Description of key information
C12-18 AO and C12-18 Ao exhibit similar toxicity to Pseudomonas putida. The value of 24 mg AO/L from a study with C12-14 AO is used for the chemical safety assessment.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 24 mg/L
Additional information
One reliable study is available for C12 -18 AO. In this study, Pseudomonas putida were exposed to nominal concentrations of 0, 50, 100, 1000, 10000 or 100000 mg/L of C12 -18 AO for 18 hours in a Bringmann-Kohn test [Kolvenbach M (1990)]. The EC10, based on reduction in growth rate, was 29.8 mg/L. In a similarly performed study using C12 -14 AO, the EC10 was 24 mg AO/L. This study is considered as the key study as the result is protective of C12 -18 AO.
