The estimated logKOW was 14.85 (C12) and 16.32 (C13).

The BCFBAF version 3.00 programme of the EPI Suite software (EPIWEB 4.0) was used to predict either a log BCF of 0.5 (BCF of 3.16 L/kg) based on a regression estimate or a log BAF of - 0.05 (BAF of 0.893 L/kg) based on the Arnot-Gobas upper trophic model both using the smiles code because the log POW was > 8. Based on the expected kinetic behaviour in the body substantial amounts of 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, tris(C12 -13 branched-alkyl) esters will not accumulate in the body, because it will be hydrolysed, absorbed and efficiently metabolised into water soluble metabolites, which is supported by the molecular structure of 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, tris(C12 -C13 -branched alkyl) esters. Therefore the test item has no potential for bioaccumulation. The reliability of modelled log KoW values > 10 is not known. The aquatic BCF of a substance is probably lower than 2000 if the calculated log Kow is higher than 10.
