Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Ecotoxicol. Environ.Saf. 11, 251-260 (1986)
Type of method:
shake-flask method to: flask method
Remarks:
similar to shake-flask method (Slow-stirring method ( Brooke et al. (1986) )
Partition coefficient type:
octanol-water
Type:
log Pow
Partition coefficient:
0.45
Temp.:
25 °C
pH:
>= 6.8 - <= 7.1
Details on results:
Temperature was stated as "room temperature" = 25°C (taken from IUCLID 4).
log P = 0.45 +/- 0.08
Conclusions:
The octanol-water partition coefficient log Pow has been experimentially determined at 'room temperature' as 0.45.

Description of key information

The octanol-water partition coefficient log Pow has been experimentially determined at 'room temperature' as 0.45.

Key value for chemical safety assessment

Log Kow (Log Pow):
0.45
at the temperature of:
20 °C

Additional information

It is not clear from the literature reference whether the 'room temperature' was 20°C or 25°C.
