Hydroxypropyl Methyl Cellulose , ko HPMC , wani Semi-Synthetic cellulose ether ne wanda aka samo daga cellulose mai tsabta. Ana amfani dashi ko'ina azaman mai kauri, wakili mai riƙe ruwa, ɗaure, tsohon fim, stabilizer, da emulsifier a cikin kayan gini, samfuran kulawa na sirri, tsarin abinci, da ƙirar magunguna.
HPMC tana da ƙima saboda yana iya haɓaka iya aiki, sarrafa daidaito, da goyan bayan ingantaccen aiki a cikin ƙira da yawa. Halinsa na ƙarshe ya dogara sosai akan ingancin albarkatun ƙasa da kuma daidaitaccen tsarin masana'anta.
Yawan samarwa na HPMC gabaɗaya ya haɗa da matakai masu zuwa:
1. Zaɓin kayan albarkatun kasa da shirye-shirye.
2. Alkalization na cellulose.
