Application & Uses
- WS-5 is widely used across diverse product categories, including oral care items (such as toothpaste and mouthwash), cosmetics (creams and lotions), food and beverages, pharmaceuticals, and personal care products (shampoos and conditioners).
- It is particularly suited for hard candies, throat lozenges, toothpaste, and similar products.
- When combined with peppermint oil or menthol, the cooling intensity is significantly enhanced.
Features & Benefits
- WS-5 delivers the strongest cooling effect among cooling agents, with an intensity approximately 3–4 times that of menthol and about two and a half times that of WS-3, while maintaining a smooth and rounded flavour profile.
- Offers superior stability compared to menthol and other traditional cooling agents, making it ideal for formulations requiring consistent and prolonged cooling.
- Generally recognised as safe (GRAS) for use in food, cosmetics, and personal care products when applied within recommended concentrations.
- Key process control focuses on bitterness elimination to ensure optimal sensory quality.
- Cooling sensation primarily targets the roof of the mouth and the back of the tongue.
