Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- Only animals in acceptable health condition were used for the test. The animals were identified by engraved ear tags. The cages were marked with individual identity cards with information about study code, sex, cage number, dose group and individual animal number. Animals were 12 weeks old, male. Rabbits were individually housed in AAALAC approved metal wire rabbit cages. Cages were of an open wire structure and cages were placed together to allow some social interaction with rabbit(s) in adjoining cages. Temperature 20+-3°C
Test system
- Type of coverage:
- occlusive
- Preparation of test site:
- clipped
- Vehicle:
- other: no vehicle
- Controls:
- other: same as test animals
- Amount / concentration applied:
- 0.5 mL on 6 cm2 skin area
- Duration of treatment / exposure:
- 4hours
- Observation period:
- 1, 24, 48 and 72 hours after treatment
- Number of animals:
- 3
- Details on study design:
- Rabbits were individually housed in AAALAC approved metal wire rabbit cages. Cages were of an open wire structure and cages were placed together to allow some social interaction with rabbit(s) in adjoining cages.
The test item was applied to an approximately 6 cm² area of intact skin as follows:
• A single layer of a fine medical gauze (open-weave with large holes) of approximately 5x5 cm was placed over the application area,
• The appropriate amount of test item was carefully spread over the application area (the gauze helped maintain the test item in place),
• Three more layers of gauze were placed over the test item,
• These gauze patches were kept in contact with the skin by a patch of clear plastic with a surrounding adhesive hypoallergenic plaster to ensure continued good contact between the test item and the shaved skin.
• The entire trunks of the animals were wrapped with plastic wrap for 4 hours.
• Medical elastic tubing was placed over the plastic to keep it in place.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Conclusions:
- According to Directive 2001/59/EC, PETASAN does not require classification as a skin irritant.
According to the UN Globally Harmonised System of Classification and Labelling of Chemicals, PETASAN does not require classification as a skin irritant.
According to the classification system based on the scheme devised by Draize (1959), PETASAN is a "non-irritant". - Executive summary:
An acute skin irritation study was performed with PETASAN in New Zealand White rabbits. Parameters monitored during this study included mortality, body weight measurements and clinical observations. The irritancy of the test item was evaluated according to the Draize method (OECD No.: 404, 2002). A volume of 0.5 ml test item was applied to the skin of the experimental animals. The test item was applied as a single dose. An adhesive clear plastic patch was applied. The trunk was wrapped in clear plastic with medical tubing used to hold the patch in place. The untreated skin of each animal served as control. After 4 hours, the remaining test item was removed with water at body temperature. To assess skin irritation, animals were examined at 1, 24, 48 and 72 hours after the patch removal. Additional general examinations were performed daily. There was no mortality or systemic clinical changes related to PETASAN administration. There was no effect of treatment on body weight. At observation one, 24, 48 and 72 hours after patch removal, there were no observed clinical signs noted on the skin of the treated animals. As no clinical signs were observed the study was terminated after the 72 hours observation. The animals’ individual mean scores (considering readings at 24, 48 and 72 hours after patch removal) for erythema and oedema were 0.00, 0.00 and 0.00 respectively. According to Directive 2001/59/EC, PETASAN does not require classification as a skin irritant. According to the UN Globally Harmonised System of Classification and Labelling of Chemicals, PETASAN does not require classification as a skin irritant. According to the classification system based on the scheme devised by Draize (1959), PETASAN is a "non-irritant".
