WS-3 Cooling Agent (Koolada) 10%
WS-3 is a high-purity cooling agent that delivers a clean, refreshing cooling sensation without the flavour, aroma, or bitterness associated with menthol. Widely used across food, beverage and confectionery applications, WS-3 provides a smooth and long-lasting cooling effect primarily perceived in the mouth, palate, and throat.
Unlike menthol, WS-3 does not impart a minty taste, allowing formulators to enhance freshness while maintaining the integrity of the intended flavour profile. Its moderate cooling intensity and excellent stability make it one of the most versatile and widely used cooling agents in the flavour and fragrance industry.
Key Features:
- Clean cooling sensation with no mint flavour or odour
- Long-lasting cooling effect
- Excellent flavour compatibility
- High thermal and pH stability
- Suitable for food, beverage, confectionery and oral care
- Effective at low inclusion levels
The WS-series cooling agents are coolants originally developed to provide a cooling sensation without the strong mint flavour and aroma of menthol. The main differences between WS-3, WS-5, WS-12, and WS-23 are their cooling intensity, onset speed, duration, and where the cooling is perceived in the mouth/throat.
