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.
[LogKoc: 1.519]
