After evaluating, test article had not been judged to be corrosive, so test article did not perform preliminary test and directly applied on main test.
Main study:
Before the test, 15 cm x 10 cm area over the dorsal region o f each test animal was shaved. The shoulder skin examination did not have any injury and marked the positions of the test and control area.
Gauze about 2.5cm x 2.5cm was evenly loaded with 0.5g test article and wetted by physiological saline. The gauzes were applied on the upper left and lower right dorsal skin of test animals.
Gauze patch about 2.5cm x 2.5cm was fully loaded with 0.5mL control article. The gauzes were applied on the upper right and lower left dorsal skin of test animals.
The gauzes loaded test article or control article were closely contact with dorsal skin of test animal through tightened bandage. After 4 hours working, the gauzes were taken off. The test area and control area were cleaned with water.
After gauzes taken off, the irritation response of rabbit skin was evaluated at 1, 24, 48, and 72 hours. Any skin irritation response, including erythema and edema was graded and recorded according to the ‘Grading system for skin reaction”.

Applicant's summary and conclusion
- 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 SB33 was 0 and CR SB33 was categorized as non-irritant. Therefore, CR SB33 was not met a category based on GHS criteria.
- Executive summary:
This test using the procedures outlined in the SuperLab Study Plan for MZ6 -181200022 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 SB33 was calculated to be 0. On the basis of the test results given above and according to Evaluation table for single dermal irritation, the response of CR SB33 was categorized as non-irritant.
