Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the results of the study, the acute dermal LD50 of the test article is greater than 2,000 mg/kg body weight in male and female rats.
- Executive summary:
The acute dermal lethality potential of MTDID 665 was evaluated in male and female Wistar rats. The study was conducted according to OECD No. 402 (1987). The study was conducted in compliance with OECD GLP. MTDID 665 (liquid - dosed undiluted) was administered to 5 Wistar rats of each sex by a single dermal application at 2000 mg/kg body weight and held in place for 24 hours. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrafice (day 15). No mortality occurred. Chromodacryorrhoea was noted among animals on day 1. Scabs or scales were noted in the treated skin area of 2 females between day 7 and 15. The body weight gain during the observation period was within the range expected. No abnormalities were found at the macroscopic post mortem examination. The dermal LD50 value of MTDID 665 was established to exceed 2000 mg/kg. Based on these results, the material does not have to be classified and has no obligatory labeling requirement for dermal toxicity according to GHS.
