pH:
pH na maganin yana tasiri danko na HPMC ta hanyar tasirinsa akan solubility na polymer da daidaituwa. HPMC shine mafi narkewa kuma yana nuna matsakaicin danko a cikin ɗan acidic zuwa tsaka tsaki pH jeri. Bambance-bambance daga wannan kewayon pH na iya haifar da raguwar solubility da danko saboda canje-canje a cikin daidaituwar polymer da hulɗa tare da ƙwayoyin ƙarfi. Saboda haka, kiyaye mafi kyawun yanayin pH yana da mahimmanci don haɓaka danko na HPMC a cikin bayani.

Additives:
