Le mveliso yi-55% yesisombululo se-DMDMH samanzi, usebenzisa ifomyula yemveliso yamazwe ngamazwe kunye nobuchwepheshe. Ukulawulwa ngokungqongqo ngabasebenzi bezobuchwepheshe obuphezulu beziko le-R & D, umgangatho unokwethenjelwa, ukuhambelana kakuhle, kwaye umphumo uhlala ixesha elide ngaphandle kokuchaphazela imveliso Ukubonakala, ukuvumba kunye nokusebenza. Ikhuselekile kwaye ayinayo ityhefu. Ingasetyenziswa kuluhlu olubanzi lwe-PH=5-12. Ihlamba, i-emulsion Yinto efanelekileyo ye-antiseptic kunye ne-antibacterial agent ye-cosmetics efana ne-cream, njl.
Uphawu Ukusebenza okuphezulu, i-fungicide yexabiso eliphantsi, kulula ukuyisebenzisa, i-soluble ngokulula emanzini kunye ne-alcohols ephantsi, kwaye izinzile kwi-emulsions yesigaba samanzi kunye ne-oyile. Iyahambelana ne-cationic, i-anionic kunye ne-nonionic surfactants, i-emulsifiers kunye neeprotheni. Izinzile ngokuhamba kwexesha, i-pH ebanzi kunye noluhlu lobushushu.
Usetyenziso olucetyisiweyo Ngenxa yokunyibilika kwayo okukodwa kwamanzi, i-DMDMH inokongezwa kwiikhrimu kunye nokuhlamba izinto zokunakekelwa komntu kunye noxinzelelo lwe-0.2 ~ 0.6%. Ukuba i-DMDMH yongezwa kwi-surfactant, ubushushu bayo buqhele ukuba yi-50℃~60℃, kwaye i-pH ikuluhlu lwe-7.5~8.5. Njengoko izithako kunye nokuqulunqwa kweemveliso zokunyamekela komntu zihluka kakhulu, ezinokuchaphazela ukusebenza kokugcinwa kwezinto, sincoma kakhulu ukuba uqinisekise ukusebenza kunye nokuzinza kwe-DMDMH ngaphambi kokuveliswa.
