at the temperature of:
23 °C

Additional information

The partition coefficient was estimated based on the individual solubilities.

The determination of solubilities in water and in n-octanol was carried out by flask method according to OECD Guideline 105 and also by the ETAD method. This standard method was developed by intensive cooperation with the ETAD (Ecological and Toxicological Association of Dyesand Organic Pigments Manufacturers) and is regarded as acceptable for pigments.

The study based on ETAD method had been chosen as key study since the test substance was purified.
