Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- adsorption / desorption: screening
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: authoritative database
- Justification for type of information:
- data from authoritative databse
- Qualifier:
- according to guideline
- Guideline:
- other: refer below principle
- Principles of method if other than guideline:
- To estimate the log Koc of test chemical
- GLP compliance:
- not specified
- Media:
- soil
- Key result
- Type:
- Koc
- Value:
- 240 L/kg
- Remarks on result:
- other: log Koc value -2.38
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The Log Koc value was estimated to be 2.38. Thus based on the result it is concluded that the test substance has low sorption to soil and sediment and therefore has moderate migration potential to ground water.
- Executive summary:
The Koc of test chemical is estimated by using a measured log Kow of 1.83 and a regression-derived equation.The Koc is estimated as approximately 240 L/kg ,the Log Koc value was determined to be 2.38. Thus based on the result it is concluded that the test substance has low sorption to soil and sediment and therefore has moderate migration potential to ground water

Description of key information
The Log Koc value was estimated to be 2.38. Thus based on the result it is concluded that the test substance has low sorption to soil and sediment and therefore has moderate migration potential to ground water.
Key value for chemical safety assessment
Additional information
Following different studies includes estimated study for the target chemical to observe the Adsorption of test chemical.
In first study (HSDB) the Koc of test chemical is estimated by using a measured log Kow of 1.83 and a regression-derived equation. The Koc is estimated as approximately 240 L/kg .The Log Koc value was determined to be 2.38. Thus based on the result it is concluded that the test substance has low sorption to soil and sediment and therefore has moderate migration potential to ground water.
The Soil Adsorption Coefficient i.e. Koc value of test chemical was estimated using EPI suite KOCWIN Program (v2.00) as 184.5L/kg (log Koc= 2.26) 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.
Thus based on the above results it is concluded that the test substance has low sorption to soil and sediment and therefore has moderate migration potential to ground water...
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
