Abstract

|
|
This evaluation tested the skin irritation and sensitization of an acaricide (Wagoojabi II®, WGJB) for the control of poultry red mite, containing 20% Chamaecyparis obtusa oil and 56% Cinnamomum camphora oil. In a primary skin irritation test, rabbits were dermally treated with WGJB for 24 h. The acaricide did not induce any adverse reactions such as erythema and edema on intact skin sites, but on abraded skin sites, some rabbits showed very slight erythema and edema 24 h after topical application. So, the acaricide was classified as a practically mild-irritating material based on a 0.625 primary irritation index score. In the skin sensitization test, guinea pigs were sensitized with intradermal injection of 0.1mL WGJB for 24 h.
After 1 week, The WGJB was treated on the site of injection, and challenged 2 weeks later. The WGJB did not induce any allergic reactions. Therefore, the WGJB was graded as a weak material at ‘0’ in both sensitization score and rate. From the results of this study, it is suggested that WGJB does not cause contact irritation and sensitization.
