Cooling Profile & Sensory Characteristics
WS-1 delivers a moderate, well-balanced cooling effect with a smooth onset. The cooling sensation builds gently, holds for several minutes, and fades without a harsh aftertaste. At recommended use levels it shows very low bitterness, making it easy to combine with sweeteners, acids and fruit flavors. It is thermally stable, surviving pasteurization, baking and other heat processes far better than menthol.
