- unchanged (no vehicle)
- Details on dermal exposure:
- TEST SITE
- Area of exposure: approximately 24 hours before the test, fur was clipped from the dorsal and ventral area of the trunk of the test. An area of about 6x5 cmq of the body dorsal surface was cleared for the application of the test article.
- % coverage: about 10% of the total body surface
- Type of wrap if used: the treated area was covered with the porous gauze dressing fixed to the skin with hypoallergenic non irritating tape. The test site was further covered in a suitable manner in order to ensure that the animals could not ingest the test substance.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): the residual test article was wiped off with water.
- Time after start of exposure: at the end of the exposure period, i.e. 24 h

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- In conclusion, the test article, when administered by dermal route to the rat, did not cause mortality or show appreciable toxic effects at the limit dose of 2000 mg/kg. The LD50 by dermal route was considered to be higher than 2000 mg/kg.
- Executive summary:
The purpose of the study was to evaluate the acute dermal toxicity of the test article. The test method was in accordance with EU method B.3 and OECD guideline 402 and in compliance with good laboratory practices (GLP).
Male and female Sprague Dawley Crl:CD(SD) BR rats (5 per sex and group) received a single dermal administration of the test article at the dosage of 2000 mg/kg. The test article was applied uniformly onto the cleared dorsal and ventral area of rat trunk (fur was clipped 24 hours previously). A porous gauze was fixed to the area and remained there for about 24 hours. The individual dosages were based on body weight taken just before treatment.
The day of treatment was considered as day 1 of the study. Animals were weighed twice before treatment (at randomization and on day 1 just before treatment) and on days 8 and 15. They were clinically observed for 14 days after the 24-hour exposure period. On day 16 all rats were killed (fasted overnight) by excision of the femoral arteries after intraperitoneal overdosage anaesthesia with 5% sodium pentobarbital; animals were then submitted to a thorough autopsy.
No animals died and no general or local clinical signs or body weight abnormalities were observed in any treated rat during the observation period. No macroscopic findings were evident at the final autopsy.
In conclusion, the test article, when administered by dermal route to the rat, did not cause mortality or show appreciable toxic effects at the limit dose of 2000 mg/kg. The LD50 by dermal route was considered to be higher than 2000 mg/kg.
