I-Hydroxypropylmethylcellulose
Eyaziwa kakhulu ngesifinyezo sayo esithi HPMC, iyipolymer eguquguqukayo esetshenziswa kabanzi ezimbonini ezahlukahlukene. Le polymer encibilika emanzini isuselwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. I-HPMC ihlanganiswa ngokwelapha i-cellulose nge-propylene oxide ne-methyl chloride, idale inhlanganisela enezici ezihlukile ezingathola ukusetshenziswa kwemithi, ukudla, ukwakhiwa, izimonyo neminye imikhakha.
embonini yezemithi
I-HPMC isetshenziswa kakhulu njengesithako esisizayo noma esingasebenzi ekwakhiweni kwemithi. Inemisebenzi eminingi, njengokulawula ukukhishwa kwezithako zemithi esebenzayo, ukuthuthukisa ukuzinza kwezidakamizwa, nokuthuthukisa ikhwalithi iyonke yemithi. Ngenxa ye-biocompatibility yayo kanye nokungabi nobuthi, i-HPMC ithathwa njengento ephephile nengasebenziyo ekwakhiweni kwemithi yomlomo neyesihloko.
embonini yokudla
I-HPMC isebenza njenge-thickener, stabilizer kanye ne-emulsifier. Ivame ukusetshenziswa ekukhiqizeni imikhiqizo yokudla njengamasoso, okokugqoka kanye nezimpahla ezibhakwayo. Ikhono le-HPMC lokwenza amajeli namafilimu acacile liyenza ifaneleke izinhlelo zokusebenza lapho ukuthungwa nokubukeka kubaluleke kakhulu. Ukwengeza, izakhiwo zayo ezigcina amanzi zisiza ukunweba impilo yeshalofu yokudla okuthile.
embonini yezokwakha
I-HPMC isetshenziswa ezinhlobonhlobo zezinto zokwakha. Ivamise ukungezwa emikhiqizweni esekwe usimende, okuhlanganisa udaka, amapulastele nezinamathiselo zamathayela, ukuze kuthuthukiswe ukusebenza kahle, ukugcinwa kwamanzi nokunamathela. I-HPMC ingasetshenziswa futhi njengesilungisi se-rheology ukuze kuthuthukiswe ukungaguquguquki nokusebenza kwezinto zokwakha.
Embonini yezimonyo nokunakekelwa komuntu siqu
I-HPMC isetshenziswa emikhiqizweni efana namakhilimu, izinto zokuthambisa kanye nama-shampoos. Izakhiwo zayo zokwenza ifilimu zisiza ekudaleni ubushelelezi, ngisho nokuthungwa kwefomula yezimonyo, kuyilapho amandla ayo okubamba amanzi enomthelela emthelela wokuswakama wemikhiqizo yokunakekelwa kwesikhumba.
Izakhiwo zomzimba nezamakhemikhali ze-HPMC zingalungiswa ngokulungisa izici ezifana nezinga lokushintshwa kanye nesisindo samangqamuzana phakathi nenqubo yokukhiqiza. Lokhu kuvumelana nezimo kuvumela i-HPMC ukuthi yenziwe ngendlela oyifisayo ukuze ihlangabezane nezimfuneko ezithile zezinhlelo zokusebenza ezihlukahlukene.
IHydroxypropyl methylcellulose (HPMC) iyi-polymer esebenzayo esetshenziswa kabanzi ezimbonini ezahlukahlukene. Ukuguquguquka kwayo, ukuphepha, kanye nekhono lokushintsha izici zemikhiqizo ehlukahlukene kuyenza ibe isithako esibalulekile kwezemithi, ukudla, ukwakhiwa, izimonyo, nokunye.
