Hydroxyethyl cellulose vs xanthan chingamu

Hydroxyethyl cellulose (HEC) ndi xanthan chingamu ndi mitundu iwiri yosiyanasiyana ya thickeners yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo mafakitale a zakudya, mankhwala, ndi zodzoladzola.Ma thickeners onsewa ndi ma polima osungunuka ndi madzi omwe amatha kuwonjezera kukhuthala komanso kukhazikika kwa mayankho.Komabe, amasiyana malinga ndi zomwe ali nazo komanso momwe amagwiritsidwira ntchito.M'nkhaniyi, tiyerekeza hydroxyethyl cellulose ndi xanthan chingamu, kukambirana katundu wawo, ntchito, ndi ntchito.

Ma cellulose a Hydroxyethyl (HEC)

Hydroxyethyl cellulose ndi nonionic cellulose ether yochokera ku cellulose kudzera mu kuwonjezera kwa magulu a hydroxyethyl ku msana wa cellulose.HEC imagwiritsidwa ntchito ngati thickener, stabilizer, ndi emulsifier m'mafakitale osiyanasiyana, kuphatikizapo mafakitale a zakudya, mankhwala, ndi zodzoladzola.

HEC ili ndi maubwino angapo kuposa mitundu ina ya thickeners.Ili ndi mamasukidwe apamwamba kwambiri ndipo imatha kupanga mayankho omveka bwino pamagawo otsika.Komanso kwambiri sungunuka m'madzi ndi n'zogwirizana ndi osiyanasiyana zosakaniza zina.Komanso, HEC akhoza kusintha bata la emulsions ndi suspensions, kupanga izo zothandiza zosiyanasiyana formulations.

HEC imagwiritsidwa ntchito kwambiri m'makampani opanga zodzikongoletsera kuti apititse patsogolo mawonekedwe komanso kusasinthika kwazinthu zosamalira anthu, monga ma shampoos, zowongolera, zodzola, ndi zonona.Itha kukhalanso ngati woyimitsa, emulsifier, ndi binder.HEC imathandiza makamaka pazitsulo zosamalira tsitsi, chifukwa zimatha kupereka mawonekedwe osalala komanso okoma kwambiri omwe amathandizira kufalikira kwa mankhwalawa.

Xanthan Gum

Xanthan chingamu ndi polysaccharide yomwe imapangidwa ndi kuwira kwa mabakiteriya a Xanthomonas campestris.Nthawi zambiri amagwiritsidwa ntchito ngati thickener ndi stabilizer muzakudya, mankhwala, ndi zodzikongoletsera.Xanthan chingamu ndi polysaccharide yolemera kwambiri yama cell, yomwe imapangitsa kuti ikhale yolimba.

Xanthan chingamu ali ndi ubwino angapo monga thickener.Ili ndi mamasukidwe apamwamba kwambiri ndipo imatha kupanga ma gels pamagulu otsika.Imasungunukanso kwambiri m'madzi ndipo imatha kupirira kutentha kosiyanasiyana komanso ma pH.Komanso, xanthan chingamu akhoza kusintha bata emulsions ndi suspensions, kupanga izo zothandiza zosiyanasiyana formulations.

Xanthan chingamu chimagwiritsidwa ntchito kwambiri m'makampani azakudya ngati kunenepa komanso kukhazikika muzinthu zosiyanasiyana, kuphatikiza mavalidwe a saladi, sosi, ndi zinthu zophika buledi.Amagwiritsidwanso ntchito m'makampani opanga mankhwala ngati kuyimitsa komanso m'makampani opanga zodzoladzola monga thickener ndi stabilizer muzinthu zosiyanasiyana zosamalira anthu, monga mafuta odzola ndi mafuta.

Kuyerekezera

HEC ndi xanthan chingamu zimasiyana m'njira zingapo.Kusiyanitsa kumodzi kwakukulu ndiko gwero la polima.HEC imachokera ku cellulose, polima yachilengedwe yomwe imapezeka muzomera, pomwe xanthan chingamu imapangidwa ndi nayonso mphamvu ya mabakiteriya.Kusiyana kwa gwero kungakhudze katundu ndi ntchito za thickeners awiri.

Kusiyana kwina pakati pa HEC ndi xanthan chingamu ndi kusungunuka kwawo.HEC imasungunuka kwambiri m'madzi ndipo imatha kupanga mayankho omveka bwino pamagawo otsika.Xanthan chingamu imasungunukanso kwambiri m'madzi, koma imatha kupanga ma gels pamalo otsika.Kusiyana kwa kusungunuka kumeneku kungakhudze kapangidwe kake ndi kusasinthasintha kwa mapangidwe omwe ali ndi zokometsera izi.

Kukhuthala kwa HEC ndi xanthan chingamu kumasiyananso.HEC ili ndi kukhuthala kwakukulu, komwe kumapangitsa kuti ikhale yothandiza ngati thickener mumitundu yosiyanasiyana.Xanthan chingamu chili ndi mamasukidwe otsika kuposa HEC, koma imatha kupanga ma gels pamiyeso yotsika.
