Abstract
The present invention relates to a water-soluble associative cellulose ether having a DP viscosity from 250 to 20,000 mPa·s, measured at a concentration of 1% by weight, and a molecular substitution, MS, from 0.0001 to 0.005 of a hydrophobic substituent containing an unsubstituted or substituted hydrocarbon group of 8-24 carbon atoms. The cellulose ether has a good thickening effect and advantageous application properties at low contents and can be used in an aqueous decorative paint composition, an aqueous paper coating composition, an aqueous organic filler composition, an aqueous cement slurry, an aqueous detergent composition or an aqueous personal care formulation.
