IHydroxypropyl methylcellulose kanye ne-sodium carboxymethylcellulose yizinto ezimbili eziphuma ku-cellulose ezisetshenziswa kabanzi ezimbonini ezahlukahlukene. Zonke zinezakhiwo ezihlukile futhi zivame ukungezwa ekudleni, emithini yemithi, kwezimonyo nasezintweni zokwakha. Umbuzo ovame ukubuzwa ochwepheshe bemboni ukuthi i-hydroxypropyl methylcellulose ne-sodium carboxymethylcellulose ingaxutshwa yini. Impendulo inguyebo, zingaxutshwa futhi izinzuzo zale nhlanganisela ziningi.
IHydroxypropylmethylcellulose, eyaziwa nangokuthi i-HPMC, i-cellulose eshintshiwe eshintshwe amakhemikhali ukuze kuthuthukiswe izakhiwo zayo. Isetshenziswa kakhulu njenge-thickener ne-emulsifier ekudleni, kwizimonyo nakwezemithi. I-HPMC incibilika kalula emanzini, ihlinzeka ngesixazululo esizinzile, esicacile. Yaziwa futhi nge-viscosity yayo ephezulu kanye nezakhiwo ezinhle kakhulu zokwakha amafilimu.
Ngakolunye uhlangothi, i-sodium carboxymethylcellulose, eyaziwa nangokuthi i-CMC, iphuma ku-cellulose encibilika emanzini esetshenziswa kabanzi njenge-thickener ne-stabilizer ekudleni nakwezemithi. I-cellulose etholakala ngokusabela kwe-sodium chloroacetate ne-cellulose. I-CMC futhi ayinabo ubuthi, ayinabo ubuthi futhi ayihambisani nemvelo.
I-HPMC ne-CMC zinezakhiwo ezihambisanayo ezizenza inhlanganisela ekahle yezinhlelo zokusebenza ezihlukahlukene. Zombili zincibilika kakhulu emanzini futhi zinezakhiwo ezinhle kakhulu zokujiya kanye ne-emulsifying. Ukwengeza, zonke ziyahambisana nohlu olubanzi lwamakhemikhali nezinye izithako, ezivumela ukuthi zisetshenziswe emikhiqizweni ehlukahlukene.
Lapho i-HPMC ne-CMC kuxutshwe, ikhambi eliwumphumela linezinzuzo ezimbalwa. Enye yezinzuzo eziyinhloko ukuthi inikeza isilawuli se-viscosity esihle kakhulu, okusho ukuthi singasetshenziswa njenge-thickener emikhiqizweni ehlukahlukene, kufaka phakathi ama-lotions, ama-shampoos neminye imikhiqizo yokunakekelwa komuntu siqu. Ukwengeza, inhlanganisela ye-HPMC ne-CMC inikeza ukuzinza okuhle, okuyenza ibe ukukhetha okuhle kakhulu emikhiqizweni edinga ukushuba nokusimama kwesikhathi eside.
Enye inzuzo yokuxuba i-HPMC ne-CMC ukuthi ingathuthukisa ukuhlakazwa kwezithako. Uma kokubili kusetshenziswe ndawonye, kungasiza ukusabalalisa izithako ngokulinganayo kuwo wonke umkhiqizo, ukuthuthukisa ukusebenza kwawo jikelele. Lokhu kuwusizo ikakhulukazi kwezokwelapha lapho ukusabalalisa okufanayo kwesithako esisebenzayo kubalulekile.
Kokubili i-HPMC kanye ne-CMC nazo zisetshenziswa embonini yezokwakha. Uma zisetshenziswa ndawonye, zinikeza ukunamathela okuhle kakhulu kanye ne-viscosity, okubalulekile ezinhlelweni eziningi zokwakha. Inhlanganisela futhi izinzile kakhulu, okusho ukuthi ingasetshenziswa emikhiqizweni eminingi ngaphandle kokukhathazeka ngokuhlukana.
IHydroxypropyl methylcellulose kanye ne-sodium carboxymethylcellulose yizinto ezimbili eziphuma ku-cellulose ezingaxutshwa futhi zisetshenziswe ndawonye ezinhlobonhlobo zezinhlelo zokusebenza. Izixazululo eziwumphumela zinikeza inhlanganisela enhle kakhulu yezakhiwo ezihlanganisa ukulawulwa kwe-viscosity, ukuzinza kanye nokuhlakazeka kwesithako okuthuthukisiwe. Kungakhathaliseki ukuthi kusekudla, kwezemithi, kwezimonyo noma ezintweni zokwakha, inhlanganisela ye-HPMC ne-CMC iqinisekile ukunikeza imiphumela emihle kakhulu.
