Aquatic bioaccumulation

Decanoic acid, mixed esters with heptanoic acid, octanoic acid and trimethylolpropane has a potential to bioaccumulate due to its predicted high Kow value (>9.66); a value in excess of 4.5 is considered to indicate a potential for bioaccumulation, according to screening criteria for bioaccummulation in ECHA guidance (Chapter R.11 PBT Assessment). The likely reliability of the log Kow is, however, considered to diminish above a value of 6, as noted in Appendix R.11-1 Annex 1 of ECHA guidance on PBT Assessment. Substances with log Kow between 4.5 and 6 are considered likely to be highly accumulating; however no substantial bioconcentration is assumed for compounds having log Kow values greater than 6. For compounds having log Kow greater than 6, a gradual decrease of the BCF is observed and it has been hypothesised within the published literature that a high log Kow is more an effect of solubility than a tendency of the substance to be lipophilic. Based on QSAR modelling, the BCF value for the test substance is estimated to be 34.88 L/kg ww (geometric mean) indicating that it has a low potential for bioaccumulative.

Furthermore, the substance is likely to be readily metabolised to fatty acids and trimethylolpropane via enzymatic hydrolysis therefore is expected to have a low potential to bioaccumulate.

Terrestrial bioaccumulation

As states above, the substance is likely to be readily metabolised to fatty acids and trimethylolpropane via enzymatic hydrolysis therefore is expected to have a low potential to bioaccumulate.
