If an explosive molecule contains just enough oxygen to form carbon dioxide from carbon, water from hydrogen atoms, all of its sulfur dioxide from sulfur, and all metal oxides from metals with no excess, the molecule is said to have a zero oxygen balance. It has been used as antiseptic compound in medicine since 1930s. Zinc peroxide is very hazardous in case of skin contact, of eye contact, ingestion, or inhalation. Zinc peroxide was, however, deemed ineffective against certain bacterial strains, such as Streptococcus viridans, staphylococcus aureus, E. coli, B. proteus, and B. pyocyoneus. Repeated or prolonged exposure can produce organ damage. While these stains can produce a variety of colors ranging from a reddish brown to a yellow hue, they are generally used to mimic the look of endangered wood species in cheaper and more commonly available stock.[7]. It has been suggested that the increase in oxygen concentration associated with the presence of ZnO2 interferes with the replicative processes of anaerobic and micro-aerophillic organisms, both of which require low oxygen environments for their survival. It was historically used as a surgical antiseptic. Zinc peroxide (ZnO2) appears as a bright yellow powder at room temperature. It has been shown to be corrosive to skin. [4] Compounds of zinc are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. Note that rounding errors may occur, so always check the results.
