I-Cosmetic Inqanaba le-HydroxyPOpyl MethylcelcelUlose ye-HETMELCE (i-HPMC) yindawo eguquguqukayo esetyenziswe kumashishini ahlukeneyo kubandakanya i-cosmetics, iingcingo zononophelo kunye neemveliso zononophelo. Yinto engu-ionic selsulose i-ether ye-Ether iphulukenelwe ngokutshintsha kweekhemikhali kwe-sellutase yendalo. I-HPMC yindawo efudumeleyo ye-methylcelcelculose (mc) equlethe amaqela asebenza e-hydroxypropy enika ipropathi eyahlukileyo efana nokugcinwa kwamanzi, kunye nokwenza ubumbi bokwenza ifilimu.
I-HPMMC ye-HOSMMC yi-polymer yenqanaba lokutya eliyibhayisikile kwaye ikhuselekile ukuze isetyenziswe kwizicelo ezahlukeneyo, kubandakanya njengamanzi amakhulu, ukuzinza, ii-arhente kunye nee-agers. Inyibilika ngokulula emanzini, kwaye i-viscofity yayo inokuhlengahlengiswa ngokutshintsha isidanga sayo yokufakelwa (DS) kunye nobunzima bemoyara yePolymer.
Kumzi-mveliso we-cosmetics, i-HPMC ye-HEMMC ye-HPMC isetyenziswa njenge-tickener kunye ne-binder kwiimveliso zonyango ezinjengeekhrim, i-lotions, kunye ne-gels. Inceda ukudala ubume obuthambileyo, obungapheliyo kwaye bonyusa amandla emveliso yemveliso. I-HPMC ikwaphucula ukwaliwa kweemveliso, kubenza kube lula ukusasazeka kulusu.
Kwiimveliso zokhathalelo lweenwele, iBanga leCosmetic Inqanaba le-HPMC lisetyenziswa njengefilimu yangaphambili, yenza umaleko okhuselayo ojikeleze i-shaft yeenwele, ukuthintela ilahleko yokufuma kunye nokongeza ukukhanya. Ikwasetyenziswa njenge-arhente yokuthambisa kwiishampu kunye neemoviers, ukuphucula ukuthungwa kwayo kunye nokuphucula ukusebenza kwayo.
Kwishishini lokuthintela ishishini, i-HPMC ye-HEMMC ye-HPMC isetyenziswa njenge-thickener kunye nokuzinzisa kwizicoci ezingamanzi kunye nezithombe zebala. Inceda ukugcina i-viscosity yemveliso kwaye ibathintele ekubeni bahlukane. I-HPMC iyakwandisa ukususwa kwezithako ezisebenzayo kwimveliso, eyenza isebenze ngakumbi.
Kumzi-mveliso wokhathalelo lobuqu, i-HPMC ye-HEMMC ye-HPMC ye-HPMC isetyenziswa njengearhente yokumisa kwiimveliso zononophelo ngomlomo ezinjengeenyosi kunye nomlomo. Kuyanceda ukugcina izithako ezisebenzayo ezinqunyanyisiweyo kwimveliso, ukuqinisekisa ngokusasazwa. I-HPMC ikwandisa ukwenziwa kweemveliso, kubenza bakhululeke ukuba basebenzise.
Ngokubanzi, i-HPMC yenqanaba lemichiza yemihla ngemihla yindawo eqhelekileyo kwaye ibalulekile kumashishini ahlukeneyo. Ipropathi yayo eyahlukileyo, njengokugcinwa kwamanzi aphezulu, ukuphuculwa komthendeleko okhethekileyo kunye nokwenza ububi befilimu, kuyenza ibe yeyona nto ilungele ukusetyenziswa kwezicelo ezininzi. I-biodegradiation kunye nezokhuseleko ikwasenza ukuba kukhanye kwabavelisi abavelisi bekhangela ukudala iimveliso ezinobuhlobo nendalo.
Kwisishwankathelo, iBanga le-COSTEMC ye-HPMC yindawo ebalulekileyo esebenzisa iipropathi ezininzi eziluncedo. Isetyenziswe ngokubanzi kwizinto zokuthambisa, iingcingo, iimveliso zononophelo lobuqu kunye namanye amashishini. Ukusetyenziswa gwenxa kunye nokhuseleko kuyenza ilungele abavelisi bejonge ukudala iimveliso ezisebenzayo kunye nezendalo.
