Focus on Cellulose ethers

Fa'apitoa mo le fa'aoga i aso uma: maualuga, maualuga vave-hydroxypropyl methylcellulose!

O le vai malulu vave hydroxypropyl methylcellulose (HPMC) Igoa Igilisi: Hydroxypropyl methyl cellulose (HPMC) Fa'aigoa masani: fa'amalo vave, faʻamaumau faʻamau, faʻamautu faʻamaʻi, faʻasalalau faʻasalalau, faʻapipiʻi faʻamaʻi, cellulose vave.

Vaega autu ma le fausaga o vailaau: ether cellulose le ionic e faia mai le cellulose polymer masani.

Folasaga o oloa: Hydroxypropyl methylcellulose (HPMC) o se polymer non-ionic, o se ether cellulose e le ionic e faia mai le cellulose meafaitino masani. O le oloa o se paʻu e leai se manogi, leai se tofo, e le oona, e mafai ona faʻamavaeina i le vai malulu e fausia ai se vaifofo manino manino ma le mafiafia, faʻapipiʻi, faʻasalalau, emulsifying, ata tifaga, faʻagata, adsorbing, gelling, ma luga. toaga , Susū taofi ma puipuiga colloid meatotino.

O aso ta'itasi vaila'au vasega vave hydroxypropyl methylcellulose HPMC e masani ona fa'aaogaina i vaila'au i'e, mea fa'amamā vaila'au i aso ta'itasi, mea teuteu ma isi fanua; e pei o le shampoo, fufuluina o le tino, faʻamamā mata, lotion, kulimi, gel, toner, tausiga o le paʻu Faʻamaʻi lauulu, mea faʻapipiʻi, fulunifo, faua, vai meataalo, ma isi.

O uiga o oloa o vailaʻau faʻasolosolo i aso taʻitasi hydroxypropyl methylcellulose HPMC:

1. Mea masani mataʻutia, maualalo le ita, faʻatinoga malie, saogalemu ma le puipuiga o le siosiomaga;

2. Suavai solubility ma mafiafia meatotino: e mafai ona soloia i le vai malulu, solo i nisi solvents organic ma le paluga o vai ma solvents organic;

3. Faʻafefete ma viscosity-faʻateleina: o se faʻaopoopoga laʻititi i le faʻamavaeina o le a fausia ai se fofo viscous manino, maualuga le manino, faʻamautu le faʻatinoga, suiga o le solubility ma le viscosity, o le maualalo o le viscosity, o le tele o le solubility; fa'aleleia lelei le mautu o le tafe o le faiga;

4. Tete'e masima: HPMC o se polymer non-ionic, e matua mautu i vaifofo vai o masima uʻamea po electrolytes organic;

5. Fa'asagaga i luga: o le vaifofo vai o le oloa o lo'o i ai le gaioiga i luga, ma ei ai galuega ma meatotino o le emulsification, colloid puipuia ma le mautu; o le vevesi i luga o le: 2% vaifofo vai o 42 ~ 56dyn / cm;

6. Faʻamautu PH: o le viscosity o le vaifofo vai e mautu i totonu ole laina ole PH3.0-11.0;

7. Vai-taofia aafiaga: o le meatotino hydrophilic o le HPMC e mafai ona faaopoopo i slurry, faapipii ma pasty oloa e faatumauina ai le maualuga o le vai-taofia aafiaga;

8. Gelation Thermal: Pe a vevela le vaifofo vai i se vevela faapitoa, e avea opaque seia oo ina fausia ai se tulaga flocculation (poly), ina ia leiloa le vaifofo lona viscosity. Ae a maeʻa le malulu, o le a toe liliu i le tulaga muamua fofo. O le vevela o loʻo tupu ai le faʻaaliga o le gel e faʻalagolago i le ituaiga o oloa, le faʻaogaina o le fofo ma le fua faʻavevela;

9. O isi uiga: sili ona lelei le faia o ata tifaga, faʻapea foʻi ma le lautele o le enzyme resistance, dispersibility ma le faʻatasi;

10. O le viscosity amata taimi o aso uma vasega kemikolo hydroxypropyl methylcellulose i le vai paipa i le vevela masani e 3 minute, ma o le viscosity amata taimi i le vai mama o le a telegese, e uiga i 30 minute, ina ia lava galuega Taimi, faigofie e pulea viscosity. , faigofie ona fa'aoga.
