The present invention relates to a solution (often an aqueous solution) comprising a combination of molecular iodine (I2) and an acceptable source of iodate (IO3) and an acid (inorganic or organic acid). Intended for the composition. Here, iodide and iodate are present in the composition in a molar ratio of about 0.1 to about 25, and the concentration of uncomplexed molecular iodine is determined by disinfectant, biocide, and / or antimicrobial. An amount effective as an agent (depending on the end use of the composition), the concentration of the acid in the composition providing the composition with a buffered pH that ranges from about 1.5 to about 6.5. Therefore, it is an effective concentration. The composition according to the invention is storage-stable for an unexpectedly long period (up to about 5 years), as a disinfectant for various surfaces and solutions, including biological and inanimate surfaces, and as a disinfectant and / or Find uses as biocides (eg antiviral, antibacterial, antifungal, antispore, etc.), low cost, low iodine usage, activity (free molecular iodine in solution Are particularly useful because of their reduced environmental impact, long-term storage stability, and low toxicity. These compositions are also particularly useful in treating the surface of food to delay spoilage, increase useful shelf life, and minimize human and economic costs of food waste. The composition inactivates viruses, bacteria (both gram negative and gram positive bacteria), spores and fungi. Compositions according to the present invention can be used and stored in a variety of materials, provided that these compositions exhibit a substantial lack of corrosivity (non-corrosive). Also disclosed are dental compositions (eg, pretreatment rinses and other compositions) and related methods.本発明は、分子状ヨウ素（Ｉ2）と、ヨウ素酸塩（ＩＯ3）の許容され得る供給源との組み合わせと、酸（無機酸又は有機酸）とを含む溶液（多くの場合、水溶液）中の組成物を対象とする。ここでは、ヨウ化物及びヨウ素酸塩は、約０．１対約２５のモル比で組成物中に存在し、非錯体化分子状ヨウ素の濃度は、消毒剤、殺生物剤、及び／又は抗菌剤（組成物の最終的な用途に応じて）として有効な量で
