The invention relates to a carboxylate ester of polysaccharide characterized 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.

A polymer mixture in solid or aqueous form includes a content of from 5 to 95% by weight of a first polymer and a content of from 5 to 95% by weight of a second polymer. The first polymer is a water-soluble or water-dispersible polymer having a weight-average molecular weight of 1000 to 20 000 g/mol. The second polymer is a water-soluble or water-dispersible polymer having a weight-average molecular weight of 1000 to 50 000 g/mol. The polymer mixture can inhibit precipitation and sedimentation of calcium salts and magnesium salts in water-bearing systems.

A continuous method for surface treatment of metal strips applies a finish coat having a thickness of not more than 3 &#x3bc;m, the apparatus employed for application being equipped with at least one IR sensor which faces a coated side of the strip, operates in reflection geometry, and serves to measure the coat thickness of the finish coat, with the strip running.
