Applicant's summary and conclusion
- Conclusions:
- The repeated dose toxicity NOAEL (No observed adverse effect level) of 5-nitrosalicylic acid to rabbit by the dermal route was estimated at a dose concentration of 766.666 mg/kg bw/day.On the basis of this NOAEL value it is concluded that the test substance is not toxic to rabbit by the dermal
route. - Executive summary:
The repeated dose toxicity NOAEL (No observed adverse effect level) of 5-nitrosalicylic acid to rabbit by the dermal route was estimated at a dose concentration of 766.666 mg/kg bw/day.On the basis of this NOAEL value it is concluded that the test substance is not toxic to rabbit by the dermal route.
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).
