Description of key information

Log Koc was calculated to 7.08 (MCI method). Optionally, log Koc was estimated to 8.00 using log Kow.

Key value for chemical safety assessment

Koc at 20 °C:
12 123 000

Additional information

The Koc of diisotridecyl adipate was estimated with the program US EPA EPI Suite (v 4.00), program component KOCWIN (MWC, 2010). Using a correlation based on molecular connectivity index, the log Koc was determined to be 7.0836 (Koc = 1.2123E07 L/kg). Using a correlation based on Kow, the log Koc was 8.0012 (Koc = 1.00277E08 L/kg) (MWC, 2010). The high Koc values indicate a distinct potential of diisotridecyl adipate to accumulate in soil and sediment.

The McCall classification scheme classifies the substances as immobile in soil (Koc>5000).
