Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:

The Soil Adsorption Coefficient i.e. Koc value of test chemical  was estimated using EPI suite KOCWIN Program (v2.00) as 260 L/kg (log Koc= 2.094 ) by means of MCI method at 25 deg. C.  This log Koc value indicates that test chemical has low sorption to soil and therefore test chemical has moderate migration potential to ground water.

Additional information

Adsorption/desorption:

Different studies have been reviewed for Adsorption endpoint for test chemical and its read across chemicals and their results are summarized below.

In first study the Soil Adsorption Coefficient i.e. Koc value of test chemical  was estimated using EPI suite KOCWIN Program (v2.00) as 260 L/kg (log Koc= 2.094 ) by means of MCI method at 25 deg. C.  

To support the result of above study another study was reviewed from authoritative database (HSDB) in this study the adsorption coefficient (Koc) value was calculated using a structure estimation method based on molecular connectivity indices. The adsorption coefficient (Koc) value of test substance was estimated to be 260 dimensionless (Log Koc = 2.4149).

Last study was also reviewed from same source as mentioned above (HSDB) in this study the adsorption coefficient (Koc) value was calculated using a measured water solubility of 200 mg/l and a regression-derived equation. The adsorption coefficient (Koc) value of test substance was estimated to be 240 dimensionless (Log Koc = 2.3802).

By considering the results of all the studies mentioned above it is concluded that Log Koc value of test chemical is in range of 2.094- 2.4149 and this range log Koc value indicates that the substance has a low sorption to soil and sediment and therefore has moderate migration potential to ground water.
