Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- water
- Details on dermal exposure:
- The fur was removed from the dorsaI surfaces of the trunk over an area estimated to be at least 10% of the total body surface of each animal. An electric cllpper with suitable blade was used and care was taken to avoid any irritation or damage to the skin.
The next day (Day 1), the amount of supplied test substance to be administered, at a dose level of 2000 mg/kg body weight was calculated for each animal according to body weight. This was mixed to a paste with sterile water and spread evenly over the prepared skin of each animal. The mixing with water and volume of water used was not recorded due to oversight. The dosed site was then covered by a porous gauze dressing, held in place by encircling the trunk of the animal with an elastic adhesive bandage overlying aluminium foil. After a period of twenty four hours, the adhesive bandage and gauze dressings were removed. The treated skin was washed gently with warm water to remove residual test substance. - Duration of exposure:
- 24 hours
- Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 5
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Mortality/viability were measured throughout the study twice daily
- Body weights were measured at allocation of the study (Day -1), immediately prior to dosing (Day 1) and at weekly intervals thereafter (Days 8 and 15).
- Animals were observed for clinical signs immediately upon dosing, approximately two and four hours after dosing and daily thereafter for a total of fourteen days.
- Necropsy of survivors performed: AII animaIs were killed by carbon dioxide narcosis on terminatlon of the defined post-dose observation perlod. Animals were subjected to a gross examination for external abnormalities. The cranial, thoracic and abdominal cavities were opened to allow examination of their contents and larger organs were sectioned. Particular attention was paid to the treated site.

- Mortality:
- No mortality occured during the fourteen day observation period following dosing.
- Clinical signs:
- other: No clinical signs were observed during this post-dose observation period that could be attributed to an effect of the test substance. The only finding was hair loss from the ventral surfaces of one female animal, observed on day 15. Such hair loss may be

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The toxicity of the test substance was estimated to be greater than 2000 mg/kg bw
- Executive summary:
In a GLP compliant dermal toxicity study, performed according to OECD guideline 402, Sprague-Dawley rats (5/sex) were administered the test substance (2000 mg/kg bw). The test substance was dissolved in water, applied on the skin and covered with an occlusive dressing for 24 hours. The treated skin was washed after 24 hours and a 14-day observation period followed. No mortality was observed during this period. Also no clinical signs and significant changes in body weight were observed. Furthermore, no abnormalities were found on necropsy. Therefore, the toxicity of the test substance was estimated to be >2000 mg/kg bw.
