Hydantoin ya DMDM ni ikintu cy'umweru kitagira impumuro, gikozwe mu buryo bwa kristu, gikora nk'umuti urwanya udukoko no kubungabunga ibidukikije mu mavuta yo kwisiga no mu bikoresho byo kwisiga. Iki gicuruzwa ni umuhondo ugaragara neza. Gishongeshwa byoroshye mu mazi, alcool, glycol, kandi kikaba gihamye mu mazi no mu gikoresho cy'amavuta. Gishobora kuguma gihamye mu gihe cy'umwaka umwe hagati ya -10 ~ 50℃, PH 6.5 ~ 8.5.

DMDM hydantoin ni umuti urinda kwangirika mu mavuta yo kwisiga no mu bikoresho byo kwisiga. Ikora mu kugabanya no gukumira kwangirika mu bikoresho nka shampoo na conditioner zo mu musatsi, no mu bikoresho byo kwisiga nk'ibinyabutabire n'ibikomoka ku kwisiga. DMDM hydantoin ni umuti urwanya udukoko ukoreshwa mu mavuta yo kwisiga no mu bikoresho byo kwisiga. Nk'umuti urwanya udukoko, ushobora gufasha mu gukumira gukura kw'ibihumyo, umusemburo na bagiteri zangiza zishobora gutera abantu indwara cyangwa zikabatera uduheri, urugero. DMDM hydantoin ni "umutanga formaldehyde," bivuze ko kugira ngo ikore nk'umuti urinda kwangirika no kurwanya udukoko, isohora ingano nto ya formaldehyde mu gihe cyose ibicuruzwa byo kwisiga cyangwa ibikoresho byo kwisiga bimara. Nk'uko Inama y'Ibicuruzwa byo Kwisiga ibivuga, imiti irinda kwangirika nka DMDM hydantoin "isohora buhoro buhoro formaldehyde nto kandi yizewe uko igihe kigenda gihita" ifasha mu gukumira ibihumyo na bagiteri byangiza. Isuzuma riherutse gukorwa mu kinyamakuru Mpuzamahanga cy'Uburyo bwo Kwisiga ryashimangiye ko formaldehyde ishobora gukoreshwa mu buryo bwizewe mu mavuta yo kwisiga niba nta ngero z'umutekano zashyizweho zitarenze. Amabwiriza y’Ubumwe bw’u Burayi ku bijyanye n’ubwiza bw’umubiri (cosmetics) yemeje kandi ko DMDM hydantoin ari ikintu kiyirinda kwangirika mu mavuta yo kwisiga no mu bikoresho by’ubwisungane ku kigero ntarengwa cya 0.6%. DMDMH ishongeshwa mu mazi ku buryo bworoshye. Ishobora kongerwa mu kintu gihindura amavuta cyangwa mu bice biyisiga. DMDMH ikorana neza na cation, anion na nonionic surface active agent, emulsifier agent na poroteyine. Byagaragaye ko ishobora kugumana imikorere ya antibacterial mu rugero rwa pH n’ubushyuhe bwinshi igihe kirekire. Ishobora kugabanya cyane ubwiyongere bwa Gram-positive becterium, Gram-negative bacterium, imisemburo na mildew. Igipimo cyatanzwe ni: 0.1 ~ 0.3, ubushyuhe: munsi ya 50℃.
