Description of key information

The soil adsorption coefficient (Koc) value of 2 Phenylpropionaldehyde is estimated to be 33.08 L/kg (log KOC =1.519),  indicating that it is has a 
low sorption to soil and sediment and therefore have moderate migration potential to groundwater.

Key value for chemical safety assessment

Koc at 20 °C:
33.08

Additional information

WoE study summary:

All predicted sources i.e EPI Suite,PBT profiler and Chemspider database indicate that the test substance 2 Phenylpropionaldehyde has a low sorption to soil and sediment and therefore have moderate migration potential to groundwater.

With following Koc values:

EPI SUITE - 33.08 (Log Koc=1.519)

PBT profiler -33 (Log KoC=1.518)

Chemspider -275.87 (log KOC =2.44)

Other weight of evidence study for read across from HSDB database indicate that the soil adsorption coefficient (Koc) value of 1-phenylethanol is found to be 37 L/kg in Fullerton soil (log KOC =1.568) and in Dormont soil type it would be 52 (log Koc=1.716) indicating that it is has a low sorption to soil and sediment and therefore have moderate migration potential to groundwater.
