Description of key information
Skin irritation: The potential of test item to cause inflammatory or corrosive changes upon first contact with skin was assessed by semi-occluded application of 0.5 g of the test material to the closely-clipped dorsa of three New Zealand White rabbits for four hours based on OECD 404. Under the conditions of this test, the test item was classified as 'non-irritant' to the skin.
Eye irritation: The potential of test item to cause damage to the conjunctiva, iris or cornea was assessed in three New Zealand White rabbits based on OECD 405. Under the conditions of this test, the test item was classified as 'non-irritant' to the eye.

- Source: Ranch Rabbits, Crawley Down, Sussex, England
- Age at study initiation: approximately three months
- Weight at study initiation: 2.52-2.82 kg
- Housing: They were individually housed in suspended stainless steel cages (Type RC10/L) mounted in mobile batteries (Modular Systems and Development Company Limited, London, England). The cages measured 61 x 76 x 46 cm high and were fitted with perforated counter-sunk floor panels. A tray beneath the floor was lined with absorbent crepe paper which was changed regularly.
- Diet (e.g. ad libitum): free access to a commercially available standard pelleted rabbit diet (S.Q.C.Rabbit Diet, Special Diet Services Limited, Witham, Essex, England). The diet contained no added antibiotic or other chemotherapeutic or prophylactic treatment.
- Water (e.g. ad libitum): free access to tap water. The water was taken from the public supply; in England the supply and quality of this water is governed by Department of the Environment regulations. There was no information indicating that normal levels of common contaminants would influence the outcome of the study.
- Acclimation period: An acclimatisation period of seven days was allowed between arrival at the laboratory and administration of the test material.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 18°C (range 15°-23°C)
- Humidity (%): 55% R.H. (range 40%-70% R.H.)
- Air changes (per hr): 15 complete air changes per hour without re-circulation.

- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.5g - Duration of treatment / exposure:
- 4 hours

- Area of exposure: the dorsum between the limb (6 x 6 cm) girdles
- Type of wrap if used: A single dose (0.5 g) was applied directly to the skin and covered by an unmedicated gauze patch (3 x 2 cm) which was held in place on the left test site by strips of Blenderm (3-M Company). The right test site, acting as a control, was covered by a similar semi-occlusive dressing but otherwise remained untreated. Pads of cotton wool and elasticated bandage were used to protect the patches and ensure good contact between the skin and the test material during the four-hour exposure period. The elasticated bandage was held in place by thin strips of waterproof plaster ('Sleek' - T &J Smith and Nephew Limited) at both edges.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): the treatment sites were then gently washed with warm water and dried with paper towels to remove excess test material adhering to the skin.
- Time after start of exposure: 4 hours

- Irritant / corrosive response data:
- Injection of the conjunctival blood vessels was observed in two rabbits one hour following instillation of test item, and continued in one animal at the 24 hour examination. A crimson-red conjunctival appearance and very slight chemosis and discharge were observed in the remaining rabbit at the one hour examination; injection of the conjunctival blood vessels persisted in this animal to the 48 hour assessment.
- Other effects:
- Instillation of the test material caused practically no initial pain response.
The eyes of all rabbits were overtly normal by the 72 hour examination. - Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this test, the test item was classified as 'non-irritant' to the eye.
- Executive summary:
The potential of test item to cause damage to the conjunctiva, iris or cornea was assessed in three New Zealand White rabbits based on OECD 405, each subject to single ocular instillation of 100 mg of the test material. Ocular reactions were examined 1, 24, 48 and 72 hours after treatment. Injection of the conjunctival blood vessels was observed in two rabbits one and/or 24 hours following instillation. The third rabbit showed a crimson-red conjunctival appearance, slight chemosis and discharge at the one hour examination and injection of the conjunctival blood vessels up to the 48 hour assessment. The eyes of all rabbits were overtly normal by the 72 hour examination. Instillation of the test material caused practically no initial pain response. Under the conditions of this test, the test item was classified as 'non-irritant' to the eye.
