Hydroxyethylcellulose (HEC) ndi polima wosasungunuka m'madzi yemwe amagwiritsidwa ntchito kwambiri posamalira khungu. Monga cellulose yosinthidwa, hydroxyethylcellulose imayambitsa magulu a ethoxy mu unyolo wa cellulose wachilengedwe kuti ukhale wosungunuka komanso wokhazikika m'madzi. Ntchito zake zazikulu pakusamalira khungu zimaphatikizapo kukhuthala, kunyowetsa, kukhazikika, komanso kukonza kukhudza kwamankhwala.
1. Wonenepa
Imodzi mwa ntchito zofunika kwambiri za hydroxyethylcellulose ndi monga thickener. M'zinthu zosamalira khungu monga mafuta odzola, mafuta odzola, oyeretsa ndi ma gels, ntchito ya thickeners ndikuwonjezera kukhuthala ndi kusasinthasintha kwa mankhwala, kuti zikhale zosavuta kugwiritsa ntchito ndikusunga pakhungu, potero kupititsa patsogolo ntchito yogwiritsira ntchito mankhwalawa. Hydroxyethyl cellulose akhoza kupanga yunifolomu njira colloidal mwa kuyamwa madzi ndi kutupa, potero kuonjezera mamasukidwe akayendedwe a chilinganizo, ndipo thickening zotsatira si anakhudzidwa ndi electrolytes, kotero izo zikhoza stably alipo mu mitundu yosiyanasiyana ya mafomu.
2. Moisturizing zotsatira
Posamalira khungu, kunyowa ndi ntchito yofunika kwambiri, ndipo hydroxyethyl cellulose imathandizanso pankhaniyi. Ikhoza kuyamwa ndi kusunga madzi enaake, kupanga chotchinga chonyowa kuti chiteteze kutaya kwambiri kwa chinyezi kuchokera pakhungu. Mukagwiritsidwa ntchito limodzi ndi zokometsera zina, hydroxyethyl cellulose imatha kuthandizira kutseka chinyezi, kutalikitsa kunyowa, ndikusunga khungu lofewa komanso losalala mukatha kugwiritsa ntchito.
3. Stabilizer
Ma cellulose a Hydroxyethyl amagwiranso ntchito ngati chokhazikika kuti ateteze kutsika kwazinthu kapena kugwa kwamvula. Muzinthu zambiri zopangidwa ndi emulsified, monga mafuta odzola kapena zonona, kukhazikika pakati pa gawo lamadzi ndi gawo lamafuta ndikofunikira. Ma cellulose a Hydroxyethyl amatha kusintha kukhazikika kwa dongosolo la emulsified ndikukulitsa moyo wa alumali wa mankhwalawa powonjezera kukhuthala kwa dongosolo ndikuletsa kusungunuka kwa zinthu.
4. Sinthani katundu kukhudza
Muzinthu zosamalira khungu, kukhudza ndi gawo lofunika kwambiri pazochitika za ogula. Ma cellulose a Hydroxyethyl amatha kupatsa mankhwalawa kukhudza kopepuka komanso kosalala popanda kusiya kumverera komamatira kapena mafuta. Chifukwa chake, nthawi zambiri amagwiritsidwa ntchito pazinthu zomwe zimafuna kukhudza kotsitsimula komanso kopepuka, monga ma gels ndi mafuta otsitsimula. Kuphatikiza apo, kupsa mtima kochepa komanso kuyanjana kwapakhungu kwa hydroxyethyl cellulose kumapangitsa kuti ikhale yoyenera pazinthu zosamalira khungu.
5. Limbikitsani magwiridwe antchito azinthu
Kuphatikiza pa ntchito zomwe tazitchulazi, hydroxyethyl cellulose imathanso kupititsa patsogolo kufanana kwa kugawa kwazinthu zogwira ntchito, kuonetsetsa kuti zosakaniza zogwira ntchito zimatha kugawidwa mofanana pakhungu, potero kumapangitsa kuti mankhwalawa awonongeke. Mwachitsanzo, m'mapangidwe omwe ali ndi antioxidants, mankhwala ophera tizilombo toyambitsa matenda kapena zinthu zoyera, kugwiritsa ntchito hydroxyethyl cellulose kungathandize kuti zinthuzi zizigwira ntchito bwino.
6. Hypoallergenicity
Monga zinthu zopanda ionic polima, hydroxyethyl cellulose imakhala ndi allergenicity yochepa komanso kukwiya kochepa chifukwa cha kapangidwe kake ka mankhwala, kotero imagwiritsidwanso ntchito kwambiri pazinthu zosamalira khungu. Kwa anthu omwe amakonda kutengeka kapena kuwonongeka kwa zotchinga pakhungu, hydroxyethyl cellulose ndi chisankho chotetezeka komanso chothandiza.
7. Biodegradability
Hydroxyethyl cellulose ndi chinthu chosinthidwa chochokera ku cellulose yachilengedwe, motero imakhala ndi kuwonongeka kwachilengedwe komanso kuyanjana ndi chilengedwe. Potengera chidwi cha ogula pachitetezo cha chilengedwe komanso chitukuko chokhazikika, zinthu zomwe zimagwiritsidwa ntchito ndi hydroxyethyl cellulose zimavomerezedwa kwambiri pamsika.
8. Chilinganizo chogwirizana
Ma cellulose a Hydroxyethyl ali ndi mawonekedwe abwino ogwirizana ndipo amatha kukhala pamodzi ndi zinthu zosiyanasiyana zogwira ntchito, zowonjezera, zopangira ma emulsifiers, ndi zina zambiri popanda zovuta. Izi zimapangitsa kuti azigwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zosamalira khungu. Hydroxyethylcellulose imatha kugwira ntchito yokhazikika pamagawo onse amadzi ndi mafuta.
Hydroxyethylcellulose imagwira ntchito zosiyanasiyana pazosamalira khungu, kuyambira kukhuthala ndi kunyowa mpaka kukhazikika komanso kukonza kukhudza. Zimakhudza pafupifupi ntchito zonse zofunika pakupanga mankhwala osamalira khungu. Kutsika kwake kwa allergenicity ndi kuyanjana kwabwino kwa khungu kumapangitsa kuti ikhale yoyenera pazinthu zosiyanasiyana zosamalira khungu. Kukonda chilengedwe komanso kuwonongeka kwachilengedwe kumagwirizana ndi zomwe msika ukufunikira pazachilengedwe komanso zokhazikika. Mwachidule, hydroxyethylcellulose sikuti amangowonjezera ubwino wa mankhwala osamalira khungu, komanso amakumana ndi zomwe ogula amayembekezera pakuchita bwino kwa mankhwala ndi chitetezo.
