- Local signs: Before administration and daily from days 2 to 15
- Viability / mortality were checked together with clinical signs. However, it was recorded twice a day using the Pristima system.
- Body weight: On study days 1 (pre-administration), 8 and 15
- Necropsy of survivors performed: All animals were sacrificed at the end of the observation period (day 15), by intraperitoneal injection of sodium pentobarbital. The animals were then examined macroscopically.
Results and discussion
- Preliminary study:
- In the sighting study two males and two females were treated by dermal route on a single occasion at 2000 mg/kg. There was no mortality, clinical signs or local alterations in the administration area. Body weight was within the range commonly recorded for this strain and age. As no mortality was observed, this dose was administered in the Main Study.
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No deaths occurred during the study at the dosage level of 2000 mg/kg.
- Clinical signs:
- There were no clinical signs or local alterations in the administration site during the course of the study.
- Body weight:
- Body weight was within the range commonly recorded for this strain and age. However, there was a 0.1 and 1.2% body weight decrease in two females during the first week, which was recovered during the final week.
- Gross pathology:
- No macroscopic findings were recorded at necropsy.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- No mortality was recorded in the acute dermal toxicity test. The LD50 was determined to be higher than 2000 mg/kg bw when administered by dermal route to rats, and therefore assignment of hazard statement is unnecessary.
- Executive summary:
The acute dermal toxicity of the test substance was assessed according to OECD guideline 402 and GLP principles. In this study, initially, two males and two females Sprague Dawley (Sprague Dawley®SD®) rats were treated by dermal route on a single occasion at 2000 mg/kg under semi-occlusive conditions. After 24 hours the test substance was removed with distilled water. As no mortality was observed, this dose was administered in the main study. For the main study, five males and five females were treated on a single occasion at 2000 mg/kg. The observation period was 14 days. All animals were examined for clinical signs in the first 30 minutes after dermal application and 1, 2, 3 and 5 hours after on day 1 and once daily during test days 2-15. Administration area was also examined before administration and once daily from day 2 until the end of study. Body weights were recorded on day 1 (prior to administration) and on days 8 and 15. All animals were necropsied and examined Macroscopically. All animals from the main study survived until the end of the observation period. It was determined that body weight were within the range commonly recorded in rats of this strain and age. No clinical signs, local alterations (in administration area) and macroscopic findings were observed during the course of the study.
Since no mortality was recorded after administration of the tested substance at the dose of 2000 mg/kg, the LD50 was found to be higher than the above-mentioned dose when administered by dermal route to rats.
