Abstract:
1. A modified polysaccharide ether having a weight-averaged molecular weight of 40,000-500,000 g/mol, a zero-shear viscosity of more than 10 Pa·s, and a pseudo-plasticity of more than 20, the modified polysaccharide ether obtainable by reaction-of a polysaccharide ether (s) selected from the group consisting of hydroxypropyl methylcellulose (HPMC), hydroxyethyl methylcellulose (HEMC), methylcellulose, cellulose ethers with methyl and/or ethyl and/or propyl groups, and mixtures thereof with at least one cholesterol or cholesterol derivative, wherein the degree of substitution of cholesterol or cholesterol derivative groups is 0.001-0.01 per anhydroglucose unit and wherein the modified polysaccharide ether forms fringe micelles in aqueous solution.
