- TEST ANIMALS
- Source: Charles River (UK) Ltd, Margate, Kent, UK.
- Age at study initiation: eight to twelve weeks of age
- Weight at study initiation: At least 200g. The weight variation did not exceed ± 20% of the mean weight for each sex.

- Diet (e.g. ad libitum): free access to certified rat and mouse diet
- Water (e.g. ad libitum): free access to mains drinking water
- Acclimation period: at least five days
- Other: The animals were provided with environmental enrichment items which were considered not to contain any contaminant of a level that might have affected the purpose or integrity of the study.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19 to 25 °C
- Humidity (%):30 to 70 %
- Air changes (per hr): at least fifteen changes per hour
- Photoperiod (hrs dark / hrs light): twelve hours continuous light (06:00 to 18:00) and twelve hours darkness.
IN-LIFE DATES: From: 31 March 2004 To: 14 April 2004.
Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- arachis oil
- Details on dermal exposure:
- TEST SITE
- Area of exposure: On the day before treatment the back and flanks of each animal were clipped free of hair. Test material was spread evenly over the area.
- % coverage: 10 % of body surface
- Type of wrap if used: a piece surgical gauze placed over the treatment area and semi-occluded with a piece of self-adhesive bandage
REMOVAL OF TEST SUBSTANCE
After the 24-hour contact period the bandage was carefully removed and the treated skin and surrounding hair wiped with cotton wool moistened with arachis oil BP to remove any residual test material.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute dermal median lethal dose (LD50) of the test material in the Sprague-Dawley CD strain rat was found to be greater than 2000 mg/kg bodyweight.
- Executive summary:
The study was performed to assess the acute dermal toxicity of the test material in the Sprague-Dawley CD strain rat. Five male and five female rats were given a single dermal application of the test material at 2000 mg/kg bodyweight. The test was conducted in accordance with the OECD 402 and EU Method B.3 guidelines. The study was performed to GLP standard in a certified laboratory.
Under the conditions of the study the acute dermal median lethal dose (LD50) of the test material in the Sprague-Dawley CD strain rat was found to be greater than 2000 mg/kg bodyweight.
