Description of key information

For the test item Reaction product of adipic acid and sebacic acid and isotridecan-1 -ol is no study available. However, it is likely that the studies conducted on the component diisotridecyl adipate are valid for Reaction product of adipic acid and sebacic acid and isotridecan-1 -ol (please see justification for read-across). In an algal inhibition test with the component diisotridecyl adipate as test substance it can be concluded that the EL50 (24 -72 h) based on the growth rate is > 1000 mg/l nominal concentration and the NOEL based on the growth rate is >= 100 mg/l nominal concentration.

Additional information

For the test item Reaction product of adipic acid and sebacic acid and isotridecan-1 -ol is no study available. However, it is likely that the studies conducted on the component diisotridecyl adipate are valid for Reaction product of adipic acid and sebacic acid and isotridecan-1 -ol (please see justification for read-across).

Based on the result of the algae study it can be concluded that the EL50 (24 -72 h) of the component Diisotridecyl adipate based on the growth rate is > 1000 mg/l nominal concentration and the NOEL based on the growth rate is >= 100 mg/l nominal concentration (Häner/Panolin, 1998).

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