简要总结
The aim of the study is to evaluate the irritation potential of benzalkonium chloride disinfectant spray when placed in contact with normal human skin.
详细描述
Benzalkonium chloride is recognized as safe and effective for short term use as first aid antiseptic drug products. In this study, benzalkonium chloride disinfectant spray will be compared to a positive control, and two negative control for irritancy potential on normal skin according to Chinese Patch Test Guideline (China Health Authority 2002). The skin irritation assessment will characterize the test products individually in terms of symptomatology using a 5-point categorical scale ranging from 0 (no visible reaction) to 4 (Erythema,edema˛ extreme blistering).

结局指标
主要结局
Proportion of Participants With Skin Irritation Scores at 24 Hours
时间窗: Baseline to 24 hours following product application
Irritation potential of the treatments was assessed by proportion of the irritation scores by a trained dermatologist. Skin Irritation reaction was categorized as: 0=No visible reaction; 1= Weak Erythema (Redness); 2=Erythema, Infiltration, Papule; 3= Erythema, Edema, Papule, Blister; 4=Erythema, Edema, Extreme Blistering. For the product to be deemed as non-irritant to skin, requirements were proportion of score of 2 should not be more than 1 out of 15 participants and no cases of score of 3 or 4.
Proportion of Participants With Skin Irritation Scores at 48 Hours
时间窗: Baseline to 48 hours following first product application
Irritation potential of the treatments was assessed by proportion of the irritation scores by a trained dermatologist. Skin Irritation reaction was categorized as: 0=No visible reaction; 1= Weak Erythema (Redness); 2=Erythema, Infiltration, Papule; 3= Erythema, Edema, Papule, Blister; 4=Erythema, Edema, Extreme Blistering. For the product to be deemed as non-irritant to skin, requirements were proportion of score of 2 should not be more than 1 out of 15 participants and no cases of score of 3 or 4.
Proportion of Participants With Skin Irritation Scores at 72 Hours
时间窗: Baseline to 72 hours following first product application
Irritation potential of the treatments was assessed by proportion of the irritation scores by a trained dermatologist. Skin Irritation reaction was categorized as: 0=No visible reaction; 1= Weak Erythema (Redness); 2=Erythema, Infiltration, Papule; 3= Erythema, Edema, Papule, Blister; 4=Erythema, Edema, Extreme Blistering. For the product to be deemed as non-irritant to skin, requirements were proportion of score of 2 should not be more than 1 out of 15 participants and no cases of score of 3 or 4.
