800 Series
CBD/THC Flavor Masks

Enormous opportunity, if the flavor’s right

The CBD/THC opportunity is enormous for food, beverage, and nutritional brands. The problem? Its natural flavor is challenging, and there’s no one-size-fits-all fix. That’s why ClearMask gives CBD/THC product developers a range of dedicated solutions to 

  • maximize R&D flexibility and 

  • achieve the flavor your consumers want.

CBD/THC’s earthiness has three main components that the ClearMask range can neutralize, reduce, or rebalance to optimize product flavor. Series 800 formulas address combinations of these three components:

  1. Upfront bitter notes

  2. Lingering acrid bitterness

  3. The after "burn" (reminiscent of alcohol)

801  complete CBD solution

802  complete THC solution

803  enhances sweetness and amplifies other 800 masks when combined

804  best for beverages and other liquid applications

805  combines with other 800 masks to amplify effects; often used with 803

806  best in applications with a high level of sweetening, such as gummies

807  works in tandem with 806 in sweet applications

808  best for applications with delicate flavors

CBD/THC masking in action 

  • ClearMask does not impact CBD efficacy

  • ClearMask does not change CBD’s scent (generally thought to be pleasant)

  • Powder is water soluble

  • Can be declared as Natural Flavors
