Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 406 (Skin Sensitisation)
- Version / remarks:
- adopted in 1992
- Deviations:
- yes

- RANGE FINDING TESTS:
Intradermal:
Two animals were administered intradermal injections (2 injection / animal) of a 5% v/v concentration of test substance in propylene glycol, one on either side of the spinal column. The concentration tested did not produce extensive tissue damage or severe systemic toxicity.
Topical:
4 animals were tested at 4 different concentrations (25, 50, 75% v/v; 100%) per animal (one concentration/site), two on either side of the spinal column. 24 h and 48 h after removal of the patches no signs of erythema and edema were observed for at any of the concentration tested.
