Interpretation of results:
GHS criteria not met
Conclusions:
According to OECD 404 test method and Evaluation table for single dermal irritation, the PII for CR SB87 was 0 and CR SB87 was categorized as non-irritant. Therefore, CR SB87 was not met a category based on GHS criteria.
Executive summary:

This test using the procedures outlined in the SuperLab Study Plan for M62-151100117001EN which is based on the SOP for the OECD 404 (SOPP-305) and OECD 404 (OECD, 2015). The sites were grades for erythema and edema at 1, 24, 48 and 72 hours after the patches removal. No clinical signs of toxicity were found. Body weight changes were within the normal range in all animals. All animals was no formation of erythema, eschar or edema on the test area within 72 hours after patch removal. The Primary Irritation Index for CR SB87 was calculated to be 0. On the basis of the test results given above and according toEvaluation table for single dermal irritation, the response of CR SB87 was categorized as non-irritant.

Conclusions:
According to OECD 405 test method, CR SB87 showed that weak irritant to the eye. Therefore, CR SB87 was not met a category based on GHS criteria.
Executive summary:

This test using the procedures outlined in the SuperLab Study Plan for M62-151100126001EN which is based on the SOP for the OECD 405 (SOPP-306) and OECD 405 (OECD, 2012). CR SB87 was given by a single ocular application at 0.1 g amount to NZW female rabbits and followed by ocular examination within 72 hours and a 4 days clinical observation period. There were no test article effects on body weight. Reversible conjunctival chemosis and discharge was observed within 72 hours after test article application. On the basis of the test results given above, the response of the test article was weak irritant to the eye.

Additional information

Justification for classification or non-classification

Skin irritation

The sites were grades for erythema and edema at 1, 24, 48 and 72 hours after the patches removal.No clinical signs of toxicity were found. Body weight changes were within the normal range in all animals. All animals was no formation of erythema, eschar or edema on the test area within 72 hours after patch removal. The Primary Irritation Index for CR SB87 was calculated to be 0. On the basis of the test results given above and according toEvaluation table for single dermal irritation, the response of CR SB87 was categorized as non-irritant.

 

Eye irritation

CR SB87 was given by a single ocular application at 0.1 g amount toNZW female rabbits and followed by ocular examination within 72 hours and a 4 days clinical observation period. There were no test article effects on body weight. Reversible conjunctivalchemosisanddischargewas observed within 72 hours after test article application.On the basis of the test results given above, the response of the test article was not any irritant to the eye.
