Description of key information
No reliable studies are available for C14 AO. Data are read across from C12-14 AO on the basis that this substance contains a significant amount of C14 AO and the remainder comprises an analogue substance with very similar chain length.
Two reliable studies are available for C12 -14 AO. In the key study, Pseudomonas putida were exposed to C12 -14 AO for 18 hours in a Bringmann-Kuehn test. The EC10, based on reduction in growth rate, was 24 mg AO/L.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 24 mg/L
Additional information
No reliable studies are available for C14 AO. Data are read across from C12-14 AO on the basis that this substance contains a significant amount of C14 AO and the remainder comprises an analogue substance with very similar chain length.
Two reliable studies are available for C12 -14 AO. In the key study,Pseudomonas putidawere exposed to nominal concentrations of 0, 50, 100, 600, 1000, 10000 or 100000 mg/L of C12 -14 AO for 18 hours in a Bringmann-Kuehn test [Kolvenbach M (1990)]. The EC10, based on reduction in growth rate, was 24 mg AO/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
