More Information
Summary:In a process for producing a particulate polysaccharide derivative by dry-grinding a moist polysaccharide derivative, one or more of the properties selected from median diameter, median length, bulk density and dissolution rate is controlled by controlling the temperature of the polysaccharide derivative prior to dry-grinding. Advantageously one or more of the properties selected from median diameter, median length, bulk density and dissolution rate of the particles after dry-grinding is adjusted to a first value by a first temperature of the polysaccharide derivative prior to dry-grinding and is adjusted to a second value by a second temperature.
