Imisebenzi ephambili ye-hydroxyethyl cellulose kwizinto zokuthambisa kunye neemveliso zokunakekelwa kwesikhumba zii-agent ezenza ifilimu, i-emulsion stabilizers, i-adhesives, kunye ne-hair conditioners.Umngcipheko ngu-1, okhuselekileyo kwaye unokusetyenziswa ngokuzithemba.Ngokuqhelekileyo, ayinayo impembelelo kubasetyhini abakhulelweyo.Iselulosi yeHydroxyethyl ayiyo comedogenic.I-Hydroxyethyl cellulose yiglu yokwenziwa kwepolymer esetyenziswa njengesithambiso solusu, ifilimu yangaphambili kunye ne-antioxidant kwizinto zokuthambisa.
Kukho izithako ezininzi kwizithambiso, kwaye wonke umntu akazi ukuba yintoni indima yezi zithako?
Indima ye-hydroxyethyl cellulose kwizinto zokuthambisa:
I-solubility kunye neempawu ze-viscosity ze-hydroxyethyl cellulose zidlala indima epheleleyo kwaye zigcine ukulingana, ukwenzela ukuba imilo yangaphambili ye-cosmetics inokugcinwa ngamaxesha okutshintshana okubandayo kunye nokutshisa.Ukongeza, ineempawu zokuthambisa kwaye ifumaneka ngokuqhelekileyo kwizithambiso kwiimveliso zokuthambisa.Ngokukodwa iimaski, iitoni, njl., phantse zonke zongezwa.
Ngaba izinto zokuthambisa zinokugcinwa efrijini?
Ezinye izinto zokuthambisa zinokugcinwa efrijini, njengezithambiso zolwelo, yaye ezinye izithambiso azifanelekanga ukuba zigcinwe efrijini, njengezithambiso zomgubo okanye izithambiso ezinamafutha.
Izithambiso zomgubo ziquka umgubo, iblush kunye nesithunzi samehlo.Xa ugcina ezi zinto zokuthambisa, gcina izinto zokuthambisa zomile, kuba ezi zithambiso zomgubo azinamanzi yaye zinokufunxa ukufuma kwisikhenkcisi, nto leyo eya kubangela ukuba izinto zokuthambisa ziwohloke.Gcina izinto zokuthambisa zomgubo ngamaxesha aqhelekileyo, kwaye uzigcine ngokuthe ngqo kwindawo epholileyo, eyomileyo nengena umoya.
Ukuba imveliso isekelwe kwi-oyile, inokuqina kwiqondo lokushisa eliphantsi kakhulu, okanye ibangele ukuba olu hlobo lwemveliso lube yi-viscous, ngoko ke akufanelekanga ukuyigcina efrijini xa igcinwe, nje ukuba igcinwe ubushushu begumbi.
I-Perfume inokugcinwa kwindawo yokushisa ephantsi, enokunyusa ubomi beshelufu.Ngokukodwa ehlotyeni, ukuyigcina efrijini kuya kwenza ukuba i-perfume ibe yinto epholileyo kwaye ikhululekile xa ifafazwa.
Ezinye izithambiso zenziwe ngezinto eziphilayo okanye ezigcinwe kwi-preservative-free, kwaye zigcinwe efrijini zinokwandisa ubomi beshelufu kwaye zigcine izithambiso zintsha.
Impembelelo ye-hydroxyethyl cellulose eluswini:
I-Hydroxyethyl cellulose ayinayo impembelelo eluswini.I-Hydroxyethyl cellulose isetyenziswa kwiimaski ezininzi zobuso, izicoci zobuso, kunye neeshampu, ikakhulu kuba i-hydroxyethyl cellulose inemisebenzi ye-thickener kunye ne-emulsifier.I-Hydroxyethyl cellulose yimveliso esekwe emanzini kunye neyokusingqongileyo.Ulusu alunabungozi.
I-Hydroxyethyl cellulose (HEC) yi-cellulose emhlophe okanye ekhaphukhaphu, engenavumba, engeyotyhefu okanye eqinile, elungiswa yi-etherification reaction ye-alkaline cellulose kunye ne-ethylene oxide (okanye i-chlorohydrin).I-Nonionic e-soluble cellulose ethers.Ekubeni i-HEC ineepropati ezintle zokuqina, ukumisa, ukusabalalisa, i-emulsifying, i-bonding, ifilimu-ifom, ukukhusela umswakama kunye nokubonelela nge-colloid ekhuselayo, isetyenziswe ngokubanzi kwi-petroleum ukuhlola, ukugubungela, ukwakhiwa, amayeza, ukutya, i-textile, i-papermaking kunye ne-polymerization. kunye neminye imimandla.
Kwizinto zokuthambisa, i-solubility kunye ne-viscosity properties ye-hydroxyethyl cellulose idlala indima epheleleyo, kwaye igcine impawu elinganayo, ukwenzela ukuba imilo yangaphambili yezithambiso inokugcinwa ngamaxesha okutshintshana okubandayo kunye nokutshisa.
Ukusebenza kwemveliso ye-Hydroxyethyl cellulose:
I-1.HEC iyancibilika emanzini atshisayo okanye kumanzi abandayo, kwaye ayigqithisi kwiqondo lokushisa eliphezulu okanye ukubilisa, ukwenzela ukuba inoluhlu olubanzi lwe-solubility kunye neempawu ze-viscosity, kunye ne-gelation engeyiyo i-thermal;
I-2.Ayiyo i-ionic kwaye inokuhlalisana kunye noluhlu olubanzi lwezinye iipolymers ezinyibilikayo zamanzi, i-surfactants, kunye neetyuwa.Yinto egqwesileyo ye-colloidal thickener yezisombululo eziqulethe i-dielectrics ephezulu yoxinaniso;
3. Umthamo wokugcina amanzi uphindwe kabini kunowo we-methyl cellulose, kwaye unolawulo olungcono lokuhamba.
