Type of coverage:
Preparation of test site:
Amount / concentration applied:
0.5 g test item moistened with water
Duration of treatment / exposure:
4 hours
Observation period:
1, 24, 48 and 72 hours after removal of the patches
Number of animals:
3 female rabbits
Details on study design:
The back of each animal was clipped free of hair the day prior to treatment using electric veterinary clipper (Model A2, Oster, Milwaukee, Wisconsin).
A portion of test article (0.5 g moistened with water) was applied to an area of skin approximately 6 cm2 on each animal and covered with a gauze patch. The patch was occluded and secured using a strip of impermeable adhesive tape (Sleek, Smith & Nephew, Welwyn Garden City, Herts.). A plastic collar was placed around the neck of each animal to prevent premature removal of the wrappings and ingestion of the test article. Four hours after application the patches were removed and the skin wiped with a disposable paper towel moistened with water to remove any test article still remaining.

Irritant / corrosive response data:
No irritation was noted in any animal during the 72 hour observation period. A primary irritation index of 0 was obtained. The test item was regarded as non-irritant to rabbit skin. No corrosive effects were noted.
Other effects:
Interpretation of results:
not irritating
Migrated information Criteria used for interpretation of results: EU
The substance was classified as non-irritant to skin.
Executive summary:

The test was performed in 1983 as GLP-study according to OECD 404. Three albino rabbits were treated semi-occlusive with 0.5 g test item applied on a 6 cm2 patch. Observation times were 24, 48 and 72 hours after removal of the patch. Neither erythema nor oedema were observed in all animals. A primary irritation index of 0 was obtained.

Therefore, the test item is not irritating to rabbit skin.
