Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Log Koc > 5.63 at 40 °C
The substance has a high adsorption potential to soil and sediment.

Key value for chemical safety assessment

Additional information

The adsorption/desorption potential of Dipentaerythrol ester of nC5/iC9 acids was analysed in a HPLC screening study according to GLP and "OECD draft document (1997): Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using HPLC" (Lumsden, 2000). The test substance was analysed for its elution behaviour by comparison to 11 reference substances at a HPLC column temperature of 40 °C. The retention time of the test substance exceeded the range of the calibration curve and therefore, the log Koc is not given as distinct value but stated to be > 5.63.
