Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
KOCWIN v2.00 was used to calculate the LogKoc value for the main representative constituents of EC 903-162-9, basedon this output a worst case value 8.5933 will be used for the purposes of the chemical safety assessment.
Key value for chemical safety assessment
- Koc at 20 °C:
- 10 000 000
Additional information
Considering the difficult structure of the substance and the surface active properties the estimation method is the most appropriate method for calculating the Koc valuet.Due to the nature of the substance - organic and inorganic parts in the molecules - the analytics is very complex. Therefore QSAR calculations were performed to support the experimental results. For these calculations only the organic part of the constituents has been considered in the non-ionic form.
Based on the calculations for the main constituents of EC 903-162-9, LogKoc values ranging from 9.3388 to 13.8343 MCI Method and 8.5933 to 12.5159 (Log Pow Based Estimate) were derived (see atachment for full result details). For the purposes of the chemical safety assessment, a LogKoc value of 7 has been selected, as this is the maximum value that is in the domain of the EUSES model.
[LogKoc: 7.0]
