Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Adsorption / desorption
KOCWIN model of Estimation Programs Interface was used to predict the soil adsorption coefficient i.e Koc value of test chemical. The soil adsorption coefficient i.e Koc value of test chemical was estimated to be 10000000000 L/kg (log Koc=11.2197) by means of MCI method (at 25 deg C). This Koc value indicates that the test chemical has a very strong sorption to soil and sediment and therefore have negligible migration potential to ground water.
Additional information
Adsorption / desorption
Predicted data and various experimental studies of the test chemical were reviewed for the adsorption end point which are summarized as below:
In a prediction done using theKOCWIN Programof Estimation Programs Interface was used to predict the soil adsorption coefficient i.e Koc value of test chemical. The soil adsorption coefficient i.e Koc value of test chemical was estimated to be 10000000000 L/kg (log Koc=11.2197) by means of MCI method (at 25 deg C).
The Soil Adsorption Coefficient i.e Koc value of test chemical was estimated using Adsorption Coefficient module program as Koc 10000000.0 (logKoc = 7) at pH range 1-14, respectively (ACD (Advanced Chemistry Development)/I-Lab predictive module, 2017)).
For the test chemical,adsorption study was conducted for estimating the adsorption coefficient (Koc) value of test chemical (HSDB and PubChem, 2017). The adsorption coefficient (Koc) value was calculated using a structure estimation method based on molecular connectivity indices. The adsorption coefficient (Koc) value of test chemical was estimated to be 10000000000 (Log Koc = 10).
On the basis of above overall results for test chemical, it can be concluded that the log Koc value of test chemical was estimated to be ranges from 7 to 11.2, respectively, indicating that the test chemical has a very strong sorption to soil and sediment and therefore have negligible migration potential to ground water.
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).
