Any other information on results incl. tables






The prediction was based on dataset comprised from the following descriptors: "Primary Irritation Index"
Estimation method: Takes average value from the 6 nearest neighbours
Domain  logical expression:Result: In Domain

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

Domain logical expression index: "a"

Referential boundary: The target chemical should be classified as Aromatic amines by Skin irritation/corrosion Inclusion rules by BfR

Domain logical expression index: "b"

Similarity boundary:Target: c1(N)cc(N{+}(.Cl{-})=C(N)O)ccc1
Threshold=30%,
Dice(Atom centered fragments)

Domain logical expression index: "c"

Parametric boundary:The target chemical should have a value of logP Multicase which is >= -2.69

Domain logical expression index: "d"

Parametric boundary:The target chemical should have a value of logP Multicase which is <= 2.53

Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The primary irritation index on rabbit for (3-aminophenyl)uronium chloride is estimated to be 1.91. Based on this value, it can be estimated that(3-aminophenyl)uronium chloride exhibits slight irritation potential to rabbit skin. However, the PDII score is not considered high enough for classification of the chemical as a skin irritant. Thus, the chemical (3-aminophenyl)uronium chloride is not considered to be a skin irritant.
Executive summary:

The primary irritation index on rabbit for (3-aminophenyl)uronium chloride is estimated to be 1.91. Based on this value, it can be estimated that(3-aminophenyl)uronium chloride exhibits slight irritation potential to rabbit skin. However, the PDII score is not considered high enough for classification of the chemical as a skin irritant. Thus, the chemical (3-aminophenyl)uronium chloride is not considered to be a skin irritant.
