He matū tiaki te DMDM hydantoin i roto i ngā mea whakapaipai me ngā hua tiaki whaiaro. Ka mahi mā te whakaroa me te ārai i te pirau o ngā hua pēnei i te shampoo me ngā whakangawari makawe, me ngā hua tiaki kiri pēnei i te hinu whakamakuku me ngā mea whakapaipai. He matū patu huakita anō hoki te DMDM hydantoin e whakamahia ana i roto i ngā mea whakapaipai me ngā hua tiaki whaiaro. Hei matū patu huakita, ka taea e ia te āwhina ki te ārai i te tipu o te harore, te rewena me ngā huakita kino ka taea te whakapōrearea i te tangata, te hoatu rānei i ngā ponana ki a rātou, hei tauira. Ko te DMDM hydantoin he "kaituku formaldehyde," ko te tikanga kia mahi hei matū tiaki me te patu huakita, ka tukuna e ia he iti o te formaldehyde puta noa i te wā e ora ana te hua tiaki whaiaro, te hua whakapaipai rānei. E ai ki te Kaunihera Hua Tiaki Whaiaro, ko ngā matū tiaki pēnei i te DMDM hydantoin e "tuku āta ana i ngā rahinga iti, haumaru o te formaldehyde i roto i te wā" ka āwhina ki te ārai i te harore me ngā huakita kino. I whakaūhia e tētahi aromatawai haumaru tata nei i whakaputaina i roto i te International Journal of Toxicology ka taea te whakamahi haumaru i te formaldehyde i roto i ngā mea whakapaipai mena kāore e hipa i ngā rohe haumaru kua whakaritea. Kua whakaaetia hoki e te Ture Whakapaipai o te Kotahitanga o Ūropi te DMDM hydantoin hei matū tiaki i roto i ngā whakapaipai me ngā hua tiaki whaiaro i te kukū mōrahi o te 0.6 ōrau. Ka taea te wairewa noa i roto i te wai te DMDMH. Ka taea te tāpiri atu ki te kaihoko whakarerekē kirīmi, ki ngā wāhanga emulsifying rānei o te paninga. He kaha te hototahi o te DMDMH ki te cation, anion me te kaihoko mata kore-ionic, te kaihoko emulsifier me te pūmua. Kua whakamātauhia, ka taea e ia te pupuri i te mahi antibacterial i roto i te whānuitanga o te PH me te pāmahana mō te wā roa. Ka taea e ia te aukati i te tipu o te Gram-positive becterium, te Gram-negative bacterium, te rewena me te harore. Te horopeta kua tūtohutia: 0.1~0.3, te pāmahana: i raro i te 50℃.
