DMDM hydantoin chinhu chinodzivirira muzvizoro nezvigadzirwa zvekuchengetedza muviri. Inoshanda nekuderedza kuora kweganda muzvigadzirwa zvakaita semashampoos nezvinogadzirisa bvudzi, uye muzvigadzirwa zvekuchengetedza ganda zvakaita sezvinyorovesa uye zvigadzirwa zvekuzora. DMDM hydantoin chinhu chinodzivirira utachiona chinoshandiswawo muzvizoro nezvigadzirwa zvekuchengetedza muviri. Semushonga unorwisa utachiona, unogona kubatsira kudzivirira kukura kwefungus, mbiriso uye mabhakitiriya anokuvadza anogona kurwarisa vanhu kana kuvapa mapundu, semuenzaniso. DMDM hydantoin "mupi weformaldehyde," zvinoreva kuti kuti ishande semushonga unochengetedza muviri uye unorwisa utachiona, inoburitsa huwandu hudiki hweformaldehyde mukati menguva yese yekuchengetedzwa kwemuviri kana chigadzirwa chekushongedza. Sekureva kwePersonal Care Products Council, zvinochengetedza zvakaita seDMDM hydantoin "zvinoburitsa zvishoma nezvishoma huwandu hudiki hweformaldehyde nekufamba kwenguva" zvinobatsira kudzivirira chakuvhuvhu nemabhakitiriya anokuvadza. Ongororo yazvino yekuchengetedzwa yakaburitswa muInternational Journal of Toxicology yakasimbisazve kuti formaldehyde inogona kushandiswa zvakachengeteka muzvizoro kana miganhu yekuchengetedza isina kupfuudzwa. Mutemo weCosmetics weEuropean Union wakabvumidzawo DMDM hydantoin semushonga unochengetedza muzvizoro nezvigadzirwa zvekuchengetedza muviri pahuwandu hwakanyanya hwe0.6 muzana. DMDMH inonyungudika mumvura zvakasununguka. Inogona kuwedzerwa kune inogadzirisa kirimu kana zvinhu zvinosanganisa kuputira. DMDMH inoenderana zvakasimba ne cation, anion uye nonionic surface active agent, emulsifier agent uye protein. Zvakaonekwa kuti inogona kuchengetedza basa remabhakitiriya munzvimbo yakakura yePH uye tembiricha kwenguva yakareba. Inogona kudzivirira kukura kweGram-possitive becterium, Gram-negative bacterium, yeast uye mildew. Chiyero chinorumbidzwa: 0.1~0.3, tembiricha: pasi pe50℃.
