  • Title: Virucidal efficacy of a combination of 0.2% peracetic acid and 80% (v/v) ethanol (PAA-ethanol) as a potential hand disinfectant.
    Author: Wutzler P, Sauerbrei A.
    Journal: J Hosp Infect; 2000 Dec; 46(4):304-8. PubMed ID: 11170762.
    Abstract:
    The formulation PAA-ethanol, consisting of 0.2% paracetic acid (PAA) and 80% ethanol, was tested for its virucidal activity on the enveloped vaccinia virus and papova virus SV 40 and the non-enveloped adenovirus type 2 and poliovirus type 1. All test viruses were inactivated by PAA-ethanol within an exposure time of 1 minute, as measured by a log(10)reduction of 4 in virus titres. It was shown that poliovirus type 1 can be inactivated by PAA-ethanol within 1 min, whilst for the aqueous 0.2% PAA solution, an exposure time of 5 min is necessary. As shown by electron microscopic observation, the structure of virus particles was completely destroyed by 0.2% PAA within 15 min. The broad antimicrobial spectrum including a high virucidal activity, short exposure time and no toxic or allergenic decomposition products are favourable prerequisites for the medical use of PAA-ethanol and it warrants further investigation as a hand disinfectant.
