Partition coefficient

Link to relevant study record(s)

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.

Description of key information
