Description of key information
Additional information
Conclusions for Decanoic acid, mixed esters with dipentaerythritol, octanoic acid and valeric acid (EC# 270-470-1)arebased on read-across from analogue substances of an existing category (pentaerythritol and dipentaerythritol esters), of which the members were notified under Directive 67/548/EEC (NONS) in 2003/2004 via the UK Competent Authority. The term 'read-across' for the substances other than the substance of interest means that these endpoints were already read-across in the existing category.
Based on the similar physic-chemical properties obtained for all members of the category in combination with the available experimental data for environmental endpoints, it can be expected that all substances would cause similar environmental toxicity,despite the variation of chain length and the presence of branched vs. linear fatty acid esters. With an average molecular weight of 640, the substance of interest, i.e. Decanoic acid, mixed esters with dipentaerythritol, octanoic acid and valeric acid (EC# 270-470-1) falls well within the average molecular weight range of the members of the category (637 – 1023).
At the slightly basic pH’s seen in aquatic systems, the hydrolysis of the dipentaerythrithol esters may be limited for steric reasons, i.e. the ester groups are expected to be well shielded by the aliphatic substituents and thus not be accessible for hydrolytic degradation. Therefore it is expected that the substances will be present mainly unsplit and that the toxicity of the intact moiety needs to be considered.
The ability of the dipentaerythrithol esters to reach the target sites in aquatic organisms will depend strongly on their solubility and their octanol-water partition coefficient. Solubility of the members of the category in aqueous media is in general low and the octanol-water partition coefficient is very high (EpiWin).
Therefore, bioaccumulation in aquatic organisms is not favoured.
Based on the above considerations, it can be concluded that the eco-toxicological properties for Decanoic acid, mixed esters with dipentaerythritol, octanoic acid and valeric acid (EC# 270-470-1) can be derived directly by read-across from known esters.
Acute toxicity to fish (LL50) is > 100 mg/l, i.e. >> water solubility.
Acute toxicity to aquatic invertebrates (Daphnia) (EL50) is > 100 mg/l, i.e. >> water solubility.
Acute toxicity to aquatic plants (Algae) (EL50) is > 47 mg/l, i.e. >> water solubility.
