I-DMDM hydantoin yinto emhlophe engenavumba, ekristale esebenza njenge-antimicrobial agent kunye ne-preservative kwizithambiso nakwimveliso zokhathalelo lomntu. Le mveliso inombala otyheli ocacileyo. Inyibilika lula emanzini, kwi-alcohol, kwi-glycol, kwaye izinzile kwi-aqueors phase kunye nesisombululo samanzi seoyile. Inokuhlala izinzile kwi--10~50℃, PH 6.5~8.5 unyaka omnye.

phantsi kweemeko ezimnyama, ezomileyo, nezivaliweyo, umlilo ukuthintela.
I-DMDM hydantoin sisigcina-zimonyo kwiimveliso zokuthambisa kunye nezokhathalelo lomntu. Isebenza ngokunciphisa nokuthintela ukonakala kwiimveliso ezifana neeshampu kunye nezilungisi zeenwele, nakwiimveliso zokhathalelo lolusu ezifana nezithambisi-manzi kunye neziseko zokuthambisa. I-DMDM hydantoin ikwasisithambisi sokulwa neentsholongwane esisetyenziswa kwiimveliso zokuthambisa kunye nezokhathalelo lomntu. Njengesibulala-zimonyo, inokunceda ekuthinteleni ukukhula kwefungi, igwele kunye neebhaktheriya eziyingozi ezinokubangela abantu bagule okanye zibanike amabala, umzekelo. I-DMDM hydantoin "ngumnikeli we-formaldehyde," oko kuthetha ukuba ukuze isebenze njengesigcina-zimonyo kunye nesibulala-zimonyo, ikhupha amanqanaba amancinci e-formaldehyde kuyo yonke ixesha leshelufu yemveliso yokhathalelo lomntu okanye imveliso yokuthambisa. Ngokutsho kweBhunga leeMveliso zoKhathalelo lomntu, izigcina-zimonyo ezifana ne-DMDM hydantoin "ezikhupha kancinci ubungakanani obuncinci, obukhuselekileyo be-formaldehyde ngokuhamba kwexesha" zinceda ekuthinteleni ukungunda kunye neebhaktheriya eziyingozi. Uvavanyo lwakutshanje lokhuseleko olupapashwe kwi-International Journal of Toxicology luqinisekisile kwakhona ukuba i-formaldehyde ingasetyenziswa ngokukhuselekileyo kwiimveliso zokuthambisa ukuba imida yokhuseleko emiselweyo ayidluli. I-Cosmetics Directive ye-European Union ikwavumile i-DMDM hydantoin njengesigcini kwizithambiso nakwimveliso zokhathalelo lomntu kumlinganiselo ophezulu we-0.6%. I-DMDMH iyanyibilika emanzini ngokukhululekileyo. Ingongezwa kwi-cream modifier agent okanye kwi-emulsifying components ye-coating. I-DMDMH ihambelana kakhulu ne-cation, i-anion kunye ne-nonionic surface active agent, i-emulsifier agent kunye neproteni. Uvavanyo lubonisiwe, inokugcina umsebenzi we-antibacterial kuluhlu olukhulu lwe-PH kunye nobushushu ixesha elide. Ingathintela ngempumelelo ukukhula kwe-Gram-positive becterium, i-Gram-negative bacterium, i-yeast kunye ne-mildew. Umthamo onconywayo: 0.1~0.3, ubushushu: ngaphantsi kwe-50℃.
