Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 405 (Acute Eye Irritation / Corrosion)
- Deviations:
- yes
- Remarks:
- (reduced application amount, 72 h scoring not performed, 2 animals)
- Principles of method if other than guideline:
- BASF-test:
50 mg of the test substance were applied to the conjunctival sac of one eye of two white Vienna rabbits. Talcum powder was used as a control. Animals were observed for 8 days and skin changes were observed on working days. The substance was not washed out. Findings were graded as described in OECD test guideline 405. - GLP compliance:
- no

Any other information on results incl. tables
The talcum-treated control eyes of the animals showed slight redness of the conjunctiva (Draize scoring system 1 of 3), which was fully reversible within 48 h in both animals. In the control eye of animal #2, chemosis score 1 (of 4) could be observed at 3 h after application, which was fully reversible within 24 h.
