Flowable grades of calcium stearate have coarser particle sizes in order to reduce dusting and improve bulk handling properties. This study shows that in many cases, some flowable grades of calcium stearate will disperse as homogeneously as a powdered grade and under these conditions the two grades of calcium stearate could be used interchangeably. Under some conditions, however, some flowable grades of calcium stearate will not completely disperse and so the use of flowable grades of calcium stearate must be considered on a case by case basis.
