HPMC Hypromellose

Hydroxypropyl methylcellulose(HPMC), ndi mankhwala osiyanasiyana omwe ali ndi chilinganizo [C6H7O2(OH)3-mn(OCH3)m(OCH2CH(OH)CH3)n]x, pamene m imayimira digiri ya methoxy substitution ndipo n imayimira digiri ya hydroxypropoxy. m'malo. Amachokera ku cellulose, polima wachilengedwe wopangidwa kuchokera kumakoma a cell a zomera. HPMC ndi yopanda fungo, yopanda kukoma, komanso yopanda poizoni. Ili ndi zinthu zosiyanasiyana zakuthupi monga kusungunuka m'madzi, kutentha kwa gelation, komanso kuthekera kopanga mafilimu, ndikupangitsa kuti azigwiritsidwa ntchito kwambiri m'mafakitale angapo.

M'makampani opanga mankhwala, HPMC imagwiritsidwa ntchito kwambiri ngati chothandizira-chinthu chopangidwa pamodzi ndi mankhwala omwe amagwiritsidwa ntchito ndi mankhwala, pofuna kukhazikika kwa nthawi yaitali, kukulitsa mapangidwe olimba omwe ali ndi zosakaniza zogwira ntchito pang'onopang'ono (zomwe nthawi zambiri zimatchulidwa monga chodzaza, chosungunula, kapena chonyamulira), kapena kupititsa patsogolo kuyamwa kapena kusungunuka. Makapisozi a HPMC ndi m'malo mwa makapisozi a gelatin kwa omwe sadya masamba ndipo amagwiritsidwa ntchito popanga zowongolera, zomwe zimapangitsa kuti mankhwalawa atulutsidwe pang'onopang'ono pakapita nthawi. Mayankho a HPMC amathanso kukhala ngati viscolyzers kuti awonjezere kukhuthala kwa mayankho a ophthalmic, kuwongolera kutsata kwazachilengedwe, komanso kutalikitsa nthawi yokhazikika ya mankhwala pakhungu.

M'makampani azakudya, HPMC imadziwika ngati chowonjezera chazakudya (E464) ndipo imagwira ntchito zingapo monga emulsifier, thickening agent, ndi stabilizer. Amagwiritsidwa ntchito popanga zakudya zosiyanasiyana kuti asinthe mawonekedwe, kusunga chinyezi, ndikupanga mafilimu odyedwa. Thermal gelation katundu wa HPMC ndi wofunika kwambiri pa ntchito zomwe zimafuna gelling pa kutentha kwina, monga maphikidwe a zamasamba ndi vegan komwe angalowe m'malo mwa gelatin. HPMC imathandiziranso ku moyo wa alumali ndi mtundu wa zinthu zowotcha, ma sosi, ndi zokometsera polamulira crystallization ndi chinyezi.

Makampani omanga amapindula ndi HPMC popanga zida zomangira. Ntchito zake zimaphatikizapo kugwira ntchito ngati chomangira ndi kusunga madzi mumatope, pulasitala, ndi zokutira, kukonza magwiridwe antchito, kuchepetsa kugwiritsa ntchito madzi, komanso kukulitsa nthawi yotseguka - nthawi yomwe chinthu chimakhala chogwiritsidwa ntchito. HPMC imakulitsa mawonekedwe a simenti yochokera ku simenti, kupereka kumamatira bwino, kufalikira, komanso kukana kugwa.

M'makampani opanga zodzoladzola ndi chisamaliro chamunthu, HPMC imagwira ntchito ngati wopanga mafilimu, emulsifier, ndi rheology modifier muzinthu monga mafuta odzola, mafuta opaka, ndi ma gels atsitsi. Kugwirizana kwake ndi mitundu yosiyanasiyana ya khungu komanso kuthekera kokhazikika kwa emulsions kumawonjezera magwiridwe antchito komanso moyo wautali. HPMC a hydration katundu kupanga kukhala zofunika pophika inskin chisamaliro mankhwala, kuthandiza kusunga chinyezi ndi kupereka kumverera yosalala. Mwachidule, kusinthasintha kwa HPMC kumaphatikizapo mankhwala, chakudya, zomangamanga, ndi zodzoladzola, kuwonetsa kufunikira kwake monga chogwiritsira ntchito zosiyanasiyana pa ntchito zosiyanasiyana.
