Hydrogen peroxide (tshuaj lom neeg cov tshuaj: H2O2), cov tshuaj hydrogen hydrogen ntshiab yog lub teeb xiav dej ua kua nyeem uas tsis tuaj yeem tsis haum nrog dej hauv ib qho kev sib faib. Nws yog ib qho muaj zog oxidant, thiab nws cov kua aqueous feem ntau hu ua hydrogen peroxide. Nws yog cov kua tsis muaj xim thiab pob tshab. Nws cov kua dej aqueous yog qhov tsim nyog rau kev kho mob lub qhov txhab kho kab mob, ib puag ncig kev ua kom huv thiab zaub mov ntxuav kab mob. Nyob rau hauv ib txwm muaj xwm txheej, nws yuav maj mam decompose rau hauv dej thiab oxygen, tab sis tus nqi decomposition yog qeeb heev. Txoj hauv kev ceev nrawm rau cov tshuaj tiv thaiv yog ntxiv cov nplaim hluav taws xob-manganese dioxide, thiab lwm yam los yog irradiate nws nrog luv hluav taws xob. Muaj oxidation thiab txo qis hauv cov xwm txheej sib txawv. Siv nyob rau hauv kev yees duab stain remover; xiav thinning ntawm cov xim zoo zaj duab xis; super-proportional thinning ntawm zaj duab xis, thiab lwm yam Yooj yim kho kom zoo, tsis yooj yim kom khaws ntev. Lub Kaum Hlis 27, 2017, cov npe ntawm cov carcinogens tau tshaj tawm los ntawm Lub Koom Haum International rau Kev Tshawb Fawb Kab Mob Cancer ntawm Lub Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv Hauv Ntiaj Teb tau raug pib suav sau cia. Hydrogen peroxide muaj nyob rau hauv cov npe ntawm peb hom carcinogens.
