Reference
Endpoint:
partition coefficient
Type of information:
experimental study
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Remarks:
OECD SIAP is a peer-reviewed source, therefore considered reliable. Restrictions applies as no details are available.
Principles of method if other than guideline:
Measured octanol-water partition coefficient. No other data.
Partition coefficient type:
octanol-water
Key result
Type:
log Pow
Partition coefficient:
2.83
Temp.:
20 °C
pH:
ca. 0 - ca. 14

Temperature and pH are not specified. Measurement is expected to be performed at ambient temperature (ca 20-25°C). No pH dependency is anticipated, as no ionisable feature is present in the chemical structure.

Conclusions:
The constituent has LOW potential for bioaccumulation, according to CLP classification criteria for aquatic chronic toxicity (log Kow <4).
Executive summary:

The OECD SIAP provides some physico-chemical parameters within the framework of the human health and environmental assessment.

For partition coefficient, a measured value (logKow) of 2.83 is cited.
