Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- Species: Albino rabbit, New Zealand White, (SPF-Quality). Recognized by international guidelines as the recommended test system (e.g. EC, OECD)
Source: Charles River France, L’ArbresleCedex, France
Number of animals: 3 Males.
Age and body weight: At start of dosing, the animals were between 12 and 24 weeks old and body weights were at least 1.5 kg.
Identification: Earmark.
Health inspection: At least prior to dosing. It was ensured that the animals were healthy and that the skin to be treated was intact and free from any abnormality.
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- water
- Amount / concentration applied:
- Each animal was treated by dermal application of 0.5 grams of the test item. The test item was moistened with 0.5 mL of the vehicle
- Duration of treatment / exposure:
- Each animal was treated by dermal application of 0.5 grams of the test item to the healthy intact, clipped skin of one flank using a Metalline patch of 2x3 cm. The patch was mounted on Micropore tape, which was wrapped around the abdomen and secured with Coban elastic bandage. Four hours after the application, the dressing was removed and the skin cleaned of residual test item.
- Observation period:
- Mortality/Viability: Twice daily
Toxicity: At least once daily
Body Weight: Day of treatment (prior to application) and on the day of the final observation.
Irritation: The skin reactions were assessed at approximately 1, 24, 48 and 72 hours after the removal of the dressings and test item. 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. - Number of animals:
- Three males
- Details on study design:
- The study was performed in a stepwise manner and was started by treatment of a single rabbit (sentinel). The two other animals were treated in a similar manner one week later, after considering the degree of skin irritation observed in the first animal.
Approximately 24 hours before treatment, the dorsal fur was clipped with electric clippers, exposing an area of approximately 150 square centimeters (10x15 cm). To facilitate scoring, treated skin areas were re-clipped at least 3 hours before the observations.
Each animal was treated by dermal application of 0.5 grams of the test item. The test item was moistened with 0.5 mL of the vehicle and applied to the skin of one flank, using a metalline patch of 2x3 cm. The patch was mounted on Micropore tape#, which was wrapped around the abdomen and secured with Coban elastic bandage.
Four hours after the application, the dressing was removed and the skin cleaned of residual test item using tap water.

No skin irritation was caused by 4 hours exposure toPF-06460259-01.
Based on these resultsPF-06460259-01 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 items and mixtures (including all amendments).
