Administrative data

Endpoint:
partition coefficient
Type of information:
other: handbook data
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The data is provided by well-know and widely accepted reference books, some being also mentioned in table R.7.1.-2 of chapter R 7.1.1.2 of the Guidance on information requirements and chemical safety assessment. As such the data is considered as useful in a weight of evidence approach.
