- Strain:
- Vienna White
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Gaukler, D-6050 Offenbach/Main, FRG
- Weight at study initiation: mean 3.21 kg
- Housing: 1 animal per cage, stainless steel with wire mesh walk floor; floor area: 40 cm x 51 cm; no bedding in cages, saw-dust in waste trays
- Diet: Kliba 341, 4 MM, Firma Klingentalmuehle AG, CH-4303 Kaiseraugst, Switzerland (about 130 g per animal per day)
- Water: about 250 mL tap water per animal per day
- Acclimation period: at least 8 days before the beginning of the study
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 20 - 24
- Humidity (%): 30 - 70
- Air: fully air-conditioned rooms
- Photoperiod (hrs dark / hrs light): 12/12
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- water
- Controls:
- other: untreated skin of the same animal
- Amount / concentration applied:
- VEHICLE
- Vehicle: 80% aqueous formulation (w/w).
- Justification choice of vehicle: Because of the natural moisture of the skin, distilled water is used to prepare the suspensions so that the test can be carried out under as physiological conditions as possible.
TEST MATERIAL
- The test patches (2.5 x 2.5 cm) were covered with an about 0.5 mm layer of the suspension (thus, about 0.5 g of thes uspension is applied). - Duration of treatment / exposure:
- 4 hours
- Observation period:
- 72 hours
- Number of animals:
- 3
- Details on study design:
- - Clipping of the fur: at least 15 hours before application
- Application site: upper third of the back or flanks
- Removal of the test substance at the end of the exposure period with Lutrol and Lutrol/water (1:1).
- Readings: 30 - 60 minutes after removal of the test patches and 24, 48 and 72 h after beginning of application.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information
- Conclusions:
- Under the conditions of the test, the substance is considered to be not irritating or corrosive to the skin.
- Executive summary:
The potential to cause acute dermal irritation or corrosion was assessed in a OECD 404 guideline study. The intact skin of three Vienna White rabbits was exposed by a single topical application of an amount of 0.5 g of the test substance for 4 hours using a patch of 2.5 cm x 2.5 cm covered with a semiocclusive dressing. After removal of the patch, the application area was washed off. The cutaneous reactions were assessed immediately after removal of the patch and approximately 24, 48, 72 hours after removal. No effects were observed. It was concluded that the test substance was not irritating to the skin.
