DM DM hydantoin yog ib qho tshuaj khaws cia hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej.Nws ua haujlwm los ntawm kev qeeb thiab tiv thaiv kev lwj hauv cov khoom xws li tshuaj zawv plaub hau thiab cov plaub hau txias, thiab hauv cov khoom tu tawv nqaij xws li moisturizers thiab pleev cov hauv paus.DMDM hydantoin kuj yog ib qho tshuaj tua kab mob uas siv rau hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej.Raws li cov tshuaj tua kab mob, nws tuaj yeem pab tiv thaiv kev loj hlob ntawm cov kab mob fungi, cov poov xab thiab cov kab mob tsis zoo uas tuaj yeem ua rau tib neeg mob lossis ua rau pob liab liab, piv txwv li.DMDM hydantoin yog "formaldehyde pub," uas txhais tau hais tias ua haujlwm raws li kev khaws cia thiab tshuaj tua kab mob, nws tso tawm me me ntawm formaldehyde thoob plaws hauv txee-lub neej ntawm cov khoom tu tus kheej lossis cov khoom siv tshuaj pleev ib ce.Raws li Pawg Saib Xyuas Kev Noj Qab Haus Huv Tus Kheej, cov tshuaj tiv thaiv xws li DMDM hydantoin uas "tso maj mam tso me me, muaj kev nyab xeeb ntawm formaldehyde dhau sijhawm" pab tiv thaiv pwm thiab kab mob.Kev ntsuam xyuas kev nyab xeeb tsis ntev los no tau tshaj tawm hauv International Journal of Toxicology rov lees paub tias formaldehyde tuaj yeem siv tau zoo hauv cov tshuaj pleev ib ce yog tias tsim muaj kev txwv tsis pub dhau.Lub Cosmetics Directive ntawm European Union kuj tau pom zoo DMDM hydantoin raws li kev khaws cia hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej ntawm qhov siab tshaj plaws ntawm 0.6 feem pua.DMDMH yog soluble hauv dej dawb.Nws tuaj yeem muab ntxiv rau tus neeg sawv cev hloov kho cream lossis emulsifying Cheebtsam ntawm txheej.DMDMH muaj kev sib raug zoo nrog cation, anion thiab nonionic nto active tus neeg saib xyuas, emulsifier tus neeg saib xyuas thiab cov protein.Kev sim ua pov thawj, nws tuaj yeem khaws cov tshuaj tua kab mob hauv ntau yam ntawm PH thiab kub rau lub sijhawm ntev.Nws tuaj yeem txwv kev loj hlob ntawm Gram-possitive becterium, Gram-negative kab mob, poov xab thiab mildew.Kev pom zoo ntau npaum: 0.1 ~ 0.3, kub: hauv qab 50 ℃.
