Description of key information

The potential for bioaccumulation in aquatic organisms of 2,2-bis[[(1-oxopentyl) oxy]methyl]propane-1,3-diyl divalerate (CAS-No. 15834-04-5) is assumed to be low.

Key value for chemical safety assessment

Additional information

A BCF was calculated to be 550 L/kg wet weight (BCFBAF v3.00, regression based estimate) which indicates that accumulation in organisms is possible.

However, as polyol esters are metabolised in fatty acids and polyol alcohols via enzymatic hydrolysis (HPV Polyol esters category of the aliphatic esters chemicals, American Chemistry Council, 2004), polyol esters are expected to have a low potential to bioaccumulate.
