IHydroxypropylmethylcellulose (HPMC) I-E15 yinto esetyenziswa kwizinto ezininzi kwaye isetyenziswa ngeendlela ezininzi ekuxubeni amayeza, kwi-cosmetic kunye nokutya.Ithathwe kwi-cellulose yendalo, le nto iphuma kwi-cellulose ithandwa ngenxa yeempawu zayo ezizodwa, kubandakanywa ukukwazi ukuguqula i-viscosity yesisombululo, ukuphucula iiprofayili zokukhutshwa kweziyobisi, kunye nokuphucula ukuzinza kokwakheka.
1.HPMC E15 intshayelelo:
IHydroxypropyl methylcellulose (HPMC):
I-HPMC yi-semi-synthetic polymer ephuma kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo.Iveliswa ngokuphatha i-cellulose nge-alkali kwaye emva koko i-propylene oxide, okukhokelela kwiikhompawundi kunye ne-hydroxypropyl kunye ne-methoxy substituents.Olu hlengahlengiso lunika iipropati ezizodwa ze-HPMC, ziyenza ilungele usetyenziso oluhlukeneyo.
2. IHydroxypropyl methylcellulose E15:
I-HPMC E15 ibhekisa ngokukodwa kwibakala eliphakathi ukuya kwi-viscosity ephezulu ye-HPMC.I-"E" ekutyunjweni kwayo ibonisa ukuba ihambelana neenkcukacha ezichazwe kwi-European Pharmacopoeia.Eli bakala likhethekileyo lihlala lisetyenziswa ekuxutyweni kwamayeza ukufikelela kwiimpawu ezithile zokusebenza.
3.Usetyenziso lwamayeza:
A. Izibophelelo kuqulunqo lwethebhulethi:
I-HPMC E15 idla ngokusetyenziswa njengesibophelelo kwimixube yethebhulethi.Iimpawu zayo ezibophezelayo zinceda ukubopha isithako seyeza esisebenzayo (API) kunye nabancedisi kunye, ukuqinisekisa ithebhulethi edibeneyo kunye neyomelele.
B. Ii-agent ezenza i-Matrix kumalungiselelo okukhululwa alawulwayo:
I-HPMC E15 yenza i-matrix efana nejeli xa idibana namanzi, iyenza ilungele ukulawulwa okanye ukukhululwa okuqhubekayo.Oku kuqinisekisa ukukhutshwa okuzinzileyo, okulawulwayo kwechiza ixesha elide, ngaloo ndlela kuphuculwe ukuthotyelwa kwesigulane.
C. Umenzeli wokugquma ifilimu:
I-HPMC E15 isetyenziswa njengefilimu yangaphambili yethebhulethi kunye neepilisi zokwaleka.Ifilimu ephumelayo ikhusela iyeza kwizinto ezisingqongileyo, iphucula ukubonakala kwaye iququzelele ukuginya.
D. Iarhente yokunqumamisa:
Kwimixube yomlomo engamanzi, i-HPMC E15 isebenza njenge-arhente yokumisa, ukuthintela ukuhlaliswa kwamasuntswana kunye nokuqinisekisa ukuhanjiswa okufanayo kwechiza kulo lonke ulwelo.
E. Thickener:
Iimpawu zayo zokuguqula i-viscosity yenza i-HPMC E15 ixabiseke njenge-thickener kulwelo kunye ne-semi-solid formulations efana nejeli kunye neekhrimu, inceda ekuphuculeni uzinzo kunye nokulula ukusetyenziswa.
F. Disintegrant:
Kwimiqulu ethile, i-HPMC E15 inokusebenza njenge-disintegrant, ikhuthaza ithebhulethi ukuba ihlehlise ngokukhawuleza ibe ngamancinci amancinci xa idibana namanzi, ikhuthaza ukukhutshwa kweziyobisi kunye nokufunxa.
G. Emulsion stabilizer:
Kwizinto ezixutywayo ezifana ne-creams kunye ne-lotions, i-HPMC E15 isebenza njenge-stabilizer kwi-emulsions, ukukhusela ukuhlukana kwesigaba kunye nokwandisa ukuzinza okupheleleyo kwemveliso.
H. Iipeyilethi zokukhulula ezizinzileyo:
I-HPMC E15 ikwasetyenziselwa ukuvelisa iipellets zokukhulula ezandisiweyo ezibonelela ngeprofayili yokukhutshwa kwechiza elilawulwayo xa lilawulwa ngomlomo.
4. Ezinye izicelo:
A. Ifomula yokuthambisa:
Kwizinto zokuthambisa, i-HPMC E15 isetyenziswa kwiimveliso ezahlukeneyo ezibandakanya iikhrimu, iiloshini kunye neeshampu ukunceda ukuphucula ukuthungwa, ukuzinza kunye nokusebenza ngokubanzi kweefomyula.
B. Ishishini lokutya:
I-HPMC E15 ngamanye amaxesha isetyenziswa kushishino lokutya njengento etyebisayo, isizinzisi okanye i-emulsifier kwiimveliso ezifana neesosi, izinxibo kunye neempahla ezibhakiweyo.
C. Ushishino lokwakha:
Kwishishini lokwakha, i-HPMC E15 isetyenziswa njengesongezo kwiimveliso ezisekelwe kwisamente ukuphucula ukusebenza, ukubambelela kunye nokugcinwa kwamanzi.
I-HPMC E15 yi-excipient eguquguqukayo kwaye eyimfuneko enoluhlu olubanzi lwezicelo, ngakumbi kushishino lwamayeza.Indima yayo njengesibophelelo, i-matrix yangaphambili, i-ejenti yokugquma ifilimu, kunye neminye imisebenzi eyahlukahlukeneyo iyenza ibe sisithako esiphambili kuqulunqo lwefomu yedosi yomlomo.Ukongeza kumachiza, ukusetyenziswa kwayo kwandisa izimonyo, ukutya kunye namashishini okwakha, kubonisa ukulungelelaniswa nokubaluleka kwayo kwizicelo ezahlukeneyo.Njengoko uphando kunye nophuhliso kule mimandla luqhubeka, i-HPMC E15 kusenokwenzeka ukuba ihlale ingumdlali ophambili kumashishini afuna iindlela eziphuculweyo zokuhanjiswa kweziyobisi, ukwakheka okuzinzileyo kunye nokusebenza kwemveliso okongeziweyo.
