Test animals

Species:
rabbit
Strain:
New Zealand White
Details on test animals or test system and environmental conditions:
Three white rabbits of New Zealand strain coming from Reproductive Farm of Rabbits, Balice were used in the experiment. The rabbits were quarantined for at least 5 days and observed carefully during this time. General medical-veterinary examination was performed on day of introduction of animals to quarantine and detailed medical-veterinary examination was performed prior to the beginning of experiment.
All animals were individually marked. Three 5-month-old males were used in the experiment.

Results of skin irritation/corrosion

During readings after 1, 24, 48 and 72 hours since the end of exposure, very slight (barely perceptible) erythema was observed on treated area of skin of all rabbits.

During reading after 7 days since the end of exposure, no pathological changes were stated on treated area of rabbits’ skin.
