Esterified cellulose ethers of very low viscosity |
| abstract |
An esterified cellulose ether which comprises (i) aliphatic monovalent acyl groups or (ii) 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, or (iii) a combination of aliphatic monovalent acyl groups and groups of the formula —C(O)—R—COOA, and which has a) a viscosity of from 1.2 to 1.8 mPaos, measured as a 2.0 wt % solution of the esterified cellulose ether in 0.43 wt % aqueous NaOH at 20° C., or b) a viscosity of up to 5 mPa·s, measured as a 10 wt % solution of the esterified cellulose ether in acetone at 20° C., or c) a combination of the viscosities of a) and b), is useful for preparing solid dispersions comprising drugs. |
