Hydroxyethyl Cellulose (HEC) ndi mankhwala omwe amagwiritsidwa ntchito kwambiri posamalira khungu. Ndizochokera ku cellulose ndipo zimakhala zokhuthala bwino komanso zokhazikika. Amagwiritsidwa ntchito kwambiri mu zodzoladzola, zodzola, zotsuka, ndi zinthu zina zosamalira khungu makamaka chifukwa chakumamatira kwake, kumva kwake kwa silky, komanso kunyowetsa. Ngakhale kuti ilibe mwachindunji zochita zamankhwala kapena machiritso paokha, kugwiritsa ntchito kwake pazinthu zosamalira khungu kumakhudza kwambiri chitonthozo cha khungu ndi kapangidwe kake.
1. Ntchito ya thickeners ndi stabilizers
Hydroxyethyl cellulose imagwiritsidwa ntchito kwambiri pazinthu zosamalira khungu ngati thickener ndi stabilizer. Cholinga cha thickener ndi kuthandiza mankhwala kukhala ndi mawonekedwe ofanana, kuteteza kusanjikiza kapena kupatukana, ndi kupanga mankhwala mosavuta kuika ndi kuyamwa. Popeza zinthu zambiri zosamalira khungu (monga mafuta odzola, ma gels, zonona, ndi zina zotero) zimakhala ndi madzi ndi mafuta, hydroxyethyl cellulose ingathandize kuti zinthuzi zisakanizike pamodzi mokhazikika ndikupereka mwayi wogwiritsa ntchito bwino. Mapangidwe okhazikikawa amatha kulepheretsa kuti zinthu zosamalira khungu zisawonongeke panthawi yosungira, kupititsa patsogolo moyo wa alumali komanso kuchita bwino kwa mankhwalawa.
2. Kupititsa patsogolo ntchito
Ma cellulose a Hydroxyethyl ali ndi zinthu zina zonyowa. Ikhoza kupanga filimu yochepetsetsa yotetezera kuti khungu likhalebe ndi chinyezi. Chophatikizirachi nthawi zambiri chimagwiritsidwa ntchito posamalira khungu ndi ma formula opanda mafuta kuti apereke mawonekedwe osalala komanso omasuka popanda kuwonjezera mafuta. Itha kupangitsa kugwiritsa ntchito mankhwala osamalira khungu kukhala osalala, kupititsa patsogolo luso lazogwiritsa ntchito, ndikupangitsa kuti chisamaliro cha khungu chikhale chosangalatsa.
3. Waubwenzi kwa khungu tcheru
Hydroxyethyl cellulose ndi wofatsa, hypoirritating pophika, kupanga kukhala oyenera mitundu yonse ya khungu, kuphatikizapo tcheru khungu. Sichimakonda kuyambitsa kuyabwa kapena kupsa mtima, chifukwa chake chimapezeka m'njira zambiri. Izi zimapangitsa hydroxyethylcellulose kukhala chisankho chabwino kwa anthu ambiri omwe ali ndi zotchinga pakhungu zomwe zimasokonekera kapena tcheru. Chosakaniza ichi chimagwiritsidwanso ntchito nthawi zambiri pakusamalira khungu la ana komanso zinthu zoyeretsera pakhungu lodziwika bwino chifukwa ndi lofatsa komanso la hypoallergenic.
4. Limbikitsani zonyowa za mankhwalawa
Ngakhale hydroxyethylcellulose palokha si moisturizer wamphamvu, angathandize kuchepetsa kutaya chinyezi pakhungu popanga filimu zoteteza. Chotchinga ichi chimakhala choyenera makamaka pakhungu louma komanso pamene chilengedwe chimakhala chovuta (monga kuzizira kapena kowuma). Mukaphatikizidwa ndi zinthu zina zowonjezera (monga glycerin, hyaluronic acid, etc.), hydroxyethyl cellulose imatha kupititsa patsogolo mphamvu yamadzimadzi ndikuthandizira khungu kukhala lofewa komanso lopanda madzi.
5. Palibe katundu wa zosakaniza yogwira
Ngakhale kuti hydroxyethylcellulose ikhoza kubweretsa kumverera bwino kwa ntchito ndi zotsatira zina zonyowa, sizinthu zogwira ntchito, ndiko kuti, sizimakhudzidwa mwachindunji ndi maselo a khungu kapena kulimbikitsa kukonza khungu ndi kusinthika. Chifukwa chake, gawo la cellulose ya hydroxyethyl muzinthu zosamalira khungu ndikupatsanso mawonekedwe abwino komanso mawonekedwe osavuta akhungu, m'malo mothana ndi vuto linalake lapakhungu (monga makwinya, utoto kapena ziphuphu).
6. Chepetsani kuyabwa pakhungu
Zomwe zimagwiritsidwa ntchito muzinthu zina zosamalira khungu (monga ma asidi, mavitamini A, ndi zina zotero) zingayambitse khungu, makamaka pakhungu. Ma cellulose a Hydroxyethyl amatha kuchepetsa kupsa mtima kwa zinthu zomwe zimagwira pakhungu. Imakhala ngati matrix osagwira ntchito kuti athandizire kuchepetsa mphamvu ya zinthu zomwe zimagwira ntchito ndikusunga mphamvu ya mankhwalawa.
7. Ecology ndi chitetezo
Hydroxyethyl cellulose ndi zinthu zomwe zimatha kuwonongeka kuchokera ku cellulose ya zomera ndipo ndizogwirizana ndi chilengedwe. Izi zikutanthauza kuti sizikhala ndi zotsatira zoyipa zokhalitsa pazachilengedwe zitagwiritsidwa ntchito ngati mankhwala opangira. Kuphatikiza apo, akatswiri ambiri a dermatologists ndi akatswiri osamalira khungu amawona kuti ndizoyenera kugwiritsa ntchito nthawi yayitali.
Udindo wa hydroxyethyl cellulose muzinthu zosamalira khungu umawonekera makamaka pakukweza mawonekedwe, kunyowa komanso kukhazikika kwa chinthucho. Ngakhale kuti sichimathetsa mavuto a khungu pa seme, ndi yabwino kwa mitundu yonse ya khungu, makamaka khungu lovuta, chifukwa cha kupsa mtima kwake, zinthu zochepa komanso zopatsa mphamvu zabwino. Panthawi imodzimodziyo, zimathandiza kuti zinthu zina zomwe zimagwiritsidwa ntchito pazitsulo zizigwira ntchito bwino pakhungu, kuchepetsa kupsa mtima komwe kungayambitse. Chifukwa chake, kugwiritsa ntchito hydroxyethyl cellulose muzinthu zambiri zosamalira khungu kumapatsa ogwiritsa ntchito chidziwitso chosangalatsa chapakhungu ndipo amathandizira kuti khungu lisunge chinyezi komanso chitonthozo.
