Interpretation of results:
Category 2 (irritant) based on GHS criteria
Conclusions:
The registration substance was investigated for its skin irritaiton property according to OECD 404. It was found to be irritating to skin.
Executive summary:

The registration substance was investigated for its skin irritaiton property according to OECD 404.

Among the three rabbits treated, two rabbits exhibited erythema of mean score of 2.3 for 24,48, and 72 hours reading and exhibited discoloration, dryness and scaling at reading time 7 and 14 day. The registration substance was found to be irritating to skin.

Interpretation of results:
GHS criteria not met
Conclusions:
The registration substance is not irritating according to the results obtained in the OECD 405 study.
Executive summary:

The registration substance was investigated for its eye irritation property according to the OECD 405. Schwelling and redening of conjunctivae was observed only at reading time of 24 hours. No classification is warranted.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

Additional information

Justification for classification or non-classification

The registration substance was investigated for its skin irritaiton property according to OECD 404. It was found to be irritating to skin.

The registration substance was investigated for its eye irritaiton property according to OECD 405. It was found to be not irritating to eye.

Based on GHS criteria, it should be classified as skin irritant, Category 2.
