Chlorine-containing solutions have universal disinfectant activity. With proper concentration and sufficient contact times, hypochlorite solutions can be considered chemical sterilants since they will inactivate bacterial spores.
Disinfectants and antiseptics are many active chemical compounds called biocides, which can fight microorganisms on nonliving surfaces and human skin.  These biocides, such as alcohol, iodine, and chlorine, have been used for years.
The most prevalent chlorine products in the United States are aqueous solutions of 5.25%–6.15% sodium hypochlorite (see glossary), usually called household bleach.
It means that the manufacturer has checked that the product complies with all relevant essential requirements, for example health and safety requirements. Standards for disinfectants aim to prevent manufacturers from claiming activity in a product which is not, in fact a disinfectant.
Among them Chlorine is the most widely used primary disinfectant throughout the world.
Bleach is a strong and effective disinfectant – its active ingredient sodium hypochlorite is effective in killing bacteria, fungi and viruses, including influenza virus – but it is easily inactivated by organic material. Diluted household bleach disinfects within 10–60 minutes contact time (see Table G.
70% isopropyl alcohol is by far better at killing bacteria and viruses than 99% isopropyl alcohol. As a disinfectant, 70% concentration of alcohol is the most effective at killing pathogens.
How does Dettol Liquid work? The active ingredient - Chloroxylenol - has been widely used for many years as an ingredient of antiseptic/disinfectant products. It kills bacteria and protects against the germs which can cause infection and illness.
Disinfectants can be split into two broad groups, oxidizing and nonoxidizing.
Like Clorox, Lysol products are also recognized by the EPA for being able to kill 99.9 percent of bacteria and viruses, including salmonella and COVID-19. Lysol's antibacterial cleaner is catered to kitchen messes and surfaces, thoroughly penetrating grime, grease, and dirt to leave nothing but a clean shine.
Bleach solutions will be effective against bacteria, viruses, and fungi when properly diluted. Learn more about cleaning and disinfecting surfaces using bleach solutions.
Household bleach (chlorine as sodium hypochlorite) is active against most microorganisms, including bacterial spores and can be used as a disinfectant or sanitizer, depending on its concentration.
Background: Sodium hypochlorite is the active ingredient in household bleach or chlorine bleach. It is economical, and is an effective disinfectant with a broad spectrum of antimicrobial activity. It has been the primary disinfectant used in early learning programs in Washington State for more than 30 years.
A mix of bleach and water or a bleach-based cleaner are your best bets. Also good are hydrogen peroxide and wipes made with a different type of alcohol called ethyl alcohol.
Hydrogen peroxide (H2O2) is a widely used biocide for disinfection, sterilization, and antisepsis. It is a clear, colorless liquid that is commercially available in a variety of concentrations ranging from 3 to 90%.
Currently, there are five main EPA-registered chemicals that hospitals use for disinfectants: Quaternary Ammonium, Hypochlorite, Accelerated Hydrogen Peroxide, Phenolics, and Peracetic Acid.
The results of the experiment were that bleach worked the most effectively to kill bacteria.
Hydrogen peroxide disinfection requires a high dose. The main disadvantage is the small disinfecting and oxidising ability of hydrogen peroxide at active concentrations (tens of milligrams per litre), which are required for swimming pool disinfection.
To make your own disinfecting spray that can be safely used on a variety of surfaces around your home, just combine the following ingredients in a large glass spray bottle: 1 cup water, 1 cup white vinegar, 2 tablespoons rubbing alcohol, 20 drops lemon essential oil, 20 drops tea tree essential oil.
Don't mix bleach with ammonia, acids, or other cleaners.
Mixing bleach with common cleaning products can cause serious injuries. Be sure to always read the product label before using a cleaning product.
