Hydroxyethyl Cellulose (HEC) yog cov thickener thiab stabilizer feem ntau siv hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej. Nws yog cov dej-soluble polymer tau los ntawm kev hloov kho cellulose (lub ntsiab ntawm cov phab ntsa ntawm cov nroj tsuag). Hydroxyethyl Cellulose yog siv dav hauv cov tshuaj zawv plaub hau, tshuaj kho mob, cov khoom siv styling thiab cov khoom tu tawv nqaij vim nws cov dej noo zoo heev, thickening thiab ncua kev muaj peev xwm.
Cov teebmeem ntawm Hydroxyethyl Cellulose ntawm Cov plaub hau
Hauv cov khoom tu plaub hau, lub luag haujlwm tseem ceeb ntawm Hydroxyethyl Cellulose yog thickening thiab tsim cov yeeb yaj kiab tiv thaiv:
Thickening: Hydroxyethyl Cellulose tsub kom lub viscosity ntawm cov khoom, ua rau nws yooj yim rau thov thiab faib rau cov plaub hau. Txoj cai viscosity xyuas kom meej tias cov khoom xyaw nquag npog txhua cov plaub hau sib npaug, yog li ua kom cov khoom siv tau zoo.
Moisturizing: Hydroxyethyl Cellulose muaj peev xwm moisturizing zoo thiab tuaj yeem pab ntsuas cov dej noo kom tiv thaiv cov plaub hau kom qhuav thaum ntxuav. Qhov no yog tshwj xeeb tshaj yog ib qho tseem ceeb rau cov plaub hau qhuav los yog puas, uas nyiam poob noo noo yooj yim dua.
Cov nyhuv tiv thaiv: Kev tsim cov yeeb yaj kiab nyias ntawm cov plaub hau yuav pab tiv thaiv cov plaub hau los ntawm kev puas tsuaj rau sab nraud, xws li cov pa phem, hluav taws xob ultraviolet, thiab lwm yam. Cov yeeb yaj kiab no kuj ua rau cov plaub hau smoother thiab yooj yim rau zuag, txo kev puas tsuaj los ntawm kev rub.
Kev nyab xeeb ntawm hydroxyethyl cellulose ntawm cov plaub hau
Hais txog seb hydroxyethyl cellulose puas tsim kev puas tsuaj rau cov plaub hau, kev tshawb fawb tshawb fawb thiab kev ntsuam xyuas kev nyab xeeb feem ntau ntseeg tias nws muaj kev nyab xeeb. Tshwj xeeb:
Kev khaus qis: Hydroxyethyl cellulose yog cov khoom xyaw me me uas tsis zoo li yuav ua rau tawv nqaij lossis tawv taub hau. Nws tsis muaj tshuaj lom neeg lossis muaj peev xwm ua xua, ua rau nws haum rau feem ntau cov tawv nqaij thiab plaub hau hom, nrog rau cov tawv nqaij rhiab heev thiab cov plaub hau tsis yooj yim.
Tsis muaj tshuaj lom: Cov kev tshawb fawb tau pom tias hydroxyethyl cellulose feem ntau yog siv rau hauv cov tshuaj pleev ib ce hauv cov nqi qis thiab tsis muaj tshuaj lom. Txawm hais tias nqus los ntawm tawv taub hau, nws cov metabolites tsis muaj teeb meem thiab yuav tsis ua rau lub cev hnyav.
Zoo biocompatibility: Raws li ib tug compound muab los ntawm tej yam ntuj tso cellulose, hydroxyethyl cellulose muaj biocompatibility zoo nrog tib neeg lub cev thiab yuav tsis ua rau rejection tshwm sim. Tsis tas li ntawd, nws yog biodegradable thiab muaj kev cuam tshuam tsawg rau ib puag ncig.
Tej yam tshwm sim
Txawm hais tias hydroxyethylcellulose muaj kev nyab xeeb nyob rau hauv feem ntau, cov teeb meem hauv qab no yuav tshwm sim hauv qee kis:
Kev siv ntau dhau yuav ua rau muaj qhov seem: yog tias cov ntsiab lus hydroxyethylcellulose hauv cov khoom yog siab dhau los yog siv ntau dhau, nws tuaj yeem tso cov khoom seem ntawm cov plaub hau, ua rau cov plaub hau nplaum los yog hnyav. Yog li ntawd, nws raug nquahu kom siv nws nyob rau hauv ib nrab raws li cov lus qhia ntawm cov khoom.
Kev sib cuam tshuam nrog lwm cov khoom xyaw: Qee zaum, hydroxyethylcellulose tuaj yeem cuam tshuam nrog qee cov khoom xyaw tshuaj, ua rau txo cov khoom lag luam lossis cov txiaj ntsig tsis xav txog. Piv txwv li, qee cov khoom xyaw acidic tuaj yeem rhuav tshem cov qauv ntawm hydroxyethylcellulose, ua rau nws cov nyhuv thickening.
Raws li cov khoom siv tshuaj pleev ib ce, hydroxyethylcellulose tsis muaj teeb meem rau cov plaub hau thaum siv kom raug. Nws tuaj yeem tsis tsuas yog pab txhim kho kev ntxhib los mos thiab siv kev paub ntawm cov khoom, tab sis kuj moisturize, thicken thiab tiv thaiv cov plaub hau. Txawm li cas los xij, txhua yam khoom siv yuav tsum tau siv rau hauv kev ua kom zoo thiab xaiv cov khoom tsim nyog raws li koj hom plaub hau thiab xav tau. Yog tias koj muaj kev txhawj xeeb txog cov khoom xyaw hauv ib yam khoom, nws raug nquahu kom kuaj xyuas thaj chaw me me lossis nrog tus kws kho mob dermatologist.
