Nws kuj hu ua dimethylaminoethanol. Cov kev tshawb fawb qhia txog cov khoom ua rau tawv nqaij khov kho, thiab muaj peev xwm txo cov kab zoo thiab cov pob khaus nrog rau cov voj voog tsaus nti hauv qab lub qhov muag. Nws suav hais tias yog tiv thaiv kev laus, thiab tiv thaiv kev o, thiab tau ua haujlwm tshem tawm cov dawb-radical. Kuj siv ua tus neeg tiv thaiv kev xeb, tus neeg sawv cev tiv thaiv kev ua kom tawv nqaij, cov tshuaj pleev xim, cov tshuaj pleev xim thiab cov neeg sawv cev sib cais. Nws kuj siv ua tus neeg nruab nrab rau cov khoom xyaw tshuaj thiab cov xim pleev xim. Nws ua haujlwm ua tus neeg sawv cev kho rau polyurethanes thiab epoxy resins. Ntxiv mus, nws siv ua tus neeg ntxiv rau dej boiler. Ntxiv rau qhov no, nws siv kho mob ua tus neeg txhawb nqa CNS.
