EC number: 225-590-9
CAS number: 4948-15-6
Estimation of log Pow:
Pow= C(n-octanol) / C(water)= 1.9 µg/L / 1.4 µg/L =
log Pow= 0.13
Estimated based on solubility ratio:
log Pow= 0.13 at 23°C
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.
