Polyethylene Oxide (PEO)

O le polyethylene oxide (PEO), e lauiloa foi o le polyethylene glycol (PEG) poʻo le polyoxyethylene, o se polymer faʻapitoa ma le tele o faʻaoga i totonu o pisinisi eseese.O se polymer e mafai ona solu vai e fausia i le toe faia o iunite ethylene oxide (-CH2-CH2-O-) ma e iloga i lona mamafa mole mole maualuga ma le natura hydrophilic.O loʻo faʻaalia e le PEO le tele o mea faʻapitoa e talafeagai mo le tele o faʻaoga, e aofia ai lona soluble i le vai, biocompatibility, ma le mafai ona fai ni fofo viscous. O nisi nei o vaega taua ole Polyethylene Oxide (PEO) ma ona faʻaoga: 1.Suavai-Solubility: O se tasi o mea sili ona taua o le PEO o lona solubility sili ona lelei i le vai.O lenei uiga e mafai ai ona faigofie le taulimaina ma le tuʻufaʻatasia i vaifofo vai, ma faʻatauaina i pisinisi eseese e pei o vailaʻau, tausiga a le tagata lava ia, ma meaʻai. 2.Thickening Agent: PEO o loʻo faʻaaogaina lautele e avea o se mea faʻafefeteina poʻo se suiga viscosity i le tele o talosaga.Pe a faʻamavae i totonu o le vai, o le PEO molecules e faʻapipiʻiina ma fausia ai se fausaga fesoʻotaʻiga, faʻateleina le viscosity o le fofo.O lenei meatotino e talafeagai mo le faʻaaogaina i oloa e pei o lotions, shampoos, ma vai vai. 3.Surface-Active Properties: E mafai e le PEO ona galue e avea o se mea e faʻaaogaina i luga ole laiga, faʻaitiitia le faʻalavelave i luga ole laiga ma faʻaleleia atili le susu ma le salalau o meatotino o vaifofo vai.O lenei meatotino e faʻaaogaina i talosaga e pei o vailaʻau, emulsifiers, ma faʻamalulu ie. 4.Pharmaceutical Applications: I totonu o falema'i falema'i, o lo'o fa'afaigaluegaina le PEO i le tele o faiga e tu'uina atu ai vaila'au, e aofia ai ma'a fa'atonu-fa'asa'oloto, vaifofo tu'ugutu, ma fa'atonuga autu.O lona biocompatibility, vai solubility, ma le gafatia e fai ai gels e avea ai ma mea e sili ona lelei mo vailaʻau. 5. Binder and Film Former: PEO e mafai ona avea o se fusifusia ma ata tifaga muamua i vailaʻau vailaʻau, lea e fesoasoani e faʻapipiʻi faʻatasi ai mea aoga ma tuʻuina atu se lanu lamolemole, toniga i luga o le laulau.E fa'aaogaina fo'i i le gaosiga o ata tifaga ma fa'alavalava mo mea'ai. 6. Suavai Togafitiga: O loʻo faʻaaogaina le PEO i le faʻaogaina o le vai e avea o se fugalaʻau ma fesoasoani faʻamalosi mo le faʻamalamalamaina ma le faʻamamaina o le vai.E fesoasoani e fa'aputu ma fa'ato'a fa'agata vaega, fa'aleleia atili le lelei o faiga fa'amama ma fa'apalapala. 7. Oloa Tausiga a le Tagata Lava Ia: PEO o se mea masani i mea tau tausiga a le tagata lava ia e pei o le toothpaste, mouthwash, ma le tausiga o lauulu.E galue e pei o se mafiafia, faʻamautu, ma mea e faʻamautu ai le susu, faʻaleleia le tino, mautu, ma le faʻatinoga o nei oloa. 8. Talosaga Fa'ale-aganu'u: E maua e le PEO ni fa'aoga fa'apisinisi eseese, e aofia ai i totonu fa'apipi'i, pa'u, lubricants, ma ie.O ona lubricating meatotino e talafeagai mo le faʻaaogaina e fai ma sui faʻasaʻo, aʻo ona faʻaogaina ata tifaga e faʻaaogaina i paʻu ma faʻapipiʻi. 9.Hydrogel Formation: PEO e mafai ona fausia hydrogels pe a fesoʻotaʻi faʻatasi ma isi polymers poʻo vailaʻau vailaʻau.O nei hydrogels o loʻo i ai faʻaoga i le faʻaofuina o manuʻa, faiga e tuʻuina atu ai vailaʻau, ma masini faʻainisinia, lea latou te maua ai le susu ma se matrix lagolago mo le tuputupu aʻe o sela. O le Polyethylene Oxide (PEO) o se polymer e tele ma le tele o faʻaoga i le tele o alamanuia.O lona solubility o le vai, mea mafiafia, biocompatibility, ma uiga galue i luga o le eleele e taua ai i vailaʻau, tausiga a le tagata lava ia, togafitiga vai, ma faʻaoga fale gaosi oloa.A'o fa'aauau su'esu'ega ma atina'e i polymer science, e fa'amoemoe le PEO e su'e ni fa'aoga fou ma fa'afou i vaega eseese.
