I-DMDM hydantoin iwuketshezi olumhlophe olunganuki, oluyikristalu olusebenza njenge-ejenti elwa namagciwane futhi lulondoloza izimonyo nemikhiqizo yokunakekela umuntu.Umkhiqizo unombala ophuzi obala.Incibilika kalula emanzini, otshwaleni, ku-glycol, futhi iqine esigabeni se-aqueors nesisombululo samanzi samafutha.Ingase ihlale iqinile kokuthi -10~50℃, PH 6.5~8.5 unyaka ongu-1.

ngaphansi kwezimo ezinomthunzi, ezomile, nezivaliwe, umlilo ukuvimbela.
I-DMDM hydantoin iyisilondolozi sezimonyo nemikhiqizo yokunakekela umuntu.Isebenza ngokunciphisa futhi ivimbele ukubola emikhiqizweni efana namashampoo nezimonyo zezinwele, nasemikhiqizweni yokunakekelwa kwesikhumba efana nezinto zokuthambisa kanye nezisekelo zokuziphaqula.I-DMDM hydantoin futhi iyi-ejenti elwa namagciwane esetshenziswa ezimonyoni nasezikhiqizweni zokunakekela umuntu.Njenge-antimicrobial, ingasiza ekuvimbeleni ukukhula kwesikhunta, imvubelo kanye namabhaktheriya ayingozi angenza abantu bagule noma banikeze ama-rashes, isibonelo.I-DMDM hydantoin “ingumnikeli we-formaldehyde,” okusho ukuthi ukuze isebenze njengesivikelo kanye ne-antimicrobial, ikhipha amazinga amancane e-formaldehyde kuyo yonke impilo yeshalofu yomkhiqizo wokunakekelwa komuntu siqu noma umkhiqizo wezimonyo.NgokoMkhandlu Wemikhiqizo Yokunakekelwa Komuntu Siqu, izivimbelakuvunda njenge-DMDM hydantoin “ezikhipha kancane kancane amanani aphephile e-formaldehyde ngokuhamba kwesikhathi” zisiza ukuvimbela isikhunta esiyingozi namagciwane.Ukuhlolwa kokuphepha kwakamuva okushicilelwe ku-International Journal of Toxicology kuphinde kwaqinisekisa ukuthi i-formaldehyde ingasetshenziswa ngokuphepha ezimonyoni uma imikhawulo yokuphepha emisiwe ingeqiwe.I-Cosmetics Directive ye-European Union iphinde yagunyaza i-DMDM hydantoin njengesilondolozi ezimonyoni nasezikhiqizweni zokunakekelwa komuntu siqu ekuhlanganiseni okuphezulu okungamaphesenti angu-0.6.I-DMDMH incibilika emanzini ngokukhululeka.Ingafakwa ku-agent yokuguqula ukhilimu noma izingxenye ze-emulsifying zokugqoka.I-DMDMH inokuhambisana okuqinile ne-cation, i-anion kanye ne-nonionic surface ejenti esebenzayo, i-emulsifier ejenti kanye nephrotheni.Ukuhlola kufakazelwe, kungagcina umsebenzi wokulwa namagciwane ebangeni elikhulu le-PH nezinga lokushisa isikhathi eside.Kungavimbela ngempumelelo ukukhula kwe-Gram-possitive becterium, i-Gram-negative bacterium, i-yeasts kanye nesikhunta.Umthamo onconyiwe: 0.1~0.3, izinga lokushisa: ngaphansi 50℃.
