Interpretation of results:
Toxicity Category IV
Remarks:
Migrated information H312 Criteria used for interpretation of results: EU
Conclusions:
• Experimental LD50 dermal data is found for constituent MXDA. It is classified in the GHS acute toxicity hazard Category 5.
• Toolbox read-across analysis was used for acute dermal toxicity assessment of 2-Propenenitrile, reaction products with 1,3-benzenedimethanamine constituents A, B, C, D and E. The performed read-across predictions were focused on the main chemical functionalities present in the target chemicals. Based on the worst case-scenario constituents A, B, and D are categorized in the Category 4 and constituents C and E are categorized as Category 5 according to the GHS classification.
• However, analysis of the structural analogues found in the literature classified constituents A to E in GHS Category 4.
• Based on the worst-case scenario read-across prediction and the applied additive formula for the acute dermal toxicity of UVCB 2-Propenenitrile, reaction products with 1,3-benzenedimethanamine is evaluated as 1492. 53 mg/kg. This value falls in GHS/CLP Category 4.
Executive summary:

2-Propenenitrile, reaction products with 1,3-benzenedimethanamineis evaluated as LD50: 1492. 53 mg/kg. CLP: Acut tox dermal category 4 H312
