Application & Uses
-
Commonly used in mint-flavoured oral care fragrances, confectionery, and chewing gum. At low usage levels, imparts freshness to berry, citrus, and other fruit flavours.
- Oral care (toothpaste, mouthwash), cosmetics (creams, lotions), pharmaceuticals, personal care (shampoos, conditioners); enhances refreshing quality in food and drinks due to powerful cooling effect.
Features & Benefits
- Non-volatile, odourless, and tasteless; no cooling when tasted directly but activates when crushed into fine powder.
- Delivers impactful, fresh, long-lasting cooling (longest duration among WS series) without menthol's burning or pungent aftertaste; strongest initial effect with extended longevity compared to other WS agents.
- Enhances sustained cooling when combined with other WS agents; alone, exhibits poor solubility and heavy bitterness; more stable than menthol for consistent long-term cooling. Heat-resistant up to 200°C.
- Acts on front of tongue, entire oral mucosa, and throat.
