Description of key information

Based on EPI prediction Level III Fugacity Model (EPI suite, 2016), the estimated half-life period of D & C Orange No. 5 (CAS no. 596 -03 -2) in soil was estimated to be 120 days (1440 hrs).Based on this half-life value of D & C Orange no. 5, it isconcluded 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
