Umahluko phakathi kweBanga le-HPMC yeBanga le-HPMC kunye noKhathalelo loMntu kwiBanga le-HPMC

I-Hydroxypropyl Methylcelcelsele (i-HPMC) yi-polymer eguquguqukayo ngoluhlu olubanzi lwezicelo kumashishini ahlukeneyo kubandakanya nokhathalelo, ukutya kunye nokhathalelo lobuqu. Kwicandelo lezokwakha, i-HPMC idla ngokusetyenziswa njenge-thi checker, i-binder kunye ne-emulsifier kwiimveliso ezisekwe kwisamente. Kumzi-mveliso wokhathalelo lobuqu, i-HPMC isetyenziswa njengesithanga kwizinto ezininzi ze-cosmetics ngenxa yokwakha ifilimu yefilimu kunye neepropathi zokuqhuba.

Nangona kunjalo, ayizizo zonke iimveliso ze-HPMC zenziwe ngokulinganayo. Kuxhomekeka kwinkqubo yokwenziwa kunye nemigangatho esemgangathweni, i-HPMC inokwahlulwa ibe ngamabanga ahlukeneyo: Ibakala lokwakha kunye nenqanaba lononophelo lomntu. Kweli nqaku, siza kuthetha ngomahluko phakathi kwala mabakala amabini kwi-HPMC.

I-1. Inkqubo yokuFumana:

Inkqubo yokuphucula iBakala HPMC iqala ngokukhupha i-selsulose ukusuka kwi-selupes kwi-pulp okanye i-cotton ezine. Nje ukuba i-seluplose ikhutshelwe, iqhubekile ukuba ivelise i-HPMC. Nangona kunjalo, umahluko phakathi kwala mabanga amabini ubuxoki kwinqanaba lokucocwa nokusetyenziswa kwezibalo.

I-HPMC yeBanga le-HPMC iveliswa ngokusebenzisa iinkqubo ezilula nexabiso elinendleko ezibandakanya ukucocwa okuncinci. Olu hlobo lwe-HPMC lusetyenziswa ikakhulu kwiimveliso zokwakha apho iimfuno zokucoceka aziphezulu.

I-HPMC yakho yeBanga le-HPMC, kwelinye icala, iphantsi kwenkqubo yokuCoca okungakumbi ukuqinisekisa ubunyulu obuphezulu. I-HPMC yoKhathalelo ye-HPMC ihlala ihlolwe izinyithi ezinzima, i-microorganisms, kunye nezinye izinto zokungcola zokufezekisa ukhuseleko olungqongqo ukufezekisa ishishini lokhathalelo lobuqu.

I-2. Ukucoceka kunye nemigangatho esemgangathweni:

I-HPMC ye-HPMC yokwakha inezantsi kunye nemigangatho esemgangathweni kunenqanaba lononophelo lwe-HPMC. I-HPMC ye-HPMC yokwakha isetyenziswa ngokweemveliso apho ukucoceka khona kubaluleke kakhulu, ezinjengeemveliso ezisekwe kwisamente, iimveliso ze-gypsum, kunye ne-tile. Ezi mveliso azilungelanga ukusetyenziswa ngabantu, ngoko ke imigangatho yokucoceka iyamkeleka.

I-HPMC yakho ye-HPMC, kwelinye icala, iphantsi kococeko olungqongqo kunye nemigangatho esemgangathweni. Iimveliso zononophelo lobuqu, ezinjengeShampoos, ii-lotions kunye neekhrim, zenzelwe ukuba zisetyenziswe kulusu okanye kwiinwele, kwaye, kwezinye iimeko, zingeniswe ngumzimba. Ke ngoko, ubunyulu bamathako asetyenzisiweyo kwezi mveliso kubalulekile ukuthintela naziphi na iziphumo ezibi kwimpilo yomsebenzisi.

I-3. Ukuvunywa kolawulo:

I-HPMC yeBanga le-HPMC iqhele ayifuni imvume ebanzi yolawulo kuba ayilungelanga ukusetyenziswa ngabantu. Nangona kunjalo, ezinye iiarhente ezilawulayo zinokufuna abavelisi ukuba banike iphepha ledatha lokhuseleko (i-SDS) kwiimveliso zabo, ezichaza ubungozi bemveliso enokubakho kunye nezilumkiso zokhuseleko.

Ngokwahlukileyo, i-HPMC yobuqu i-HPMC ifuna imvume ebanzi yolawulo, kuxhomekeka kwilizwe kunye nengingqi ekuyenzelwa ukuba kuthengiswe kuwo. Iiarhente ezilawulayo ezinjengokulawulwa kwe-US kunye nolawulo lweziyobisi (i-FDA) zifuna abavelisi ukuba baqhube izifundo zokhuseleko kunye nokusebenza kakuhle ngaphambi kokuba bavume iimveliso zabo zononophelo.

4. Isicelo:

I-HPMC ye-HPMC yokwakha ilungele uluhlu olubanzi lwezicelo kwishishini lokwakha. Ihlala isetyenziswa njengearhente ye-thi checkener kunye nokugcina amanzi kwiimveliso ezisekwe kwimo yesamente ezinjengokufa, i-griuts, kunye nekhonkrithi. I-HPMC ikwasebenza njenge-Binder entle kunye ne-emulsifier kwiimveliso ze-gypsim ezinje nge-quages ​​edibeneyo kwaye igqitywe.

Kwelinye icala, i-HPMC yoKhathalelo ye-HPMC isetyenziswa ikakhulu njengezithako ze-cosmetic, ezinje ngononophelo lweenwele, ukhathalelo lolusu kunye neemveliso zononophelo ngomlomo. Yifilimu egqwesileyo yangaphambili kunye ne-tickener, i-geses kunye ne-emulsion ezizinzileyo. I-HPMC ikwasetyenziswa njenge-sonclor yohlengahlengiso ukubonelela ngokugudileyo, i-silky ivakalelwa kwiifomula zononophelo zobuqu.

Umahluko phakathi kwenqanaba lokhathalelo lwebanga kunye nenqanaba lobuqu le-HPMC ngumgangatho wokucocwa, imigangatho esemgangathweni, imvume yolawulo kunye nesicelo. I-HPMC ye-HPMC ye-HPMC ilungele iimveliso ezingezizo zabantu apho iimfuno zokucoceka aziphezulu. I-HPMC yoKhathalelo yeBanga le-HPMC ilandela umgangatho ongqongqo kunye nemigangatho yokucoceka ukuqinisekisa ukhuseleko lomsebenzisi wokugqibela. Kubalulekile ukuba uqonde umahluko phakathi kwala manqanaba mabini e-HPMC, njengoko usebenzisa inqanaba elingalunganga kunokubangela ukusebenza kwezempilo okanye ukusebenza kakuhle.
