DMDM hydantoin ndi mankhwala osungira mu zodzoladzola ndi zosamalira munthu.Zimagwira ntchito pochepetsa komanso kupewa kuwonongeka kwa zinthu monga ma shampoos ndi zowongolera tsitsi, komanso pazinthu zosamalira khungu monga zonyowa ndi zopakapaka.DMDM hydantoin ndi mankhwala ophera tizilombo toyambitsa matenda omwe amagwiritsidwa ntchito mu zodzoladzola ndi zinthu zosamalira anthu.Monga antimicrobial, zingathandize kupewa kukula kwa bowa, yisiti ndi mabakiteriya owopsa omwe amatha kudwalitsa anthu kapena kuwapatsa zotupa, mwachitsanzo.DMDM hydantoin ndi "formaldehyde donor," kutanthauza kuti kugwira ntchito ngati mankhwala oteteza komanso antimicrobial, imatulutsa timagulu tating'ono ta formaldehyde panthawi yonse ya alumali ya mankhwala osamalira munthu kapena mankhwala odzola.Malinga ndi Personal Care Products Council, zoteteza monga DMDM hydantoin zomwe "zimatulutsa pang'onopang'ono tinthu tating'ono ta formaldehyde pakapita nthawi" zimathandiza kupewa nkhungu ndi mabakiteriya owopsa.Kuwunika kwaposachedwa kwachitetezo komwe kudasindikizidwa mu International Journal of Toxicology kunatsimikiziranso kuti formaldehyde itha kugwiritsidwa ntchito mosamala mu zodzoladzola ngati malire otetezedwa sadutsa.Cosmetics Directive ya European Union yavomerezanso DMDM hydantoin ngati chosungira mu zodzoladzola ndi zinthu zosamalira munthu pamlingo waukulu wa 0.6 peresenti.DMDMH imasungunuka m'madzi momasuka.Ikhoza kuwonjezeredwa ku zonona zonona zonona kapena zigawo za emulsifying za zokutira.DMDMH imagwirizana kwambiri ndi cation, anion ndi nonionic pamwamba yogwira ntchito, emulsifier agent ndi mapuloteni.Kuyesedwa kwatsimikiziridwa, kumatha kusunga zochita za antibacterial mumitundu yayikulu ya PH ndi kutentha kwa nthawi yayitali.Ikhoza kulepheretsa kukula kwa Gram-positive becterium, Gram-negative bacteria, yisiti ndi mildew.Mlingo wovomerezeka: 0.1 ~ 0.3, kutentha: pansi pa 50 ℃.
