I-HPMC (i-Hydroxypropyl Methyl Cellulose) yinto eqhelekileyo yepolymer ikhompawundi esetyenziswa ngokubanzi kwiimveliso zokhathalelo lomntu. Ngenxa yeempawu zayo ezikhethekileyo zomzimba kunye neekhemikhali, ezifana nokunyibilika kakuhle kwamanzi, ukulawulwa kwe-viscosity, ukubunjwa kwefilimu ecacileyo, ukuthambisa kunye nokuzinza, kunokusetyenziswa okuninzi okubalulekileyo kwinkalo yokunyamekela komntu.
1. I-Thickener kunye ne-stabilizer
Njenge-thickener esebenzayo kunye nokuzinzisa, i-HPMC isetyenziswa kakhulu kwiimveliso zokhathalelo lwesikhumba, ishampu, ijeli yeshawa kunye nezinye iimveliso. Iyakwazi ukunyibilika emanzini ukwenza isisombululo se-viscous, inike imveliso i-viscosity efanelekileyo, iyenze ibe yinkimbinkimbi kwaye izinzile ngexesha lokusetyenziswa.
Ngokomzekelo, kwi-creams okanye i-lotions, i-HPMC inokwenza imveliso ibe yinto efanayo kwaye ithintele i-stratification ngokulungelelanisa i-viscosity yesisombululo. Olu phawu lufanelekile ngokukhethekileyo kwiinkqubo ze-multiphase (ezifana ne-oyile-in-water okanye i-emulsions yamanzi kwi-oyile), inceda ukwenza inkqubo ye-emulsified ezinzileyo yokuthintela ukuhlukana kwezithako kunye nokuwohloka kwemveliso. Ukongezelela, inokuzinzisa ezinye izithako ezisebenzayo, ezifana ne-vitamin C, i-retinol, njl., ukwenzela ukuba ukusebenza kwezi zithako kwifomula kugcinwe.
2. Abayili befilimu
I-HPMC inamandla okwenza ifilim kwaye ihlala isetyenziswa njengefilimu yangaphambili kwiimveliso zokhathalelo lomntu. Umzekelo, kwiimveliso zokhathalelo lweenwele, i-HPMC inokwenza ifilimu ekhuselayo kumphezulu weenwele ukuvala ukufuma nokukhusela iinwele. Le filimu ayigcini nje ukuthintela ukulahleka komswakama kwizinwele, kodwa inika ukukhanya kunye nokuguquguquka kweenwele, ngaloo ndlela iphucula ukuthungwa kweenwele emva kokusetyenziswa.
Ukongeza, i-HPMC isetyenziswa ngokubanzi kwiimaski zobuso, izithambiso kunye ne-sunscreens. Emva kokuqulunqwa kwefilimu, i-HPMC inokwenza ifilimu ephefumulayo, enokuthi itshixe ngokufanelekileyo izithako ezisebenzayo kwimveliso ukuthintela ukulahlekelwa okanye ukuguquguquka, kwaye kwangaxeshanye ayiyi kwenza ulusu lube lukhuni okanye lunamathele, ngaloo ndlela luphucula amava omsebenzisi.
3. Izinto zokuthambisa
I-HPMC nayo ineempawu ezilungileyo zokuthambisa kwiimveliso zokhathalelo lomntu. Inokunceda ulusu lugcine ibhalansi yokufuma ngokufunxa ukufuma emoyeni, ngaloo ndlela iphucula isiphumo sokuthambisa seemveliso zokhathalelo lwesikhumba. Le propati yenza i-HPMC ibe yinxalenye ebalulekileyo yeemveliso ezininzi zokuthambisa, ezilungele ukusetyenziswa kwiimveliso zokunakekelwa kwesikhumba esomileyo.
Kwezinye izitshizi zokuthambisa okanye iitoni, i-HPMC ayinakunceda kuphela ukutshixa ukufuma, kodwa inika imveliso i-silkier touch kunye nokuphucula intuthuzelo xa isetyenziswa.
4. Isithambiso
I-HPMC ingasetyenziswa njenge-lubricant ukunika amava agudileyo kwiimveliso zokhathalelo lobuqu. Kwiimveliso ezifana nokucheba iikhrimu kunye neejeli, i-HPMC inceda ukunciphisa ukukhuhlana, ukunciphisa ukucaphuka kwesikhumba, kunye nokubonelela ngamava okutsheva athambileyo. Ukongeza, kwezinye iindawo zokunakekelwa kwesikhumba okanye i-essces, inokubonelela ngokubamba okugudileyo kunye nobuthathaka kunye nokuphucula induduzo yonke yemveliso.
5. Umlawuli we-Foam
I-HPMC ingasetyenziswa njengomlawuli we-foam ukulawula ugwebu lwemveliso. Kwizinto zokucoca ubuso kunye neegels zeshawa, isixa esifanelekileyo se-HPMC sinokunceda imveliso ibe negwebu elithambileyo nelizinzileyo, ukuphucula umphumo wokucoca kunye namava omsebenzisi. Ngexesha elifanayo, likwanceda ukukhusela ukubunjwa kwe-foam ngokugqithiseleyo, ngaloo ndlela kuphuculwe ukusebenza kakuhle kokucoca kwemveliso kunye nokunciphisa inkunkuma yamanzi ngexesha lokuhlanjululwa.
6. Ukhuseleko kunye nobulali
I-HPMC ithathwa njengento ekhuselekileyo nesezantsi-ucaphuka, nto leyo eyenza ukuba isetyenziswe ngokubanzi kwiimveliso zokhathalelo lwesikhumba kunye neemveliso zononophelo lwabantwana. Xa kuthelekiswa nezinye iikhemikhali ezicaphukisa kakhulu, i-HPMC iphantsi kakhulu ekucaphukiseni ulusu kwaye ayithandeki kwizinto ezibangelwa yi-allergies. Ke ngoko, ihlala isetyenziswa kwiimveliso zokhathalelo lwemihla ngemihla ezifana nezicoci zobuso kunye neloshini ukunceda ukudala imvakalelo ethambileyo yokusetyenziswa.
Ngenxa yobume be-non-ionic ye-HPMC, ikwahambelana kakhulu nezinye izithako zemichiza kwaye ingasetyenziswa ngeentlobo zezithako ezisebenzayo ngaphandle kokuvelisa ukusabela kweekhemikhali ezimbi. Oku kubaluleke kakhulu kwiifomyula eziyinkimbinkimbi zokuqinisekisa ukuzinza kunye nokubambisana phakathi kwezithako ezahlukeneyo.
7. Ukulibazisa ukukhutshwa kweemveliso
Kwezinye iimveliso zokunakekelwa okukhethekileyo, ezifana ne-anti-aging creams, i-cosmeceuticals okanye i-essence essences, i-HPMC inokulibazisa ukukhutshwa kwezithako ezisebenzayo ngokwenza ifilimu ekhuselayo, ngaloo ndlela yenza umphumo wokunakekelwa kwesikhumba uhlale ixesha elide. Olu phawu lokukhululwa olulibazisiweyo alukwazi nje ukuphucula umphumo wokusetyenziswa kwemveliso, kodwa nokunciphisa ukucaphuka okunokwenzeka kwezinto ezisebenzayo kwesikhumba, ngaloo ndlela kuphuculwe amava omsebenzisi.
8. Umsebenzi we-Antioxidant kunye ne-shelf-stable
Ngenxa yokuba i-HPMC inokwenza ifilimu ekhuselayo, ngakumbi kwiimveliso zokhathalelo lomntu, inokudlala indima ethile ye-antioxidant kwaye ilibazise ukubola kwezithako ezithile ezixutywe lula kwimveliso. Oku kuvumela iimveliso zokhathalelo lobuqu eziqulathe i-HPMC ukuba zibe nobomi obude kwaye zigcine ukusebenza kwazo ngexesha lokusetyenziswa.
9. Njenge-arhente exhomayo kunye ne-arhente yokusasaza
I-HPMC ingasetyenziswa njenge-arhente yokuxhoma kunye ne-arhente yokusabalalisa ukukhusela amasuntswana aqinileyo ekuzinzeni kwiimveliso zolwelo. Ngokomzekelo, kwezinye iindawo ezihlambulukileyo okanye i-body scrubs equkethe i-scrub particles, i-HPMC inokusabalalisa ngokulinganayo ezi ngqungquthela ukuphepha ingxaki yokuqokelela okanye imvula ngexesha lokusetyenziswa. Esi siphumo sokunqunyanyiswa senza imveliso ibe yinto efanayo kwaye iqinisekisa iziphumo ezihambelanayo rhoqo xa isetyenziswa.
10. Ukusetyenziswa kwezithambiso
I-HPMC isetyenziswa ngokuqhelekileyo kwiimveliso zokuthambisa, ezifana nesiseko, i-lipstick kunye ne-mascara. Njengefilimu yangaphambili, inokunceda izithambiso ukuba zibambelele ngcono kumphezulu wolusu okanye weenwele kwaye zandise ukuqina kwe-makeup. Kwi-mascara, i-HPMC inokonyusa i-curl kunye nobukhulu bee-eyelashes, ngelixa isiseko, inceda ukusasaza ii-pigments ngokulinganayo ukwenza i-makeup ibe yendalo.
Njengesixhobo esinemisebenzi emininzi ekrwada, i-HPMC isetyenziswa ngokubanzi kwiimveliso zokhathalelo lomntu ngenxa yendlela egqwesileyo yokwenza ifilimu, ukuqina kunye neempawu zokuthambisa. I-HPMC idlala indima ebalulekileyo kuyo yonke into ukusuka kukhathalelo olusisiseko lolusu kunye neemveliso zokhathalelo lweenwele ukuya kwizinto zokuthambisa ezikumgangatho ophezulu kunye nezithambiso. Njengoko imfuno yabathengi yobulali kunye nokusebenza kakuhle kweemveliso kuqhubeka nokukhula, umda wesicelo se-HPMC kulindeleke ukuba wande ngakumbi. Ayinakuphucula kuphela ukuvakalelwa kwemveliso, kodwa iphucula uzinzo kunye nokhuseleko lwefomula, ukuzisa izinto ezintsha kunye namathuba ophuhliso kwiimveliso zokhathalelo lomntu.
