Description of key information

EL50/EL10 (72h) > 100 mg/L (nominal loading rate) for Pseudokirchneriella subcapitata (OECD 201)

Key value for chemical safety assessment

Additional information

One study investigating the toxicity of Reaction mass of bis(2-propylheptyl) hexanedioate and O6-[2,2-bis[[6-oxo-6- (2-propylheptoxy)hexanoyl]oxymethyl]butyl] O1-(2-propylheptyl) hexanedioate to algae is available. The study was performed according to GLP and OECD guideline 201 using Pseudokirchneriella subcapitata as test organism (BASF 2016). A 100 mg/L loading rate was tested as limit test. All validity criteria are fulfilled. No growth rate inhibition was observed in the treatment compared to the control. Thus, the 72h-EL50 and EL10 value is determined to be > 100 mg/L based on nominal concentration.
