I-HEC (iHydroxyethyl Cellulose)yipolymer eqhelekileyo enyibilikayo emanzini esetyenziswa kakhulu kumalungiselelo eyeza. Yinto evela kwi-cellulose, efunyanwa ngokuphendula i-ethanolamine (i-ethylene oxide) kunye ne-cellulose. Ngenxa yokunyibilika kwayo okuhle, ukuzinza, amandla okulungisa i-viscosity kunye nokuhambelana kwayo nezinto eziphilayo, i-HEC ineendlela ezininzi zokusetyenziswa kwicandelo leyeza, ngakumbi kuphuhliso lwefomyula, uyilo lwefom yedosi kunye nolawulo lokukhululwa kwamayeza.
1. Iimpawu ezisisiseko ze-HEC
I-HEC, njenge-cellulose eguquliweyo, ineempawu ezilandelayo ezisisiseko:
Ukunyibilika kwamanzi: I-AnxinCel®HEC inokwenza isisombululo esiqinileyo emanzini, kwaye ukunyibilika kwayo kunxulumene nobushushu kunye ne-pH. Le mpawu yenza ukuba isetyenziswe kwiindlela ezahlukeneyo zomthamo ezifana nokusela kunye nokusela.
Ukuhambelana kwezinto eziphilayo: I-HEC ayinabungozi kwaye ayicaphukisi emzimbeni womntu kwaye iyahambelana namayeza amaninzi. Ke ngoko, isetyenziswa kakhulu kwiifom zedosi ezikhutshwa rhoqo kunye neendlela zolawulo lwasekhaya lwamayeza.
Ukuqina okulungisekayo: Ukuqina kwe-HEC kunokulungiswa ngokutshintsha ubunzima bayo beemolekyuli okanye uxinaniso, nto leyo ibalulekileyo ekulawuleni izinga lokukhululwa kwamayeza okanye ukuphucula uzinzo lwamayeza.
2. Ukusetyenziswa kwe-HEC kumayeza
Njengesixhobo esibalulekileyo sokuncedisa ekulungiseleleni amayeza, i-HEC inemisebenzi emininzi. Nazi iindawo eziphambili zokusetyenziswa kwayo ekulungiseleleni amayeza.
2.1 Ukusetyenziswa ekulungiseleleni ngomlomo
Kwiindlela zokuthatha idosi ngomlomo, i-HEC idla ngokusetyenziswa ekwenzeni iipilisi, iikhaphu kunye namalungiselelo olulwelo. Imisebenzi yayo ephambili ibandakanya:
I-Binder: Kwiipilisi nakwiigranules, i-HEC ingasetyenziswa njenge-binder yokubopha ngcono amasuntswana eziyobisi okanye iipowders kunye ukuqinisekisa ubulukhuni kunye nokuzinza kweepilisi.
Ulawulo lokukhululwa oluqhubekayo: I-HEC inokufezekisa isiphumo sokukhululwa esiqhubekayo ngokulawula izinga lokukhululwa kwesiyobisi. Xa i-HEC isetyenziswa kunye nezinye izithako (ezifana ne-polyvinyl pyrrolidone, i-carboxymethyl cellulose, njl.njl.), inokwandisa ngokufanelekileyo ixesha lokukhululwa kwesiyobisi emzimbeni, inciphise ukuphindaphinda kwamayeza, kwaye iphucule ukuthobela kwezigulane.
Isiqinisi: Kwizinto eziselwayo ngolwelo, i-AnxinCel®HEC njengesiqinisi inokuphucula incasa yeyeza kunye nokuzinza kwefom yomthamo.
2.2 Ukusetyenziswa kwilungiselelo le-topical
I-HEC isetyenziswa kakhulu kwizithambiso zasekhaya, iikhrimu, iijeli, iiloshini kunye nezinye izinto ezilungiselelweyo, idlala indima ezininzi:
I-gel matrix: I-HEC idla ngokusetyenziswa njenge-matrix yee-gel, ingakumbi kwiinkqubo zokuhambisa amayeza e-transdermal. Ingabonelela ngokuhambelana okufanelekileyo kwaye yonyuse ixesha lokuhlala kwesiyobisi eluswini, ngaloo ndlela iphucula ukusebenza kakuhle.
Ukuqina kunye nokuzinza: Ukuqina kwe-HEC kunokunyusa ukunamathela kwezinto ezilungiselelweyo eluswini kwaye kuthintele ukuba ichiza lingawi ngaphambi kwexesha ngenxa yezinto zangaphandle ezifana nokungqubana okanye ukuhlamba. Ukongeza, i-HEC inokuphucula ukuzinza kweekhrimu kunye namafutha kwaye ithintele ukuqhekeka okanye ukwakheka kwekristale.
Isithambisi kunye nesithambisi solusu: I-HEC ineempawu ezilungileyo zokufumisa kwaye inokunceda ukugcina ulusu lumanzi kwaye luthintele ukoma, ngoko ke ikwasetyenziswa kwizithambisi kunye nezinye iimveliso zokhathalelo lolusu.
2.3 Ukusetyenziswa kulungiselelo lwamehlo
Ukusetyenziswa kwe-HEC kumalungiselelo amehlo kubonakala kakhulu kwindima yayo njenge-adhesive kunye ne-lubricant:
Iijeli zamehlo kunye namaconsi amehlo: I-HEC ingasetyenziswa njengesincamathelisi sokulungiselela amehlo ukwandisa ixesha lokudibana phakathi kweyeza neliso nokuqinisekisa ukusebenza kakuhle kwesiyobisi. Kwangaxeshanye, ukuxinana kwayo kunokuthintela ukuhla kwamehlo ekulahlekelweni ngokukhawuleza kwaye kwandise ixesha lokugcina ichiza.
Ukuthambisa: I-HEC inomswakama olungileyo kwaye inokubonelela ngokuthambisa okuqhubekayo kunyango lwezifo zamehlo ezifana neliso elomileyo, nto leyo enciphisa ukungonwabi kwamehlo.
2.4 Ukusetyenziswa kumalungiselelo enaliti
I-HEC ingasetyenziswa nasekulungiseleleni iifom zedosi yenaliti, ingakumbi kwiinaliti ezisebenza ixesha elide kunye namalungiselelo okukhululwa ixesha elide. Imisebenzi ephambili ye-HEC kula malungiselelo ibandakanya:
Isiqinisi kunye nesiqinisi: Esifakwa kwinaliti,I-HECinokunyusa ukuxinana kwesisombululo, inciphise isantya sokufakwa kwesiyobisi, kwaye iphucule uzinzo lwesiyobisi.
Ukulawula ukukhululwa kwamayeza: Njengenye yezinto eziyinxalenye yenkqubo yokukhululwa kwamayeza rhoqo, i-HEC inokulawula izinga lokukhululwa kwamayeza ngokwenza umaleko wejeli emva kokufakwa, ukuze kufezekiswe injongo yonyango lwexesha elide.
3. Indima ye-HEC kwiinkqubo zokuhambisa iziyobisi
Ngophuhliso lwetekhnoloji yamayeza, i-HEC isetyenziswa kakhulu kwiinkqubo ezahlukeneyo zokuhambisa amayeza, ingakumbi kwicandelo labathwali beziyobisi ezincinci, ii-microspheres, kunye nabathwali beziyobisi abakhululwa rhoqo. I-HEC inokudityaniswa nezixhobo ezahlukeneyo zokuthwala amayeza ukuze yenze i-complex ezinzileyo ukuqinisekisa ukukhutshwa okuqhubekayo kunye nokuhanjiswa ngokufanelekileyo kwamayeza.
Umthwali weziyobisi zeNano: I-HEC ingasetyenziswa njengesiqinisi seenkampani ezithwala iziyobisi zeNano ukuthintela ukuhlangana okanye ukuna kweesuntswana zezixhobo ezithwala kunye nokunyusa ukufumaneka kwamayeza.
IiMicrospheres kunye namasuntswana: I-HEC ingasetyenziselwa ukulungiselela iimicrospheres kunye nabathwali beziyobisi be-microparticle ukuqinisekisa ukukhululwa kancinci kwamayeza emzimbeni kunye nokuphucula ukusebenza kakuhle kwamayeza.
Njengesixhobo sokuxuba amayeza esisebenza ngeendlela ezininzi nesisebenzayo, i-AnxinCel®HEC inamathuba amaninzi okusetyenziswa kulungiselelo lwamayeza. Ngophuhliso oluqhubekayo lwetekhnoloji yamayeza, i-HEC idlala indima ebaluleke ngakumbi kulawulo lokukhululwa kwamayeza, ulawulo lwasekhaya, amalungiselelo okukhululwa okuqhubekayo kunye neenkqubo ezintsha zokuhanjiswa kwamayeza. Ukuhambelana kwayo okuhle kwezinto eziphilayo, i-viscosity ehlengahlengiswayo kunye nozinzo kwenza ukuba ingathathelwa indawo kwicandelo lezonyango. Kwixesha elizayo, ngophando olunzulu lwe-HEC, ukusetyenziswa kwayo kulungiselelo lwamayeza kuya kuba kubanzi kwaye kuhluke ngakumbi.
