Abstract: The invention relates to a carboxylate ester of polysaccharide characterised in that it possesses ester bonds with trimellitic anhydride and is soluble in water. The polysaccharide is esterified with trimellitic anhydride and the degree of substitution of the polysaccharide lies in the range of from 0.5 to 3. The invention further relates to methods for the manufacture of these polysaccharides esters in organic solvents, in water or in an extruder or a kneader and to their use in fabric and home care formulations.

Abstract: Described herein is a washing- and cleaning-active multilayer film including at least one layer including a polymer composition obtainable by free-radical polymerization of a monomer composition including at least one α,β-ethylenically unsaturated carboxylic acid or a salt or an anhydride thereof, where the free-radical polymerization is effected in the presence of at least one polyether component. Also described herein is a process for producing the multilayer film, methods of using the multilayer film and a sheath or coating for a washing or cleaning composition portion including the multilayer film.
