Key result
Type:
log Pow
Partition coefficient:
> 4.76 - < 8.31
Temp.:
25 °C
pH:
ca. 7
Conclusions:
The partition coefficient of the substance ranges from 4.76 to 8.31 at 25°C based on a QSAR driven by the EPI Suite v4.11/KOWWIN v1.64
Executive summary:

The octanol:water partition of benzene mono-C10-13-alkyl derivatives, distillation residues, sulfonated, sodium salts was estimated using the US EPA's computer program EPIWIN software v4.11/KOWWIN v1.68 (ATL, 2016). The estimated octanol:water partition (Log Kow) ranges 4.76 from to 8.31.

Description of key information

The octanol:water partition was calculated using the US EPA's computer program  EPIWIN v4.11/KOWWIN v1.68.
