Results and discussion

Partition coefficient
Key result
Type:
log Pow
Partition coefficient:
ca. -1.149
Temp.:
20 °C
pH:
ca. 4.976
Details on results:
It was estimated from the measured solubility data.

Partition coefficient (n-octanol/water) log P (o/w)
Result
log P (n-octanol) = log 1,118 = 0,041
log P (water) = log 15,52 = 1,190
log P(o/w) = 0,041-1,190 = - 1,149

Applicant's summary and conclusion

Conclusions:
Partition coefficient (n-octanol/water) log P (o/w) = - 1.49
Executive summary:

Partition coefficient (n-octanol/water) log P (o/w) = - 1.149
