Hydroxypropylmethylcellulose (HPMC) ndi polima yopangidwa ndi cellulose yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza mafakitale omanga, opanga mankhwala ndi tsiku lililonse.Ndizinthu zambiri zomwe zimakhala ndi katundu wapadera zomwe zimapereka ubwino wambiri pazinthu zosiyanasiyana.Pakati pa mitundu yambiri ya HPMC, kalasi yamadzi ozizira nthawi yomweyo ndi imodzi mwazofunikira kwambiri, makamaka pankhani yamankhwala atsiku ndi tsiku.
(1), kutanthauzira ndi kupanga
Musanamvetsetse mawonekedwe a tsiku ndi tsiku amadzi ozizira a HPMC, tiyeni timvetsetse tanthauzo lake ndi kupanga kwake.HPMC ndi non-ionic mapadi efa, amene analandira pochiza masoka mapadi (monga linters thonje kapena nkhuni zamkati) ndi zamchere, ndiyeno etherifying ndi propylene okusayidi ndi methyl kolorayidi.Mankhwalawa amatulutsa ufa woyera mpaka woyera womwe umasungunuka m'madzi ndi zosungunulira organic.Madzi ozizira nthawi yomweyo kalasi ya HPMC amatanthauza mtundu wina wa HPMC womwe ndi wosavuta kusungunuka m'madzi ozizira, mosiyana ndi HPMC wamba yomwe imafuna madzi otentha kuti asungunuke.Izi madzi ozizira nthawi kusintha zimatheka ndi kusankha zipangizo, kusintha zinthu etherification, ndi kulamulira tinthu kukula kugawa.
(2).Mbali ndi ubwino
Zodzikongoletsera kalasi yamadzi ozizira nthawi yomweyo HPMC ili ndi katundu ndi maubwino angapo omwe amapangitsa kuti ikhale yofunikira pazinthu zambiri zosamalira anthu.Nazi zina mwazinthu zake zodziwika bwino:
1. Kuchuluka kwa madzi osungira madzi: HPMC ndi hydrophilic, kutanthauza kuti imakopa ndikusunga madzi.Daily mankhwala kalasi madzi ozizira pompopompo HPMC ali mkulu mphamvu posungira madzi, amene n'kopindulitsa kuonjezera mamasukidwe akayendedwe ndi bata la mankhwala.Katunduyu ndiwothandiza makamaka pazopukuta zonyowa, shampu ndi zotsukira thupi.
2. Mafilimu opanga mafilimu: HPMC imapanga filimu yowonekera komanso yosinthika ikauma pakhungu kapena tsitsi.Filimuyi imateteza khungu ku zinthu zakunja monga kuipitsa, kuwala kwa UV ndi mankhwala.Zimapangitsanso tsitsi kukhala lowala komanso losalala.Pazamankhwala atsiku ndi tsiku, zinthu zopanga filimu za HPMC nthawi zambiri zimagwiritsidwa ntchito pazokongoletsa tsitsi, mafuta opaka sunscreen, moisturizer, etc.
3. Makulidwe ndi emulsifying katundu: HPMC akhoza thicken ndi emulsify mafomu, kutanthauza kuti zingathandize bata mafuta ndi madzi mankhwala.Izi ndizothandiza makamaka pazinthu zamtundu wa kirimu monga mafuta odzola, zonona za nkhope ndi zonona zamaso.
4. Ofatsa komanso osakwiyitsa: HPMC ndi biocompatible, non-poizoni popanga zomwe sizidzayambitsa kupsa mtima kapena ziwengo.Ndiwofatsa pakhungu popanda kusokoneza pH yachilengedwe kapena chotchinga cha lipid.Katunduyu amapangitsa kuti ikhale yopangira zinthu zosamalira ana, masks amaso ndi mankhwala akhungu.
5. Kusinthasintha: HPMC ikhoza kugwiritsidwa ntchito limodzi ndi zinthu zina, monga zowonjezera, zotetezera, zonunkhira, ndi zina zotero, popanda kusokoneza ntchito yake.Ikhoza kusinthidwa kuti ikhale yosiyana siyana kuti ipereke moisturizing, kutonthoza, kuyeretsa ndi zina zabwino.
(3).Malo ogwiritsira ntchito
Daily mankhwala kalasi madzi ozizira pompopompo HPMC ali osiyanasiyana ntchito makampani chisamaliro munthu.Zina mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi izi:
1. Zopukuta zonyowa: HPMC ikhoza kupereka kukhuthala, kusunga madzi ndi zinthu zokometsera khungu zomwe zimafunidwa ndi zopukuta zonyowa.Zingapangitse zopukuta kukhala zonyowa, zofewa komanso zolimba.
2. Shampoo ndi gel osamba: HPMC imatha kuwonjezera kukhuthala ndi kutuluka thovu kwa shampu ndi gel osamba, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito ndikutsuka.Zimakhalanso ndi zotsatira zowonongeka pa tsitsi ndi khungu.
3. Zopangira tsitsi: HPMC imapanga filimu yosinthika kuzungulira tsitsi, kuthandiza kusunga mawonekedwe ake ndi kuchuluka kwake.Zimatetezanso tsitsi ku chinyezi ndi kuwonongeka kwa kutentha.
4. Mafuta odzola oteteza ku dzuwa: HPMC imatha kukhala ngati chowonjezera choteteza ku dzuwa kuti chiwonjezeke bwino pakusefa kwa UV.Zimaperekanso silika komanso yopanda mafuta pakhungu.
5. Mask: HPMC ikhoza kupereka gel, moisturizing ndi kupanga mafilimu zomwe zimafunidwa ndi chigoba.Zimathandizira mask kumamatira pakhungu ndikupereka zopangira zogwira ntchito.
(4).Pomaliza
Cosmetic grade madzi ozizira instant hydroxypropyl methylcellulose ndi zinthu zambiri zothandiza zomwe zimapangitsa kuti zinthu zisamayende bwino.Kuchuluka kwa madzi osungira madzi, kupanga mafilimu, kukhuthala ndi emulsifying katundu, kufatsa ndi kusinthasintha zimapangitsa kuti zikhale zofunikira kwambiri muzopanga zambiri.Kugwiritsiridwa ntchito kwake kofala mu zopukutira zonyowa, ma shampoos ndi zochapira thupi, zopangira tsitsi, mafuta opaka mafuta oteteza ku dzuwa, ndi zopaka kumaso zimasonyeza kusinthasintha kwake, zothandiza, ndi zogwira mtima.Popeza ogula ali ndi zofunikira zapamwamba pakuchita bwino, chitetezo ndi kukhazikika kwa zinthu zosamalira anthu, HPMC ikuyenera kukhala ndi gawo lofunikira kwambiri pamsika.
