requirements, such that they can be handled by consumers and used in the <br /> environment to deliver the benefits asspecified <br /> in roduct claims. <br /> . P <br /> Magnesium peroxide is listed in the Merck Index as an digestive antiacid making it <br /> safe to ingest. One such product is currently being sold under the trade name <br /> Homozone. It has several obscure food uses and has been trialed in dentifrices to <br /> generate oxygen under the gumline to prevent periodontal disease caused by <br /> anaerobic microorganisms. The co-inventor of ORC, Dr. William Farone, helped <br /> develop these applications almost twenty years ago in his capacity as Director of <br /> Research at Lever Brothers. The product applications eventually surfaced just <br /> recently, in a slightly different form, as Mentadent toothpaste which has just been <br /> launched by Cheesboro-Ponds. <br /> f <br /> 2. Mode of Action and Reactivity <br /> S <br /> Oxygen is an absolute requirement for the maintenance aerobic microorganisms that <br /> degrade hydrocarbons. By providing oxygen with ORC we facilitate the conversion of <br /> aromatic hydrocarbons, such as BTEX compounds, to various biological molecules <br /> synthesized by the remediating microorganisms, and then ultimately to carbon dioxide. <br /> Using benzene as an example the basic equation describing the eventual <br /> mineralization to carbon dioxide is: <br /> C6H6+ 7.502—> 6COZ + 31-120 <br /> The biological intermediates that exist on the way to carbon dioxide are varied and at <br /> any given point can be utilized to generate the elements of cellular structure. In the <br /> case of benzene, the first step is the formation of catechol. Compounds like toluene <br /> will go through several intermediates such as benzyl alcohol, benzaldehyde and <br /> benzoic acid before becoming catechol. This basic reaction is <br /> C61-16 + 02 —> C6H602 <br /> Catechol can then undergo an ortho or meta fission. Ortho fission leads to the <br /> production of acetyl CoA and succinate while meta fission leads to the production of <br /> acetaldehyde and pyruvate. As these materials enter the TCA cycle they will ultimately <br /> become carbon dioxide, water while contributing to the formation of cellular energy <br /> products. <br /> The oxygen that drives the above reactions is released by ORC when it is contacted <br /> with water. This reaction proceeds according to the overall equation: <br /> M902 + H2O -. V2021 + Mg(OH)2 <br /> i <br />
