Description of key information

Conclusions on the acute aquatic invertebrates toxicity of Decanoic acid, mixed esters with dipentaerythritol, octanoic acid and valeric acid (EC# 270-470 -1) (Hatcol 1106) are based on read-across from analogue substances of an existing category. Acute toxicity to aquatic invertebrates (Daphnia) (EL50) is >100 mg/l, i.e. >> water solubility.
