Any other information on results incl. tables

The prediction was based on dataset comprised from the following descriptors: NOAEL
Estimation method: Takes average value from the 5 nearest neighbours
Domain  logical expression:Result: In Domain

("a" and ("b" and "c" )  )

Domain logical expression index: "a"

Referential boundary: The target chemical should be classified as Group 14 - Carbon C AND Group 15 - Nitrogen N AND Group 16 - Oxygen O by Chemical elements

Domain logical expression index: "b"

Parametric boundary:The target chemical should have a value of log Kow which is >= -10.1

Domain logical expression index: "c"

Parametric boundary:The target chemical should have a value of log Kow which is <= 2.69

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.
