HEC (Hydroxyethylcellulose) yog cov dej-soluble polymer compound hloov los ntawm ntuj cellulose. Nws yog dav siv hauv cov qauv tshuaj pleev ib ce, feem ntau yog cov thickener, stabilizer thiab emulsifier los txhim kho cov khoom zoo thiab cov nyhuv. Raws li tsis yog-ionic polymer, HEC tshwj xeeb tshaj yog ua haujlwm hauv cov tshuaj pleev ib ce.
1. Cov khoom tseem ceeb ntawm HEC
HEC yog hloov kho cellulose derivative tsim los ntawm reacting natural cellulose nrog ethoxylation. Nws yog xim tsis muaj ntxhiab, tsis muaj ntxhiab, dawb hmoov nrog dej solubility zoo thiab ruaj khov. Vim muaj coob tus ntawm hydroxyethyl pawg nyob rau hauv nws cov qauv molecular, HEC muaj zoo heev hydrophilicity thiab muaj peev xwm tsim hydrogen bonds nrog dej molecules los txhim kho cov kev ntxhib los mos thiab kev xav ntawm cov mis.
2. Thickening nyhuv
Ib qho kev siv ntau tshaj plaws ntawm AnxinCel®HEC yog ua cov thickener. Vim nws cov qauv macromolecular, HEC tuaj yeem tsim cov qauv colloidal hauv dej thiab nce cov viscosity ntawm cov tshuaj. Hauv cov qauv tshuaj pleev ib ce, HEC feem ntau yog siv los kho qhov sib xws ntawm cov khoom xws li tshuaj pleev, gels, cream thiab tshuaj ntxuav, ua kom yooj yim rau kev thov thiab nqus.
Ntxiv HEC rau cov tshuaj pleev ib ce thiab cov tshuaj pleev ib ce tuaj yeem ua rau kev ntxhib los mos ntawm cov khoom smoother thiab fuller, thiab nws tsis yooj yim rau ntws thaum siv, uas txhim kho cov neeg siv khoom. Rau cov khoom siv tu, xws li tshuaj ntxuav lub ntsej muag thiab tshuaj zawv plaub hau, cov nyhuv thickening ntawm HEC tuaj yeem ua rau cov npuas dej ntau dua thiab muag heev, thiab ua rau kom muaj zog thiab ua haujlwm zoo ntawm cov khoom.
3. Txhim kho rheological zog
Lwm lub luag haujlwm tseem ceeb ntawm HEC hauv tshuaj pleev ib ce yog txhim kho rheological zog. Rheological zog hais txog qhov deformation thiab ntws cov khoom ntawm ib yam khoom nyob rau hauv kev ua ntawm sab nraud quab yuam. Rau cov tshuaj pleev ib ce, cov khoom zoo rheological tuaj yeem ua kom muaj kev ruaj ntseg thiab yooj yim ntawm kev siv cov khoom hauv ntau qhov chaw. HEC kho qhov fluidity thiab adhesion ntawm cov mis los ntawm kev cuam tshuam nrog dej molecules thiab lwm yam khoom xyaw mis. Piv txwv li, tom qab HEC ntxiv rau lub emulsion, lub fluidity ntawm emulsion tuaj yeem hloov kho kom nws tsis dhau nyias los yog khov heev, ua kom muaj kev sib kis tau zoo thiab nqus tau.
4. Emulsion stability
HEC kuj tseem siv tau rau hauv emulsion thiab gel tshuaj pleev ib ce ua emulsifier stabilizer. Emulsion yog ib qho system uas muaj cov dej theem thiab roj theem. Lub luag haujlwm ntawm emulsifier yog sib tov thiab stabilize ob yam khoom tsis sib xws ntawm dej thiab roj. HEC, raws li cov khoom hnyav molecular, tuaj yeem txhim kho cov qauv kev ruaj ntseg ntawm cov emulsion los ntawm kev tsim cov qauv sib txuas thiab tiv thaiv dej thiab roj sib cais. Nws cov nyhuv thickening pab kom stabilize lub emulsification system, yog li ntawd cov khoom yuav tsis stratify thaum lub sij hawm cia thiab siv, thiab tuav ib tug zoo nkauj zoo nkauj thiab nyhuv.
HEC tseem tuaj yeem ua haujlwm sib koom ua ke nrog lwm cov emulsifiers hauv cov mis los txhim kho kev ruaj ntseg thiab moisturizing nyhuv ntawm emulsion.
5. Moisturizing nyhuv
Cov nyhuv moisturizing ntawm HEC hauv tshuaj pleev ib ce yog lwm txoj haujlwm tseem ceeb. Cov pab pawg hydroxyl muaj nyob rau hauv HEC molecule tuaj yeem tsim hydrogen bonds nrog dej molecules, pab nqus thiab kaw hauv cov dej noo, thiab yog li ua lub luag haujlwm moisturizing. Qhov no ua rau HEC yog cov khoom siv moisturizing zoo tshaj plaws, tshwj xeeb tshaj yog nyob rau lub caij qhuav lossis hauv cov khoom tu tawv nqaij qhuav, uas tuaj yeem tswj cov dej noo ntawm daim tawv nqaij.
HEC feem ntau ntxiv rau cov khoom tu tawv nqaij xws li cream, lotions, thiab essences los txhim kho cov moisturizing thiab softness ntawm daim tawv nqaij. Tsis tas li ntawd, AnxinCel®HEC tseem tuaj yeem pab cov tawv nqaij tsim cov yeeb yaj kiab tiv thaiv, txo cov dej tsis zoo, thiab txhim kho daim tawv nqaij ua haujlwm.
6. Kev nyab xeeb ntawm daim tawv nqaij thiab kev nyab xeeb
HEC yog cov khoom xyaw me me uas feem ntau suav tias tsis ua rau tawv nqaij thiab muaj biocompatibility zoo. Nws tsis ua rau tawv nqaij ua xua lossis lwm yam kev mob tshwm sim thiab tsim nyog rau txhua hom tawv nqaij, tshwj xeeb tshaj yog cov tawv nqaij rhiab. Yog li ntawd, HEC feem ntau siv rau hauv kev saib xyuas menyuam yaus, kev tu tawv nqaij rhiab, thiab lwm yam tshuaj pleev ib ce uas xav tau cov mis mos.
7. Lwm yam teebmeem ntawm daim ntawv thov
HEC kuj tuaj yeem siv los ua tus neeg sawv cev ncua hauv cov tshuaj ntxuav tes los pab tshem tawm cov teeb meem xws li txhuam cov khoom thiab cov khoom cog kom lawv sib npaug hauv cov khoom. Tsis tas li ntawd, HEC kuj tseem siv rau hauv cov tshuaj pleev thaiv hnub los muab lub teeb txheej thiab txhim kho cov tshuaj pleev thaiv hnub.
Nyob rau hauv anti-aging thiab antioxidant khoom, lub hydrophilicity ntawmHEC kuj pab kom nyiam thiab kaw hauv cov dej noo, pab cov khoom xyaw nquag kom nkag mus rau ntawm daim tawv nqaij zoo dua thiab txhim kho cov txiaj ntsig ntawm cov khoom no.
Raws li cov khoom siv tshuaj pleev ib ce, HEC muaj ntau yam teebmeem thiab tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom zoo nkauj, txhim kho rheological zog, txhim kho emulsification stability, thiab muab cov nyhuv moisturizing. Nws txoj kev nyab xeeb thiab kev sib haum xeeb ua rau nws haum rau ntau hom tshuaj pleev ib ce, tshwj xeeb tshaj yog rau cov tawv nqaij qhuav thiab rhiab heev. Raws li kev lag luam tshuaj pleev ib ce qhov kev thov rau cov qauv me me, ua tau zoo, thiab tus phooj ywg ib puag ncig tau nce, AnxinCel®HEC yuav tsis muaj kev poob siab txuas ntxiv mus ua haujlwm tseem ceeb hauv kev kho kom zoo nkauj.
