Description of key information

log Koc: 4.52 – 6.25 (KOCWIN v2.00)

Key value for chemical safety assessment

Additional information

No studies are available for 2,2-bis[[(1-oxopentyl) oxy]methyl]propane-1,3-diyl divalerate (CAS-No. 15834-04-5) on adsorption/desorption. Using KOCWIN v2.00, a log koc value of 4.52 (estimate from log Kow) and of 6.25 (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.
