Available information:The adsorption coefficient for 1-Phenylethylbenzene was determined according to OECD Guideline 121 to be 4316 and the Log Koc was determined to be 3.64.Results log Koc diphenylmethane category calculated with EPI (Estimation Programs Interface) Suite™:1,1-DPE: 4.185Benzyltoluene: 4.167Phenyl-tolyl-ethane: 4.51SAS-296: 4.60SAS-305: 4.87
The adsorption coefficient for 1-Phenylethylbenzene was determined
according to OECD Guideline 121 to be 4316 and the Log Koc was
determined to be 3.64.
Koc values for members of the diphenylmethane category were also
calculated by a reliable QSAR model.
1,1 -DPE is a slightly water soluble,
non-polar organic substance.
As a very hydrophobic substance,
supported by its measured Kow of 4.48, it is expected that 1,1 -DPE
would strongly adsorb to organic matter in soil to an appreciable extent.
This is conﬁrmed by the measured log
Koc value of 3.64.
Calculated values for adsorption coefficient
log Koc of the other members of the diphenylmethane category range from
4.2 to 4.9 the fact of which again clearly indicates the very close
similarity of all of its members.
For risk assessment purposes the measured
log Koc value of 3.64 is used.. No further testing is required.
For detailed read across rationale and
justification see section 13, Read across document.
