Test animals
- Species:
- rabbit
- Strain:
- not specified
Test system
- Type of coverage:
- occlusive
- Preparation of test site:
- shaved
- Vehicle:
- unchanged (no vehicle)
- Controls:
- no
- Amount / concentration applied:
- 0.5g
- Duration of treatment / exposure:
- 24 hours.
- Observation period:
- 72 hours.
- Number of animals:
- Six.
- Details on study design:
- The test material was used as supplied. A group of six albino rabbits were clipped over a wide area. One side of the rabbits back was allowed to remain intact. A 0.5 g portion of material was applied to the intact skin site. Gauze patches were then placed over the treated area and an impervious material was wrapped snugly around the trunks of the animals to hold the patch in place.
The wrapping was removed at the end of the 24 hour period and the treated areas were examined. Reading were also made after 72 hours.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- 0/6 animals showed evidence of skin irritation in the study, therefore, ZMB2 is not classified as an irritant.
