HEC for Cosmetics and Personal Care

Hydroxyethyl cellulose HEC ndi gawo lofunikira mu zodzoladzola ndi chisamaliro chaumwini. The solubility ndi mamasukidwe akayendedwe katundu wa hydroxyethyl mapadi HEC thandizani mokwanira kuti mukhale oyenerera, kotero kuti mawonekedwe oyambirira a zodzoladzola akhoza kusungidwa ngakhale nyengo yotentha ndi yozizira. Kuonjezera apo, ili ndi mphamvu zowonongeka ndipo ndizofala muzodzoladzola zonyowa. Makamaka chigoba cha nkhope, tona ndi zina zotero zatsala pang'ono kuwonjezeredwa.

Zodzoladzola, monga mtundu wa mankhwala okhudzana mwachindunji pakhungu, ogwiritsa ntchito amapereka chidwi chapadera pa kapangidwe kake ndi chitetezo cha zosakaniza zomwe ali nazo kuwonjezera pa kukongola kwawo ndi ntchito zosamalira khungu.

Chaniis hydroxyethyl celluloseHEC?

HECHydroxyethyl cellulose ndi yoyera kapena yotumbululuka yachikasu, yopanda kukoma, yopanda poizoni kapena yolimba. Mu kaphatikizidwe ka mafakitale ndi labotale, cellulose yoyambira ndi ethylene oxide (kapena chloroethanol) nthawi zambiri amapangidwa ndi etherification reaction.

Katundu ndi ntchito zaHEC:

HEC ili ndi zinthu zabwino zowonjezera kukhuthala, sing'anga yunifolomu, yankho la emulsifying, kugwirizana, komanso kuchepetsa kusungunuka kwa chinyezi ndi kupereka colloid yoteteza.

Udindo pa HEC mu zodzoladzola

zodzikongoletsera zili m'mitundu yonse yazinthu zachilengedwe kapena zopanga zamafakitale zovuta zopangira mankhwala, komanso zinthu zakuthupi ndi zamankhwala pakati pa ogwirizana, popanga zodzoladzola zomwe zimapanga zofunikira kuwonjezeraHEC as emulsifier, zomatira zimatha kupanga mitundu ya zosakaniza kukhala pulasitiki nthawi zonse. Pogwiritsidwa ntchito, zodzoladzola zimathanso kutengera mitundu yosiyanasiyana ya khungu komanso kutentha ndi chinyezi m'malo. Pofuna kukulitsa kusinthika kwa msika komanso kugwiritsa ntchito kwa ogula. The hydrating katundu waHEChydroxyethyl cellulose imathandizanso kuti khungu likhale lopanda madzi.

Water-soluble polima pawiri ntchito mu zodzoladzola

Pali magulu achilengedwe komanso opangidwa. Mankhwala a polima osungunuka ndi madzi ndi awa: wowuma, chingamu cha zomera, gelatin ya nyama, ndi zina zotero, koma khalidwe lake ndi losakhazikika, losasunthika ku nyengo, malo, malo, zokolola zochepa, komanso zosatetezeka ku mabakiteriya, nkhungu ndi metamorphic effect.HECHydroxyethyl cellulose synthesis of water-soluble polymer compounds: polyvinyl alcohol, poly (ethylene) Pyrrolidone, khola, kukwiya kochepa kwa khungu, mtengo wotsika, kotero m'malo mwa mankhwala achilengedwe osungunuka a polima amakhala gwero lalikulu la zipangizo za colloid. Imagawidwa mu semi-synthetic ndi kupanga polima zosungunuka m'madzi. Ma semi-synthetic polima osungunuka m'madzi amagwiritsidwa ntchito nthawi zambiri: methyl cellulose, ethyl cellulose, carboxymethyl fiber.,Vitamini sodium,HEChydroxyethyl cellulose, chingamu ndi zotulukapo zake. Kaphatikizidwe wamadzi osungunuka polima mankhwala omwe amagwiritsidwa ntchito kwambiri: mowa wa polyvinyl, polyvinylpyrrolidone, acrylic acid polima. Izi ntchito zodzoladzola monga zomatira, thickeners, mafilimu akale, emulsifying stabilizers.
