He mea keʻokeʻo ʻala ʻole ka DMDM hydantoin, he mea aniani e hana ana ma ke ʻano he mea antimicrobial a me ka mea mālama i nā mea hoʻonani a me nā huahana mālama pilikino. He melemele moakaka ka huahana. Hoʻoheheʻe maʻalahi ia i ka wai, ka waiʻona, ka glycol, a paʻa i ka pae aqueors a me ka wai hoʻonā o ka aila. Hiki ke noho paʻa i ka -10 ~ 50 ℃, PH 6.5 ~ 8.5 no 1 makahiki.

He mea mālama ka DMDM hydantoin i nā mea hoʻonani a me nā huahana mālama pilikino. Hana ia ma ka hoʻolohi a me ka pale ʻana i ka palaho ʻana i nā huahana e like me nā shampoos a me nā mea hoʻomaʻemaʻe lauoho, a i nā huahana mālama ʻili e like me nā moisturizers a me nā kumu hoʻonaninani. He mea antimicrobial hoʻi ka DMDM hydantoin i hoʻohana ʻia i nā mea hoʻonani 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 fungi, hū a me nā bacteria ʻino e hiki ai ke hoʻomaʻi i nā kānaka a hāʻawi paha iā lākou i nā ʻulaʻula, no ka laʻana. ʻO DMDM hydantoin kahi "formaldehyde donor," ʻo ia hoʻi, no ka hana ʻana ma ke ʻano he mea mālama a me ka antimicrobial, hoʻokuʻu ia i nā pae liʻiliʻi o ka formaldehyde ma ke ola o kahi huahana mālama pilikino a huahana hoʻonani paha. Wahi a ka ʻAha Kūkākūkā o nā Huahana Mālama Pilikino, ʻo nā mea mālama e like me DMDM hydantoin e "hoʻokuʻu mālie ana i nā nui liʻiliʻi a palekana o ka formaldehyde i ka hala ʻana o ka manawa" e kōkua i ka pale ʻana i ka ʻōpala a me nā bacteria ʻino. Ua hōʻoia hou kahi loiloi palekana i paʻi ʻia ma ka International Journal of Toxicology hiki ke hoʻohana palekana ʻia ka formaldehyde i nā mea hoʻonani inā ʻaʻole i ʻoi aku nā palena palekana i hoʻokumu ʻia. Ua ʻāpono pū ka Cosmetics Directive o ka European Union i ka DMDM hydantoin ma ke ʻano he mea mālama i nā mea hoʻonani a me nā huahana mālama pilikino ma kahi kiʻekiʻe loa o 0.6 pakeneka. Hoʻoheheʻe manuahi ʻia ka DMDMH i ka wai. Hiki ke hoʻohui ʻia i ka mea hoʻololi kirīmi a i ʻole nā mea emulsifying o ka uhi ʻana. Loaʻa i ka DMDMH kahi kūlike ikaika me ka cation, anion a me ka nonionic surface active agent, emulsifier agent a me ka protein. Ua hōʻoia ʻia ka hoʻāʻo, hiki iā ia ke mālama i ka hana antibacterial ma kahi ākea o 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 bacterium, yeasts a me ka mildew. Dosis i ʻōlelo ʻia: 0.1 ~ 0.3, mahana: ma lalo o 50 ℃.
