摘要：
An aqueous composition useful for producing capsules shells comprises a) at least one 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 and b) from 0.05 to 20 percent of at least one salt of a fatty acid based on the weight of the dispersed esterified cellulose ether wherein the median particle size d50 of the dispersed esterified cellulose ether particles is up to 7 micrometers such median particle size (d50) being the size at which 50 mass percent of the particles have a smaller equivalent diameter and 50 mass percent have a larger equivalent diameter.
