Ogwedezeka,Hpmc (hydroxypropyl methylcellulose)ndi lodziwika bwino komanso wokhazikika. Sikuti zimangokhala ndi mphamvu yabwino kwambiri, komanso imasintha madzimadzi, kuyimitsidwa ndi zokutira zotupa. Chifukwa chake, imagwiritsidwa ntchito mosiyanasiyana m'malo osiyanasiyana, oyeretsa, shampoos, ma gels osakira ndi zinthu zina. Kukhazikika kwa hpmc mu zotchinga ndikofunikira pakuchita kwa malonda, komwe kumakhudza mwachindunji kutsuka, magwiridwe antchito, kapangidwe kake ndi chidziwitso.
Udindo wa HPMC mu zotchinga
Kukula Kwakukulu: HPMC, ngati ThiCCner, imatha kusintha mafayilo a chotupacho, kuti cholefukira chikhoza kuphatikizidwa pansi pomwe chikugwiritsidwa ntchito, kukonza kusamba. Nthawi yomweyo, kukhazikika kwabwino kumathandizira kuwongolera madzi otsekemera, ndikupangitsa kuti isakhale yopyapyala kapena kuwonekera kwambiri, komwe kumakhala kovuta kwa ogula kuti azigwiritsa ntchito.
Kukhazikika: HPMC imatha kukonza kukhazikika kwa chotchinga ndikuletsa stratization kapena mpweya wazosakaniza mu formula. Makamaka m'madzi ena otetezedwa ndi oyera, hpmc imatha kupewa kusakhazikika kwa mankhwalawa panthawi yosungirako.
Sinthani katundu wa foamtete: thovu ndi gawo lofunikira la zinthu zambiri zoyeretsa. Kuchuluka kwa hpmc kungapangitse zotsekemera kumabala chithovu chokhazikika komanso chokhalitsa, potero kumawonjezera ntchito yoyeretsa ndi othandizira.
Sinthani mphamvu yazachinyengo: Helinence®hpmc ili ndi zinthu zabwino zamitundu ndipo zimatha kusintha mamasukidwe ndi mafuta am'matumbo, kupanga malonda mosavuta akagwiritsidwa ntchito ndikupewa kukhala wochepa thupi kapena wandiweyani.
Kukhazikika kwa HPMC
Kukhazikika kwa hpmc ku zotsekemera kumafunikira kusinthidwa malinga ndi mtundu ndi cholinga chogwiritsa ntchito. Nthawi zambiri, kuchuluka kwa HPMC ku zotsekemera nthawi zambiri kumakhala pakati pa 0,2% ndi 5%. Kuchita zinthu mwachindunji kumadalira zinthu zotsatirazi:
Mtundu wopatukana: mitundu yosiyanasiyana ya zotsekemera zimakhala ndi zofunikira zosiyanasiyana kwa HPMC. Mwachitsanzo:
Mafuta amadzimadzi: Mafuta amadzimadzi nthawi zambiri amagwiritsa ntchito kutsika kwa HPMC, makamaka 0,2% mpaka 1%. Kuchuluka kwambiri kwa HPMC kungapangitse kuti chinthucho chikhale chowoneka bwino kwambiri, chikukhudza thanzi ndi madzi ogwiritsa ntchito.
Zokhumudwitsa kwambiri: zotsekemera kwambiri zimatha kufuna kuchuluka kwa hpmc, nthawi zambiri 1% mpaka 3%, zomwe zingathandize kuwonjezera mamasukidwe ake komanso kupewa mpweya wotsika.
Zingwe zowonongeka: za zotchinga zomwe zimafunikira kupanga chithovu chowonjezereka, ndikuwonjezera kuchuluka kwa HPMC moyenera, nthawi zambiri pakati pa 0,5% ndi 2%, zitha kuthandiza kukulitsa kukhazikika kwa chithovu.
Zofunikira Zakukulu: Ngati chotchinga chimafunikira ma visction apamwamba kwambiri (monga shalm nthose yoyeretsa), kuchuluka kwa HPMC kungafunikire, nthawi zambiri pakati pa 2% ndi 5%. Ngakhale kuti kukhazikika kwambiri kumatha kuwonjezera mafakitiwo, zingayambitsenso kufalitsa zina mwazinthu mu formula ndikukhudza kukhazikika konse, kotero kusintha koyenera kumafunikira.
PH ndi kutentha kwa formula: zotsatira za kukula kwa hpmc zimakhudzana ndi PH ndi kutentha. HPMC imachita bwino kusala nawo zinthu zofooka za alkaliner, ndipo malo achitetezo kapena alkalining angakhudze luso lake. Kuphatikiza apo, kutentha kwambiri kumatha kukulitsa kusungunuka kwa HPMC, momwe zimafunikira kusinthidwa m'njira zambiri kutentha kwambiri.
Kugwirizana ndi zosakaniza zina: Evancence®hpmc amatha kulumikizana ndi zosakaniza zina, monga okonda, pomwe anyezi, ndi anyezi, ndi anyezi . Chifukwa chake, popanga formula, kuyanjana kumeneku kumayenera kulingaliridwa ndipo kukhazikika kwa HPMC kuyenera kusinthidwa.
Zotsatira zakugwiririra pachabe
Mukamasankha ndende ya HPMC, kuwonjezera pakuganizira za kukula, kutsuka kwenikweni kwa chotsekemera kuyenera kugwiritsidwa ntchito. Mwachitsanzo, kwambiri kukhazikika kwa hpmc kungakhudze zotchinga ndi zotchinga za chitsitsi, zomwe zimapangitsa kuchepa kwa mphamvu yotsuka. Chifukwa chake, kukhazikika kokwanira sikuyenera kungotsimikizira kusasinthasintha koyenera komanso madzi ambiri, komanso kuwonetsetsa kuti zinthu zikuyeretse bwino.
Mlandu weniweni
Kugwiritsa ntchito shampoo: kwa shampoo wamba, kukhazikika kwa kudandaula kufika pakati pa 0,5% ndi 2%. Kukwera kwambiri kukhazikika kumapangitsa shampoo kukhala ma visaus, akukhudza kuthira ndikugwiritsa ntchito, ndipo kungakhudze mapangidwe ndi kukhazikika kwa thovu. Zogulitsa zomwe zimafuna ma visction apamwamba (monga kutsuka kwa shampoo kapena shampu yokhazikika), kuchuluka kwa HPMC kungakhale kowonjezereka mpaka 2% mpaka 3%.
Zoyeretsa zambiri: zoyeretsa zina pabanja, kuchuluka kwa HPMC kumatha kulamuliridwa pakati pa 0,3% ndi 1%, komwe kungawonetsetse kuyeretsa komwe kumapangitsa kuti kusasinthasintha kwamadzimadzi.
Monga Thicker, kupsinjika kwaHpmcKugwedezeka kumayenera kuganizira zinthu ngati mtundu wazogulitsa, zofunikira, njira zosafunikira ndi zomwe wagwiritsa ntchito. Kukhazikika kokulirapo nthawi zambiri pakati pa 0,2% ndi 5%, ndipo kukhazikika kwake kuyenera kusinthidwa malinga ndi zosowa zenizeni. Pofuna kukwaniritsa kugwiritsa ntchito HPMC, kukhazikika, madzimadzi ndi ziwiya za zotsekemera zimatha kusintha popanda kusokoneza magwiridwe antchito, kukumana ndi zosowa za ogula osiyanasiyana.
