How do detergents inactivate viruses
WebAbstract. The activity of a number of detergents and disinfectants against respiratory syncytial virus (RSV) was evaluated in an in vitro assay system. Equal volumes of RSV and serial 10-fold dilutions of the test agents were mixed at 4 degrees C for 5 minutes. The RSV titer in each mixture was compared with that of untreated RSV alone. WebNonionic (uncharged) detergents are very good emulsifiers, have good penetration and dispersion, are effective at lowering surface tension, and have reduced foaming properties. These products do not typically complex with metallic ions, such as those found in hard water. Most commercial detergents are a combination of anionic and non-ionic. 2

WebSolvent/detergent treatment. Solvent/detergent treatments disrupt the lipid membrane of enveloped viruses and lead to inactivation, a critical step in many viral clearance strategies. They can be used as an orthogonal method for pH inactivation or as a replacement for pH inactivation in the production or extraction of pH-sensitive molecules.
WebNov 20, 2014 · Inactivation steps, such as low pH, detergent, or irradiation, are important contributors to the total clearance obtained, and regulatory agencies expect to see at least one effective inactivation step in a purification process.
