Abstract:
The antiseptics 4% chlorhexidine gluconate detergent formulation containing 4% isopropyl alcohol (Hibiclens/Hibiscrub) and 0.5% chlorhexidine gluconate in 70% isopropyl alcohol with emollients (Hibistat/Hibisol) efficiently inactivated human immunodeficiency virus (HIV) produced in cell culture within 15 seconds. These antiseptics were completely effective at 1:100 and 1:5 dilutions, respectively. Therefore, use of these products according to the manufacturer's instructions (i.e. undiluted) for routine disinfection of hands following contact with HIV-contaminated materials, as well as immediate disinfection of abrasions or cuts exposed to HIV, should have significant protective effects.
