Description of key information

The range of partition coefficients (log Pow) at neutral pH and 25 °C for the major fractions within IOA is 4.5-4.7 using an HPLC method according to OECD TG117.

Key value for chemical safety assessment

Additional information

The partition coefficient (log Pow) of IOA was assessed using an HPLC method at 25 °C and neutral pH. The nine reported peaks had log Pow values ranging from 4.0 to 5.0. The major peaks (those contributing ≥ 5% of total peak area) comprised 92.7% of total peak area. The range of partition coefficients for the major fractions within the IOA is 4.5-4.7.
