Typically, modified starches include esters, such as the acetate and the half-esters of dicarboxylic acids/anhydrides, particularly the alkenylsuccinic acids/anhydrides; ethers, such as the hydroxyethyl- and hydroxypropyl starches; starches oxidized with hypochlorite; starches reacted with cross-linking agents such as phosphorus oxychloride, epichlorohydrin, hydrophobic cationic epoxides, and phos
