Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of this study the median lethal dose (LD50) of the test item after dermal application was found to be greater than 2000 mg/kg bw in male and female rats.
- Executive summary:
In an acute dermal toxicity study (Limit Test), young adult Wistar rats (5 males and 5 females) were dermally exposed to a single dose of 2000 mg/kg bw of the test item. The clipped application site (dorsal and dorso-lateral parts of the trunk, comprising at least 10% of the total body surface) was covered by semi-occlusive dressing during the 24-hour exposure period. The animals were observed for 14 days.
No mortality occurred. Neither signs of systemic toxicity nor local skin effects were observed in any male animal. No signs of systemic toxicity were observed in the female animals.
Moderate to severe erythema (grade 3) and very slight edema was noted in three females on study day 14. The body weight of all male and three female animals increased within the normal range throughout the study period. The body weight in two female animals slightly decreased or stagnated during the first week, probably due to the bandage procedure, but increased within the normal range during the second week.
No macroscopic pathologic abnormalities were noted in the animals examined at the end of the study (5 males and 5 females).
Accordingly, the acute dermal median lethal dose (LD50) was determined to be higher than 2000 mg/kg bw.
