Iipilisi zezityalo ezisetyenziswa kwiimveliso zethu ezenziweyo zenziwe nge-hydroxypropylmethylcellulose (HPMC), eyaziwa ngokuba yi-hydroxypropylmethylcellulose. Ngoku, kwixesha elidlulileyo, bekunokwenzeka ukudwelisa le mixholo kwileyibhile:
Ezinye izithako:iicapsules zezityalo (ifayibha yezityalo kunye namanzi)
Kodwa ke i-FDA yatshintsha imimiselo yokuleyibhile ukuze ifune iminqwazi yemifuno ukuba zidweliswe njenge-hydroxypropyl methylcellulose okanye i-hydroxypropyl methylcellulose.
Ngoko ke, kufuneka kuqatshelwe kuqala ukuba i-hydroxypropyl methylcellulose phthalate (HPMCP) yinto eyahlukileyo kwi-HPMC ngqo (i-hydroxypropyl methylcellulose okanye i-hydroxypropyl methylcellulose). Ewe, eli gama lizisa umahluko omkhulu.
Ngokwetheyibhile echaziweyo yomenzi weminqwazi yemifuno:
I-HPMC yimveliso yesityalo eluhlobo olusulungekileyo lweselulosi ekhutshwe kwintlama yomthi. Ngokutsho kweSihlomelo I se-EU Regulation No. 1169/2011 ekuboneleleni ngolwazi lokutya kubathengi, i-HPMC ihlelwa njenge "fiber" kwaye ichazwa njengepolymer yeekhompawundi zamanzi ekhabhoni ezineeyunithi ezintathu okanye ngaphezulu ze-monomer, ezingatyiswanga okanye zifunxelwe amathumbu amancinci omntu.
Nangona kunjalo, iindlela zangoku zovavanyo lwelabhoratri yefiber yokutya, njenge-AOAC 985.29, ayiboni ngokuchanekileyo i-HPMC njengefiber yokutya. Nangona kunjalo, i-HPMC i-polymer ye-carbohydrate edliwayo, i-fiber yokutya enenzuzo ye-physiological effects, eye yamkelwa ngokubanzi ngobungqina besayensi, kwaye ngoko inokubhengezwa ngokuzithandela.
Kulabo abangafundanga kakhulu i-chemistry
ICellulose litsheyini elenziwe yikhabhoni, ihydrogen, kunye neoksijini, ebandakanya amakhulu ukuya kumawaka ekhabhoni, ihydrogen, kunye nekhonkco leoksijini kunye.
IHydroxyl - ithetha ukuba kukho ioksijini kunye nehydrogen edityaniswe kwindawo ethile kwikhonkco leselulosi, kunokuba nje ihydrogen.
Ipropyl - kuthetha ukuba kukho ikhonkco elisecaleni kwindawo ethile kwikhonkco, apho iiathom ezintathu zekhabhoni zijikelezwe yi-hydrogen.
I-Methyl - Ifana nepropyl, kodwa kungekhona iikhabhoni ezintathu, kodwa enye kuphela.
Hlanganisa ezi zinto zine kwaye uya kufumana=hydroxypropyl methylcellulose
Ukuze uhlolisise ngokucokisekileyo olu lwazi kwaye uqinisekise ukuba akukho mxholo oye wahoywa okanye uhlotshiswe, ndihlolisise ukuba uDkt Joseph Mercola (ugqirha oyinyaniso kunye nesethi epheleleyo yabaphandi bexesha elizeleyo) ubhale amanqaku kwi-hydroxypropyl methylcellulose. Hayi ndiye ndajonga ezakhe iSupplements ukuba zenziwa ngantoni i capsules zakhe. Ewe, zidweliswe phantsi 'kwezinye izithako: Hydroxypropylmethylcellulose'.
Ngoko ke ndicinga ukuba sinokutsho ngokuqinisekileyo ukuba eyona nto iphambili kukuba i-hydroxypropyl methylcellulose yi-fiber yokutya esekelwe kwisityalo.
Elinye icandelo elihlala livela kwizongezo zethu yihydroxypropyl methylcellulose, edla ngokusetyenziswa ukwenza iicapsules.
IHydroxypropylmethylcellulose idla ngokuthathwa kwiplanti cellulose, eyicarbohydrate efumaneka kwiindonga zeeseli zesityalo. Le khompawundi ethile isetyenziswa ngokuqhelekileyo ekwenzeni iipilisi zemifuno.
I-Hydroxypropylmethylcellulose ngokuqhelekileyo ibonakala ngendlela ye-hydroxypropylmethylcellulose okanye i-HPMC kuluhlu lwezithako, ezifana "nepowder yomlingo".
Imvelaphi yezityalo, xa ixutywe kwimveliso, inokwenza imveliso ibe nzima, iqinisekise ukuthungwa okugudileyo, kwaye yenza ukuba umphumo wayo ube yinto ehlala njalo.
Iyabonakala kwaye incamathele xa imanzi, iyenza ibeyinto eqhelekileyo kumashishini amaninzi, ngakumbi kuba ithambile emizimbeni yethu kwaye ithathwa njengenobuhlobo nokusingqongileyo.
Yenziwa njani ihydroxypropyl methylcellulose?
Ukugcina ubulula kunye nokucaca, ndiza kwazisa ngokufutshane isigaba ngasinye kwezi zilandelayo:
- Ukutsalwa kwemathiriyeli ekrwada: Eyona mathiriyeli ekrwada ye-hydroxypropyl methylcellulose sisityalo se-cellulose, esihlala siphuma kwintlama yeplanga okanye kwilaphu yomqhaphu.
- Unyango lwe-alkali: Nyanga i-cellulose ngesisombululo esinamandla sealkaline (njengesodium hydroxide) ukuyijika ibe yi-alkaline cellulose.
- I-Methylation: Kule nyathelo, i-alkaline cellulose iphathwa nge-methyl chloride ukwazisa amaqela e-methyl kwiimolekyuli ze-cellulose.
- IHydroxypropylation: Kulapho ihydroxypropyl yaziswa khona. I-Methylcellulose iphendula kunye ne-epoxy propane, okubangela ukudibanisa kwamaqela e-hydroxypropyl.
- Ukucocwa: Emva koko uhlambulule i-hydroxypropyl methylcellulose efunyenweyo ukususa nayiphi na imichiza engaphendulwanga kunye nobunye ukungcola. Oku kudla ngokuquka ukuhlamba, ukuhluza, nokomisa.
- Ukugaya kunye ne-granulation: Ekugqibeleni, i-hydroxypropyl methylcellulose eyomileyo igayiwe ibe ngumgubo ocolekileyo kwaye inokuthi ifakwe i-granulated ukuze ifumane ubungakanani obufunekayo obufunekayo kwisicelo sayo.
Iqondo le-methylation kunye ne-hydroxypropylation inokulawulwa ngexesha lenkqubo yokuvelisa, eya kuchaphazela ukunyibilika kunye neempawu ze-viscosity ze-hydroxypropylmethylcellulose efunyenweyo.
Lo matshini uvumela abavelisi ukuba balungelelanise iimpawu zabo kwizicelo ezithile ukuhlangabezana neemfuno zeemveliso ezahlukeneyo.
Ngaba ngokwenene i-hydroxypropyl methylcellulose inosetyenziso oluninzi?
Ewe, sisithako esisebenza ngeendlela ezininzi esidlala indima kumashishini amaninzi, kwaye kukho imizekelo emininzi. Enyanisweni, enye yazo ikhankanywe ekuqaleni kweli nqaku.
Makhe sithethe ngayo ngoshishino.
- Kwishishini lamachiza.
Amacwecwe okukhululwa okuzinzileyo: I-Hydroxypropylmethylcellulose isetyenziselwa ukuqulunqa iipilisi ukulawula izinga lokukhululwa kwezithako ezisebenzayo zonyango kunye nokuqinisekisa ukukhululwa kweziyobisi ixesha elide.
Amathontsi eliso: Asetyenziswa njengeenyembezi ezenziweyo kumalungiselelo e-ophthalmic ukuthomalalisa iimpawu zamehlo omileyo.
I-ejenti yokugubungela: Iipropati zayo zokwenza ifilimu zivumela ukuba zisetyenziswe njenge-agent yokugqoka iipilisi kunye neepilisi, ukuphucula ukuzinza kunye nokubonakala.
- Kwishishini lokutya.
I-Thickener kunye ne-stabilizer: I-Hydroxypropylmethylcellulose yongezwa kwizinto ezahlukeneyo zokutya, ezifana ne-sauces, i-dessert, kunye nempahla ebhakiweyo, ukufezekisa ukuhambelana okufunwayo okanye ukuthungwa.
I-Vegetarian substitute: Iyindawo eyaziwayo ye-gelatin ekudleni kwemifuno okanye ukutya kwemifuno, kuba inika ukuhambelana okufana nejel, kwaye ayinayo izithako zemvelaphi yezilwanyana.
I-Ceramic tile adhesive kunye ne-plaster: I-Hydroxypropylmethylcellulose isetyenziswe njenge-agent egcina amanzi ukuze kuqinisekiswe ukomisa okuhambelanayo kunye nokuphucula ukuqhutyelwa phambili.
- Kwizinto zokuthambisa.
I-Thickener kwi-lotion kunye nekhrimu yobuso: Ibonelela ngobume obugudileyo kunye nokuhambelana kwezinto zokuthambisa.
Ikwanazo nezinye izicelo ezithile.
- Imveliso ye-inki: isetyenziswa njenge-thickener kunye ne-stabilizer.
- Ezolimo: Isetyenziswa njengesibophelelo kwimbewu yegranular.
- Umzi-mveliso welaphu: isetyenziselwa ukwenza imilinganiselo yelaphu ukomeleza umsonto ngexesha lenkqubo yokuluka.
Eminye imibuzo eqhelekileyo
- Ngaba i-hydroxypropyl methylcellulose inokutyiwa ngokukhuselekileyo?
Ewe, i-hydroxypropyl methylcellulose ngokuqhelekileyo ithathwa njengekhuselekile ukuba ingasetyenziswa kwaye yamkelwe ukuba isetyenziswe ekutyeni zii-arhente ezininzi ezilawulayo kwihlabathi liphela.
- Ngaba i-hydroxypropyl methylcellulose iyabola?
Ewe, njenge-cellulose ephuma kwi-cellulose, i-hydroxypropylmethylcellulose i-biodegradable, eyenza ukuba ikhuseleke ngakumbi kokusingqongileyo xa kuthelekiswa nezinye iipolymers zokwenziwa.
- Kutheni usebenzisa i-hydroxypropyl methylcellulose kumathontsi esweni?
I-Hydroxypropylmethylcellulose inokulinganisa iimpawu zeenyembezi zendalo, inika i-lubrication kunye nokukhululeka kwamehlo omileyo kunye ne-astringent. Iimpawu zayo ze-viscous zinceda ukuba zihlale phezu kwamehlo ixesha elide kunamanzi, zinika umphumo wokunceda ixesha elide.
