摘要
A composition comprising a) an esterified cellulose ether comprising aliphatic monovalent acyl groups and groups of the formula —C(O)—R—COOH, R being a divalent hydrocarbon group, wherein I) the degree of neutralization of the groups —C(O)—R—COOH is not more than 0.4 and II) the total degree of ester substitution is from 0.03 to 0.70, and b) a cellulose ether having a viscosity of from 1.2 to 200 mPa s, measured as a 2 weight-% aqueous solution at 20° C., gels at increased temperature and displays reduced syneresis when further increasing the temperature of the gel.
