- Housing: metal cages
- Diet and water: fed with standard diet of Nafag and drinking water ad libitum
- Acclimation period: the animals were acclimatized to the environment in laboratories for at least 8 days
ENVIRONMENTAL CONDITIONS

- Vehicle:
- water
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- Amount of 0.5 g of test substance were applied
- Duration of treatment / exposure:
- The gauze patches were removed 24 hours after application
- Observation period:
- The reaction of the skin was appraised upon removal during an observation period of 8 days
- Number of animals:
- 6 (3 males and 3 females) rabbits
- Details on study design:
- TEST SITE
- Area of exposure: shaved one day before treatment. The shaved skin area on the left side was slightly scarified immediately before treatment. A gauze patch of 2.5x2.5 cm laden with the test substance was immediately applied to the prepared skin.
- Type of wrap if used: the patch was covered with an impermeable foil of 5x5 cm, which was fixed to the body of the animals with adesive tape.
SCORING SYSTEM: The reaction of the skin was appraised upon removal during an observation period of 8 days.

- Executive summary:
METHOD
The skin irritation test was performed to rabbit skin using a single administration, according to the "Appraisal of the Safety of Chemicals in Food, Drugs and Cosmetics" (1959) of the US Association of Food and Drug Officials (AFDO).
RESULT/CONCLUSION
The criteria for the evaluation of the skin irritation potential followed in the test are different from those reported into the OECD guideline. Nevertheless, the scoring system used for the erythema and eschar formation and for oedema formation are the same of that reported into the OECD. Since the raw tables are included into the study report, it is possible to re-evaluate the results according to the CLP Regulation (EC n. 1272/2008).
The test substance was found to be non irritant when applied to intact or abraded rabbit skin.
Therefore, the test substance can be classified as NON IRRITATING, according to the CLP Regulation (EC n. 1272/2008).
