Applicant's summary and conclusion
- Conclusions:
- Repeated dose toxicity LOEL (Lowest observed effect level) in 14 days study of l-Glutamic acid, N-coco acyl derivs., monosodium salts in rat by the inhalation route based on effect on body weight was found at a dose concentration of 23.965074539 mg/kg/day.
- Executive summary:
Repeated dose toxicity LOEL (Lowest observed effect level) in 14 days study of l-Glutamic acid, N-coco acyl derivs., monosodium salts in rat by the inhalation route based on effect on body weight was found at a dose concentration of 23.965074539 mg/kg/day.On the basis of this LOEL it is concluded that the test substance is not toxic to rat by oral route below the mentioned dose.
