- Koc
- Value:
- 75 dimensionless
- Remarks on result:
- other: Log Koc: 1.87
- Transformation products:
- no
- Validity criteria fulfilled:
- not specified
- Conclusions:
- Study was conducted to determine Adsorption coefficient (KOC) of test chemical. The Koc value of test chemical was estimated to be 75 (Log Koc: 1.87) calculated using a logKow and a regression derived equation.
- Executive summary:
Adsorption study was conducted for estimating the adsorption coefficient (Koc) value of test chemical. The adsorption coefficient (Koc) value was calculated using a logKow of 1.88 and a regression derived equation. The adsorption coefficient (Koc) value of test chemical was estimated to be 75 (Log Koc = 1.87). This Koc value indicates that the test chemical has low sorption to soil and sediment and therefore have moderate migration potential to ground water.

Description of key information
Adsorption study was conducted for estimating the adsorption coefficient (Koc) value of test chemical. The adsorption coefficient (Koc) value was calculated using a logKow of 1.88 and a regression derived equation. The adsorption coefficient (Koc) value of test chemical was estimated to be 75 (Log Koc = 1.87). This Koc value indicates that the test chemical has low sorption to soil and sediment and therefore have moderate migration potential to ground water.
Key value for chemical safety assessment
- Koc at 20 °C:
- 75
