(I-HPMC) Yintoni umahluko kunye okanye ngaphandle kwezi?

Kubonakala ngathi ubhekisa kuHydroxypropyl methylcelculose (hpmc), i-polymer esetyenziswe ngokubanzi kwimizi-mveliso eyahlukeneyo kubandakanya amayeza, uKwakha, ukutya kunye ne-cosmetics. Umahluko phakathi kwe-HPMC kunye kwaye ngaphandle kweleta 'inokuthi ngokukodwa kumabakala ahlukeneyo, ukwenziwa kwayo, okanye iimveliso ezithile.

I-HydroxyPOpyl Methylcelcelsulose (HPMC) yi-semi-synthetic, i-InErt, i-villmelastic polymer ethathwe kwi-sellulose. Kudala kuveliswa ngokutshintsha kweekhemikhali kweselphulelo, ebandakanya ukuphatha i-sellulose nealkali kunye ne-propylene oxide ukuba ingenise i-hydroxyl kunye namaqela e-methyl.

Nazi ezinye iindawo eziphambili malunga ne-HPMC:

Isakhiwo sekhemikhali: I-HPMC iqulethe imixokelelwane emide yeeyunithi ze-glucose ene-hydroxypropy kunye namaqela e-methyl aqhotyoshelwe amaqela e-hydroxyl (---). Umyinge wale nto unokutshintsha, ukhokela kumabakala ahlukeneyo e-HPMC enezinto ezahlukeneyo.

Iipropathi zomzimba: i-HPMC kukunyibilika kwamanzi kunye neefom ezibonakalayo, izisombululo ze-viscous zinyibilikisiwe emanzini. U-Viscosity wayo unokulawulwa ngokuhlengahlengisa iiparameter ezifana nobunzima bemolekyuli, isidanga sokufaka kunye nokugxininisa.

Izicelo:

I-Phamaceuticals: I-HPMC isetyenziswa ngokusetyenziswa kwifomu yamayeza njenge-thi chuler, i-binder, ifilimu yangaphambili, kunye ne-Arhente yokuGqibela-khupha iArhente kwiitafile, iicapbules, kunye neefomu eziphezulu.
Ulwakhiwo: Kwizinto zokwakha ezifana nokufa, ukuhambisa, kunye ne-Tile Abest, i-HPMC iphucula ukusebenza ngokukuko, ukugcinwa kwamanzi, kunye nokunamathela amanzi.
Ukutya: I-HPMC isetyenziswa kwiimveliso zokutya njenge-gickener, i-stabilizer, kunye ne-mulsifier. Ihlala ifumaneka kwiimveliso zobisi, iisosi kunye needessert.
I-Cosmetics: i-HPMC ibandakanyiwe kwi-cosmetics kunye neemveliso zononophelo zobuqu njengeekhreyimu, i-lotions, kunye ne-shampoos ukomeleza ukuthunyelwa, uzinzo, kunye neepropathi zokwenza ifilimu.

Izibonelelo:

I-HPMC inika amabala okugcinwa kwamanzi, ebaluleke kakhulu kwizicelo ezifana nokufakelwa kwemitha yesamente apho kufuneka hydration ixesha elide kufuneka anyangwe.
Iphucula ububi kunye nokusebenza kwizixhobo zokwakha, igalelo kwintsebenzo engcono kunye nokuqina.
Kwi-Hermemaceuticals, i-HPMC iqhuba ukukhutshwa ngamachiza okulawulekayo kunye nokuphucula iipropathi ze-facturty.
I-HPMC ithathwa njengekhuselekileyo ekusetyenzisweni kwaye yamkelwe ngokubanzi kukutya kunye neemveliso zecosmetic.
Amabakala kunye neenkcukacha: I-HPMC iyafumaneka kumabakala ahlukeneyo kunye neenkcazo ezilungiselelwe izicelo ezithile. Oku kubandakanya umahluko kwi-viscofity, ubungakanani bentsumpa, inqanaba lokufakwa, kunye nezinye iiparamitha ukuze ufezekise iimfuno zamashishini ahlukeneyo kunye nefomu.

Imeko yokulawula: I-HPMC iqatshelwa njengezigunyazisi ezikhuselekileyo ezifana nolawulo olunjengokutya kwe-US kunye nolawulo lweziyobisi (i-FDA) xa isetyenziswa ngokuhambelana nezenzo ezifanelekileyo zemveliso.

I-HPMC yi-polymer eguquguqukayo ngezicelo ezahlukileyo kumashishini. Iipropathi zayo zinokulungelelaniswa ukuba zihlangabezane neemfuno ezithile, zisenza isithako esixabisekileyo kwiifom kunye neemveliso ezahlukeneyo. Ukuba unolwazi olukhethekileyo malunga ne-HPMC nge okanye ngaphandle kweleta ', nceda unike umxholo ongezelelweyo wengcaciso eyongezelelweyo.
