Hydroxyethyl cellulose (HEC) yog cov tuab thiab stabilizer nquag siv hauv cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej. Nws yog dej-soluble polymer tau los ntawm kev kho cellulation cellulose (lub ntsiab tivthaiv ntawm cov nroj tsuag phab ntsa). Hydroxyethyl cellulose tau siv dav hauv cov tshuaj zawv plaub hau, cov khoom siv, styling thiab cov khoom siv tu tawv nqaij vim yog cov dej muaj peev xwm thiab ncua kev muaj peev xwm.
Cuam tshuam ntawm hydroxyethyl cellulose rau plaub hau
Hauv cov khoom lag luam plaub hau, cov haujlwm tseem ceeb ntawm hydroxyethyl cellulose yog thickening thiab sib sau ua yeeb yaj kiab tiv thaiv:
Thickening: hydroxyethyl cellulose nce viscosity ntawm cov khoom, ua rau nws yooj yim rau kev thov thiab faib rau ntawm cov plaub hau. Txoj cai viscosity kom ntseeg tau tias cov khoom xyaw nquag npog txhua plaub hau strand ntau tusyees ntawm cov khoom lag luam.
Moisturizing: hydroxyethyl cellulose muaj lub peev xwm moisturizing zoo thiab tuaj yeem pab ntsuas kom tiv thaiv cov plaub hau los ntawm kev ziab. Qhov no yog qhov tshwj xeeb tshaj yog rau cov plaub hau qhuav lossis puas los noo kom ntub dej yooj yim dua.
Cov nyhuv tiv thaiv: Ua ib zaj duab xis nyias nyias muaj kev tiv thaiv cov plaub hau los ntawm kev ua yeeb yaj kiab ib puag ncig sab nraud thiab yooj yim dua los ntawm kev rub tawm.
Kev nyab xeeb ntawm hydroxyethyl cellulose rau plaub hau
Hais txog seb hydroxyethyl cellulose muaj kev phom sij rau cov plaub hau, kev ntsuam xyuas kev nyab xeeb uas muaj tseeb ntseeg tias nws muaj kev nyab xeeb. Tshwj xeeb:
Qis chim: hydroxyethyl cellulose yog ib qho tshuaj me me uas tsis zoo li ua rau tawv nqaij lossis tawv taub hau. Nws tsis muaj cov tshuaj lom lossis muaj cov ua xua, ua rau nws haum rau feem ntau cov tawv nqaij thiab cov plaub hau hom, suav nrog cov plaub hau rhiab thiab tsis muaj plaub hau.
Tsis muaj tshuaj lom: cov kev tshawb fawb tau pom tias hydroxyethyl cellulose feem ntau yog siv hauv cov tshuaj pleev ib ce hauv cov tshuaj pleev ib ce tsawg thiab tsis muaj tshuaj lom. Txawm hais tias nqus tau los ntawm tawv taub hau, nws cov metabolites yog tsis muaj mob thiab yuav tsis nra hnyav lub cev.
Zoo biocompatibility: raws li cov compound los ntawm ntuj cellulose, hydroxyethyl cellulose muaj zoo biocompatibility nrog tib neeg lub cev thiab yuav tsis ua rau kev tsis txaus siab. Tsis tas li ntawd, nws yog biodegradable thiab muaj qhov cuam tshuam tsawg ntawm ib puag ncig.
Muaj peev xwm tshwm sim
Txawm hais tias hydroxyethylcellulose feem ntau yog cov teeb meem hauv qab no yuav tshwm sim nyob rau qee kis:
Kev siv ntau dhau yuav ua rau cov neeg nyob hauv cov khoom lag luam hauv hydroxellulose cov ntsiab lus hauv cov plaub hau, nws yuav tawm ntawm cov plaub hau, ua kom cov plaub hau cia li nplaum lossis hnyav. Yog li ntawd, nws pom zoo kom siv nws hauv kev sim raws li cov lus qhia cov khoom lag luam.
Kev sib cuam tshuam nrog lwm cov khoom xyaw: hauv qee kis, hydroxyethylcellulose nrog lwm yam tshuaj lom neeg cov khoom xyaw, ua rau txo cov khoom lag luam tshwj xeeb lossis cov teebmeem tsis tau xav txog. Piv txwv li, qee cov khoom xyaw acidic yuav tawg cov qauv ntawm hydroxyethylcellulose, tsis muaj zog nws cov nyhuv tuab.
Raws li ib qho kev lom zem ua kom zoo nkauj, hydroxyethylcellulose yog tsis muaj mob rau cov plaub hau thaum siv kom raug. Nws tsis tuaj yeem pab txhim kho kev ntxhib los mos thiab siv cov kev paub ntawm cov khoom, tab sis kuj tuaj yeem noo noo, thicken thiab tiv thaiv cov plaub hau. Txawm li cas los xij, tej yam tshuaj muaj yuav tsum siv rau hauv kev sim thiab xaiv cov khoom lag luam zoo raws li koj hom plaub hau thiab xav tau. Yog tias koj muaj kev txhawj xeeb txog cov khoom xyaw hauv qee cov khoom lag luam, pom zoo kom sim ib thaj chaw me lossis sab laj tus kws tshaj lij ntawm tus kws tshaj lij.
