Endpoint:
partition coefficient
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The study estlmated the octanol/water partition coefficient of benzal chloride using the software program KOWWIN. Hence, this study should be considered a Klimisch 2f study: accepted calculation method.
Justification for type of information:
QSAR prediction: migrated from IUCLID 5.6

Applicant's summary and conclusion

Conclusions:
The authors estimated an octanol/water partition coefficient of 2.97 log Pow for benzalchloride using the KOWWIN program (v1.67).
Executive summary:

The study estimates the logarithm of octanol/water partition coefficient (log Pow) of benzal chloride (CAS n° 98 -87 -3) to be 2.97 using the KOWWIN program v1.67 (estimation method described by Meylan and Howard).

The study is considered as reliable with restrictions since the study uses an accepted calculation method.
