The present invention relates to a composition in a solution (often an aqueous solution) comprising a combination of an acceptable source of molecular iodine (I 2 ) and an iodate (IO 3- ) and an acid (inorganic or organic), wherein iodine and iodine The acid salt is present in the composition in a molar ratio of about 0.1 to about 25 and the concentration of the non-complex molecular iodine is an effective amount (depending on the final use of the composition) of disinfection, biocidal and / or antimicrobial, Lt; / RTI >; to about 6.5 in the composition. The compositions according to the present invention are unexpectedly stable for extended periods of time (up to 5 years) and can be sterilized solutions, sterilizing agents for various surfaces and / or biocides (e.g., antiviral, antibacterial, And their activity (due to their high concentration of free molecular iodine in solution), their reduced environmental impacts (because of their high concentration of free radicals iodine in solution), their low cost, their use of reduced iodine, their activity , Their long-term storage stability and their reduced toxicity. They also have particular utility in processing on food surfaces to delay corruption, increase shelf-life and minimize human and economic costs of food disposal. The compositions inactivate viruses, bacteria (both gram positive and gram negative), spores and fungi. The compositions according to the present invention can be used and stored in a variety of materials in which such compositions appear in the absence of substantial spoilage (non-perishable). Dental compositions (e.g., pre-operative rinses and other compositions) and methods associated therewith are also disclosed.본 발명은 분자 요오드(I2) 및 요오드산염(IO3-)의 수용 가능한 소스의 조합, 및 산(무기 또는 유기)을 포함하는 용액(흔히, 수성 용액) 내의 조성물에 관한 것으로서, 요오드 및 요오드산염은 약 0.1 대 약 25의 몰 비율로 조성물 내에 존재하며, 비복합 분자 요오드의 농도는 소독, 살생물 및/또는 항균(조성물의 최종 사용에 의존하여) 유효량이며 조성물 내의 산의 농도는 약 1.5부터 약 6.5까지 범위의 조성물 내의 완충 pH를 제공하기에 효과적이다. 본 발명에 따른 조성물들은 예상치 않게 장
