Interpretation of results:

GHS criteria not met

Conclusions:

According to OECD 404 test method and Evaluation table for single dermal irritation, the PII for Everlan SL65 was 0 and Everlan SL65 was categorized as non-irritant. Therefore, Everlan SL65 was not met a category based on GHS criteria.

Executive summary:

This test using the procedures outlined in the SuperLab Study Plan for M62-151100101001EN 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 Everlan SL65 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 Everlan SL65 was categorized as non-irritant.

Conclusions:

According to OECD 405 test method, Everlan SL65 did not show that positive irritant to the eye. Therefore, Everlan SL65 was not met a category based on GHS criteria.

Executive summary:

This test using the procedures outlined in the SuperLab Study Plan for M62-151100102001EN which is based on the SOP for the OECD 405 (SOPP-306) and OECD 405 (OECD, 2012). There were no test article effects on body weight. Everlan SL65 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. Cornea and iris with score 0 during all study period. Irritant reaction that caused by test article was disappeared within 48 hours after dosing. On the basis of the test results given above, the response of the test article did not cause positive irritating to the eye.
