Hiki ke hoʻomaikaʻi ʻia nā huahana QualiCell HPMC e nā waiwai aʻe ma Pharmaceutical Excipient:
· Ke hoʻoheheʻe ʻia i ka wai a hoʻoheheʻe ʻia ma o ka solvent, hana ʻo HPMC i ke kiʻi ʻoniʻoni me ka ikaika tensile kiʻekiʻe.
· Hoʻonui i ka mana paʻa .
·Hydrophilic matrix i hoʻohana pū ʻia me HPMC hydrates e hana i kahi papa gel, kaohi ʻana i ke ʻano hoʻokuʻu lāʻau.
