Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met

- No skin reaction at the treatment site was observed at 24, 48 and 72 hours after removal of test item using draize method. According to the OECD guideline the LD 50 cut-off is greater 2000 mg/kg bw.
- Executive summary:
The objective of this study was to assess the toxic potential of the test item Dodicor V 5654 when applied by dermal route to female Sprague Dawley rats at one or more defined dose levels according to OECD Guideline 402.
The study was performed in two phases i.e. range finding study and main study. Range finding study was performed with three female rats (one rat per each dose, i.e. 200, 1000 and 2000 mg/kg bw). Main study was performed with two female rats at a dose of 2000 mg/kg bw. The contact period of test item was 24 hours followed by a 14-day observation period.
All the animals were observed for clinical signs of toxicity and mortality at 20 to 30 mins, 1 hr (±10 mins), 2 hrs (±10 mins), 4 hrs (±10 mins) and 6 hrs (±10 mins) post dosing on Day 1 and thereafter once daily for clinical signs of toxicity and twice daily for mortality during the 14 days observation period. Individual animal body weight was recorded at receipt, on day 1 before test item application, on day 8 and 15 during the experimental period.
No mortality and clinical signs were noted. No treatment related changes in body weight and percent change in body weight with respect to day 1 were noted. Normal increase in body weights were noted during the observation period. No treatment related gross pathological changes were noted in any of the range finding study and main study animals during necropsy. No skin reaction at the treatment site was observed at 24, 48 and 72 hours after removal of test item using draize method.
