- Six New Zealand White rabbits, free from any obvious skin lesions and weighing not less than 2.0 kg were used for the study. They were obtained from Buxted Rabbit Co. Ltd., Great Totease Farm, Buxted, Nr. Uckfield, Sussex.
Diet
The animals were allowed unlimited access to mains water and food (Standard Rabbit Diet - BP Nutrition (U.K.) Ltd., Stepfield, Witham, Essex) throughout the study.

- Procedure and observations
The animals were identified by a number stamped on a metal ear tag.
Twenty four hours prior to treatment, the back of each animal was shaved using electric clippers. One side of the shaven area on each animal was left intact. The other side of the shaven area was abraded using a sterile hypodermic needle to scratch a 5 x 5 lattice in an area measuring 2.5 cm x 2.5 cm such that only the stratum corneum was penetrated and bleeding did not occur. The test article (0.5 .g) was applied under gauze pads (2.5 cm x 2.5 cm) to the intact and abraded areas of each rabbit.
The patches were secured by adhesive strapping and the whole trunk further occluded with a stockinette bandage.
Twenty four hours after administration the patches were removed and the skin reactions on both the intact and abraded areas of each rabbit were scored according to Draize, J.H. (1959), Assoc. of Food and Drug Officials of the U.S., Austin, Texas, "The Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics.". The evaluation was repeated 48 hours later (72 hours after administration) and finally 7 days after administration if any irritation was apparent at the 72 hour reading. - Irritation parameter:

- Executive summary:
The study was carried out to determine the primary irritation index of test article in the albino rabbit. The study was performed in accordance with the Standard Operating Procedures as applied to the ETAD test method 14.10.76 from Code of Federal Regulations, Title 16, Section 140041.
Six New Zealand White rabbits, free from any obvious skin lesions and weighing not less than 2.0 kg were used for the study.

Results
The primary irritation index of test article was 0.0. The test article was therefore classified as a non irritant.
Red/brown staining of the test area and surrounding skin made the irritation assessment difficult.
Conclusion
A primary skin irritation study was performed in the albino rabbit on the test article.
A primary irritation index of 0.0 was obtained. The test article is therefore classified as a non-irritant.

- Six New .Zealand White rabbits obtained from Buxted Rabbit Co. Ltd., Great Totease Farm, Buxted, Nr. Uckfield, Sussex were used for the study. At commencement the animals were free from any eye irritation or defects.
Diet
The animals were allowed unlimited access to filtered mains water and food (Standard Rabbit Diet, BP Nutrition (U.K.) Ltd., Stepfield, Witham, Essex) throughout the study.
Environment
The animals were housed individually in grid floor cages in a single room maintained under conditions of ambient humidity and temperature except that a lower temperature of 14°C is automatically imposed. - Vehicle:
- unchanged (no vehicle)
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- 100 mg
- Duration of treatment / exposure:
- 72 hours (no washing following installation of test article)
- Observation period (in vivo):
- 72 hours
- Number of animals or in vitro replicates:
- 6 animals
- Details on study design:
- The animals were identified by an indelible number marked on the inner surface of the pinna. The test article (100 mg) was placed in one eye of each animal by gently pulling the lower lid away from the eyeball to form a cup into which the test substance was dropped.
The lids were then gently held together for about one second. The other eye, remaining untreated, served as a control. The eyes were not washed following instillation of the test article.
The eyes were examined 1 hour, 24 hours, 48 hours and 72 hours after instillation and the degree of irritation was scored according to: Draize, J.H. (1959), Assoc. of Food and Drug Officials of the U.S., Austin, Texas, "The Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics". Where a substance caused irritation within the first three days after administration the ocular reaction was also assessed on the seventh day. This value was not included in the calculation of the irritant score. - Irritation parameter:

Additional information
A study was carried out to determine the primary irritation index of test article in the albino rabbit. The study was performed in accordance with the Standard Operating Procedures as applied to the ETAD test method 14.10.76 from Code of Federal Regulations, Title 16, Section 140041.
Six New Zealand White rabbits, free from any obvious skin lesions and weighing not less than 2.0 kg were used for the study.
Twentyfour hours prior to treatment, the back of each animal was shaved using electric clippers. One side of the shaven area on each animal was left intact. The other side of the shaven area was abraded using a sterile hypodermic needle. The test article (0.5 g) was applied under gauze pads to the intact and abraded areas of each rabbit. The patches were secured by adhesive strapping and the whole trunk further occluded with a stockinette bandage.
Twentyfour hours after administration the patches were removed and the skin reactions on both the intact and abraded areas of each rabbit were scored. The evaluation was repeated 48 hours later (72 hours after administration) and finally 7 days after administration if any irritation was apparent at the 72 hour reading.
No systemic or local effects were noted during the study. The primary irritation index of test article was 0.0. The test article was therefore classified as a non irritant.
A study was carried out to determine the eye irritation score of test article in the albino rabbit.
The study was performed in accordance with Standard Operating Procedures as applied to ETAD test method 14.10.76 from Code of Federal Regulations.
Six New Zealand White rabbits were used for the study. At commencement the animals were free from any eye irritation or defects.
The test article (100 mg) was placed in one eye of each animal by gently pulling the lower lid away from the eyeball to form a cup into which the test substance was dropped. The lids were then gently held together for about one second. The other eye, remaining untreated, served as a control. The eyes were not washed following instillation of the test article.
The eyes were examined 1 hour, 24 hours, 48 hours and 72 hours after instillation and the degree of irritation was scored.
Where a substance caused slight irritation within the first three days after administration the ocular reaction was also assessed on the seventh day. This value was not included in the calculation of the irritant score.
Slight conjunctival reddening ans swelling was seen up to 48 and 24 hours, respectively.
An eye irritation score of 2.3 was obtained. The test article is therefore regarded as a non irritant.
Justification for classification or non-classification
Due to the lack of irritation signs in both skin and eye irritation in vivo studies, the test item is not classifiable according to CLP criteria.
