Calcium Sulfate Dihydrate

COMPACTROL® is a specially processed Calcium Sulfate Dihydrate for use as a filler in tablets made by direct compression or for use as a binder in wet granulation.

COMPACTROL® is an inorganic material that is mainly used in wet granulations to improve the binding properties, especially in classic granulations that use starch or cellulose as a base. It has high calcium content and can be used in dietary supplements as a source of calcium.


  • Improved binding in wet granulation formulations
  • Filler and diluent functions in direct compression blends
  • High bulk density for capsule filling
  • Optimal particle size for pharmaceutical applications
