Yazisa:
IHydroxyethylcellulose (HEC) yipolymer eguquguqukayo neguquguqukayo kushishino lweekhemikhali zabathengi, idlala indima ebalulekileyo ekuzinziseni ukwakheka kunye nokulawula i-viscosity.Njengoko i-polymer e-soluble yamanzi ephuma kwi-cellulose, i-HEC ineempawu ezizodwa ezenza ukuba zilungele usetyenziso oluhlukeneyo.
Qonda ubume bemolekyuli yeHEC:
I-HEC yi-derivative ye-cellulose, eyona nto ininzi i-polymer yezinto eziphilayo emhlabeni, efunyenwe ngokuyinhloko kwiindonga zeeseli zezityalo.Ngoluhlu lweekhemikhali zokuguqulwa, i-ethylene oxide ifakwe kwi-cellulose ukwenza i-hydroxyethyl cellulose.Oku kuguqulwa kwenza ukuba i-polymer i-soluble emanzini, iyenze ilungele uluhlu olubanzi lwezicelo.
Isakhiwo se-molecular ye-HEC siqukethe i-cellulose backbone kunye namaqela e-hydroxyethyl afakwe kwi-hydroxyl (-OH) amaqela asebenzayo eeyunithi ze-glucose.Esi sakhiwo esiyingqayizivele sinika i-HEC zombini iipropati ze-hydrophilic kunye ne-hydrophobic, evumela ukuba idibane namanzi kunye nezinye izinto kwiintlobo ezahlukeneyo zokuqulunqa.
Uzinzo kwimichiza yasekhaya:
Uzinzo luyinto ephambili ekuqulunqweni kwe-shampoos, i-lotions, i-creams kunye nezinye iimveliso zokuthambisa imihla ngemihla.I-HEC inokusebenza njenge-stabilizer esebenzayo ngenxa yokukwazi ukutshintsha iimpawu ze-rheological zokuqulunqwa, ukukhusela ukuhlukana kwesigaba kunye nokugcina ingqibelelo yemveliso.
Uzinzo lwe-Emulsion:
I-HEC iphucula ukuzinza kwe-emulsion ngokwenza ifilimu ekhuselayo malunga namaconsi eoli ukukhusela ukubambisana.Oku kubaluleke kakhulu kwiimveliso ezifana ne-creams kunye ne-lotions, njengoko izithambiso ezizinzile ziqinisekisa ukusabalalisa izithako.
Uzinzo lokunqunyanyiswa:
Kwiimveliso eziqukethe iinqununu ezimisiweyo, ezifana ne-exfoliating scrubs okanye i-makeup, i-HEC inceda ukugcina iinqununu zihlakazekile kwaye zikhusele ukuhlalisa.Oku kunceda ukuphucula ukuzinza ngokubanzi kunye ne-aesthetics yemveliso.
pH uzinzo:
I-HEC isebenza njenge-buffer ekuqulunqweni, inceda ukuzinzisa nokugcina i-pH yemveliso.Oku kubalulekile kwiimveliso zokhathalelo lomntu, njengoko i-pH ichaphazela ukuhambelana kwesikhumba kunye nokusebenza kwezithako ezisebenzayo.
Ulawulo lwe-Viscosity kwiikhemikhali zemihla ngemihla:
I-Viscosity yiparameter ebalulekileyo emisela iimpawu zokuhamba kweemveliso zemichiza yemihla ngemihla.I-HEC inikeza ulawulo olusebenzayo lwe-viscosity ngokuguqula ubukhulu kunye nokuthungwa kokuqulunqwa.
Thickener:
I-HEC isetyenziswa ngokuqhelekileyo njenge-ejenti yokuqina kwiimveliso ezifana ne-shampoo kunye nokuhlamba umzimba.Inika i-viscosity efunwayo, iphucula ukuthungwa kwemveliso kwaye yenza kube lula ukuyisebenzisa.
Isilungisi sobume:
Iimpawu ze-rheological ze-HEC zinokuthi zenziwe ngokwezifiso ukuze zifezekise ukuthungwa okuthe ngqo ekuqulunqweni.Oku kunenzuzo ngokukodwa kwiimveliso ezifana ne-creams kunye ne-lotions, apho ukuhambelana okufunekayo kunye nokusabalalisa kubaluleke kakhulu ekwanelisekeni kwabathengi.
ulawulo lokuqukuqela:
Kwiimveliso zolwelo ezifana nesepha yesandla okanye ukuhlamba umzimba, i-HEC inceda ukulawula iimpawu zokuhamba ukuze kuqinisekiswe ukuhanjiswa kwemveliso ngokulula nangokungaguquguqukiyo.
ukuququmbela:
Isishwankathelo, i-hydroxyethylcellulose (HEC) idlala indima ephambili kwishishini lemichiza yeekhemikhali, igalelo ekuzinziseni nasekulawuleni i-viscosity yeefom ezahlukeneyo.Isakhiwo sayo esikhethekileyo se-molekyuli, ephuma kwi-cellulose, inika iintlobo ezahlukeneyo zeepropathi ezenza ukuba ibe sisithako esiyimfuneko kwiintlobo ezahlukeneyo zokhathalelo lomntu kunye neemveliso zokuthambisa.Njengoko ulindelo lwabathengi luqhubeka nokuguquka, ukubaluleka kwe-HEC ekugcineni ukuzinza kunye nokusebenza kweemichiza zemihla ngemihla kunokwenzeka ukuba kwandiswe, kuqiniswe isikhundla sayo njengesithako esibalulekileyo kwishishini.
