Ni ibihe byiciro bitandukanye bya HPMC?

HPMC, cyangwa hydroxypropyl methylcellulose, ni ubwoko bwa selile ikomoka kuri selile ikunze gukoreshwa nkigikoresho cyo kubyimba, emulisiferi, na stabilisateur mubicuruzwa bitandukanye. Ni ifu yera, idafite impumuro nziza, uburyohe butagira imbaraga zishonga mumazi akonje kandi ntashonga mumazi ashyushye.

HPMC iraboneka mubyiciro bitandukanye, buri kimwe gifite imiterere yihariye hamwe nibisabwa. Amanota ya HPMC ashingiye ku rwego rwo gusimbuza (DS) y'amatsinda ya hydroxypropyl, akaba ari igipimo cy'umubare w'amatsinda ya hydroxypropyl kuri anhydroglucose. Iyo hejuru ya DS, niko amatsinda ya hydroxypropyl arahari kandi hydrophilique HPMC ni.

Amanota ya HPMC agabanijwemo ibyiciro bitatu byingenzi: DS yo hasi, DS yo hagati, na DS ndende.

Hasi DS HPMC ikoreshwa mubisanzwe aho bifuza ubukonje buke nimbaraga nke za gel. Uru rwego rukunze gukoreshwa mubiribwa n'ibinyobwa, nka ice cream, isosi, na gravies. Irakoreshwa kandi mubikorwa bya farumasi, nkibinini na capsules.

Hagati ya DS HPMC ikoreshwa mubisabwa aho byifuzwa cyane hamwe na gel imbaraga. Uru rwego rukunze gukoreshwa mubiribwa n'ibinyobwa, nka jama na jellies, ndetse no mubikoresho bya farumasi, nk'amavuta na cream.

DS DS HPMC ikoreshwa mubisabwa aho bifuza cyane viscosity na gel imbaraga. Uru rwego rukunze gukoreshwa mubiribwa n'ibinyobwa, nka foromaje na yogurt, ndetse no mubikoresho bya farumasi, nka suppository na pessaries.

Usibye ibyiciro bitatu byingenzi bya HPMC, hariho ibyiciro byinshi. Ibi byiciro bishingiye ku rwego rwo gusimbuza, ingano yingingo, nubwoko bwa hydroxypropyl.

Urwego rwo gusimbuza ibyiciro rushingiye ku rwego rwo gusimbuza amatsinda ya hydroxypropyl. Ibi byiciro ni bike DS (0.5-1.5), DS yo hagati (1.5-2.5), na DS ndende (2.5-3.5).

Ingano yubunini bwibice bishingiye ku bunini bwibice. Ibi byiciro ni byiza (munsi ya microne 10), hagati (microne 10-20), kandi bitoroshye (microne zirenga 20).

Ubwoko bwa hydroxypropyl matsinda matsinda ashingiye kubwoko bwa hydroxypropyl groupe igaragara muri HPMC. Ibi byiciro ni hydroxypropyl methylcellulose (HPMC), hydroxypropyl ethylcellulose (HPEC), na hydroxypropyl selile (HPC).

HPMC ni ibintu byinshi kandi bikoreshwa cyane mubicuruzwa bitandukanye. Ibyiciro bitandukanye bya HPMC bishingiye ku rwego rwo gusimbuza, ingano y'ibice, n'ubwoko bwa hydroxypropyl, kandi buri cyiciro gifite imiterere yihariye n'ibisabwa.
