For disinfection of most biologicals (Exception: prions and prion-like proteins), after dilution, working bleach solutions must contain between 0.5% and 2% sodium hypochlorite to be an effective disinfectant. Low levels of chloroform exposure could result in fatigue, dizziness, and headache. Sodium Hypochlorite is the main ingredient in laundry bleach. Hawkins is a large manufacturer of bleach and has multiple facilities dedicated to manufacturing and distributing high quality bleach. The molar mass of sodium hypochlorite is 74.44 g/mol. It is unstable as a solid, but solutions of up to 40% are commercially available that contain NaOH and NaCl as byproducts of the preparation: Store below eye level with compatible chemicals (Stanford Compatible Storage Group E). ("Cornell University", 1986) It's chemical formula is NaOCl, which indicates that it needs one Sodium atom, one Oxygen atom, and one Chlorine atom to create this compound. It consists of hypochlorite anion and sodium cation. Sodium hypochlorite in 0.5% w/v solution is called Dakin's solution, and is used as an antiseptic to clean infected topical wounds. This widely available product is commonly used as either a whitening and disinfecting agent in laundry or an all-purpose disinfectant with broad applications.

Boiling or splashing hazard if mixed with bleach. Exposures may cause irritation or damage to the skin, eyes, and the respiratory tract. Sodium Hypochlorite is a chlorine compound often used as a disinfectant or a bleaching agent. It is diluted with water or other filler ingredients to a concentration of about 6.0% sodium hypochlorite (NAClO). Bleach is very reactive and if it mixes with incompatible chemicals, it can produce high hazard by-products and toxic gases. It is widely used as a cleaning agent or disinfectant and bleaching agent. More concentrated solutions (10 to 15 percent) have a pH of about 13. Formula and structure: Sodium hypochlorite’s chemical formula is NaClO, and its molar mass is 74.44 g / mol.

Numerous scientific studies have shown it to be safe when used as directed on the product label. Do not use bleach on electronic equipment, optical equipment or unpainted stainless steel, Undiluted bleach and other disinfectants must not go down the drain or be mixed with other materials, Only 1:10 dilutions of bleach that have been mixed with adequate levels of protein (such as those found in tissue culture media containing fetal bovine serum) can be poured down the drain, Undiluted bleach is substantially more reactive than diluted bleach, and has even been reported to generate toxic gases such as cyanogen and chloramine when mixed with Luria broth in a ~1:1 ratio, Use stock or working bleach solutions in a well ventilated area, Work in a certified chemical fume hood when using volumes greater than 1000mL, Purchase and use the lowest volume and concentration necessary, Do not use bleach in diluted concentrations greater than 10% unless working with prions, Avoid contact with eyes, skin, and clothing, Verify the SDS and manufacturer’s guidelines for chemical compatibility before mixing bleach, Never mix bleach with incompatible chemicals, an unknown chemical, or mixture. As a bleaching agent it is usually a 5 percent sodium hypochlorite with a pH of about 11. Sodium hypochlorite is a dangerous and corrosive substance. Elevated levels of chloroform may damage the liver and kidneys. It has a sweetish and chlorine-like odour. The chemical formula is NaClO and consists of one atom of sodium (Na), one atom of chlorine (Cl) and one atom of oxygen (O). Use of bleach solutions with lower hypochlorite concentrations will not provide the proper level of disinfection. The appearance of this compound can be described as a greenish yellow solid. Liquichlor (Bleach) is manufactured as a liquid and distributed in a variety of container sizes: bulk tankers, Minibulk, totes, drums, pails and bottles. © Stanford University, Stanford, California 94305. Many household bleach solutions contain 5.25% sodium hypochlorite, and a 1:10 dilution (5250 ppm Cl) will produce a 0.53% hypochlorite solution1. It is an anhydrous unstable compound which can decompose explosively. For information on cleaning up spills, see the Spill Response Standard Operating Procedure (SOP). Will bleach kill the coronavirus? Sodium hypochlorite, the active ingredient in chlorine bleach, is routinely used in the laboratory to decontaminate surfaces and equipment or deactivate biological materials by inactivating vegetative bacteria, fungi, lipid and non-lipid viruses, and other liquid specimens. 2008-02-05. Do not use bleach with these kits! Once sodium hypochlorite has been swallowed the symptoms are stomach ache, a burning feeling, coughing, nausea, sore throat and vomiting. Sodium hypochlorite generally makes up 3-8% of the volume; dissolved in water, it has a strongly alkaline pH, which can irritate the skin. Low levels of exposure may result in eye and oral mucous membrane irritation, dizziness and nausea – while exposure to high levels may be fatal. Users should prepare a fresh bleach solution regularly. It is also tested to make certain that it contains exactly 5.25% sodium hypochlorite. The Centers for Diseases Control and Prevention (CDC) and the World Health Organization recommend ( 1 , 2 ) using a bleach solution as one way to disinfect areas contaminated with the novel coronavirus.
