O le fuafuaina o le "sili" cellulose ether e faʻalagolago i manaʻoga faʻapitoa o le faʻaogaina o le talosaga. Eseese cellulose ethers o loʻo faʻaalia uiga eseese, e pei o le viscosity, solubility, ma le faʻaogaina o ata tifaga, e faʻaogaina ai mo faamoemoega maʻoti. O nisi nei o ethers cellulose e masani ona faʻaaogaina ma faʻapitoa:

1. Methyl Cellulose (MC):
   • Meatotino: MC ua lauiloa mo lona maualuga maualuga o le taofiofia o le vai, e talafeagai ai mo le faʻaaogaina i le mafiafia o talosaga, aemaise lava ile fale faufale. E faʻaaogaina foi i vailaʻau ma meaʻai.
   • Fa'aaogāina: Fa'asusu ma fa'amea sima, vaila'au fa'ama'i, ma e fai ma sui fa'amalo i mea'ai.
2. Hydroxyethyl Cellulose (HEC):
   • Meatotino: O le HEC o loʻo ofoina atu le vai faʻafefeteina lelei ma e faʻaogaina i le tulaga o le pulea o le viscosity. E masani ona faʻaaogaina i fale gaosi oloa ma oloa faʻatau.
   • Fa'aoga: Vali ma fa'alavalava, mea e teu ai le tagata lava ia (shampoo, lotion), mea fa'apipi'i, ma fa'ama'i vaila'au.
3. Carboxymethyl Cellulose (CMC):
   • Meatotino: CMC e solu vai ma e sili ona mafiafia ma fa'amautu meatotino. E fa'aaogaina lautele i mea'ai ma falema'i.
   • Talosaga: Mea'ai mea'ai (e pei o se mafiafia ma fa'amautu), vaila'au, mea teuteu, 'ie, ma sua suau'u i totonu ole suau'u ma kesi.
4. Hydroxypropyl Methyl Cellulose (HPMC):
   • Meatotino: HPMC e ofoina atu se paleni lelei o le soluble vai, gelation vevela, ma meatotino fai ata. E faʻaaogaina lautele i le fausiaina ma le faʻaogaina o vailaʻau.
   • Talosaga: Fa'apipi'i ta'i, sima fa'avae, fa'atutuga fa'afoma'i tu'u gutu, ma faiga fa'amalo tu'uina atu vaila'au.
5. Ethyl Hydroxyethyl Cellulose (EHEC):
   • Meatotino: EHEC ua lauiloa ona o le maualuga o le viscosity ma le taofiofia o le vai, e talafeagai ai mo le manaʻomia o talosaga i le fausiaina ma vailaʻau.
   • Fa'aoga: Mea fa'aopoopo o le sima, mea mafiafia i vaila'au, ma mea teuteu.
6. Sodium Carboxymethyl Cellulose (Na-CMC):
   • Meatotino: Na-CMC o se vai-soluble cellulose ether ma sili ona mafiafia ma fa'amautu meatotino. E masani ona faʻaaogaina i meaʻai ma faʻaoga eseese tau pisinisi.
   • Talosaga: Mea'ai mea'ai (e pei o se mafiafia ma fa'amautu), vaila'au, 'ie, ma sua sua.
7. Microcrystalline Cellulose (MCC):
   • Meatotino: MCC o lo'o i ai ni mea laiti, tioata tioata ma e masani ona fa'aoga e fai ma mea fa'apipi'i ma fa'atumu i totonu o fualaau fa'ama'i.
   • Fa'aaogāga: Fualaau fa'ama'i ma capsules.
8. Sodium Carboxymethyl Starch (CMS):
   • Meatotino: O le CMS o se mea e maua mai i le masoa ma mea totino e tutusa ma le Na-CMC. E masani ona faʻaaogaina i fale gaosi meaʻai.
   • Fa'aoga: Mea'ai mea'ai (e pei o se mafiafia ma fa'amautu), 'ie, ma vaila'au.

Pe a filifilia se cellulose ether mo se faʻaoga faʻapitoa, e taua tele le mafaufau i mea e pei o le viscosity manaʻomia, solubility, mautu, ma isi uiga faʻatinoga. E le gata i lea, e tatau ona amanaia le tausisia o tulaga faatonuina ma iloiloga o le siosiomaga. E masani ona tuʻuina atu e le au gaosiga faʻamatalaga faʻamatalaga faʻapitoa faʻatasi ai ma faʻamatalaga auʻiliʻili i mea totino ma faʻatonuga faʻaoga o cellulose ethers.
