Description of key information

In a reliable OECD 121 GLP compliant study Behenyl Bottoms were determined to have an extrapolated Log Koc of >6.61.

Key value for chemical safety assessment

Additional information

Behenyl Bottoms, characterized as C18-22, distillation residues (CAS No. 1160164-88-4) were assessed for its absorption/desorption potential by determining the Log Koc. In a reliable (Klimisch 1) GLP compliant study conducted according to OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)) the extrapolated Log Koc of Behenyl Bottoms was found to be> 6.61.
