Kwizinto zokuthambisa, zininzi iikhemikhali ezingenambala nezingenavumba, kodwa zimbalwa izinto ezingenatyhefu. Namhlanje ndiza kukwazisai-hydroxyethyl cellulose, nto leyo exhaphake kakhulu kwizinto ezininzi zokuthambisa okanye eziyimfuneko zemihla ngemihla.
I-Hydroxyethyl Cellulose
Ikwaziwa njenge (HEC) yintsinga emhlophe okanye ekhaphukhaphu, engenavumba, engeyotyhefu okanye eqinileyo. Ngenxa yeempawu zayo ezintle zokuqina, ukumisa, ukusabalalisa, i-emulsifying, ukubambelela, ukwenza ifilimu, ukukhusela umswakama kunye nokubonelela nge-colloid yokukhusela, i-HEC isetyenziswe ngokubanzi kwiinkalo zonyango kunye nezimonyo.
Iimpawu zeMveliso
1. I-HEC iyancibilika emanzini atshisayo okanye kumanzi abandayo, ukushisa okuphezulu okanye ukubilisa ngaphandle kwemvula, ukuze ibe noluhlu olubanzi lwe-solubility kunye neempawu ze-viscosity, kunye ne-gelation engeyona i-thermal;
2. Ayiyiyo i-ionic kwaye inokuhamba kunye nezinye iipolymers ezinyibilikayo zamanzi, i-surfactants kunye neetyuwa kuluhlu olubanzi. Yinto egqwesileyo ye-colloidal thickener yezisombululo eziqulethe i-dielectrics ephezulu yoxinaniso;
3. Umthamo wokugcinwa kwamanzi uphindwe kabini kunalowo we-methyl cellulose, kwaye unolawulo olungcono lokuhamba;
4. Xa kuthelekiswa ne-methyl cellulose eyaziwayo kunye ne-hydroxypropyl methyl cellulose, ikhono lokusabalalisa i-HEC libi kakhulu, kodwa ikhono lokukhusela i-colloid linamandla.
RoleyeHECkwizinto zokuthambisa
Ubunzima be-molecular kwi-cosmetics, ubuninzi bezinto ezifana ne-synthetics yendalo kunye ne-artificial synthetics yahlukile, ngoko ke kuyimfuneko yokongeza i-solubilizer ukwenza zonke izithako zisebenze kakuhle. I-solubility kunye neempawu ze-viscosity ze-hydroxyethyl cellulose zidlala indima epheleleyo, kwaye zigcine uphawu olulungeleleneyo, ukwenzela ukuba lukwazi ukugcina imilo yokuqala yezinto zokuthambisa ngamaxesha okutshintshana okubandayo kunye nokutshisa. Ukongeza, ineempawu zokuthambisa kwaye ifumaneka ngokuqhelekileyo kwizithambiso kwiimveliso zokuthambisa. Ngokukodwa iimaski, iitoni, njl., phantse zonke zongezwa.
Umsebenziisiphumo
Iselulosi yeHydroxyethyl esetyenziswa kwizinto zokuthambisa ezifana ne-emollients, thickeners, njl. Kwaye ithathwa njengeNombolo ye-1 yemveliso yokhuseleko lokusingqongileyo yi-EWG.
