Cellulose ethers o se vaega 'ese'ese o mea e maua mai i vaila'au fa'asolosolo fa'anatura cellulose, o le vaega autu o pa puipui o laau. Ole ituaiga fa'apitoa ole cellulose ether e fa'amoemoeina ile natura ole suiga ole vaila'au na fa'aofiina ile ivi tua ole cellulose. O nisi nei o ituaiga masani o cellulose ethers, e taʻitasi ma ona uiga faʻapitoa ma faʻaoga:

1. Methyl Cellulose (MC):
   • Suiga Vailaau: Fa'aofia vaega methyl i luga ole ponaivi sela.
   • Meatotino ma Talosaga:
     • Solu vai.
     • Fa'aaogaina i mea faufale (mea faufale, mea fa'apipi'i), mea'ai, ma vaila'au (fa'aofuofu papa'a).
2. Hydroxyethyl Cellulose (HEC):
   • Su'iga vaila'au: Fa'aofiina o vaega o le hydroxyethyl i luga ole ponaivi o le cellulose.
   • Meatotino ma Talosaga:
     • E sili ona solu i le vai.
     • E masani ona fa'aoga i mea teuteu, mea tau le tagata lava ia, vali, ma vaila'au.
3. Hydroxypropyl Methyl Cellulose (HPMC):
   • Su'iga vaila'au: Fa'aofiina o vaega hydroxypropyl ma methyl i luga ole ponaivi cellulose.
   • Meatotino ma Talosaga:
     • Solu vai.
     • Fa'aaoga lautele i mea faufale (motars, coatings), pharmaceuticals, ma mea taumafa.
4. Carboxymethyl Cellulose (CMC):
   • Suiga Vailaau: Fa'aofia vaega carboxymethyl i luga ole ponaivi sela.
   • Meatotino ma Talosaga:
     • Solu vai.
     • Fa'aaogaina e fai ma mea mafiafia ma fa'amautu i mea'ai, vaila'au, ie, ma sua sua.
5. Hydroxypropyl Cellulose (HPC):
   • Su'iga vaila'au: Fa'aofiina o vaega hydroxypropyl i luga ole ponaivi o le cellulose.
   • Meatotino ma Talosaga:
     • Solu vai.
     • E masani ona faʻaaogaina i vailaʻau faʻapitoa e pei o se mea e fusifusia ai, sui faʻapipiʻi ata, ma le mafiafia.
6. Ethyl Cellulose (EC):
   • Suiga Vailaau: Fa'aofiina o vaega ethyl i luga o le ivi ivi sela.
   • Meatotino ma Talosaga:
     • E le mafai ona fa'afefeteina le vai.
     • Fa'aaogaina i fa'alavalava, ata tifaga, ma fa'atonu-fa'asa'oloto fa'ama'i vaila'au.
7. Hydroxyethyl Methyl Cellulose (HEMC):
   • Suiga Vailaau: Fa'aofiina o vaega o le hydroxyethyl ma le methyl i luga ole ponaivi o le cellulose.
   • Meatotino ma Talosaga:
     • Solu vai.
     • E masani ona fa'aoga i mea faufale (motars, grouts), vali, ma mea teuteu.

O nei ituaiga o cellulose ethers e filifilia e faʻatatau i a latou mea totino ma galuega e manaʻomia mo faʻaoga eseese. Ole suiga ole vaila'au e fuafua ai le solubility, viscosity, ma isi uiga fa'atinoga o le cellulose ether ta'itasi, ma avea ai i latou ma mea fa'aopoopo i fale gaosi oloa e pei o le fausiaina, vaila'au, mea'ai, mea teuteu, ma isi mea.
