Patent ID: 8481114

Claim:
A process for producing a water dispersible polymer composition comprising the steps of i) foaming a fluid composition comprising sodium lauryl sulfate surfactant, water, and maltodextrin to produce a foam; ii) adding the produced foam to water-soluble polymer particles selected from hydroxyl propyl methylcellulose or methylcellulose having a weight average molecular weight of at least 300,000; and iii) drying the mixture to form encrusted particles, whereby the foam collapses during the contacting and/or drying step and the water-soluble polymer particles having a weight average molecular weight of at least 300,000 are encrusted with the surfactant and the maltodextrin, and wherein the process is conducted in a high shear mixing device, a low shear mixing device, a fluidized bed granulator, a roller compactor or a spray dryer.
