Cov khoom no yog 55% DMDMH aqueous solution, siv cov mis tsim khoom thoob ntiaj teb tshiab thiab thev naus laus zis. Tswj hwm nruj los ntawm cov neeg ua haujlwm siab ntawm R & D center, qhov zoo yog txhim khu kev qha, kev sib raug zoo yog qhov zoo, thiab cov nyhuv yog ntev tsis cuam tshuam rau cov khoom tsos, tsw thiab kev ua tau zoo. Nws muaj kev nyab xeeb thiab tsis muaj tshuaj lom. Nws tuaj yeem siv rau ntau yam PH = 5-12. Nws yog ntxuav, emulsion Nws yog ib qho tshuaj tua kab mob thiab tshuaj tua kab mob zoo tagnrho rau cov tshuaj pleev ib ce xws li, tshuaj pleev ib ce, thiab lwm yam.
Yam ntxwv Tshuaj tua kab mob ua haujlwm tau zoo, pheej yig, yooj yim siv, yooj yim yaj hauv dej thiab cov cawv qis dua, thiab ruaj khov hauv cov dej thiab cov roj emulsions. Nws sib xws nrog cationic, anionic thiab nonionic surfactants, emulsifiers thiab proteins. Nws ruaj khov dhau sijhawm, pH thiab qhov kub thiab txias dav.
Kev siv uas pom zoo Vim nws cov dej solubility tshwj xeeb, DMDMH tuaj yeem ntxiv rau cov tshuaj pleev thiab cov tshuaj ntxuav tes uas muaj qhov concentration ntawm 0.2 ~ 0.6%. Yog tias DMDMH raug ntxiv rau cov surfactant, nws qhov kub feem ntau yog 50 ℃ ~ 60 ℃, thiab pH yog nyob rau hauv qhov ntau ntawm 7.5 ~ 8.5. Vim tias cov khoom xyaw thiab cov qauv ntawm cov khoom siv tu tus kheej sib txawv heev, uas yuav cuam tshuam rau qhov ua tau zoo ntawm cov tshuaj preservatives, peb xav kom koj paub meej tias qhov ua tau zoo thiab ruaj khov ntawm DMDMH ua ntej tsim khoom.
