Description of key information

Toxicity to aquatic algae: NOEC - 108 mg/L

Key value for chemical safety assessment

EC10 or NOEC for freshwater algae:
108 mg/L

Additional information

Algal growth inhibition has been investigated in a 72 hour test according to OECD test methods on a structurally similar trimellitate, tri(2 -ethylhexyl)trimellitate (TOTM). Dissolution/dispersion agents were used to increase concentration of the substance in the test medium. The EC50 (72h) was determined to be >100 mg/L and the NOEC was 100 mg/L, the highest concentration examined.

Adjusting for differences in molecular weight between the tested substance and the registered substance, these values equate to an EC50 (72h) of >108 mg/L and a NOEC of 108 mg/L.
