Objective:
To determine the irritant or corrosive effects, if any, of a test article when applied to the skin of a rabbit. This study was designed to comply with the standards set forth in the current OECD Guideline for Testing of Chemicals, Number 404 Acute Dermal Irritation/Corrosion.
Method Synopsis:
Since the test article was not expected to produce severe irritation or corrosion, three healthy New Zealand White rabbits (one male - two females) were dosed dermally with RD 14156. The test article (0.5 g) was applied dermally to one intact site per rabbit and wrapped with a semi-occlusive dressing. The test article was kept in contact with the skin for 4 hours at which time the wrappings were removed. Erythema and edema were scored at 1, 24, 48 and 72 hours. The skin was also evaluated for ulceration and necrosis or any evidence of tissue destruction at these time periods. Animals were observed for mortality, toxicological and pharmacological effects at each dermal observation period. Body weights were recorded pretest and at termination.
Summary:
No. of animals Dermal responses (time post exposure) Erythema Edema Addiitonal dermal observations Four-hour exposure 3 1 hr Absent to very slight Absent NA 3 24 hr Absent Absent NA 3 48 hr Absent Absent NA 3 72 hr Absent Absent NA Systemic Observations No abnormal physical signs were observed Body weights One animal gained bodyweight by study termination and two animals' weight remained the same Conclusion RC 14156 is not a dermal irritant NA = Not Applicable
