HEC mo mea teuteu ma le tausiga o le tagata lava ia

Hydroxyethyl cellulose HEC o se vaega taua i mea teuteu ma le tausiga o le tagata lava ia. Le solubility ma le viscosity meatotino o le hydroxyethyl cellulose HEC faia se sao atoatoa i le tausia o le paleni, ina ia mafai ona faatumauina le foliga muamua o mea teuteu e oo lava i vaitau vevela ma malulu. E le gata i lea, o loʻo i ai uiga faʻafefete ma e masani i le faʻafefeteina o mea teuteu. Aemaise lava ufimata mata, toner ma isi e toetoe lava a faaopoopo.

Cosmetics, e pei o se ituaiga o vailaʻau faʻafesoʻotaʻi tuusaʻo i luga o le paʻu, e faʻapitoa tagata faʻapitoa i le tuʻufaʻatasia ma le saogalemu o latou mea e aofia ai i le faʻaopoopoga i la latou matagofie ma le tausiga o le paʻu.

O le ais hydroxyethyl celluloseHEC?

HECHydroxyethyl cellulose ose pa'epa'e po'o samasama samasama, e leai se tofo, e le o'ona po'o fibrous solid. I falegaosimea ma falesuesue fa'asologa, cellulose ma le ethylene oxide (po'o le chloroethanol) e masani lava ona fa'apipi'iina e ala i le etherification reaction.

Meatotino ma galuega tauave aHEC:

HEC ei ai meatotino lelei o le faateleina o le viscosity, tulaga tutusa, emulsifying solution, faʻapipiʻi, faʻapea foʻi ma le faʻaitiitia o le susu ma le tuʻuina atu o colloid puipuia.

Matafaioi o HEC i mea teuteu

o le cosmetic o loʻo i totonu o ituaiga uma o mea faʻalenatura poʻo mea faʻapipiʻi vailaʻau faʻalavelave faʻalavelave faʻapitoa, ma mea faʻaletino ma vailaʻau i le va o paaga, i le faagasologa o le faia o mea teuteu e manaʻomia ona faʻaopoopo leHEC as emulsifier, adhesives e mafai ona faia ituaiga o mea e oʻo atu i se aafiaga palasitika faifai pea. I le fa'aogaina, e mafai fo'i ona fetu'una'i mea teuteu i ituaiga pa'u 'ese'ese ma le vevela ma le susū o le si'osi'omaga. Ina ia faʻateleina le faʻaogaina o maketi ma le faʻaogaina o le faʻaaogaina o tagata. O mea fa'asusu oHEChydroxyethyl cellulose e iai fo'i se sao taua i le fa'asusuina o le pa'u.

Water-soluble polymer compound fa'aaogaina i mea teuteu

E iai vaega fa'anatura ma synthetic. Fa'alenatura vai-soluble polymer compounds o: masoa, laau gum, gelatin manu, ma isi, ae o le tulaga lelei e le mautu, vaivai i le tau, siosiomaga fa'afanua, fa'atapula'a fua, ma fa'aletonu i siama, limu ma metamorphic aafiaga.HECHydroxyethyl cellulose tu'ufa'atasiga o fa'aputuga polymer solu vai: polyvinyl alcohol, poly (ethylene) Pyrrolidone, mautu, maualalo le ita i le paʻu, tau maualalo, o lea nai lo le vai-soluble polymer compounds avea ma punavai autu o colloid mata. Ua vaevaeina i semi-synthetic ma synthetic vai-soluble polymer compounds. Semi-synthetic vai-soluble polymer compounds e masani ona faʻaaogaina: methyl cellulose, ethyl cellulose, carboxymethyl fiber,Vitamini sodium,HEChydroxyethyl cellulose, guar gum ma a latou mea e maua mai ai. Fa'asologa o fa'aputuga polymer solu vai e masani ona fa'aogaina: polyvinyl alcohol, polyvinylpyrrolidone, acrylic acid polymer. O loʻo faʻaaogaina i mea teuteu e pei o mea faʻapipiʻi, mafiafia, faʻapipiʻi ata, emulsifying stabilizers.
