Description of key information

Log Kow = 3.41

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
25 °C

Additional information

The substance used for estimation of log Kow is the amide derivative of Basic Brown 1 acetate. EPIWEB 4.1 does not include in its applicability domain salt forms and it is not therefore possible to use it as to predict data for this kind of substances.

However, the amide derivative has a similar polarity and can represent a conservative case for Basic Brown 1 acetate. In fact the prediction for its water solubility is in the same range of Basic Brown 1 acetate (0.0008 mg/l vs 0.1 mg/l).

The expected log Kow for Basic Brown 1 acetate is therefore considered <= 3.41.
