Description of key information

Results from an aerobic respiration study, using an activated sludge inoculum, suggests that isodecyl benzoate would not produce effects to soil micro-organisms.

Key value for chemical safety assessment

Additional information

In accordance with REACH Chapter R.7C Endpoint Specific Guidance, specifically R.7.11.6.3 Testing Stategy (Table R.7.11-2), data to characterize toxicity to soil microorganisms is waived for the following reasons. Isodecyl benzoate is readily biodegradable, consequently it is considered to degrade rapidly in the environment and not persist. Isodecyl benzoate does not cause acute or chronic aquatic toxicity at its maximum water solubility, consequently it does not pose an acute or chronic aquatic hazard, and it is not possible to derive NOEC or PNEC values needed for quantitative risk assessment. However, it is possible to qualitatively conclude based on low solubility and available effects test data that isodecyl benzoate is not harmful to aquatic organisms. Data also show that isodecyl benzoate does not inhibit respiration in wastewater treatment microorganisms at levels above its water solubility. Therefore, based on these considerations, additional short and long-term toxicity testing for soil microorganisms is not needed.
