Hydroxyethylulose (HEC) yog qhov siab molecular compound tau los ntawm ntuj cellulose thiab tau siv dav hauv cov tshuaj pleev ib ce thiab cov khoom tu tawv nqaij. Nws muaj zoo hydrophilicity, thickening, emulsification thiab ruaj khov, yog li nws ua lub luag haujlwm tseem ceeb hauv ntau yam kev saib xyuas tawv nqaij.
1. Cov khoom yooj yim ntawm hydroxyethyl cellulose
Hydroxyethyl cellulose yog synthesized los ntawm kev qhia hydroxyethyl pab pawg (-ch2ch2oh) rau hauv cellulose molecular molecular. Cellulose nws tus kheej yog ib qho tshwm sim ntawm lub siab molecular uas tau faib dav hauv cov phab ntsa ntawm tes ntawm cov nroj tsuag. Los ntawm kev hloov kho tshuaj lom neeg, lub hydrophilicity ntawm cellulose yog txhim kho, ua rau nws cov tuab zoo tshaj plaws, stabilizer thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier.
2. Kev tu tawv nqaij ntawm hydroxyethyl cellulose
Thickening thiab txhim kho kev ntxhib los mos
Feem ntau cov haujlwm ntawm hydroxyethyl cellulose hauv cov khoom saib xyuas cov khoom siv tawv nqaij yog ua cov thickener kom nce viscosity ntawm cov khoom. Cov yam ntxwv no tsis tsuas yog txhim kho cov ntawv thov xav tau ntawm cov khoom, tab sis kuj tseem yuav ua rau cov khoom siv muag heev thiab du. Tshwj xeeb tshaj yog nyob rau hauv cov huv huv, moisturizers, cov ntsej muag thiab lwm yam khoom, hydrothethyl cellulose tuaj yeem txhim kho cov ntawv nyeem, thiab nce cov neeg siv kev nplij siab.
Txhim kho emulsification
Hauv ntau cov khoom tu tawv nqaij, qhov ruaj khov ntawm cov roj-dej sib tov yog qhov kev sib tw loj hauv cov qauv siv mis. Hydroxyethyl cellulose tuaj yeem siv los ua emulsifier los ua lub zog ruaj khov ntawm cov roj thiab theem dej, cia ob los sib tov tusyees thiab tiv thaiv nag lossis daus. Cov yeeb yam no yog qhov tseem ceeb rau ntau yam khoom tu tawv nqaij xws li lotions, creamences, uas tuaj yeem ua kom lub sijhawm ntev ntawm cov khoom thiab txhim kho nws cov nyhuv siv.
Moisturizing muaj nuj nqi
Vim nws muaj zog hydrophilicity, hydroxyethyl cellulose tuaj yeem nqus thiab khaws dej, yog li ua lub cev noo. Qhov no ua rau nws ua lub luag haujlwm Irreplacable txoj haujlwm hauv ntau cov tshuaj tua cov tawv nqaij. Nws tuaj yeem tsim cov yeeb yaj kiab dej nyias nyias rau ntawm cov tawv nqaij saum npoo av, ntsuas phoo nyob rau hauv cov dej noo, tiv thaiv kom tsis txhob muaj cov tawv nqaij poob thiab muag muag.
Txhim kho cov tawv nqaij kov
Raws li cov tuab tuab, hydroxyethyl cellulose tsis tuaj yeem kho cov khoom viscosity ntawm cov khoom, tab sis kuj txhim kho kev lom zem thiab smoothness ntawm cov khoom tu tawv nqaij. Tom qab siv cov khoom muaj hydroxyethyl cellulose, cov tawv nqaij saum npoo av feem ntau hnov qab ntxhiab, thiab txhim kho cov neeg siv. Rau qee cov khoom tu cov tawv nqaij uas yog oily lossis nplaum, ntxiv rau cov tib neeg nrog cov tawv nqaij sib txawv, nws tuaj yeem siv ntau dua kev xav.
Kev mob me thiab kev siv dav dav
Hydroxyethyl cellulose nws tus kheej muaj qhov me me thiab tsis tshua muaj kev ua rau tawv nqaij, yog li nws yog qhov tsim nyog siv rau hauv cov tawv nqaij tawv nqaij rau cov tawv nqaij rhiab. Nws tsis ua rau ua xua lossis voos thiab haum rau txhua hom tawv nqaij, suav nrog cov tawv nqaij qhuav, thiab rhiab. Ib qho ntxiv, raws li cov tsis-ionic polymer, hydroxyethyl cellulose tuaj yeem nyob hauv ntau hom kev saib xyuas cov tawv nqaij.
Txhim Kho Khoom Ruaj Ntseg
Hauv cov qauv ntawm ntau cov khoom siv saib xyuas tawv nqaij, hydroxyethyl cellulose plays lub luag haujlwm ntawm stabilizer. Nws tuaj yeem tiv thaiv kev sib cais, nag lossis daus lossis oxidation ntawm cov khoom xyaw rau hauv cov khoom lag luam lossis cov roj av muaj txiaj ntsig zoo siv cov khoom lag luam thiab ua kom muaj kev siv ntev. Tsis tas li ntawd, hydroxyethyl cellulose tseem tuaj yeem pab txhim kho cov khoom hloov kho tau rau ib puag ncig cov khoom yuav tsis raug puas tsuaj los ntawm ib puag ncig cov khoom.
3. Kev thov ntawm hydroxyethyl cellulose hauv cov khoom tu tawv nqaij
Ntsej muag tshuaj ntxuav
Hauv cov khoom lag luam xws li cov tshuaj ntxuav ntsej muag thiab lub ntsej muag ntxuav cov npuas dej, hydroxyethyl cellulose ua lub luag haujlwm tseem ceeb li cov tuab thiab emulsifier. Nws tuaj yeem hloov kho cov tshuaj viscial ntxuav, kom lawv tuaj yeem siv tau tusyees ua kom zoo thaum siv, thiab tseem tuaj yeem txhim kho qhov kov thiab smoothness ntawm cov khoom.
Ntsej muag daim npog khoom
Hydroxyethyl cellulose tau siv dav hauv ntsej muag ntsej muag, tshwj xeeb tshaj yog hydrogel lub ntsej muag thiab cov ntsej muag me me. Nws tuaj yeem txhim kho cov nplaum ntawm ntsej muag, pab lub ntsej muag cuav npog cov tawv nqaij saum npoo av, thiab txhim kho cov nyhuv yahuab ntawm cov ntsej muag ntsej muag ntsej muag. Nyob rau tib lub sijhawm, nws kuj tseem tuaj yeem pab cov ntsej muag ntsej muag nyob ruaj khov thaum lub sijhawm cia khoom thiab tsis yooj yim tawg lossis delaminated.
Mobicurizers thiab lotions
Nyob rau hauv cov moisturizers thiab muaj cov nyhuv, cov nyhuv thickening ntawm hydroxyethyl cellulose tuaj yeem txhim kho cov ntxhib los yog txhim kho thiab tsis nplaum thaum ua ntawv thov rau daim tawv nqaij. Tsis tas li ntawd, nws cov khoom muaj zog tuaj yeem pab cov tawv nqaij nyob hauv lub sijhawm ntev thiab txhim kho cov kab mob ntawm cov tawv nqaij qhuav.
Cov khoom tiv thaiv hnub ci
Hauv cov tshuaj pleev thaiv hnub, hydroxyethyl cellulose kuj yog siv los kho cov qauv ntawm cov khoom kom nws tuaj yeem ua kom ruaj khov thiab tswj hwm kev ruaj khov thaum thov. Txij li cov khoom tiv thaiv tshav ntuj feem ntau yuav tsum muaj cov ntsiab lus dej siab, hydroxyethyl cellulose tuaj yeem pab khaws cov dej noo thaum tiv thaiv cov qauv los ntawm kev ntaus lossis daws.
Raws li lub siab molecular sib xyaw, hydroxyethyl cellulose muaj ntau lub zog hauv cov khoom tu tawv nqaij. Nws tsis tsuas yog txhim kho cov qauv thiab smootness thiab kuj tseem txhim kho cov txiaj ntsig emulsification, txhim kho kev ruaj khov ntawm cov khoom, thiab yog kev maj mam thiab tsis muaj kev sib xyaw rau daim tawv nqaij. Nrog kev tsim kho cov tawv nqaij txuas ntxiv, daim ntawv thov cov xwm txheej ntawm hydropyethyl cellulose yuav dhau los thiab muaj ib qho ntawm cov khoom xyaw tsis tau muaj nyob rau hauv cov khoom tu tawv niaj hnub.
