Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 4.52 – 11.47 (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

No studies are available for pentaerythritol tetraesters of n-decanoic, n-heptanoic, n-octanoic and n-valeric acids (CAS-No. 68424-31-7) on adsorption/desorption. Using KOCWIN v2.00 for the main components, log Koc values of 4.52 – 9.95 (estimate from log Kow) as well as 6.25 – 11.47 (estimate with MCI method) was calculated, indicating a high adsorption potential of the test substance. This result is supported by a read-across, on Ester reaction products of fatty acid, C5-10, pentaerythritol and dipentaerythritol, where a log Koc of 4 - 7 was established in a guideline study according to OECD 121 under GLP conditions.
