HPMC, cyangwa Hydroxypropyl Methylcellulose, ntabwo igaragara muburyo bukomeye bw'ijambo. Surfactants ni molekile zifite hydrophilique (zikunda amazi) hamwe na hydrophobique (yanga amazi), kandi zikoreshwa mukugabanya ubukana bwubuso hagati yamazi abiri adasobanutse cyangwa hagati yamazi nigikomeye. Surfactants ikoreshwa muburyo butandukanye bwinganda, zirimo ibicuruzwa byogusukura, ibicuruzwa byita kumuntu, hamwe n’imiti, nibindi.

Ku rundi ruhande, HPMC ni polymer ishingiye kuri selile ikoreshwa mu bikorwa bitandukanye, birimo imiti, ibiryo, n’ibicuruzwa byita ku muntu, n'ibindi. HPMC ikorwa no guhindura imiti ya selile, ni polymer karemano iboneka mubihingwa. By'umwihariko, HPMC ikorwa mugusimbuza amwe mumatsinda ya hydroxyl muri selile hamwe na methyl cyangwa hydroxypropyl. Polimeri yavuyemo irashobora gushonga amazi kandi irashobora gukoreshwa nkibyimbye, binder, emulifier, na stabilisateur, mubindi bikorwa.

Nubwo atari surfactant, HPMC irashobora kwerekana imitungo isa na surfactant mubintu bimwe na bimwe. Kurugero, HPMC irashobora gukoreshwa muguhagarika emulisiyo, nuruvange rwamazi abiri adasobanutse, mugukora urwego rukingira ibitonyanga byamazi mumazi yandi. Uru rupapuro rushobora kubuza ibitonyanga guhuriza hamwe no gutandukana nibindi bivanze. Muri ubu buryo, HPMC irashobora gukora nka emulifier, ni ubwoko bwa surfactant.

Byongeye kandi, HPMC irashobora gukoreshwa kugirango igabanye ubuso bw’amazi, akaba ari umutungo wa surfactants. Kurugero, HPMC irashobora gukoreshwa nkigifuniko hejuru yubutaka kugirango irusheho kuba hydrophilique, ishobora kongera imiterere yabyo. Muri ubu buryo, HPMC irashobora kugabanya ubukana bwamazi hejuru yubuso, bushobora kunoza imiterere yamazi cyangwa ibinini hejuru.

Muri rusange, mugihe HPMC itari surfactant muburyo bukomeye bwijambo, irashobora kwerekana ibintu bisa nkibintu mubisabwa bimwe. HPMC ni polymer itandukanye ishobora gukoreshwa mubikorwa bitandukanye, kandi imitungo yihariye ituma iba ingirakamaro mubintu byinshi.
