What's New?

An exciting new Troche Base to use in your troches and lozenges!

Xenex Labs Troche Base - Non-bitter, Sugar-free


Made with only 5 ingredients, the XenCare Troche Base is a sugar-free, non-bitter base that will ultimately provide a better experience for the patient. Its simplicity makes it very easy to work with as it is fully miscible with water, and melts at 43C (109.4F). And because it already has a natural sweetener, your formula will not require additional sweetening ingredients.



  • Polyethylene Glycol as the main base ingredient
  • Anti-caking adsorbant makes your ingredients incorporate easily.
  • Bitter-bloc™ masks unpleasant flavors that come from certain APIs
  • Xanthan gum  a natural ingredient that binds the ingredients elegantly.
  • Stevia leaf extract naturally sweetens the base to provide a better experience for the patient.
