Applicant's summary and conclusion

Interpretation of results:
practically nontoxic
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The LD50 value as predicted by the QSAR model was found to be 2230 mg/Kg bw of Rat by the oral route. This value suggests that sodium 4-aminonaphthalene-1-sulphonate shall not exhibit acute toxicity by the oral route within this concentration range
Executive summary:

The LD50 value as predicted by the QSAR model was found to be 2230 mg/Kg bw of Rat by the oral route. This value suggests that sodium 4-aminonaphthalene-1-sulphonate shall not exhibit acute toxicity by the oral route within this concentration range
