  • Patent number: 4816298
    Abstract: A method of making a cold water dispersible granular composition comprising a plasticizer and thermally moldable polymer, for example hydroxypropyl methylcellulose, hydroxypropyl cellulose, carboxymethylcellulose, or hydroxy ethylcellulose. The method comprises, extruding the composition at elevated temperatures to form an extruded material and grinding the extruded material to form a granular product. The granules are very dispersible in cold water and when added to cold water, the solution can be used in coating operations, such as to coat pharmaceuticals, foods and food supplements to protect, color, harden, make foods more palatable or mask the taste of solid dosage forms.
