Cooling Profile & Sensory Characteristics
WS-3 offers a strong, classic cooling effect with a relatively fast onset and a minty character that blends seamlessly with peppermint and spearmint flavors. The cooling sensation is clean and pleasant at recommended levels, with only mild bitterness at high dosages. The effect lasts several minutes — noticeably longer than menthol — and does not flash off during production.
