Brief Summary

The aim of the study is to evaluate the irritation potential of benzalkonium chloride disinfectant spray when placed in contact with normal human skin.

Detailed Description

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).

6. Personnel: An employee of the sponsor or the study site or members of their immediate family.

7. Participant who is currently taking any of the following medications:
