Ngaba i-HPMC Hydrophilic okanye i-lipophilic?

I-Hydroxypropyl Methylcelcelsulose ye-Polymer esetyenziswe ngokubanzi kunye nezicelo ezahlukeneyo zezamayeza, ukutya, i-cosmetics nolwakhiwo. Umbuzo we-hydrophicicicity kunye ne-lipophility ye-HPMC ikakhulu ixhomekeke kwimo yayo yemichiza kunye neepropathi zemolekyuli.

Isakhiwo sekhemikhali kunye neepropathi ze-HPMC
I-HPMC yi-ionic se-unic selsulose eyenziwe ngokwazisa i-hydroxypropyl kunye namaqela e-methyl kwimo yemolekyuli yeselselose. I-molecular ye-molecular iqulethe i-hydroxyl ye-hydroxyl (-) kunye ne-lipophilic (-C3) kunye ne-hydroxylpropyl (-oh) amaqela. Ke ngoko, inezixhobo ezibini, zombini i-hydrophilic kunye ne-lipophilic, kodwa i-hydrophility ilawula kancinci. Le ndawo inika i-Iloubaility elungileyo, ukwenza ifilimu kunye nezinto ezinamatyala, kwaye zinokwenza ukusasazeka okuzinzileyo kwizisombululo ezizezinzi kunye nezinyibilikisi eziphilayo.

I-hydrophility ye-HPMC
Ngenxa yenani elikhulu lamaqela e-hydroxyl kwisakhiwo se-HPMC, i-molecular ye-molecular inee-hydrophiility ezomeleleyo. Emanzini, i-HPMC inokwenza iibhondi ze-hydrogen, ivumela iimolekyuli zokunyibilika emanzini kwaye zenze isisombululo se-viscofity ephezulu. Ukongeza, i-HPMC ikwanokugcinwa kwamanzi ahle kakhulu kwaye isetyenziswa ngokubanzi njenge-thi cokener kunye ne-stabilizer kwi-Medic, ukutya kunye ne-cosmetics. Umzekelo, i-HPMC inokusetyenziswa njenge-arhente yokukhupha okuzinzileyo kumalungiselelo amachiza ukulibazisa inani lokukhupha iziyobisi emzimbeni kwaye liphucule uzinzo olusebenza kakuhle.

I-Lipophility ye-HPMC
I-methyl kunye namaqela e-hydroxypropy kwi-HPMC Molecule inee-hydrophobizetion ezithile, i-HPMC ikwane-lipophility etho tyheli, ngakumbi kwizisombululo eziphantsi okanye eziphilayo ukwenza isisombululo esizinzileyo. I-Lipophiliicity yayo inceda ukuba ixube kunye nezinto zesigaba zeoyile, eziphucula amandla e-HPMC kwi-eul-amanzi in-in-in-in-in-in-in-in-in-in-in-in-in-in-in-in-in-in-in-in-in-in-in-in-in-in-ter. Kwezinye ii-emulssions okanye izilungiso ezihlanganisiweyo, i-lipophility ye-HPMC inceda ekwenzeni inkqubo engapheliyo ye-hydrophoby, ngaloo ndlela isebenzela ukuhanjiswa kunye nokuzinza kwezithako.

Ukusetyenziswa kwe-HPMC
Amalungiselelo amachiza amayeza: I-HPMC ihlala isetyenziswa njengokukhutshwa kwezinto ezigciniweyo ezizinzileyo kwiitafile, kusetyenziswa iipropathi zayo zefilimu zokulawula inqanaba lokukhupha iziyobisi.
Umzi-mveliso wokutya: Ukutya, i-HPMC isetyenziswa njenge-thickener kunye ne-RETMERER kunye nokugcina amanzi ukuze kwandise ubomi beshelufu yokutya kwaye uphucule incasa.
Izinto zokwakha: Ukuzenzela amanzi e-HPMMC kunye nefutha le-HPMMC elenza i-chickener yodaka ekwakhiweni, ukuphucula ukusebenza kunye namanzi abambe amandla okwenza izinto.
I-cosmetics: kwiimveliso zononophelo lolusu, i-HPMC inokusetyenziswa njengesiqhelo se-emlsifier stabilizer. Ngenxa yokungabikho kwe-hydrophicicity, ingenza i-matrix ye-actrix ukugcina isiphumo sokunyanyezwa kunye nokubekwa kwemveliso.
I-HPMC yi-Ampyorshilic Polymer ye-Polymer ye-hydrophilic kunye ne-lipophilic, kodwa kuba inamaqela e-hydroxyl, ibonakalisa i-hydrophicicicty eyomeleleyo.
