In rats, this dose was 1000 mg/kg/day, which is approximately 24 times a human dose of 200 mg twice daily based on mg/m 2 /day. In rabbits, the highest dose tested was 90 mg/kg/day, which is approximately four times a human dose of 200 mg twice daily based on mg/m 2 /day. This dose produced severe maternal toxicity and resulted in fetal ...
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.

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.
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.
The resin has a higher affinity for highly charged countercations, for example by Ca 2+ (calcium) in the case of water softening. Correspondingly, anion-exchange resins are typically provided in the form of chloride Cl −, which is a highly mobile counteranion. Counterions are used in phase-transfer catalysis.
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". Named after Joseph Lister, who pioneered antiseptic surgery at the Glasgow Royal Infirmary in Scotland, Listerine was developed in 1879 by Joseph Lawrence, a chemist in St. Louis, Missouri.
Activated carbon. Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area [1] [2] available for adsorption or chemical reactions. [3]
