Description of key information

The PBT Profiler & EPI Suite has estimated that Eicosanoic acid is expected to be found predominantly in soil and its persistence estimate is based on its availability in this medium. Its half-life in soil, 30 days (720 hrs).,does not exceeds the threshold of 120 days as per Annex XIII of REACH.Therefore, Eicosanoic acid is estimated to be not persistent in the soil environment.

Key value for chemical safety assessment

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