Hydroxyethylulose (HEC) yog feem ntau yog tus neeg sawv cev thiab tus neeg sawv cev hauv ntau yam kev lag luam, suav nrog cov tshuaj pleev ib ce, tshuaj, thiab khoom noj khoom haus. Txawm li cas los xij, nws thawj qhov kev siv tsis yog zaub mov ntxiv, thiab nws tsis yog ib txwm noj ntawm tib neeg los ntawm tib neeg nyob rau hauv cov khoom tseem ceeb. Uas tau hais tias, nws tau txiav txim siab muaj kev nyab xeeb rau kev siv hauv cov khoom noj los ntawm kev tswj hwm lub cev thaum siv raws li qee yam txwv. Ntawm no yog ib qho zoo saib ntawm hydroxyethylcellulose thiab nws txoj kev nyab xeeb profile:
Dab tsi yog hydroxyethylcellulose (HEC)?
Hydroxyethylulose yog tsis-ionic, dej-soluble polymer muab tau los ntawm cellulose, lub ntuj tsim muaj nyob hauv cov nroj tsuag. Nws tau tsim los ntawm kev kho cellulose nrog sodium hydroxide thiab ethylene oxide. Lub txiaj ntsig sib xyaw muaj ntau yam kev thov vim nws lub peev xwm los thicken thiab ua kom muaj kev daws teeb meem, ua kom cov kua ntshiab.
Siv HEC
Cov tshuaj pleev ib ce: HEC feem ntau pom nyob rau hauv cov tshuaj pleev ib ce xws li lotions, cream, tshuaj ntxhua, thiab gels. Nws pab muab kev ntxhib los mos thiab muaj zog rau cov khoom no, txhim kho lawv cov kev ua tau zoo thiab xav txog ntawm daim tawv nqaij lossis plaub hau.
Kws Tshuaj: Hauv cov tshuaj yeeb yaj kiab, hauv cov tshuaj hec yog siv los ua cov tuab, stabilizer, thiab emulsifier hauv ntau cov tshuaj thiab lub qhov ncauj noj.
Kev lag luam khoom noj khoom haus: thaum tsis muaj ntau li hauv cov tshuaj pleev ib ce thiab cov tshuaj, cov khoom noj kom huv, lossis lwm yam kev hnav ris tsho, thiab lwm yam tsis zoo.
Kev nyab xeeb ntawm HEC hauv Cov Khoom Noj Khoom Noj
Kev nyab xeeb ntawm hydroxyethylcellulose nyob rau hauv cov chaw noj zaub mov raug ntsuas los ntawm cov koom haum noj zaub mov noj thiab tshuaj (EFSA), thiab cov koom haum sib xws thoob ntiaj teb. Cov chaw lis haujlwm no feem ntau ntsuas cov zaub mov muaj kev nyab xeeb raws li kev tshawb pom kev paub txog lawv cov txiaj ntsig muaj txiaj ntsig, txhua yam, thiab lwm yam.
1. Kev tswj xyuas tau pom zoo: HEC feem ntau raug lees paub tias muaj kev nyab xeeb (GRAS) rau kev siv hauv cov khoom noj thaum siv tau cov kev tsim khoom zoo thiab tsis pub dhau cov kev txwv. Nws tau raug muab ib tus lej (E1525) los ntawm European Union, qhia tias nws pom zoo raws li cov zaub mov ntxiv.
2. Kev Tshawb Fawb Txog Kev Nyab Xeeb: Txawm tias muaj kev tshawb fawb tshwj xeeb rau kev nyab xeeb ntawm HEC hauv cov khoom noj ntawm cov zaub mov, kev pheej hmoo ntawm cov tshuaj lom neeg thaum noj cov khoom qub. Cellulose derivatives tsis yog metabolized los ntawm tib neeg lub cev thiab raug rho tawm tsis hloov pauv, ua rau lawv feem ntau muaj kev nyab xeeb rau kev noj.
3. Cov koom haum txhua hnub (ADI): Cov chaw tswj hwm tsim tau tsim cov khoom noj muaj tiag (ADD) rau cov zaub mov ntxiv, suav nrog HEC. Qhov no sawv cev tus nqi ntawm cov kev ntxiv uas tuaj yeem noj txhua hnub dhau ib lub neej tsis muaj kev pheej hmoo mob nkeeg hauv lub neej tsis muaj kev pheej hmoo mob nkeeg hauv lub neej yam tsis muaj kev pheej hmoo mob. Tus ADI rau HEC yog raws li kev kawm toxicological thiab tau teeb tsa ntawm qib kev txiav txim siab tsis zoo li ua rau muaj kev phom sij.
Hydroxyethylcellulose yog suav tias muaj kev nyab xeeb rau kev siv hauv cov khoom lag luam thaum siv nyob rau hauv cov lus qhia kev tswj hwm. Thaum nws tsis yog ib hom zaub mov ntxiv thiab yog feem ntau siv nyob rau hauv cov tshuaj pleev ib ce thiab cov chaw muaj kev nyab xeeb, nws tau pom zoo rau kev siv hauv cov ntawv thov zaub mov. Raws li nrog cov zaub mov ntxiv, nws yog qhov tseem ceeb uas siv HEC raws li kev pom zoo siv cov kev pab tsim kom muaj kev nyab xeeb.
