Results and discussion
- Positive control results:
- All animals showed positive response after intradermal induction at 5 % in mineral oil and in an emulsion of Freund's adiuvant and physiological saline and epidermal induction at 15 % in mineral oil. Challenge with positive control was done at 1 % in mineral oil 2 weeks after epidermal induction.
Performed from October 3rd to November 20th, 2000.

Any other information on results incl. tables
Maximum concentration not causing irritating effects in preliminary test
by epicutaneous application: 30 %
Signs of irritation during induction:
possible erythema reaction could not be determined due to
substance-related blue staining of the skin.
Applicant's summary and conclusion
