hydroxypropyl methyl cellulose

Hydroxypropyl methyl cellulose (HPMC) bụ eriri polymer eke site na usoro nhazi kemịkalụ na nkwadebe nke cellulose ether na-abụghị ionic.
Usoro DB HPMC bụ ngwaahịa cellulose ether emezigharịrị nke na-agbaze na mmiri ma mepụta ya nke ọma maka imeziwanye arụmọrụ nke ngwa agha akọrọ mgbe emechara ọgwụgwọ elu.
