Description of key information

Based on EPI prediction Level III Fugacity Model (EPI suite, 2016), the estimated half-life period of (Tris(5-amino-4-hydroxy-3-(phenylazo) naphthalene- 2,7-disulphonato(2-))dialuminium (CAS No. 68475 -50 -3) in soil was obtained to be 120 days (2880 hrs). Based on this half-life value of (Tris(5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7-disulphonato(2-))dialuminium , it is concluded that the chemical is not persistent in the soil environment.

Key value for chemical safety assessment

Half-life in soil:
120 d
at the temperature of:
25 °C
