Amount / concentration applied:
TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 1 - 2 g/ animal
- Concentration (suspesion): 50 %

Duration of treatment / exposure:
20 h
Observation period:
8 days
Number of animals:
4
Details on study design:
TEST SITE
- Area of exposure: 6,25 cm²

- Type of wrap if used: semi-occlusve

REMOVAL OF TEST SUBSTANCE
- Washing (if done): no
Irritation parameter:
other: No numbers were given
Remarks on result:
other: In 3 of 4 animals very slight to slight reddening was observed
Irritant / corrosive response data:
In 3 of 4 animals very slight to slight, transient reddening was observed 24 h after treatment
Other effects:
Blue discoloration by the substance
Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The test material not irritant after semi-occlusive treatment of rabbit skin for 20 hours.
Executive summary:

The skin irritation hazard was tested in rabbits by semi-occlusive application of the test material for 20 hours. Animals were treated with a 50% aqueous paste. Observations werer made after 1, 5 oand 15 minutes of contact to the skin. Afterwards animals were treated for 20 hours.

After application for short periods the skin was without any finding. Application for 20 hours caused very slight to slight reddening of the treated areas in 3 of 4 rabbits. Additionally the skin was blue discolored by the test material.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

After application for short periods the skin was without any finding. Application for 20 hours caused very slight to slight reddening of the treated areas in 3 of 4 rabbits. Additionally the skin was blue discolored by the test material.

Application of 50 mg/ animal on one eye each of several rabbits caused only slight reddening of the conjunctivae after 1 and 24 hours. No systemic effects occurred. The material was not irritant.
