Kodi Hydroxyethylcellulose ndi yotetezeka mu zodzoladzola?

Hydroxyethylcellulose (HEC) ndi polima wamba wosungunuka m'madzi womwe umagwiritsidwa ntchito kwambiri muzodzoladzola ndi zinthu zosamalira anthu. Nthawi zambiri amagwiritsidwa ntchito ngati thickener, stabilizer ndi filimu kale mu mankhwala osiyanasiyana chisamaliro khungu, shampu, shawa gel osakaniza, mafuta odzola, gel osakaniza ndi mankhwala ena. Chitetezo chake chalandira chidwi chofala m'munda wa zodzikongoletsera.

Chemical katundu ndi limagwirira ntchito
Hydroxyethyl cellulose imapangidwa pochiza mapadi ndi sodium hydroxide ndikuyichita ndi ethylene oxide. Cellulose ndi polysaccharide yomwe imapezeka mwachilengedwe muzomera, ndipo kudzera mu njirayi, kusungunuka kwamadzi kwa cellulose kumakulitsidwa, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito popanga madzi. Hydroxyethyl cellulose imakhala ndi mphamvu yokopa kwambiri, yomwe imatha kuwonjezera kukhuthala kwa mankhwalawa, kupangitsa kuti mankhwalawa azikhala osalala komanso osavuta kugwiritsa ntchito. Kuonjezera apo, HEC imapanganso mafilimu ndipo imatha kupanga filimu yotetezera pamwamba pa khungu kapena tsitsi kuti zisawonongeke madzi ndikuchita nawo moisturizing.

Chitetezo cha Hydroxyethyl Cellulose
Chitetezo cha hydroxyethyl cellulose chawunikidwa ndi mabungwe ambiri ovomerezeka. Malinga ndi kuwunika kwa Cosmetic Ingredient Review Committee (CIR) ku United States ndi European Cosmetic Regulation (EC No 1223/2009), Hydroxyethylcellulose imatengedwa ngati chodzikongoletsera chotetezeka. M'mikhalidwe yovomerezeka yogwiritsira ntchito, HEC sichikuvulaza thanzi laumunthu.

Maphunziro a Toxicological: Kafukufuku wambiri wa toxicological awonetsa kuti Hydroxyethyl cellulose siyambitsa kuyabwa pakhungu kapena kuyabwa. Palibe mayeso owopsa a kawopsedwe kapena kuyezetsa kwanthawi yayitali komwe kwapeza HEC kukhala carcinogenic, mutagenic kapena poizoni yobereka. Choncho, ambiri amaonedwa kuti ndi ofatsa komanso osavulaza khungu ndi maso.

Mayamwidwe Pakhungu: Chifukwa cha kulemera kwake kwa mamolekyulu akulu, Hydroxyethylcellulose sangathe kudutsa chotchinga pakhungu ndikulowa m'thupi mwadongosolo. Ndipotu, HEC imapanga filimu yoteteza pambuyo pa ntchito, yotsalira pakhungu popanda kulowa mkati mwa khungu. Chifukwa chake, sizimayambitsa machitidwe amthupi la munthu, zomwe zimawonjezera chitetezo chake.

Chitetezo cha chilengedwe: Hydroxyethyl cellulose ndi biodegradable m'chilengedwe ndipo sizidzawononga kwa nthawi yayitali chilengedwe. Chitetezo chake cha chilengedwe chadziwikanso ndi mabungwe oteteza zachilengedwe.

Kugwiritsa ntchito ndi kuwunika kwachitetezo muzodzola
Kuchuluka kwa hydroxyethyl cellulose mu zodzoladzola nthawi zambiri kumakhala kochepa, nthawi zambiri kumakhala pakati pa 0.1% ndi 2%. Kugwiritsidwa ntchito kotereku kumakhala pansi kwambiri pachitetezo chake chodziwika bwino, kotero ndikotetezeka kugwiritsa ntchito pazigawo izi. Chifukwa cha kukhazikika kwake komanso kuyanjana kwabwino, HEC imagwiritsidwa ntchito kwambiri muzodzola zosiyanasiyana kuti ipititse patsogolo mawonekedwe ndi zomwe ogwiritsa ntchito azigwiritsa ntchito.

Ma cellulose a Hydroxyethyl ndiwogwiritsidwa ntchito kwambiri komanso otetezeka kwambiri pazodzikongoletsera. Kaya mukugwiritsa ntchito nthawi yayitali kapena kukhudzana kwanthawi yayitali, HEC sikuwonetsa kuvulaza thanzi laumunthu. Panthawi imodzimodziyo, kuyanjana kwake ndi chilengedwe kumapangitsanso kukhala chokongoletsera chodziwika bwino masiku ano monga chitukuko chokhazikika komanso chidziwitso cha chilengedwe chikuwonjezeka pang'onopang'ono. Ogula sayenera kuda nkhawa ndi chitetezo chake akamagwiritsa ntchito zinthu zomwe zili ndi hydroxyethyl cellulose, ndipo amatha kusangalala ndikugwiritsa ntchito bwino komanso zotsatira zomwe zimabweretsa.
