I le lalolagi o loʻo vave ona suia o vailaʻau ma oloa faʻamamā i aso taʻitasi, ua sili atu le maualuga o faʻamoemoega o le faʻatinoga nai lo se isi lava taimi. E manaʻomia e tagata faʻatau ni oloa e le gata ina aoga ae mautu foʻi, faigofie ona faʻaaoga, e le afaina ai le siosiomaga, ma manaia le foliga ma le lagona. I tua atu o nei uiga faʻatino o loʻo i ai se vasega taua o mea aoga—ethers cellulose.
Faatasi ai ma i latou,Carboxymethyl Cellulose (CMC)), Hydroxyethyl Cellulose (HEC)), maHydroxypropyl Methyl Cellulose (HPMC)e fa'aaogaina lautele i vaila'au fufulu, fasimoli vai, shampoos, mea fa'amama, ma isi mea fa'apitoa mo le tausiga o le fale po'o le tagata lava ia. Peita'i, o nei mea e tolu e masani ona fa'aalia aiamioga fa'atino eseese tele, e ta'ita'ia ai le au fa'atulaga mea e filifili ma le fa'aeteete le filifiliga e sili ona talafeagai.
O taʻitaʻi o le lalolagi e pei o Ashland Global Holdings Inc., Dow Chemical Company, ma Shin-Etsu Chemical Co., Ltd. o loʻo faʻaauau pea ona atiaʻe ni fofo faʻapitoa mo le cellulose ether ua faʻapitoa mo nei faʻaoga.
O lenei tusiga o loʻo tuʻuina atu ai se auiliiliga atoatoa, faʻa-tala fou oaisea e eseese ai le faatinoga a le CMC, HEC, ma le HPMC—ma po o fea e tatau ona filifilia mo ni talosaga faapitoa.
1. Eseesega Fa'avae i le Fa'atulagaga Fa'akemikolo
O le pogai autū o eseesega o le faatinoga o loo taoto i la latoufausaga fa'akemikolo ma vaega suia.
CMC (Carboxymethyl Cellulose)
- O lo'o iai vaega o le carboxymethyl (-CH₂COOH)
- Polimer anionic(ua molia i le leaga)
- Maualuga le solubility i le vai ma le fegalegaleaiga malosi ma ions
HEC (Hydroxyethyl Cellulose)
- O lo'o iai vaega hydroxyethyl (-CH₂CH₂OH)
- Polimer e lē o le ionic
- Mausali lelei i vaega eseese o le pH
HPMC (Hydroxypropyl Methyl Cellulose)
- O lo'o iai vaega methyl ma hydroxypropyl
- Polimer e lē o le ionicma le hydrophobicity fa'aitiiti
- Faaalia le amioga o le fa'avevela o le vevela
