[In vitro virucidal activity of antiseptics and disinfectants. II. Simple dilution technic]. / Activité virucide in vitro des antiseptiques et désinfectants. II. Technique par dilution simple.

The simple dilution technique is based on termination of the tested agent's antiviral activity by sudden cold dilution (D). It can be used only if D less than or equal to 10(3) but is the most simple method. We used this technique to study ATS and demonstrate the strong virucidal activity of glutaraldehyde, inefficiency of chlorhexidine digluconate and questionable activity of povidone-iodine and noxythiolin.
