HPMC gel

Hydroxypropyl methylcellulose (HPMC) ni ubwoko bwa selile ya ether ikoreshwa muburyo butandukanye, harimo nka gelline, umubyimba, emulisiferi, stabilisateur, hamwe nu guhagarika akazi.Ni polymer yamashanyarazi ikomoka kuri selile, kandi ikoreshwa mubiribwa, imiti, no kwisiga.HPMC nayo ikoreshwa mugukora geles, ni sisitemu ya kimwe cya kabiri igizwe n'amazi yatatanye muri matrix ikomeye.Gele ya HPMC ikoreshwa muburyo butandukanye, harimo gutanga ibiyobyabwenge, kwisiga, nibiribwa.

HP ya HPMC ikorwa mugihe HPMC yashonga mumashanyarazi, nkamazi.Mugihe igisubizo gikonje, molekile ya HPMC ikora umuyoboro ufata umutego, ugakora gel.Ibiranga gel biterwa nubunini bwa HPMC, ubwoko bwa solvent, nubushyuhe.Gels ikozwe muri HPMC mubisanzwe iragaragara kandi ifite jelly isa neza.

HPMC geles irashobora gukoreshwa mubikorwa bitandukanye.Mu nganda zimiti, geles ya HPMC ikoreshwa mugutanga imiti mumubiri.Gele irashobora gutegurwa kugirango irekure imiti mugihe runaka, itume imiti ihoraho.Gele ya HPMC ikoreshwa no kwisiga, nk'amavuta yo kwisiga hamwe na cream, kugirango itange neza.Mu bicuruzwa byibiribwa, geles ya HPMC ikoreshwa nkibibyimbye na stabilisateur.

Geli ya HPMC ifite ibyiza byinshi kurenza izindi miti.Ntabwo ari uburozi, ntiburakaza, kandi burashobora kwangirika.Biroroshye kandi gukoresha kandi birashobora gutegurwa kugirango uhuze ibyifuzo byihariye.HP ya HPMC nayo irahagaze hejuru yubushyuhe bwinshi nurwego rwa pH.

Nubwo ibyo byiza, hari ibibi byo gukoresha geles ya HPMC.Birahenze cyane kuruta ibindi bintu byogukoresha, kandi birashobora kugorana gushonga mumashanyarazi amwe.Byongeye kandi, geles ya HPMC ntabwo ikomeye nkizindi mikorere ya gelling, kandi irashobora guhura na syneresis (gutandukanya gele mubice byamazi kandi bikomeye).

Muri rusange, geles ya HPMC nigikoresho cyingirakamaro kubikorwa bitandukanye.Ntabwo ari uburozi, ntibitera uburakari, kandi burashobora kwangirika, kandi burashobora gutegurwa kugirango buhuze ibikenewe byihariye.Nyamara, zihenze kuruta izindi miti ya gelling, kandi birashobora kugorana gushonga mumashanyarazi amwe.Byongeye kandi, ntabwo zikomeye nkizindi mikorere ya gelling, kandi zirashobora guhura na syneresis.
