Description of key information

Soil Adsorption Coefficient i.e Koc value of piperazine adipate was estimated as 10 L/kg by means of MCI method. This Koc value when converted at 20 degC is equivalent to 27.032.

Key value for chemical safety assessment

Koc at 20 °C:
8

Additional information

Soil Adsorption Coefficient i.e Koc value of piperazine adipate was estimated as 10 L/kg by means of MCI method. This indicates that piperazine adipate will have low tendency of sorption to soil and sediment and therefore have moderate migration potential to groundwater.This Koc value when converted at 20 degC is equivalent to 8.

The supporting study shows value different from the key study which could be due to the difference in the estimation conditions.However, for the purpose of the dossier as well as for the chemical safety report the experimental value will be considered.
