Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
Edema and erythema scores were 0 for all animals. Therefore, the test item is not classified for skin irritation.
Executive summary:

The skin irritancy potential of the test item was assessed using 500 mg of the test item. The study was conducted according to a standard guideline using Japanese white rabbits. The mean and max edema and erythema scores were 0 for all animals. No other effects were observed. Therefore, the test item is not classified for skin irritation.

The study is a GLP compliant, guideline study and is acceptable with restrictions for evaluation of this endpoint.
