Description of key information

The adsorption coefficient (Koc) of the test material is > 4.27 x 10E5 (log10 Koc >5.63)

 

Calculations of adsorption/ desorption of renewable diesel have also been provided to support the read-across from renewable diesel to registration substance.

Key value for chemical safety assessment

Additional information

The adsorption coefficient (Koc) of the test material was determined in a GLP compliant laboratory according to OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)). A calibration curve was constructed from the retention time data of the deadtime and 13 reference standard solutions and adsorption coefficient of the test material was determined based on it.

The adsorption coefficient (Koc) of the test material is > 4.27 x 10E5 (log10 Koc >5.63)
