Description of key information

From an algal inhibition test with diisotridecyl adipate as test substance it can be concluded that the ErL50 (24 -72 h) based on the growth rate is > 1000 mg/l nominal loading rate and the NOErL based on the growth rate is ≥ 100 mg/l nominal loading rate. 

Key value for chemical safety assessment

Additional information

Based on the result of the algae study it can be concluded that the ErL50 (24 -72 h) of diisotridecyl adipate based on the growth rate is > 1000 mg/l nominal loading rate and the NOErL based on the growth rate is ≥ 100 mg/l nominal loading rate (Häner/Panolin, 1998).

The effect levels are far above the limit of water solubility of diisotridecyl adipate.
