ʻO DMDM hydantoin kahi mea mālama i nā mea hoʻonaninani a me nā huahana mālama pilikino.Hana ia ma ka lohi a pale ʻana i ka palaho i nā huahana e like me nā shampoos a me nā mea hoʻomaʻemaʻe lauoho, a me nā huahana mālama ʻili e like me nā moisturizers a me nā kumu hoʻonaninani.ʻO DMDM hydantoin kekahi mea antimicrobial i hoʻohana ʻia i nā mea hoʻonaninani a me nā huahana mālama pilikino.Ma ke ʻano he antimicrobial, hiki iā ia ke kōkua i ka pale ʻana i ka ulu ʻana o nā haʻiki, hū a me nā maʻi maʻi ʻino e hiki ai i ka poʻe ke maʻi a hāʻawi paha iā lākou i nā ʻōpala, no ka laʻana.ʻO ka DMDM hydantoin he "mea hāʻawi formaldehyde," ʻo ia hoʻi e hana ma ke ʻano he preservative a antimicrobial, hoʻokuʻu ʻo ia i nā pae liʻiliʻi o ka formaldehyde i loko o ke ola o kahi huahana mālama pilikino a i ʻole nā mea hoʻonaninani.Wahi a ka Personal Care Products Council, nā mea mālama e like me DMDM hydantoin e "hoʻokuʻu mālie i nā formaldehyde liʻiliʻi a palekana i ka manawa" kōkua i ka pale ʻana i ka pōʻino a me ka bacteria.Ua hōʻoia hou ʻia kahi loiloi palekana hou i paʻi ʻia ma ka International Journal of Toxicology e hiki ke hoʻohana pono ʻia ka formaldehyde i nā mea hoʻonaninani inā ʻaʻole i ʻoi aku ka nui o nā palena palekana.Ua ʻae pū ka Cosmetics Directive o ka European Union i ka DMDM hydantoin ma ke ʻano he preservative i nā mea hoʻonaninani a me nā huahana mālama pilikino ma kahi kiʻekiʻe o 0.6 pakeneka. Hiki ke hoʻoheheʻe ʻia ka DMDMH i ka wai manuahi.Hiki ke hoʻohui ʻia i ka mea hoʻololi cream a i ʻole nā mea emulsifying o ka uhi.Loaʻa i ka DMDMH ka hoʻohālikelike ikaika me ka cation, anion a me ka nonionic surface active agent, emulsifier agent a me ka protein.Hōʻike ʻia ka hoʻāʻo, hiki iā ia ke mālama i ka hana antibacterial i ka nui o ka PH a me ka mahana no ka manawa lōʻihi.Hiki iā ia ke kāohi pono i ka ulu ʻana o Gram-possitive becterium, Gram-negative bacteria, yeasts a me ka malili.Hoʻohanohano ʻia: 0.1 ~ 0.3, mahana: ma lalo o 50 ℃.
