Partition coefficient:
0.484
Remarks on result:
other: no additional details mentioned
Conclusions:
The estimated log Pow of Aluminum, tris[5-amino-4-hydroxy-3-(phenylazo)-2,7-naphthalenedisulfonato(2-)]di- was 0.4845
Executive summary:

KOWWIN v 1.68 of EPISUITE was used to estimate the octanol water partition coefficient of the test chemical.

The estimated log Pow of Aluminum, tris[5-amino-4-hydroxy-3-(phenylazo)-2,7-naphthalenedisulfonato(2-)]di- was 0.4845.

Based on this value, it can be concluded that Aluminum, tris[5-amino-4-hydroxy-3-(phenylazo)-2,7-naphthalenedisulfonato(2-)]di- is hydrophillic in nature
