Hydroxypropylmethylcellulose (HPMC) ni polymer ikomoka kuri selile ikoreshwa cyane mu nganda zitandukanye, harimo ubwubatsi, imiti n’inganda za buri munsi. Nibintu byinshi bikora nibintu byihariye bitanga inyungu nyinshi mubicuruzwa bitandukanye. Mu moko menshi ya HPMC, amazi akonje ako kanya icyiciro ni kimwe mubigaragara cyane cyane mubijyanye nimiti ya buri munsi.
(1), ibisobanuro n'inzira yo kubyara
Mbere yo gusobanukirwa ibiranga imiti ya buri munsi ya chimique amazi akonje ako kanya HPMC, reka tubanze dusobanure ibisobanuro byayo nibikorwa. HPMC ni ether ya selile idafite ionic, iboneka mugutunganya selile naturel (nka pamba ya pamba cyangwa pompe yimbaho) hamwe na alkali, hanyuma ikayitera hamwe na okiside ya propylene na methyl chloride. Iyi miti yimiti itanga ifu yera kugeza yera yera iboneka mumazi no mumashanyarazi. Amazi akonje ako kanya urwego rwa HPMC bivuga ubwoko bwihariye bwa HPMC bworoshye gushonga mumazi akonje, bitandukanye na HPMC isanzwe isaba amazi ashyushye gushonga. Ihinduka ryamazi akonje ako kanya kugerwaho muguhitamo ibikoresho fatizo, guhindura imiterere ya etherification, no kugenzura ingano yubunini.
(2). Ibiranga ibyiza
Amavuta yo kwisiga yo mu bwoko bwa cosmetic ako kanya HPMC ifite ibintu byinshi nibyiza bituma iba ingirakamaro mubintu byinshi byita kumuntu. Dore bimwe mubiranga ibintu byingenzi:
1. Ubushobozi bwo gufata amazi menshi: HPMC ni hydrophilique, bivuze ko ikurura kandi ikagumana amazi. Imiti ya chimique ya buri munsi amazi akonje ako kanya HPMC ifite ubushobozi bwo gufata amazi menshi, bikaba byiza kongera ubwiza nubwiza bwibicuruzwa. Uyu mutungo ni ingirakamaro cyane muguhanagura neza, shampoo nibicuruzwa byoza umubiri.
2. Imiterere yo gukora firime: HPMC ikora firime ibonerana kandi yoroheje iyo yumye kuruhu cyangwa umusatsi. Iyi firime irinda uruhu ibintu byo hanze nko guhumana, imirasire ya UV hamwe nimiti. Bituma kandi umusatsi ugaragara neza kandi neza. Mubicuruzwa bya chimique bya buri munsi, imiterere ya firime ya HPMC ikoreshwa kenshi mubicuruzwa bitunganya imisatsi, amavuta yo kwisiga izuba, amavuta meza, nibindi.
3. Kubyimba no kwigana: HPMC irashobora kubyimba no gusohora amata, bivuze ko ishobora gufasha guhagarika amavuta namazi mubicuruzwa. Iyi mikorere ni ingirakamaro cyane mubicuruzwa byo mu bwoko bwa cream nka amavuta yo kwisiga, amavuta yo kwisiga hamwe na cream y'amaso.
4. Yoroheje kandi idatera uburakari: HPMC ni biocompatible, idafite uburozi butazatera uburakari cyangwa allergie. Nibyoroshye kuruhu bitabangamiye pH karemano cyangwa lipide. Uyu mutungo ukora ikintu cyiza mubicuruzwa byita kubana, masike yo mumaso nibicuruzwa byuruhu rworoshye.
5. Guhindagurika: HPMC irashobora gukoreshwa hamwe nibindi bikoresho, nka surfactants, preservatives, impumuro nziza, nibindi, bitagize ingaruka kumikorere yabyo. Irashobora guhuzwa nuburyo butandukanye kugirango itange amazi, ituje, isuku nibindi byiza.
(3). Umwanya wo gusaba
Imiti ya chimique ya buri munsi amazi akonje ako kanya HPMC ifite uburyo bwinshi bwo gukoresha mubikorwa byita kubantu. Bimwe mubicuruzwa bikunze gukoreshwa ni:
1. Guhanagura neza: HPMC irashobora gutanga umubyimba, kubika amazi hamwe nibintu byangiza uruhu bisabwa no guhanagura. Irashobora gutuma ibihanagura byunvikana cyane, byoroshye kandi biramba.
2. Shampoo na gel gel yo kwiyuhagira: HPMC irashobora kongera ubukonje no kubira ifuro ya shampoo na gel yogesha, bikaborohera kuyikoresha no kwoza. Ifite kandi ingaruka kumisatsi no kuruhu.
3. Ibicuruzwa bitunganya imisatsi: HPMC ikora firime yoroheje ikikije umusatsi, ifasha kugumana imiterere nubunini. Irinda kandi umusatsi ubushuhe nubushuhe.
4. Amavuta yo kwisiga yizuba: HPMC irashobora gukora nkizuba ryizuba kugirango ryongere imikorere ya UV. Itanga kandi silike kandi idafite amavuta kuruhu.
5. Mask: HPMC irashobora gutanga gel, ibimera neza hamwe nogukora firime bisabwa na mask. Ifasha mask kwizirika ku ruhu no gutanga ibintu bifatika.
(4). mu gusoza
Amavuta yo kwisiga yo mumazi akonje hydroxypropyl methylcellulose nibintu byinshi byunguka byongera ubwiza nibikorwa byimikorere yibicuruzwa byawe bwite. Ubushobozi bwayo bwo gufata amazi menshi, imiterere ya firime, kubyimba no kwigana emulisitiya, ubwitonzi nuburyo bwinshi bituma iba ikintu cyingenzi muburyo bwinshi. Ikoreshwa ryinshi mu guhanagura neza, shampo no koza umubiri, ibicuruzwa byogosha umusatsi, amavuta yo kwisiga izuba, hamwe na masike yo mumaso byerekana uburyo bwinshi, akamaro, ningirakamaro. Nkuko abaguzi bafite ibyo basabwa kugirango bakore neza, umutekano hamwe nigihe kirekire cyibicuruzwa byita ku muntu ku giti cye, amazi akonje yo mu rwego rwa buri munsi ako kanya HPMC irashobora kugira uruhare runini mu nganda.
