Constituent 1
Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- At the start of the study the rabbits weighed 2.0 to 3.5 kg and were twelve to sixteen weeks old. Free access to mains drinking water and food was allowed through out the study. The temperature and relative humidity were set to achieve limits of 17 to 23 C and 30 to 70% respectively. The rate of air exchange was at least 15 changes per hour and the lighting was controlled by a time switch to give 12 hours continuous light and 12 hours of darkness.
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- shaved
- Vehicle:
- other:
- Controls:
- not required
- Amount / concentration applied:
- 0.5 g of the test material, moistened with 0.5 ml of distilled water was introduced under 2.5 cm X 2.5 cm cotton gauze patch
- Duration of treatment / exposure:
- 4 hours after treatment.
- Observation period:
- Approximately one hour after removing the patch and 24, 48 and 72 hours later, the test sites were examined for evidence of primary irritation and scored.
- Number of animals:
- 3
- Details on study design:
- The day before the test the three rabbits were clipped free of fur from the dorsal/flank area and inspected for gross abnormalities of the epidermis. Only animals with an intact healthy epidermis are selected for the study. Initially only one animal was treated with three sites on the back of the rabbit selected. At each test site 0.5 g of test material moistened with 0.5 ml of distilled water was introduced under a 2.5 cm X 2.5 cm cotton gauze patch which was secured in position with surgical tape. The animal was then placed in a corset to avoid the rabbit interfering with the patch and one patch removed at each of 3 times: 3 minute, 1 hour, and 4 hours. After review of skin irritations for the first rabbit, 2 additional rabbits were treated and then 4 hours later the patches were removed. The test sites were ten evaluated after 1 hour, 24, 48, and 72 hours according to the Draize classification scheme for determination of primary irritation index.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test material produced a primary irritation index of 0.0 and was classified as a non-irritant to rabbit skin according to the Draize classification scheme. No corrosive effects were noted. The test material did not meet the classification as irritant or corrosive according to the EU labelling regulations.
- Executive summary:
Studies were assigned reliability of 1 and followed acceptable OECD, EU or recognised standards and were in accordance with GLP. The test material produced a primary irritation index of 0.0 and was classified as a non-irritant to rabbit skin according to the Draize classification scheme. No corrosive effects were noted.
