Endpoint summary
Administrative data
Description of key information
An OECD 422 combined repeated dose study with reproductive and developmental toxicity screening was conducted on KGA to determine the subchronic toxicity to rats. The resultant NOAEL was 1000 mg/kg bw/day.
Key value for chemical safety assessment
Repeated dose toxicity: via oral route - systemic effects
Endpoint conclusion
- Dose descriptor:
- NOAEL
- 1 000 mg/kg bw/day
- Study duration:
- subchronic
- Species:
- rat
Additional information
An OECD 422 combined repeated dose study with reproductive and developmental toxicity screening was conducted on KGA to determine the subchronic toxicity to rats. Groups of rats were exposed by oral gavage to doses of 0, 500, 1000 and 2000 mg/kg bw/day of KGA Greens. Males were exposed for 28 days and females were exposed up through lactation day 4 or 53 days, after which surviving rats were sacrificed and necropsied. Observations of mortality and a suite of other examinations were conducted. Results show sporadic effects on various endpoints in the 2000 mg/kg bw/day high dose. At this 2000 mg/kg bw/day level the test substance appeared to be so irritating or distasteful that the animals tended to struggle and/or resist dosing, which in turn led to deaths likely caused by aspiration of gavaged material. No significant dose-related effects were observed in the 500 and 1000 mg/kg bw/day doses. The NOAEL was determined to be 1000 mg/kg bw/day.
Justification for classification or non-classification
Due to the lack of significant effects at 1000 mg/kg bw/day, KGA and KGA Greens are not classified.
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).
