Cosmetic grade hydroxypropyl methylcellulose (HPMC) ndi gulu losunthika lomwe limagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikiza zodzoladzola, zotsukira ndi zinthu zosamalira anthu. Ndiwopanda ionic cellulose ether wopangidwa ndi kusinthidwa kwa mankhwala a cellulose achilengedwe. HPMC ndi yochokera ku methylcellulose (MC) yomwe ili ndi magulu ogwira ntchito a hydroxypropyl omwe amawapatsa zinthu zapadera monga kusungirako madzi ambiri, kumamatira bwino, komanso luso lopanga filimu.
Cosmetic-grade HPMC ndi polima wa kalasi yazakudya yomwe imatha kuwonongeka komanso yotetezeka kuti igwiritsidwe ntchito pazinthu zosiyanasiyana, kuphatikiza monga zolimbitsa thupi, zolimbitsa thupi, zoyimitsa, zopangira ma emulsifiers ndi zomangira. Imasungunuka mosavuta m'madzi, ndipo kukhuthala kwake kumatha kusinthidwa posintha momwe amasinthira (DS) ndi kulemera kwake kwa polima.
M'makampani odzola zodzoladzola, tsiku lililonse kalasi yamankhwala ya HPMC imagwiritsidwa ntchito ngati thickener ndi binder muzinthu zosamalira khungu monga zonona, mafuta odzola, ndi ma gels. Zimathandizira kupanga mawonekedwe osalala, osapaka mafuta komanso kumawonjezera mphamvu zonyowa za mankhwalawa. HPMC komanso bwino kufalikira kwa mankhwala, kuwapangitsa kukhala kosavuta kufalitsa pakhungu.
Muzinthu zosamalira tsitsi, kalasi yodzikongoletsera ya HPMC imagwiritsidwa ntchito ngati filimu yakale, kupanga wosanjikiza woteteza kuzungulira tsitsi, kuteteza kutayika kwa chinyezi ndikuwonjezera kuwala. Amagwiritsidwanso ntchito ngati thickening mu ma shampoos ndi zowongolera, kukonza mawonekedwe ake ndikuwonjezera magwiridwe ake.
M'makampani otsukira, kalasi yamankhwala yatsiku ndi tsiku HPMC imagwiritsidwa ntchito ngati thickener ndi stabilizer mu zotsukira madzi ndi zofewetsa nsalu. Imathandiza kusunga mamasukidwe akayendedwe a zinthu ndi kuwaletsa kulekana. HPMC komanso timapitiriza kusungunuka kwa zosakaniza yogwira mu mankhwala, kupanga kwambiri.
M'makampani osamalira anthu, kalasi yamankhwala yatsiku ndi tsiku HPMC imagwiritsidwa ntchito ngati choyimitsa pamankhwala osamalira pakamwa monga mankhwala otsukira mkamwa ndi otsukira pakamwa. Zimathandizira kuti zosakaniza zogwira ntchito ziziimitsidwa muzogulitsa, kuwonetsetsa kugawa. HPMC imapangitsanso kapangidwe kazinthu, kuzipangitsa kukhala zomasuka kugwiritsa ntchito.
Ponseponse, kalasi yamankhwala yatsiku ndi tsiku HPMC ndiyofala komanso yofunikira m'mafakitale osiyanasiyana. Makhalidwe ake apadera, monga kusungirako madzi ambiri, kumamatira bwino komanso luso lopanga mafilimu, limapangitsa kuti likhale loyenera pazinthu zambiri. Kuwonongeka kwake komanso chitetezo chake kumapangitsanso kukhala chisankho chodziwika bwino kwa opanga omwe akufuna kupanga zinthu zoteteza zachilengedwe komanso zotetezeka.
Mwachidule, zodzikongoletsera kalasi HPMC ndi zofunika pawiri ndi katundu zambiri zothandiza. Amagwiritsidwa ntchito kwambiri muzodzoladzola, zotsukira, zinthu zosamalira anthu ndi mafakitale ena. Kusinthasintha kwake komanso chitetezo kumapangitsa kuti ikhale yabwino kwa opanga omwe akufuna kupanga zinthu zogwira mtima komanso zoteteza chilengedwe.
