Any other information on results incl. tables

The prediction was based on dataset comprised from the following descriptors: "Primary Irritation Index"
Estimation method: Taking average value from the 7 nearest neighbours
Domain logical expression:Result: In Domain

(("a" and "b" ) and ("c" and "d" ) )

Domain logical expression index: "a"

Similarity boundary:Target: C(=O)(O)c1cc(C(=O)OC)cc(N(=O)=O)c1
Threshold=50%,
Dice(Atom pairs)

Domain logical expression index: "b"

Similarity boundary:Target: C(=O)(O)c1cc(C(=O)OC)cc(N(=O)=O)c1
Threshold=60%,
Dice(Atom pairs)

Domain logical expression index: "c"

Parametric boundary:The target chemical should have a value of log Kow which is >= 0.951

Domain logical expression index: "d"

Parametric boundary:The target chemical should have a value of log Kow which is <= 2.07

Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The Primary irritation index for methyl 5-nitrohydrogen.isophthalate is found to be 0.914. Since the value of PII is in between below 0.99 so it can be concluded that is substnace is bearly irritating to skin.
