Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this study the dermal LD50 was established to exceed 2000 mg/kg bw in male/female Wistar rat. Applicant assessment indicates, under the conditions of this study, and according to the GHS criteria, the LD50 cut-off value was considered to be greater than 5000 mg/kg body weight.
- Executive summary:
The study was performed according to OECD TG 402, EU Method B.3 Acute Toxicity (Dermal), US EPA OPPTS 870.1100 and Japanese JMAFF guidelines in accordance with GLP to assess the acute dermal toxicity of the test item in the Wistar strain rat. A group of ten animals (five males and five females) was given a single, 24 hour, occluded dermal application of the undiluted test item to intact skin at a dose level of 2000 mg/kg body weight. Clinical signs and body weight development were monitored during the study. All animals were subjected to gross necropsy. There was no mortality during the study. There were no signs of system toxicity or abnormalities on necropsy. Clinical signs and/or local effects consisted of chromodacryorrhoea in two females on Day 1. Whereas, focal erythema (Days 2 and 3) and scales (between Days 4-7) were observed on the treated skin-area of two males and one female. The body weight gain during the observation period was within the expected range. Under the conditions of this study, the dermal LD50 was established to exceed 2000 mg/kg bw in male/female Wistar rat. Applicant assessment indicates, under the conditions of this study, and according to the GHS criteria, the LD50 cut-off value was considered to be greater than 5000 mg/kg body weight.
