Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 405 (Acute Eye Irritation / Corrosion)
- Deviations:
- yes
- Remarks:
- not under GLP conditions (studies dates 1983)
- Principles of method if other than guideline:
- Six animals are dived per two and were treated as follows:
Group 1- the test substance is added and not rinsed.
Group 2- the test substance is rinsed after 4 seconds with 0.5% alcohol.
Group 3- the test substance is rinsed after 8 seconds with 0.5% alcohol.
In all treated animals the other eye serves as negative control. Irritation is scored after 24, 48, 72 hours, and after 4 and 7 days conform Draize. - GLP compliance:
- not specified
