Tala'aga o Gaosiga ma Su'esu'ega o Cellulose Ethers

O le cellulose ethers e iai se tala'aga umi o gaosiga ma su'esu'ega, na amata mai i le fa'ai'uga o le 19 seneturi. O le muamua cellulose ether, ethyl cellulose, na atiina ae i le 1860s e le kemisi Peretania Alexander Parkes. I le amataga o le 1900s, o le isi cellulose ether, methyl cellulose, na fausia e le fomaʻi Siamani Arthur Eichengrün.

I le 20th seneturi, o le gaosiga ma suʻesuʻega o cellulose ethers na faʻalauteleina tele. I le 1920s, na fausia ai le carboxymethyl cellulose (CMC) e avea o se ether cellulose e mafai ona solu vai. Na sosoo ai ma le atinaʻeina o le hydroxyethyl cellulose (HEC) i le 1930s, ma le hydroxypropyl methyl cellulose (HPMC) i le 1950s. O nei cellulose ethers o loʻo faʻaaogaina lautele i aso nei i le tele o alamanuia, e aofia ai meaʻai, vailaʻau, mea teuteu, ma faufale.

I totonu o pisinisi taumafa, e faʻaaogaina le cellulose ethers e fai ma mea mafiafia, emulsifiers, ma faʻamautu. E masani ona faʻaaogaina i oloa e pei o salati salati, aisakulimi, ma mea tao tao. I totonu o le falemaʻi vailaʻau, e faʻaaogaina le cellulose ethers e fai ma fusi, faʻamaʻi, ma mea faʻapipiʻi i totonu o laupepa ma capsules. I totonu o le alamanuia cosmetics, e faʻaaogaina e avea ma mea mafiafia ma emulsifiers i kulimi ma lotions. I totonu o fale faufale, e faʻaaogaina le cellulose ethers e fai ma vai faʻatumauina ma faʻaleleia galuega i le sima ma le sima.

O su'esu'ega ile cellulose ethers o lo'o fa'aauau pea e o'o mai i aso nei, ma le fa'amoemoe ile atina'eina o mea fou ma le fa'aleleia ole cellulose ethers fa'atasi ai ma le fa'aleleia o meatotino ma galuega. O le alualu i luma i tekinolosi ua taʻitaʻia ai le atinaʻeina o auala fou mo le gaosia o le cellulose ethers, e pei o le enzymatic modification ma le vailaʻau faʻaogaina e faʻaaoga ai mea lanu meamata. Ole su'esu'ega faifaipea ma le atina'eina ole cellulose ethers e fa'amoemoe e ta'ita'ia ai ni talosaga fou ma maketi mo nei mea fa'apitoa i tausaga a sau.
