EC number: 946-959-7
CAS number: -
A stock solution of the test substance should be prepared in n-octanol pre-saturated with water. Because of a low solubility of the test substance in this medium, the stock solution was prepared in water pre-saturated with n-octanol.
This deviation has no effect on the determination of log Pow of the test substance.
The partition coefficient of the test substance, Acid Black 227, was determined.
For determination of partition coefficient was used the shake-flask method.
The test was performed according to the shake-flask method (OECD Test Guideline 107, Partition Coefficient (n-octanol/water): Shake Flask Method, Adopted 27 July 1995).
Partition coefficient (log P) of the test substance, Acid Black 227, determined by shake-flask method is:
log Pow = -1.13 ± 0.22 (pH 7.77, 23°C)
