In November 2020 the Journal of Hospital Infection published a study on benzalkonium chloride formulations; it was found that laboratory and commercial disinfectants with as little as 0.13% benzalkonium chloride inactivated the SARS-CoV-2 virus within 15 seconds of contact, even in the presence of a soil or hard water.

TWA 0.05 mg/m 3 (0.005 ppm) C 0.2 mg/m 3 (0.020 ... It is a potentially violently reactive material towards water and other nucleophiles. References
Sodium hypochlorite can also be used for point-of-use disinfection of drinking water, [40] taking 0.2–2 mg of sodium hypochlorite per liter of water. [41] Dilute solutions (50 ppm to 1.5%) are found in disinfecting sprays and wipes used on hard surfaces. [42] [43]
Second, they are based on direct, experimentally determined values for transfer free energies of polypeptides. Two whole-residue hydrophobicity scales have been measured: One for the transfer of unfolded chains from water to the bilayer interface (referred to as the Wimley–White interfacial hydrophobicity scale).
Oxalic acid's main applications include cleaning or bleaching, especially for the removal of rust (iron complexing agent). Its utility in rust removal agents is due to its forming a stable, water-soluble salt with ferric iron, ferrioxalate ion. Oxalic acid is an ingredient in some tooth whitening products.
Lysol (/ ˈ l aɪ s ɒ l /; spelled Lizol in India [1]) is a brand of American cleaning and disinfecting products distributed by Reckitt, which markets the similar Dettol or Sagrotan in other markets. The line includes liquid solutions for hard and soft surfaces, air treatment, and hand washing.
The tissue response (y-axis) to an agonist, in log concentration (x-axis), in the presence of different antagonist concentrations. The EC 50 of the agonist is represented by the x co-ordinate that corresponds with the half-maximum of the leftmost curve.
Listerine (/ ˈ l ɪ s t ər iː n /) is a brand of antiseptic mouthwash that is promoted with the slogan "Kills germs that cause bad breath".
