Hydroxypropyl methylcelculose (hpmc)sisixhobo esinyibiliki esinyibilikayo esivela kwi-selsulose yendalo kwaye isetyenziswa ngokubanzi kwiimveliso ezahlukeneyo zonyango, ii-cosmetics kunye neemveliso zamachiza. NjengeSellUlose eguqulweyo, ayisetyenziswanga ngokubanzi kumzi mveliso, kodwa idlale iindima ezininzi kwiimveliso zonyango.
I-1. Amantshontsho kunye nezilotha
I-HydroxyPOpyl Methylcelcelse i-thickener esebenzayo enokuthi inyuse kakhulu i-vickosity yeemveliso zonyango kwaye incedise imveliso yenze i-fortal efanelekileyo. Ihlala yongezwa kwi-outs, iikhrim, abahlambuluki bobuso kunye nezinye iimveliso ukuba zinike i-viscofity ephakathi, ekungekho lula kuphela ukuba isebenze, kodwa iphucula ukusetyenziswa nentuthuzelo yemveliso.
Ukongeza, isiphumo sokuqaqamba kwe-HPMC kwifomula kunceda ukuzinzisa isakhiwo se-emulsion, thintela ukubekwa ngokwahlula-hlula okanye ukwahlulwa kwamanzi, kwaye kwandise ubomi bemveliso. Ngokwandisa i-viscofity kwifomula, yenza ukuba intsebenzo phakathi kwesigaba samanzi kunye nesigaba seoyile sizinzileyo, ngaloo ndlela isisiseko seoyile sizinzileyo, ngaloo ndlela sizinzileyo, apho ke siyakuqinisekisa ukufana kweemveliso kunye neekhrim.
2. Isiphumo sokunyathela
I-HydroxyPOpyl Methylcelcelgalose inomzimba olungileyo, kwaye iimolekyuli zayo zinemigangatho ye-hydrophilic ezinokwenza iibhondi ze-hydrogen ezinemolekyuli zamanzi ukunceda ukugcina umswakama. I-HPMC ayidlala kuphela indima yokuthathwa kweemveliso zonyango, kodwa ikwatha kwaye itshixiwe kukufuma, ukubonelela ngeziphumo zexesha elide zokunyangwa. Oku kuluncedo kakhulu kolusu olomileyo okanye ukomisa ulusu lolusu, ukugcina ulusu luhlanjwe.
Kwezinye iikhrim kunye nezilonda eziqulathe i-hydroxypropyl methylceluplose, ifuthe eliyiswayo lokuthintela ukuntywila liphucule, lishiya ulusu luziva luthambile, luthambile kwaye luqinile kwaye luqinile.
3. Ukuphucula ulusu kwaye uchukumise
Ukusukela ukuba i-HPMC ye-HPMC inomgangatho othile wokuguquguquka, inokuphucula kakhulu uziva iimveliso zonyango, zibethe gwenxa kwaye zibuthathaka ngakumbi. Ngexesha lokusetyenziswa, i-Hydroxypropyl Methylcelceltulose inokubonelela ngemveliso kunye nesilika esifungukayo, ukuze ulusu aluzivanga okanye lubekwe ngokukhawuleza emva kokuzihlaziya kunye nokugcina iziphumo.
Olu phuculo luqapheni yinto ebaluleke kakhulu kubathengi, ngakumbi abasebenzisi abanenkxalabo enobuthathaka okanye onamafutha, apho baziva khona ngexesha lokusetyenziswa kubaluleke kakhulu.
4. Lawula ulwelo kunye nokusasazeka kwefomula
Isiphumo sokuthambisaI-HPMCAyisiyonyani nje iMveliso i-mveliso, kodwa ilawula ulwelo lwemveliso, eyenza ilungele ukusetyenziswa. Ingakumbi i-lotion kunye neemveliso zejeli, ukusetyenziswa kwe-hydroxypropyl methylcelcelcelose inokuphucula ukufana kwesicelo, ukuvumela imveliso ukuba isasazeke kakhulu kulusu okanye inkunkuma.
Kwezinye i-crems enye okanye iimveliso zononophelo, ukongezwa kwe-hydroxyproplol methylcelcelose kunokuphucula ngokufanelekileyo ukuthotyelwa kwesicelo, ukuvumela imveliso isetyenziswa ngokufanelekileyo kwiindawo ezinobunzima.
I-5. Njengommeli wokumiselwa
I-HydroxyPOpyl Methylcelceltulose idla ngokusetyenziswa njengearhente yokumisa kwiimveliso zonyango, ngakumbi ezo zithatyatho ezisebenzayo okanye izithako zegranure. Inokuthintela ngokufanelekileyo ukuqina okanye ukwahlukana kwezithako eziqinileyo (ezinjengamasuntswana emithurali, izityalo, njl.njl), kuqinisekiswe ukuba zonke izithako ezisasazwe, kwaye zithintele ekusebenziseni impumelelo kwimveliso yemveliso okanye ukuhombisa.
Umzekelo, kwezinye iimaski zobuso eziqukethe amasuntswana okanye izityalo, i-HPMC inokunceda ukugcina ulwabiwo lwamasuntswana, ngaloo ndlela kuphuculwe ukusebenza kwemveliso.
I-6. Ukungakhathali kwaye kungacaphuki
Njengesithako esikhutshiweyo kwi-seluplose yendalo, i-Hydroxypropyl Methylcelcelcelose ine-biomatining elungileyo kunye neHypoalgejiniisity, ngoko kufanelekile kuzo zonke iintlobo zolusu, ngakumbi ulusu olunolusu. Ubulali bayo buyenza ikhuseleke ukuba isebenzise kwiimveliso zonyango ngaphandle kokubangela ukucaphukisa okanye ukungonwabisi kulusu.
Olu phawu lwenza i-HPMC i-HPMC isithako esithandwayo kwiimpawu ezininzi xa kuphuhliswa iimveliso zolusu olunolusu, ukhathalelo lolusu, kunye neemveliso zasimahla.
7. Ukuphucula imisebenzi ye-antioxidant kunye ne-anti-ungcoliseko
Olunye uphononongo lubonise ukuba ubume bemolekyuli ye-HydroxyPOpyl Methylcelceluplose, i-seluplose yendalo inika indalo, inokubonelela ngokhuseleko lwe-antioxidant kunye nongcoliseko longcoliseko. Kwiimveliso zononophelo lolusu, inokusetyenziswa ngokudibeneyo nezinye izithako ze-Antioxidant (njengeVitamin C, iVitamin E, njl.njl) ukunceda ukususa i-radicals yasimahla. Ukongeza, ubume be-hppmcrophil bunokukunceda ukukhusela ulusu kubangcoliseka emoyeni.
Hydroxypropyl methylcelceluploseIdlala indima eninzi kwiimveliso zononophelo lolusu. Ayinakusebenza kuphela njengendawo enkulu yokuphucula ukuthungwa kunye nokuziva imveliso, kodwa ikwanemisebenzi ebalulekileyo efana nokuthatyathwa, ukuphucula ulusu, kunye nokulawula ulwalamano. Njengobuncinci obuthongo olunobulali, kufanelekile, inokuphucula ukusebenza kweemveliso zonyango kunye namava abasebenzisi. Isetyenziswe ngokubanzi kwiimveliso ezahlukeneyo zonyango ezinje ngemikhono yobuso, i-otions, abahlambulisi kunye nemaski yobuso. Njengoko imfuno yezithako zendalo kunye neemveliso zenkathalo yolusu yolusu ziqhubeka nokunyuka, i-Hydroxypropyl MethylcelceLcelose iya kuqhubeka nokudlala indima ebalulekileyo kuphuhliso lwemveliso yonyango lwexesha elizayo.
