I-DMDM hydantoin yinto emhlophe engenavumba, eyikristale esebenza njenge-antimicrobial agent kunye ne-preservative kwizithambiso kunye neemveliso zokhathalelo lomntu.Imveliso i-Transparent yellowish.Inyibilika ngokulula emanzini, etywaleni, kwi-glycol, kwaye izinzile kwisigaba se-aqueors kunye nesisombululo samanzi seoli.Inokuhlala izinzile kwi -10 ~ 50℃, PH 6.5 ~ 8.5 unyaka omnye.

Ugcino
phantsi komthunzi, ukoma, kunye neemeko ezivaliweyo, umlilo uthintelo.
I-DMDM hydantoin sisilondolozi kwizithambiso kunye neemveliso zokhathalelo lomntu.Isebenza ngokucotha kunye nokuthintela ukubola kwiimveliso ezifana neshampu kunye nezilungisi zeenwele, kunye neemveliso zokhathalelo lwesikhumba ezifana nezinto zokuthambisa kunye neziseko zokuthambisa.I-DMDM hydantoin ikwayi-agent ye-antimicrobial esetyenziswa kwizithambiso kunye neemveliso zokhathalelo lomntu.Njenge-antimicrobial, inokunceda ukukhusela ukukhula kwefungi, imvubelo kunye neebhaktheriya ezinobungozi ezinokuthi zigule abantu okanye zibanike i-rashes, umzekelo.I-DMDM hydantoin “yi-formaldehyde donor,” nto leyo ethetha ukuba ukusebenza njengento egcinayo kunye ne-antimicrobial, ikhupha amanqanaba amancinci e-formaldehyde kuyo yonke ishelufu yobomi bemveliso yokhathalelo lomntu okanye imveliso yokuthambisa.Ngokutsho kweBhunga leeMveliso zoMntu, izilondolozo ezifana ne-DMDM hydantoin ethi "ikhupha ngokukhawuleza, imilinganiselo ekhuselekileyo ye-formaldehyde ekuhambeni kwexesha" inceda ukukhusela isikhunta esiyingozi kunye neebhaktheriya.Uvavanyo lwamva nje lokhuseleko olupapashwe kwi-International Journal of Toxicology luqinisekisile ukuba i-formaldehyde ingasetyenziswa ngokukhuselekileyo kwizinto zokuthambisa ukuba imida yokhuseleko emiselweyo ayigqithiswanga.I-Cosmetics Directive ye-European Union iphinde ivume i-DMDM i-hydantoin njengento yokukhusela kwizinto zokuthambisa kunye neemveliso zokunyamekela komntu kwi-concentration enkulu ye-0.6 yeepesenti.I-DMDMH iyanyibilika emanzini ngokukhululekile.Inokongezwa kwi-agent yokuguqula i-cream okanye i-emulsifying components of coating.I-DMDMH inokuhambelana okuqinileyo kunye ne-cation, i-anion kunye ne-nonionic surface esebenzayo, i-emulsifier agent kunye neprotheni.Uvavanyo luqinisekisiwe, lunokugcina umsebenzi we-antibacterial kuluhlu olukhulu lwe-PH kunye nobushushu ixesha elide.Inokuthintela ngokufanelekileyo ukukhula kwe-Gram-positive becterium, i-Gram-negative bacterium, igwele kunye nokungunda.Idosi enconyiweyo: 0.1 ~ 0.3, ubushushu: ngaphantsi kwe-50 ℃.
