SOLUTION FOR RAY IRRADIATION CLEANING IN ULTRAVIOLET OR/AND NEAR-ULTRAVIOLET RAY OR/AND INFRARED RAY NEIGHBOR REGION OF 800-900 NM, DENTIFRICE CONTAINING THE SAME, DENTISTRY THERAPEUTIC DEVICE, TOOTHBRUSH AND METHOD FOR CLEANING TEETH
PROBLEM TO BE SOLVED: To provide a hydrogen peroxide aqueous solution useful for oral cavity cleaning, which can suppress generation of carcinogenic substances or materials harmful to human body with degradation of a stabilizer and generation of other materials derived from the stabilizer in oral cavity due to hydroxy radical generated by degradation of hydrogen peroxide and is safer.SOLUTION: There is provided a solution for ray irradiation cleaning in ultraviolet or/and near-ultraviolet ray or/and infrared ray neighboring region of 800-900 nm in oral cavity, having concentration of hydrogen peroxide of 1-7 w/v%, preferably 2-6 w/v% and concentration of hydrogen oxide stabilizer which is one or more of phosphoric acid, phenacetin, acetanilide for example of 81 ppm (mg/L) or less.SELECTED DRAWING: Figure 3【課題】過酸化水素の分解によって生じるヒドロキシラジカルが原因となる口腔内での安定剤の分解、安定剤由来の他の物質の合成に伴って危惧される発がん性物質や人体に有毒の物質の発生を少なく抑制できより安全な口腔内クリーニングに有用な過酸化水素水溶液の提供。【解決手段】過酸化水素の濃度が1~7w/v%、好ましくは2~6w/v%であり、例えばリン酸、フェナセチン、アセトアニリドのいずれか一以上である酸化水素安定剤の濃度が81ppm(mg/L)以下である口腔内の紫外線又は/及び近紫外可視光線又は/及び800~900nmの赤外線近傍領域光線照射クリーニング用水溶液。【選択図】図3
