Oxygen bleaches can be mixed or used with other household cleaners.Acts as a disinfectant on both bacteria and viruses likely to be encountered in the home.Environmentally safe, biodegradable, and leaves no harmful by-products or residues which can harm the environment.It is non-toxic, environmentally safe, biodegradable, and leaves no harmful by-products or residues which can harm the environment. Oxygen bleach can be used in any place in or around the house that need to be destained and deodorized it is efficient, safe and economical. Baldry (1983).Oxygen bleach is excellent for cleaning and removing organic stains (such as coffee, tea, wine, fruit juices, foods, sauces, grass and blood) from fabrics, plastics, fiberglass, porcelain, ceramics, wood, carpets, asphalt, concrete, etc. Antimicrobial Properties of Hydrogen Peroxide and Sodium Bicarbonate Individually and in Combination Against Selected Oral, Gram-negative, Facultative Bacteria Chemistry in Your Cupboard: Vanish- Learn Chemistry Cost estimates are approximating the wash phase to account for ⅓ of the total water usage per cycle. Wash cycles contain at least a wash, rinse, spin phase, with sanitising occurring in the wash phase. *Wash cycles vary from 60-75L of water used for a 7-8kg Front Loader, and 80-110L for the equivalent 7-8kg Top Loader. In the 1970s and 80s, the active ingredient in Napisan was potassium monopersulfate (KHSO5) which oxidises sodium chloride to sodium hypochlorite (chlorine bleach), but the formulation was changed and the sodium hypchlorite was replaced with sodium percarbonate (oxygen bleach). Oxygen bleach it not a viable alternative to chlorine bleach or the 90/95☌ cycle sanitise options. The approximate cost for a standard* Top Loader wash cycle: $0.80 The approximate cost for a standard* Front Loader wash cycle: $0.45 In comparison to using chlorine bleach to santise in a standard wash cycle:Ĩ0-120ml of chlorine bleach, at a cost of $2- $4/L The approximate cost for a standard* toploader wash cycle: $90 The approximate cost for a standard* front loader wash cycle: $60 If solubility was not an inhibiting factor, to sanitise using Vanish in a standard wash cycle:ġ0-20kg is needed to produce enough hydrogen peroxide, at a cost of $5-$8/kg. This means that over half the Vanish required to be able to sanitise would not actually dissolve. Sodium percarbonate is soluble at 120-150g per 1L of water. Hydrogen peroxide sanitises at 30-40% concentration (0.8mol/L), and will only oxidise ammonia (to ammonium hydroxide) at the same concentration.Īpproximately 30% of the solution would need to be Vanish, so for every 1L of water, 300gm of Vanish is required. Oxygen bleach is not an effective sanitiser for cloth nappies kills bacteria) at low concentrations, and both oxidise ammonia. The most effective, easy and inexpensive sanitisation options are chlorine bleach and 90/95☌ sanitise options. When enzymes do not function properly, the organism will die. This causes the entire molecule to change shape or collapse. When enzymes come in contact with chlorine, the hydrogens in the molecule are replaced by chlorine. Ĭhlorine kills pathogens such as bacteria and viruses by breaking the chemical bonds within the organism. Sodium hypochlorite is effective against bacteria, viruses and fungi, sanitising the same way as chlorine does. White King or the generic supermarket brand.Ĭhlorine bleach is unstable and reactive, which is why it has a shelf life, eventually turning into salt water. What is chlorine bleach?Ĭhlorine bleach is sodium hypochlorite (NaClO) diluted in water to produce a certain concentration eg 1%, 4.5% etc. Sodium percarbonate is one of the active ingredients in Vanish (previously known as Napisan). When sodium percarbonate is combined with water, it forms sodium carbonate (Na2CO3) and hydrogen peroxide (H2O2), hydrogen peroxide is the sanitising agent. Oxygen bleach is sodium percarbonate (Na2H3CO6). This produces smaller fragments which do not absorb light in the visible region of light (with respect to human sight), making the broken fragments colourless. They remove stains and sanitise by breaking bonds within a molecule.
