As a menthol derivative, WS-12 exhibits significantly higher potency than menthol and provides a stronger initial cooling effect along with more sustained duration compared to WS-3, WS-5, and WS-23 . Unlike menthol, WS-12 produces minimal odor and no irritating pungency, offering a clean, refreshing cooling sensation that enhances products without altering their intended flavor profiles .\n\nCooling Profile\n\nThe cooling agent offers a distinctive sensory experience with the following characteristics:\n\nSuperior initial cooling impact: Provides strong, immediate cooling that activates the palate instantly, with higher potency than menthol or other WS-series agents \n\nExtended duration: Cooling sensation persists for 10–30 minutes, significantly longer than menthol \n\nTargeted cooling areas: Focuses primarily on the throat area, producing a lasting fresh finish \n\nClean, non-pungent profile: Minimal odor with mild menthol-like notes; no bitterness, burning, or irritating effects \n\nHeat stability: Maintains cooling effectiveness at temperatures up to 200°C, suitable for baking and heat-processed applications \n\nKey Features\n\nHigh cooling potency: Low dosage required—typically 15–100 mg/kg for strong effect \n\nExcellent thermal stability: Retains cooling properties under high-temperature processing (up to 200°C) \n\nSynergistic compatibility: Works well with other cooling agents and flavors for enhanced profiles; used with WS-3, WS-5, WS-23 in combinations \n\nNon-irritating: Gentle on skin and mucous membranes, suitable for sensitive applications \n\nRegulatory compliant: Listed under FEMA 4681 and JECFA 2079; approved as a food additive
