Amanzi abandayo akhawulezayo i-hydroxypropyl methylcellulose (HPMC) yi-ether ye-cellulose engeyiyo ionic esetyenziswa kakhulu kumashishini ahlukeneyo kuquka imboni yemichiza yemihla ngemihla. I-HPMC sisithako esithandwayo kukhathalelo lobuqu oluninzi kunye neemveliso zokucoca ikhaya ngenxa yogcino lwamanzi olugqwesileyo kunye nokutyeba. Kweli nqaku, siza kuxoxa ngeenzuzo zokusebenzisa amanzi abandayo HPMC ngoko nangoko kushishino imichiza mihla.
Phucula uzinzo
Enye yeenzuzo eziphambili zokusebenzisa i-HPMC yamanzi abandayo ngoko nangoko kukhathalelo lomntu kunye neemveliso zokucoca izindlu kukuphucula uzinzo. I-HPMC yinto ene-hydrophilic ekwazi ukufunxa kwaye igcine izixa ezikhulu zamanzi. Ngaloo ndlela, kunceda ukugcina ukuzinza kwemveliso ngokuthintela imveliso ukuba yome okanye ilahlekelwe ukuthungwa kwexesha.
Ukongeza, i-HPMC ineempawu ezibalaseleyo zokwenza ifilimu, ezinceda ukwenza umaleko ofanayo kunye nohambelanayo kumphezulu wemveliso. Oku kukhusela imveliso kwizinto zangaphandle ezifana nomswakama, iikhemikhali kunye nokutshintsha kweqondo lokushisa, ngaloo ndlela kuphuculwe ukuzinza kwemveliso.
Ukuphucula i-viscosity
Olunye uncedo lokusebenzisa amanzi abandayo e-HPMC ngoko nangoko kukhathalelo lomntu kunye neemveliso zokucoca izindlu kukwanda kwe-viscosity. I-HPMC ineempawu ezityebisayo ezinokuphucula ukuthungwa kunye ne-viscosity yeemveliso. Oku kuluncedo ngakumbi kwiimveliso ezifuna ukungaguquguquki okuthile, okufana neshampu, imizimba yokuhlamba umzimba kunye neesepha ezingamanzi.
Ukongeza, i-HPMC ifumaneka kwiindidi ezahlukeneyo ze-viscosity, oku kuthetha ukuba abavelisi banokukhetha ibakala elilungele imveliso yabo ethile. Oku kuvumela ukuguquguquka okukhulu ekuqulunqweni kwemveliso, okubalulekileyo kushishino lwezithambiso olukhuphisana kakhulu.
Ukuphucula ukugcinwa kwamanzi
Amanzi abandayo ngoko nangoko i-HPMC ifaneleke ngokukodwa kwiimveliso ezifuna ukugcinwa kwamanzi aphezulu. I-HPMC inokufunxa kwaye igcine isixa esikhulu samanzi, inceda ukuthambisa ulusu kunye neenwele. Oku kubaluleke ngakumbi kwiimveliso zokhathalelo lomntu ezifana nezinto zokuthambisa, izinto zokuthambisa kunye nezipholileyo.
Ukongeza, i-HPMC inokunceda ukuthintela ukuvela kwamanzi kwiimveliso. Oku kubaluleke kakhulu kwiimveliso ezivezwe kumswakama ophezulu, ezifana nokuhlamba umzimba kunye neesepha ezimanzi. Ngokuthintela ukufuma ekuphumeni, i-HPMC inceda ukugcina ukuthungwa kunye nokuhambelana kwemveliso, ngaloo ndlela iphucula umgangatho wayo jikelele.
Ukuphucula iipropati zokumisela
Okokugqibela, amanzi abandayo ngoko nangoko HPMC ineepropati emulsifying ebalaseleyo, nto leyo ethetha ukuba inceda izithako ukubopha nokuzinzisa kwimveliso. Oku kubaluleke kakhulu kwiimveliso ezinezithako ezisekelwe kwioli kunye nezamanzi, ezifana ne-lotions kunye ne-creams.
I-HPMC inceda ukwenza i-emulsions ezinzileyo ngokwenza umqobo phakathi kwezigaba ze-oyile kunye namanzi. Lo mqobo uthintela izithako ukuba zihlukane kwaye unceda ukugcina ukuhambelana kwemveliso. Oku kuphucula umgangatho wemveliso ngokuqinisekisa ukuba inokwakheka okuhambelanayo kwaye kulula ukuyisebenzisa.
ukuququmbela
Ukuqukumbela, amanzi abandayo akhawulezayo i-hydroxypropyl methylcellulose (HPMC) sisithako esisebenzayo nesiluncedo kwishishini lemichiza yemihla ngemihla. Ukugcinwa kwayo kwamanzi, ukuqina, ukuzinzisa, kunye neempawu ze-emulsifying zenza ukuba ibe yinto exabisekileyo kwiintlobo zokhathalelo lomntu kunye neemveliso zokucoca indlu. Izibonelelo zokusebenzisa i-HPMC kwezi mveliso ziquka ukuzinza okuphuculweyo, i-viscosity, ukugcinwa kwamanzi kunye neempawu ze-emulsification. Ukusetyenziswa kwayo ngokubanzi kwishishini lithetha ngokusebenza kwe-HPMC kunye nempembelelo yayo yonke elungileyo kumgangatho weemveliso zemichiza yemihla ngemihla.
