AquaPolish® SR enables a sustained release of active ingredients and creates a strong and insoluble film coating with good adhesion, through which the active ingredient diffuses. The use of high quality, insoluble cellulose ethers or Ammonio Methacrylate Copolymer (Type A, Type B) in combination with soluble cellulose ethers, plasticizing and coloring additives, guarantees film coatings that are always reproducible. By varying the type and amount of the cellulose ethers used, a wide range of release profiles can be achieved.

Clear, white and colored preparations can be tailor-made according to customer requirements.
