Executive summary:

Objective

The purpose of this study was to determine the potential irritant and/or corrosive effects of CD00006062XX on the skin of rabbits.

Methods

The test article was applied to one site on the clipped dorsal trunk of three female New Zealand White rabbits. The total exposure period was 4 hours. Observations for dermal irritation and corrosivity were recorded for each site 30 - 60 min after patch removal and at 24, 48 and 72 hours after unwarp. Grading of irritation was according to the method of Draize.

Results

The Primary Irritation Index (PII) was calculated and determined to be 0.

 Exposure  Observation Period  Dermal Observations
 4 h  30 -60 min through 72 h  No erythema and no edema

Conclusion

Under the conditions of this study, CD00006062XX, was found to be a non-irritant to the skin of rabbits with a Primary Irritation Index score of 0.
