Super Bleach - 15%
Industrial Grade Bleach @ 15%Sodium hypochlorite
Make sure you check the % strength when comparing! This chlorine donor may be used for Soft washing solutions, routine swimming pool control. It may also be used for shock or oxidising as and when required due to it`s relative rapid reactivity.
DISINFECTING, CONCENTRATION & CONTACT TIME - Some useful info
The appropriate concentration of sodium hypochlorite for disinfecting general liquid biological waste is 5000 ppm, approximately 0.5%. For biological waste containing a high organic load (e.g. blood, proteins, or lipids) the appropriate concentration of sodium hypochlorite is 10000ppm, approximately 1%, therefore a 1:15 (v/v) dilution to liquid biological waste is appropriate.
Minimum Contact time: Surface disinfection - 1 min Liquid waste disinfection - 20 min
Important Notes: Discount brands of bleach may have lower concentrations of sodium hypochlorite and "colour safe" bleach contains NO sodium hypochlorite (hydrogen peroxide), these products should NOT be used for the disinfection of biological waste.
Sodium hypochlorite is known to be corrosive to metals, therefore, it important to rinse down metal surfaces after treating them with a bleach solution.
Chlorine and Chlorine Compounds
Overview. courtesy of FDA
Hypochlorites, the most widely used of the chlorine disinfectants, are available as liquid (e.g., sodium hypochlorite) or solid (e.g., calcium hypochlorite). 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. They have a broad spectrum of antimicrobial activity, do not leave toxic residues, are unaffected by water hardness, are inexpensive and fast acting328, remove dried or fixed organisms and biofilms from surfaces465, and have a low incidence of serious toxicity515-517. Sodium hypochlorite at the concentration used in household bleach (5.25-6.15%) can produce ocular irritation or oropharyngeal, esophageal, and gastric burns318, 518-522. Other disadvantages of hypochlorites include corrosiveness to metals in high concentrations (>500 ppm), inactivation by organic matter, discoloring or bleaching of fabrics, release of toxic chlorine gas when mixed with ammonia or acid (e.g., household cleaning agents)523-525, and relative stability327. The microbicidal activity of chlorine is attributed largely to undissociated hypochlorous acid (HOCl). The dissociation of HOCI to the less microbicidal form (hypochlorite ion OCl?) depends on pH. The disinfecting efficacy of chlorine decreases with an increase in pH that parallels the conversion of undissociated HOCI to OCl?329, 526. A potential hazard is production of the carcinogen bis(chloromethyl) ether when hypochlorite solutions contact formaldehyde527and the production of the animal carcinogen trihalomethane when hot water is hyperchlorinated528. After reviewing environmental fate and ecologic data, EPA has determined the currently registered uses of hypochlorites will not result in unreasonable adverse effects to the environment529.

Hypochlorites are widely used in healthcare facilities in a variety of settings.328Inorganic chlorine solution is used for disinfecting tonometer heads188and for spot-disinfection of countertops and floors. A 1:101:100 dilution of 5.25%6.15% sodium hypochlorite (i.e., household bleach)22, 228, 553, 554or an EPA-registered tuberculocidal disinfectant17has been recommended for decontaminating blood spills. For small spills of blood (i.e., drops of blood) on noncritical surfaces, the area can be disinfected with a 1:100 dilution of 5.25%-6.15% sodium hypochlorite or an EPA-registered tuberculocidal disinfectant. Because hypochlorites and other germicides are substantially inactivated in the presence of blood63, 548, 555, 556, large spills of blood require that the surface be cleaned before an EPA-registered disinfectant or a 1:10 (final concentration) solution of household bleach is applied557. If a sharps injury is possible, the surface initially should be decontaminated69, 318, then cleaned and disinfected (1:10 final concentration)63. Extreme care always should be taken to prevent percutaneous injury. At least 500 ppm available chlorine for 10 minutes is recommended for decontaminating CPR training manikins558. Full-strength bleach has been recommended for self-disinfection of needles and syringes used for illicit-drug injection when needle-exchange programs are not available. The difference in the recommended concentrations of bleach reflects the difficulty of cleaning the interior of needles and syringes and the use of needles and syringes for parenteral injection559. Clinicians should not alter their use of chlorine on environmental surfaces on the basis of testing methodologies that do not simulate actual disinfection practices560, 561. Other uses in healthcare include as an irrigating agent in endodontic treatment562and as a disinfectant for manikins, laundry, dental appliances, hydrotherapy tanks23, 41, regulated medical waste before disposal328, and the water distribution system in hemodialysis centers and hemodialysis machines563.
