Hydrogen peroxide tsis ruaj khov thiab yooj yim decomposes rau hauv oxygen thiab dej, uas muaj kev nyab xeeb zoo los ntawm qhov no. Cov kev tshawb fawb tau lees paub tias hydrogen peroxide residue nyob rau hauv cov khoom uas soaked nrog dej yuav maj decompose thiab ploj thaum lub sij hawm soaking txheej txheem, thiab tom qab ua hauj lwm yuav sai sai rhuav tshem nws thiab.
Xyoo 2004, Pawg Kws Tshaj Lij ntawm Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb (JECFA) tau soj ntsuam tias hydrogen peroxide residues hauv cov zaub mov muaj tsawg heev uas thaum lub sij hawm cov neeg siv khoom noj, nws tau degraded yuav luag txog qhov tsis muaj kev txhawj xeeb, yog li tsis muaj kev xav tau. tsim kom muaj "safe intake".
Lub US Food and Drug Administration tseem faib cov hydrogen peroxide li GRAS (piv txwv li, muaj kev nyab xeeb zoo) thiab feem ntau yog siv raws li qhov xav tau rau kev tsim khoom (piv txwv li, kev siv tsis txwv). Piv txwv li, qhov siab tshaj plaws siv hauv cov ntses xiav thiab cov qe qe yog "kom ua tiav oxidation thiab cov kab mob tua kab mob", thiab qhov siab tshaj plaws uas siv rau hauv kev ua tripe yog "kom ua tiav cov nyhuv bleaching". Tsis tas li ntawd, hydrogen peroxide kuj tuaj yeem siv los ntxuav thiab tua kab mob txiv hmab txiv ntoo thiab zaub.
Kev kho mob hydrogen peroxide nrog rau qhov siab ntawm 3 feem pua feem ntau tsis yog qhov teeb meem loj txawm tias nws tau ua yuam kev. Tab sis yog tias hydrogen peroxide nrog ib qho concentration ntawm 30 feem pua yog qaug cawv ncaj qha, nws tuaj yeem hlawv lub plab zom mov.Txawm li cas los xij, qhov no tsis tshua muaj vim tias tus neeg nruab nrab tsis tuaj yeem ntsib nrog cov concentration ntawm hydrogen peroxide.
Tsis tas li ntawd, hydrogen peroxide tuaj yeem tawg sai sai hauv cov ntsev hlau hnyav, alkaline ib puag ncig thiab muaj kev cuam tshuam hnyav, thiab tseem ua rau tawg. Qhov no feem ntau tshwm sim thaum lub sijhawm tsim khoom, khaws cia thiab kev thauj mus los ntawm hydrogen peroxide thiab tsis zoo li yuav ntsib los ntawm cov neeg siv khoom.
