Any other information on results incl. tables
Maximum concentration not causing irritating effects in preliminary test: 25 %
Signs of irritation during induction:
- Test group :
- The experimental animals showed no oedema after the 48
hours occluded epidermal induction exposure. Determination
of erythema was not possible due to red discoloration of
the treated skin.
- Control group :
Neither erythema nor edema were observed.
Evidence of sensitisation of each challenge concentration:
- CHALLENGE CONCENTRATION 25%:
9/20 (=45%) of the animals showed sensitization
Other observations:
- MORTALITY:
No mortality occured during the study.
- CLINICAL SIGNS:
No clinical signs noted during the study.
Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (skin sensitising) based on GHS criteria
- Conclusions:
- irritant
