DMDM Hydantoin yog cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej. Nws ua haujlwm los ntawm kev tshem tawm qeeb thiab tiv thaiv kev piam sij hauv cov khoom xws li cov tshuaj lom thiab cov plaub hau txias, thiab hauv cov khoom lag luam ntawm tawv nqaij xws li moisturizers thiab floup foundations. DMDM Hydantoin tseem yog antimicrobial siv hauv cov tshuaj pleev ib ce thiab cov khoom saib xyuas tus kheej. Raws li cov antimicrobial, nws tuaj yeem pab tiv thaiv kev loj hlob ntawm fungi, poov xab thiab cov kab mob ua phem uas tuaj yeem ua rau tib neeg mob pob txha, piv txwv. DMDM Hydantoin yog "formaldehyde pub dawb," uas yog qhov ua haujlwm ntawm formaldehyde thoob plaws lub txee lossis cov khoom lag luam zoo. Raws li tus neeg saib xyuas tus kheej, cov tshuaj tiv thaiv tus kheej xws li DMDM Hydantoin uas "maj mam tso me me, muaj kev nyab xeeb ntawm formaldehyde nyob rau lub sijhawm" pab tiv thaiv pwm pwm thiab cov kab mob. Kev ntsuas kev nyab xeeb tshiab tsis ntev los no luam tawm hauv Toxicology reffirfe uas tau siv cov tshuaj pleev ib ce yog tias tsim kev nyab xeeb kev nyab xeeb tsis dhau. Cov tshuaj pleev ib ce tshuaj pleev ib pab European ntawm European Union kuj tau pom zoo DMDM Hydantoin ua cov tshuaj pleev ib ce thiab cov khoom saib xyuas tus kheej ntawm 0.6 feem pua hauv qab dej dawb. Nws tuaj yeem raug ntxiv rau cov tshuaj ntsuab cream hloov kho lossis cov emulsifying cov khoom siv ntawm txheej. DMDMH muaj lub zog sib xyaw nrog cation, anion thiab noionic saum toj tus neeg sawv cev, emulsifier tus neeg sawv cev sab nrauv thiab cov protein. Kuaj tau ua pov thawj, nws tuaj yeem khaws cov haujlwm tshuaj tua kab mob hauv cov ntau ntawm PH thiab kub tau ntev. Nws tuaj yeem txwv txoj kev loj hlob ntawm gram-muaj becterium, gram-tsis zoo tus kab mob, poov xab thiab mildew. Kev Pom Zoo Txog Dosage: 0.1 ~ 0.3, Kub: Hauv 50 ℃.
