Carboxymethyl Cellulose (CMC): Fa'aoga, Fa'amanuiaga & Fa'aoga
1. Folasaga
Carboxymethyl Cellulose(CMC) o se polymer solu vai e maua mai i le cellulose, o se polysaccharide fa'alenatura o lo'o maua i puipui sela o la'au. CMC o loʻo faʻapipiʻiina e ala i le faʻaofiina o vaega carboxymethyl (-CH2-COOH) i totonu o le fausaga o le cellulose, faʻaleleia lona solubility ma galuega. Ona o ona uiga fa'apitoa e pei o le mafiafia, fa'amulumuluina, fa'amautu, ma le fa'atinoina o ata, o le CMC e fa'aaogaina lautele i le tele o alamanuia.
