Description of key information

Short-term toxicity to Daphnia: EC50 - >100 mg/L; NOEC - 100 mg/L

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
100 mg/L

Additional information

Acute immobilisation in Daphnia has been investigated in a 48 hour test according to OECD test methods. Dissolution/dispersion agents were used to increase concentration of the substance in the test medium. The EC50 (48h) was determined to be >100 mg/L and the NOEC was 100 mg/L, the highest concentration investigated.

Tests with a structural analogue of the registered substance, a trimellitate ester with mixed C8 -C10 side chains, showed no toxicity when tested at, or above, the limits of water solubility.
