- Key result
- Type:
- Koc
- Value:
- 13.4 L/kg
- Temp.:
- 25 °C
- Remarks on result:
- other: logKoc = 1.1271 (estimated by MCI method)
- Transformation products:
- not specified
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The Soil Adsorption Coefficient i.e. Koc value of test chemical was estimated using EPI suite KOCWIN Program (v2.00) as 13.4 L/kg (log Koc= 1.1271) by means of MCI method at 25°C. This log Koc value indicates that test chemical has negligible sorption to soil and therefore test chemical have a rapid migration potential to ground water.
- Executive summary:
The Soil Adsorption Coefficient i.e. Koc value of test chemical was estimated using EPI suite KOCWIN Program (v2.00) as 13.4 L/kg (log Koc= 1.1271) by means of MCI method at 25°C. This log Koc value indicates that test chemical has negligible sorption to soil and therefore test chemical have a rapid migration potential to ground water.

Description of key information
The Soil Adsorption Coefficient i.e. Koc value of test chemical was estimated using EPI suite KOCWIN Program (v2.00) as 13.4 L/kg (log Koc= 1.1271) by means of MCI method at 25°C. This log Koc value indicates that test chemical has negligible sorption to soil and therefore test chemical have a rapid migration potential to ground water.
Key value for chemical safety assessment
- Koc at 20 °C:
- 13.4
Additional information
Data for the test chemical and its read across substance were reviewed for the adsorption end point which are summarized as below:
In a prediction done using the KOCWIN Program of Estimation Programs Interface was used to predict the soil adsorption coefficient (Koc) of test chemical. The soil adsorption coefficient i.e Koc value of test chemical was estimated to be 13.4 L/kg (log Koc=1.1271) by means of MCI method (at 25ªC).
For the test chemical, adsorption coefficient (Koc) of test chemical was estimated to be 1.16.
On the basis of above results, test chemical was considered to have a negligible sorption to soil and sediment and therefore have rapid migration potential to ground water.
