摘要：
An aqueous composition comprising at least 10 weight percent of a dispersed esterified cellulose ether, based on the total weight of the aqueous composition, wherein the esterified cellulose ether comprises (i) groups of the formula -C(O) - R - COOH or (ii) a combination of aliphatic monovalent acyl groups and groups of the formula -C(O) - R - COOH, R being a divalent aliphatic or aromatic hydrocarbon group, and at least a part of the groups -C(O) - R - COOH are neutralized with an ammonium salt of carbonic acid, formic acid or acetic acid, and wherein d90 of the dispersed esterified cellulose ether particles is up to 10 micro - meters, d90 being the diameter where 90 mass percent of the particles have a smaller equivalent diameter and the other 10 mass percent have a larger equivalent diameter, is useful for preparing coating dosage forms including tablets, capsules and others, or for the formation of capsules shells.
