Features & Benefits

Product Information
  • Film coating with hydroxypropylmethylcellulose is a well known, established and effective technique. These coatings are now in widespread use throughout the world. BonuCel® does not interact with drugs, and it has a superior stability and non-ionic character, so it is also effective as a binder. Due to its more stable characteristics, BonuCel® can also be used instead of gelatine for cellulose capsule manufacturing.
  • The high-viscosity BonuCel®-types are exclusively designed for a hydrophilic matrix agent. This is the easiest sustained release technology for oral dosage forms, consisting essentially of a drug and a watersoluble high viscous polymer.
  • BonuCel® consists of highly purified cellulose fibers based on natural raw materials. Mainly renewable wood fibers are used as the primary raw material for the production of cellulose ethers.
