Kwizinto zokuthambisa, zininzi iikhemikhali ezingenambala nezingenavumba, kodwa zimbalwa izinto ezingenatyhefu.Namhlanje, ndiya kukwazisa kuwe, i-hydroxyethyl cellulose, exhaphake kakhulu kwizinto ezininzi zokuthambisa okanye iimfuno zemihla ngemihla.
Iselulosi yeHydroxyethyl【Iselulosi yeHydroxyethyl】
Ikwaziwa njenge (HEC) yintlupheko emhlophe okanye emthubi, engenavumba, engenatyhefu okanye eqinileyo.Ngenxa yokuba i-HEC ineempawu ezintle zokuqina, ukumisa, ukusabalalisa, i-emulsifying, i-bonding, ifilimu-ifom, ukukhusela umswakama kunye nokubonelela nge-colloid yokukhusela, isetyenziswe ngokubanzi kwizicelo zonyango kunye nezimonyo.
Iimpawu zeMveliso
I-1.HEC iyancibilika kumanzi ashushu okanye abandayo, kwaye ayigqithisi kwiqondo lokushisa eliphezulu okanye ukubilisa, okwenza kube neentlobo ezininzi ze-solubility kunye neempawu ze-viscosity, kunye ne-gelation engeyiyo i-thermal;
2. I-non-ionic ngokwayo inokuhlalisana kunye nolunye uluhlu olubanzi lwezinye iipolymers ezinamanzi, i-surfactants kunye neetyuwa, kwaye i-colloidal thickener egqwesileyo equlethe izisombululo ze-dielectric eziphezulu;
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 i-colloid yokukhusela inamandla amakhulu.
indima kwizinto zokuthambisa
Ubunzima be-molecular of cosmetics, ubuninzi bezinto ezixutywayo zendalo, i-artificial compounds kunye nezinye izinto ziyahluka, ngoko ke kuyimfuneko yokongeza i-agent enyibilikayo ukwenza zonke izithako zidlale indima engcono kakhulu.I-solubility kunye neempawu ze-viscosity ze-hydroxyethyl cellulose zidlala indima epheleleyo, kwaye zigcine ukulingana, ukwenzela ukuba imilo yasekuqaleni yezithambiso inokugcinwa kwixesha elitshintshisayo lokubanda kunye nokushisa.Ukongeza, ineempawu zokuthambisa kwaye ixhaphakile kwizithambiso zeemveliso ezithambisayo.Ngokukodwa, iimaski, iitoni, njl., phantse zonke zongezwa.
imiphumela
Iselulosi yeHydroxyethyl esetyenziswa kwizithambiso ngokusisiseko ayinayo ityhefu xa usebenzisa izithambisi, izityebi, njl njl. Kwaye ithathwa njengeNombolo 1 yemveliso yokhuseleko lokusingqongileyo yi-EWG.
