Cooling Agent WS-23 Flavour Concentrate?
Leave a message
WS-23 is a synthetic cooling agent widely used in food, oral care, and electronic vaporization products. It provides a strong, pure cooling sensation without taste, odor, or the pungency of menthol. It is included in China's food additive standard GB 2760 and is also an permitted additive in China's national standard for e-cigarettes.
🔬 What is WS-23?
Basic Information: Its chemical name is N,2,3-Trimethyl-2-isopropylbutamide. It typically appears as a white crystalline powder with a minty aroma but no irritating pungency.
Key Characteristics: WS-23 is known for its potent cooling effect, which can last for 15 to 30 minutes. It is stable at high temperatures, and its cooling intensity is not affected even at 200°C. Unlike menthol, it has almost no odor or taste and is low in volatility.
Common Uses: It is widely used to provide a cooling sensation in products such as candy, gum, toothpaste, beverages, tobacco, pharmaceuticals, and cosmetics.
💡 Applications and Safety Research
WS-23 is often used with flavors to enhance the sensory experience. Here are its main application areas:
| Field | Application Examples |
|---|---|
| Food & Beverage | Candy, chewing gum, beverages, jellies, jams, dairy products |
| Oral & Health Care | Toothpaste, mouthwash, other oral care products |
| Tobacco & E-Cigarettes | Cigarettes, e-cigarette liquids (as a permitted additive) |
| Cosmetics & Pharmaceuticals | Skin contact products, some pharmaceutical formulations |
Regarding safety, particularly for inhalation as in e-cigarettes, a joint study by the Chinese Academy of Sciences Shenzhen Advanced Institute and RELX悦刻 in 2022 suggested that WS-23 itself does not possess rewarding properties in animal models. The study concluded that its rewarding property may be lower than that of pure nicotine products, suggesting it does not contribute additional addiction risk.
⚠️ Important Considerations
Distinguish Between Uses: Although WS-23 is approved for use in food and e-cigarettes, the safety conclusions for inhalation are primarily based on specific scientific studies. Always purchase from reputable suppliers who can provide specifications for the intended use (e.g., food grade).
Follow Local Regulations: The approval and permitted scope of use for food additives and e-cigarette ingredients may vary by country and region. Please comply with local laws and regulations when using them.
