Results
1) General conditions and body weights
No abnormal findings were observed in general conditions of all three rabbits except the skin reactions during the observation period.
The body weights on 0 (the day of application), 3 (72 hours) and 14 days after application of the test substance are shown in Table 1. The body weights were increased smoothly during the observation period.
2) Skin reactions:
The scores of skin reactions and photos at the applied sites of the test substance in each rabbit during the observation period are shown in Tables 2 to 5 and Photos 1 to 4, respectively. (1) The application site No. 1: VEEA (intact skin) (Table 2, Photo 1)
VEEA, loaded on the cloth disc of adhesive plaster for patch test, was applied to the intact and abraded skin of three rabbits by closed patch for 4 hours and the primary skin irritation such as erythema and edema was still observed at 72 hours after application. Nothing was loaded on the cloth disc of adhesive plaster as control. Since the skin irritation was still observed at 72 hours after application of the test substance, the observation was continued for 14 days after application (until the skin irritation disappeared).
No abnormal changes in general conditions and body weight gains were found in all three animals through the observation period, By closed patch for 4 hours, the application of VEEA to the intact skin caused very slight erythema and edema in all three animals at 4 hours after application, but these irritant effects disappeared at 24 hours. On the other hand, the application of VEEA to the abraded skin produced slight to moderate erythema and edema in all animals at 4 hours after application, but these irritant effects were reduced with time. These adverse effects disappeared in two animals on 5 days after application and in the remaining one till 14 days. The application of adhesive plaster only as control to the intact skin caused no skin irritation in all three animals. On the other hand, the application of adhesive plaster only to the abraded skin produced very slight erythema in all animals at 4 hours after application. These signs were reduced with time, and disappeared in two animals at 72 hours after application and in the remaining one till 5 days. No edema was observed in all animals through the observation period. The primary irritation index (P.I,I.) was 2,00 for VEEA and 0.39 for adhesive plaster only as control. From these results, according to the criteria of Draize, VEEA was considered to be mildly irritating for rabbit skin under our experimental conditions.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The skin irritation has been determined as not irritating to the skin based on the OECD 404 study.
- Executive summary:
Skin Irritation:
VEEA, loaded on the cloth disc of adhesive plaster for patch test, was applied to the intact and abraded skin of three rabbits by closed patch for 4 hours. Nothing was loaded on the cloth disc as control. The application of the test substance to the intact skin caused very slight erythema and edema in all three animals after 4 hours, but these irritant effects disappeared till 24 hours. On the other hand, the application of the test substance to the abraded skin produced slight to moderate erythema and edema in all animals after 4 hours. These adverse effects were reduced with time, but remained still after 72 hours. Therefore, the observation was continued for 14 days (until the skin irritation disappeared). The skin irritation disappeared in two animals on 5 days after application and in the remaining one till 14 days. There were no abnormal findings in general condition and body weight gain in all animals during the observation period. The primary irritation index (P. I.I) was 2.00 for VEEA and 0.39 for control. According to the criteria by Draize, VEEA was evaluated to be mildly irritating for rabbit skin under our experimental conditions.
