16.9 and 7.9-8.
Key value for chemical safety assessment
- Koc at 20 °C:
- 79 432 823 472 427 888
Additional information
The adsorption/desorption coefficients of this complex reaction product were calculated according to the recommended QSAR model Kocwin v2.0, based on Molecular Connectivity Index and on log Kow value.
More than 85% of all the components have adsorption/desorption coefficient values ranged from 7.9 to 16.9.
The components with log Koc values between 7.9 and 16.9 being the most abundant (>85%),the highest log Koc value (16.9) in this range was used for chemical safety assessment (CSA) and for the derivation of Predicted No-Effect Concentrations (PNEC) in sediments and soil.
This value was considered as a worst-case value, increase of adsorption/desorption coefficient value leading to a significant increase of the PEC soil value.
[LogKoc: 16.9]
