Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Primary skin irritation on rabbits is recorded in a 10-grade ordinal series for the severest reaction that develops on the clipped skin of each of five albino rabbits within 24 hours of the uncovered application of 0.01 ml of test substance (undiluted or as solution in water, propylene glycol, or acetone). The scoring system was slightly similar to the method reported by Draize and associates.

SCORING SYSTEM:
The following scoring table was used:
- Grade 1: no reaction whatever from undiluted sample,
- Grade 2: an average reaction equivalent to a trace of capillary injection from undiluted sample,
- Grade 3: strong capillary injection from undiluted sample,
- Grade 4: slight erythema from undiluted sample,
- Grade 5: strong erythema, edema or slight necrosis from undiluted sample,
- Grade 6 and higher: necrosis from undiluted sample,
- Grade 6: a 10% solution gives no reaction more severe than edema
- Grade 7: indicates necrosis from a 1%s olution
- Grade 8: indicates necrosis from a 0.1% solution
- Grade 9: indicates necrosis from a 0.01% solution
- Grade 10: indicates necrosis from a 0.01% or any weaker solution.

Results
- Irritation parameter:
- overall irritation score
- Basis:
- mean
- Time point:
- other: no data
- Score:
- 6
- Max. score:
- 10
- Remarks on result:
- other: the score grade of 6 indicates that the undiluted test substance caused necrosis
