Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Charles River France, L’Arbresle Cedex, France
- Age at study initiation: between 12 and 24 weeks old
- Weight at study initiation: body weights were at least 1.5 kg
- Housing: labeled cages with perforated floors and shelters
- Diet (e.g. ad libitum): Pelleted diet for rabbits approximately 100 grams per day. Hay and wooden sticks were available during the study period.
- Water (e.g. ad libitum): Free access to tap water.
- Acclimation period: at least 5 days before start of treatment
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 18 to 24°C
- Humidity (%): 40 to 70%
- Air changes (per hr): at least 10 air changes/hour
- Photoperiod (hrs dark / hrs light): a 12-hour light/12-hour dark cycle
IN-LIFE DATES: From: To:
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- other: watery ethanol (50% v/v)
- Controls:
- no
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.5 grams of the test substance
VEHICLE
- Amount(s) applied (volume or weight with unit): 1 mL - Duration of treatment / exposure:
- 4 h
- Observation period:
- 72 hours after the removal of the dressings and test substance
- Number of animals:
- 3 males
- Details on study design:
- TEST SITE
- Area of exposure: 2x3 cm
- Type of wrap if used: The metalline patch was mounted on Micropore tape, which was wrapped around the abdomen and secured with Coban elastic bandage.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): the dressing was removed and the skin cleaned of residual test substance using tap water.
- Time after start of exposure: Four hours
OBSERVATION:
-Mortality/Viability: Twice daily.
-Toxicity: At least once daily.
-Body Weight: Day of treatment (prior to application) and after the final observation.
-Necropsy: No necropsy was performed according to protocol.
-Irritation: The skin reactions were assessed at approximately 1, 24, 48 and 72 hours after the removal of the dressings and test substance. The irritation scores and a description of all other (local) effects were recorded. Adjacent areas of the untreated skin of each animal served as controls.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Conclusions:
- Based on these results the test substance does not have to be classified and has no obligatory labelling requirement for skin irritation according to the:
- Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2011) (including all amendments);
- Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (including all amendments).
