IN-LIFE DATES: From June 6, 1990 - termination, ca. 31st June 1990
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- shaved
- Vehicle:
- other: The test material was moistened with physiological saline.
- Controls:
- not specified
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.5 gram - Duration of treatment / exposure:
- 4 h
- Observation period:
- 72 h
- Number of animals:
- 3 animals, each with two test sites.
1 female, 2 males. - Details on study design:
- TEST SITE
- Area of exposure: 2" x 2"
- % coverage: no data
- administration of test material: The test material, moistened with saline, was applied to an 8-ply gauze pad and secured with hypoallergenic tape. The entire trunk of the animal was wrapped with semi-occlusive cheesecloth bandage.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): The test sites were wiped with a gauze moistened with methanol, then rinsed with tap water.
- Time after start of exposure: 4 h post application of the test material.
- Other: The test sites were allowed to 'rest' for 30 minutes after the wrapping and pads were removed.
SCORING SYSTEM: Approximately 30 minutes after unwrapping, the test sites of each rabbit were scored for irritation using the method of:
Draize J. H., G. Woodard and H. O. Calvery, J. Pharmacol. Exp. Ther., 83, 384 (1944). The 30 minute delay was instituted to allow for regression of pressure and hydration effects.
RATING SYSTEM:
- Non Irritating: No irritation observed in any animal at any scoring interval.
- Slightly irritating: Any animal exhibiting scores of 1 or less at any scoring interval and irritation clearing within 72 hours.
- Mildly irritating: Any animal exhibiting scores of 2 or less at any scoring interval and irritationg clearing within 7 days.
- Moderately irritating: Any animal exhibiting scores of 3 or less at any scoring interval and irritation clearing within 7 days.
- Severely irritating: Any animal exhibiting scores of 4 or less at any scoring interval

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of this study and based on the FMC rating system, the test material is temporarily approximated to be non-irritating to intact skin when applied topically to New Zealand White rabbits.
This study is conducted according to an appropriate guideline and under the conditions of GLP and therefore the study is considered to be acceptable and to adequately satisfy both the guideline requirement and the regulatory requirement as a key study for this endpoint. Therefore according to Regulation (EC) No 1272/2008 on classification, labelling and packaging (CLP) of substances the test material is not considered to be classified for skin irritation. - Executive summary:
