Other effects:
Red Brown staining of the treated skin by the test
substance was observed throughout the observation period,
which did not hamper the scoring of the skin reactions.

No remnants of the test substance were present on the skin.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
There were no systemic adverse effects including effects on clinical signs of toxicity and body weight observed in all animals. The Everzol SB45 could cause irritant response to skin and reverse within 72 hours.
