DMDM hydantoin ndi chinthu choyera chopanda fungo, chomwe chimagwira ntchito ngati mankhwala ophera tizilombo toyambitsa matenda komanso chosungira zinthu zodzoladzola ndi zosamalira thupi. Chogulitsachi ndi chachikasu chowonekera bwino. Chimasungunuka mosavuta m'madzi, mowa, glycol, ndipo chimakhala chokhazikika mumadzi ndi madzi. Chingakhale chokhazikika mu -10~50℃, PH 6.5~8.5 kwa chaka chimodzi.

DMDM hydantoin ndi mankhwala osungira zinthu zodzoladzola ndi zinthu zosamalira thupi. Imagwira ntchito pochepetsa ndi kupewa kuwonongeka kwa zinthu monga shampu ndi zodzoladzola tsitsi, komanso zinthu zosamalira khungu monga zonyowetsa khungu ndi zodzoladzola. DMDM hydantoin ndi mankhwala ophera tizilombo omwe amagwiritsidwa ntchito mu zodzoladzola ndi zinthu zosamalira thupi. Monga mankhwala ophera tizilombo toyambitsa matenda, ingathandize kupewa kukula kwa bowa, yisiti ndi mabakiteriya owopsa omwe angapangitse anthu kudwala kapena kuwapangitsa kutupa, mwachitsanzo. DMDM hydantoin ndi "wopereka formaldehyde," zomwe zikutanthauza kuti kuti igwire ntchito ngati mankhwala osungira komanso ophera tizilombo toyambitsa matenda, imatulutsa formaldehyde yochepa nthawi yonse yomwe mankhwala osamalira thupi kapena zinthu zokongoletsa amakhala. Malinga ndi Personal Care Products Council, mankhwala osungira monga DMDM hydantoin omwe "amatulutsa pang'onopang'ono formaldehyde pang'onopang'ono pakapita nthawi" amathandiza kupewa nkhungu ndi mabakiteriya owopsa. Kuwunika kwaposachedwa kwachitetezo komwe kunafalitsidwa mu International Journal of Toxicology kunatsimikiziranso kuti formaldehyde ingagwiritsidwe ntchito mosamala mu zodzoladzola ngati malire okhazikika a chitetezo sadutsa. Lamulo la Zodzoladzola la European Union lavomerezanso DMDM hydantoin ngati chosungira mu zodzoladzola ndi zinthu zosamalira thupi pamlingo wapamwamba wa 0.6 peresenti. DMDMH imasungunuka m'madzi momasuka. Ikhoza kuwonjezeredwa ku chosinthira kirimu kapena zinthu zoyeretsera. DMDMH imagwirizana kwambiri ndi cation, anion ndi nonionic surface active agent, emulsifier agent ndi mapuloteni. Mayeso atsimikizira kuti imatha kusunga mphamvu ya mabakiteriya pamlingo waukulu wa PH ndi kutentha kwa nthawi yayitali. Imatha kuletsa kukula kwa Gram-positive becterium, Gram-negative bacterium, yisiti ndi mildew. Mlingo wovomerezeka: 0.1~0.3, kutentha: pansi pa 50℃.
