Adsorption / Desorption :

Soil Adsorption Coefficient i.e Log Koc value of α,α-bis[4-(dimethylamino)phenyl]-4-(phenylamino)naphthalene-1-methanol was estimated as 7.334 at 25 deg C by means of MCI method. This indicates that α,α-bis[4-(dimethylamino)phenyl]-4-(phenylamino)naphthalene-1-methanol has very Strong adsorption to the organic carbon fraction of the soil and have a negligible migration potential to groundwater.

Henry's Law constant :

Henry's Law states that at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. Henrys Law Constant of α,α-bis[4-(dimethylamino)phenyl]-4-(phenylamino)naphthalene-1-methanol which is a solid at 25 deg C is 0.00000000000000000628 atm m³/mol. Due to the IUCLID input limitation the value considered for chemical safety assessment is 0.000000001 Pa m3/mol at 25oC.
