“…corn and rice starch) are widely used as glidants, tablet disintegrants and binders, and capsule diluents (Marchessault et al, 2006). Numerous cellulose derivatives such as methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, and hydroxylpropylmethyl cellulose, which often possess specific respond or even better physicochemical properties than cellulose have been applied in pharmaceutical applications (Francis, Piredda, & Winnik, 2006;Jain et al, 2014;Li & Mei, 2006;Marchessault et al, 2006). For example, phthalated hydroxypropylmethyl cellulose has excellent pH-dependent solubility, namely, stability in acidic conditions (at stomach) but soluble in mildly acidic to slightly alkaline solution and, therefore, has been developed for controlled intestinal targeting drug release systems (Kim, Park, Cheong, & Kim, 2003;Xu, Gao, Xu, Wu, & Sun, 2009).…”
