Results and discussion

Partition coefficient
Type:
log Pow
Partition coefficient:
> 5

Any other information on results incl. tables

The solubility of the test substance in n-octanol was determined to be

> 7.6x10e5 mg/1 by means of visual observations. During NOTOX Project

157589, the water solubility of DEMB was determined to be < 7.6x10e-3 g/l

by means of visual observations. Hence, the partition coefficient Pow was

estimated to be > 1.0x10e5 (log Pow > 5)
