Description of key information

Adsorption of Reaction mass of bis(2-propylheptyl) hexanedioate and O6-[2,2-bis[[6-oxo-6-(2-propylheptoxy)hexanoyl]oxymethyl]butyl] O1-(2-propylheptyl) hexanedioate to solid soil and sediment is expected.

Key value for chemical safety assessment

Additional information

No studies investigating the adsorption/desorption behaviour of Reaction mass of bis(2-propylheptyl) hexanedioate and O6-[2,2-bis[[6-oxo-6-(2-propylheptoxy)hexanoyl]oxymethyl]butyl] O1-(2-propylheptyl) hexanedioate are available. Using KOCWIN Program (v2.00), log Koc values of 5.59 and 17.88 were calculated for the main constituents based on the molecular conductivity index (MCI). The result of the QSAR calculation for DPHA (5.59) is considered appropriate as the substance is within the applicability domain of the QSAR model. Based on this information adsorption of Reaction mass of bis(2-propylheptyl) hexanedioate and O6-[2,2-bis[[6-oxo-6-(2-propylheptoxy)hexanoyl]oxymethyl]butyl] O1-(2-propylheptyl) hexanedioate to solid soil and sediment is expected.
