I-DMDM hydantoin iyinto emhlophe engenaphunga, ekristalu esebenza njengesithako sokulwa namagciwane kanye nesilondolozi ezimonyweni nasezikhiqizweni zokunakekela umuntu. Lo mkhiqizo unombala ophuzi ocacile. Uncibilika kalula emanzini, utshwala, i-glycol, futhi uzinzile esigabeni samanzi kanye nesisombululo samanzi samafutha. Ungahlala uzinzile ku--10~50℃, PH 6.5~8.5 unyaka owodwa.

Izinyanga eziyi-12
Isitoreji
ngaphansi kwezimo ezimnyama, ezomile, nezivaliwe, umlilo ukuvimbela.
I-DMDM hydantoin iyisivikelo ezimonyweni nasezintweni zokunakekelwa komuntu siqu. Isebenza ngokunciphisa nokuvimbela ukonakala emikhiqizweni efana nama-shampoo kanye nezimonyo zezinwele, kanye nasemikhiqizweni yokunakekelwa kwesikhumba efana nama-moisturizer kanye nezisekelo zezimonyo. I-DMDM hydantoin futhi iyi-ejenti yokulwa namagciwane esetshenziswa ezimonyweni nasezintweni zokunakekelwa komuntu siqu. Njenge-antimicrobial, ingasiza ekuvimbeleni ukukhula kwesikhunta, imvubelo kanye namagciwane ayingozi angenza abantu bagule noma abanike ama-rashes, isibonelo. I-DMDM hydantoin "ingumnikeli we-formaldehyde," okusho ukuthi ukuze isebenze njengesivikelo kanye nesivikelo, ikhipha amazinga amancane e-formaldehyde kuyo yonke impilo yeshelufu yomkhiqizo wokunakekelwa komuntu siqu noma umkhiqizo wezimonyo. Ngokusho kwe-Personal Care Products Council, izivikelo ezifana ne-DMDM hydantoin "ezikhipha kancane kancane amanani amancane, aphephile e-formaldehyde ngokuhamba kwesikhathi" zisiza ekuvimbeleni isikhunta namagciwane ayingozi. Ukuhlolwa kokuphepha kwakamuva okushicilelwe kuyi-International Journal of Toxicology kuqinisekisile ukuthi i-formaldehyde ingasetshenziswa ngokuphephile ezimonyweni uma imingcele yokuphepha emisiwe ingadluli. I-Cosmetics Directive ye-European Union iphinde yagunyaza i-DMDM hydantoin njengesivikelo ezimonyweni nasezikhiqizweni zokunakekelwa komuntu siqu ngenani eliphezulu lamaphesenti angu-0.6. I-DMDMH iyancibilika emanzini ngokukhululeka. Ingangezwa ku-ejenti yokuguqula ukhilimu noma ezingxenyeni ezihlanganisa i-emulsifying ze-coating. I-DMDMH ihambisana kahle ne-cation, i-anion kanye ne-ejenti esebenzayo ebusweni obungeyona i-ionic, i-emulsifier kanye neprotheni. Ukuhlolwa kubonisiwe, ingagcina umsebenzi wokulwa namagciwane ebangeni elikhulu le-PH kanye nokushisa isikhathi eside. Ingavimbela ngempumelelo ukukhula kwe-Gram-positive becterium, i-Gram-negative bacterium, imvubelo kanye ne-mildew. Isilinganiso esinconyiwe: 0.1~0.3, izinga lokushisa: ngaphansi kwama-50℃.
