I-Dmdm hydantoin iyinto emhlophe ye-Dmdy, i-crystalline esebenza njenge-ejenti ye-antimicrobial kanye nokulondolozwa kwezimonyo kanye nemikhiqizo yokunakekelwa komuntu siqu. Ichithwa kalula emanzini, utshwala, i-glycol, futhi igxile esigabeni se-aqueors kanye nesixazululo samafutha kawoyela. Kungenzeka ihlale iqinile ku -10 ~ 50 ℃, pH 6.5 ~ 8.5 ngonyaka owodwa.

Ukubeka
ngaphansi komthunzi, omile, futhi ovaliwe, umlilo Ukuvimbela.
I-Dmdm hydantoin iyindlela yokugcina yezimonyo kanye nemikhiqizo yokunakekelwa komuntu siqu. Isebenza ngokunciphisa futhi ivimbela ukonakala kwemikhiqizo efana nama-shampoos kanye nama-hair conditioners, kanye nemikhiqizo yokunakekelwa kwesikhumba efana ne-moisturizer kanye nezilungiselelo zokwenza izikewu. I-Dmdm hydantoin futhi i-ajenti ye-antimicrobial esetshenziswe kwizimonyo kanye nemikhiqizo yokunakekelwa komuntu siqu. Njenge-antimicrobial, kungasiza ukuvikela ukukhula kwesikhunta, imvubelo kanye namagciwane ayingozi angenza abantu bagule noma bawanikeze ama-rashes, ngokwesibonelo. I-Dmdm hydantoin ingumuntu "i-formaldehyde onikelayo," okusho ukuthi ukusebenza njengendlela yokugcina kanye ne-antimicrobial, ikhipha amazinga amancane we-formaldehyde kulo lonke elaseshalofini noma umkhiqizo wezimonyo. Ngokusho koMkhandlu Wemikhiqizo Yezokunakekelwa Kwabodwa, okulondolozwa njenge-DMDM Hydantoin "ededela kancane kancane, amanani aphephile we-formaldehyde ngokuhamba kwesikhathi" asiza ukuvimbela isikhunta esilimazayo namagciwane. Ukuhlolwa kwakamuva kwezokuphepha okushicilelwe ku-International Journal of Toxicology Reaffd ukuthi i-formaldehyde ingasetshenziswa ngokuphepha ezimotweni uma imikhawulo yokuphepha esungulwe ayidluli. Umyalelo wezimonyo ze-European Union futhi ugunyaze i-DMDM Hydantoin njengendawo yokugcina yezimonyo kanye nemikhiqizo yokunakekelwa komuntu siqu ngokuqoqwa okuphezulu kwamaphesenti angama-0.6 %.dmdmh kuyancibilika emanzini ngokukhululeka. Ingangezwa ku-ukhilimu okuguqula i-ejenti noma izingxenye ezimangazayo zokuhlanganisa. I-Dmdmh inokuhambisana okuqinile nge-cation, anion ne-agent esebenzayo ye-nonion esebenzayo, i-ejenti ye-emulsifier kanye namaprotheni. Ukuhlolwa kufakazelwe, kungagcina umsebenzi we-antibacterial uhla olukhulu lwe-pH kanye lokushisa isikhathi eside. Ingaphoqa ngempumelelo ukukhula kwe-gram-passive Becturium, i-bacterium ebiyelwe i-gram, imvubelo kanye nesikhutha. Umthamo owenziwe: 0.1 ~ 0.3, izinga lokushisa: ngaphansi kwama-50 ℃.
