Description of key information
Both, IC50 and IC20 (3 h) of the test item FAT41029/A were greater than 1000 mg/l. No inhibition of bacteria growth was observed in this study.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
The bacteria toxicity test of FAT 41029/A was performed according to OECD 209 and 87/302/EEC, L 133, Part C under GLP compliance. Due to its physicochemical properties the test item was not completely soluble in the test medium. The reported results are related to the amount of the test item given into the test system. The test result showed the respiration rate of activated sludge microorganisms was not inhibited when exposed to the test article concentrations in the range from 25.6 to 1000 mg/l. The 3 h IC50 of reference item was 9.6 mg/l, with the 95 % confidence limits of 7.3 -12.5 mg/l. Thus, the IC50 (3 h) of the test item FAT41029/A was greater than 1000 mg/l.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
