Tshuaj Qib Polyethylene Oxide (PEO)

Txheej Txheem Cej Luam Khoom

Polyethylene Oxide (PEO) yog ib homopolymer nonionic ntawm ethylene oxide, uas sawv cev los ntawm cov mis H(OCH2CH2)nOH, qhov twg n sawv cev rau tus lej nruab nrab ntawm cov pab pawg oxyethylene uas nyob ntawm kwv yees li 2,000 txog 200,000.Nws yog ib qho khoom siv molecular siab, cov dej-soluble polymer dav siv ua ib qho tshuaj excipient hauv kev tswj hwm kev tso tawm formulations, granulation binders, zaj duab xis coatings, thiab mucoadhesive tshuaj xa systems..
