摘要 |
Capsule shells and coatings can be prepared from an aqueous composition comprising a) at least 20 percent, based on the total weight of the aqueous composition, of a dispersed esterified cellulose ether comprising (i) groups of the formula -C(O) - R - COOA or (ii) a combination of aliphatic monovalent acyl groups and groups of the formula -C(O) - R - COOA, wherein R is a divalent aliphatic or aromatic hydrocarbon group and A is hydrogen or a cation, b) from 0.05 to 20 percent of a salt of a fatty acid, based on the weight of the dispersed esterified cellulose ether, and c) from 0.01 to 10 percent of an anionic surfactant comprising a sulfate or sulfonate group, based on the weight of the dispersed esterified cellulose ether. |
