Log Koc 2.38

Key value for chemical safety assessment

Additional information

No studies on adsorption are available for substances belonging to the category C7-C9 aliphatic hydrocarbon solvents. However, category members are not expected to sorb significantly to organic matter in soil, sediment, and wastewater solids based on calculated log Koc values, with Normal-Heptane having a log Koc of 2.38 (HSPA Consortium 2010). Values were calculated using KOCWIN v2.00, a subroutine of the computer program EPI Suite™, 2000.
