WS-23 is a popular cooling agent used in various consumer products, particularly in the food and beverage industry, cosmetics, and personal care products. It is widely used to create a cooling or refreshing sensation when applied to the skin or consumed.
Key Information About WS-23:
- Full Name: WS-23 is also known as N-Ethyl-2-(2-methylphenyl)thiazol-3-ylamine.
- Type: It is a synthetic cooling agent and is a part of the family of “cooling agents” like WS-3, WS-5, or menthol.
- Cooling Sensation: WS-23 has a mild and long-lasting cooling effect, providing a sensation similar to menthol but without the strong odor. The cooling effect is often described as smoother and more subtle compared to traditional menthol.
Uses of WS-23:
- Food and Beverages: WS-23 is used in products such as candies, gums, soft drinks, and ice creams to give them a cooling, refreshing sensation. It can be used in place of menthol to avoid the strong flavor that menthol imparts, while still providing a similar cooling effect.
- Cosmetics and Personal Care Products: In skincare, body lotions, lip balms, and shower gels, WS-23 is used for its cooling effect, providing a refreshing feel on the skin. It is often added to products designed to soothe or cool the skin after exposure to heat or sunlight.
- Vaping: Many e-liquid manufacturers use WS-23 in combination with menthol or other flavorings to create a “cooling” sensation for users of vapes. It’s popular in menthol-flavored e-liquids.
- Topical Applications: It is used in products like pain relief creams and muscle balms for its cooling properties, which help provide a soothing feeling after application.
Benefits of WS-23:
- Milder Cooling: WS-23 delivers a cooling effect that is less intense and more pleasant than other cooling agents like menthol or WS-3.
- Non-irritating: Unlike menthol, WS-23 does not cause skin irritation or sensitivity in most cases, making it ideal for people with sensitive skin.
- Long-lasting Effect: The cooling sensation lasts longer compared to other cooling agents, providing prolonged refreshment.
How WS-23 Works:
WS-23 works by activating TRPM8 receptors in the skin or mouth, which are the same receptors that respond to cold temperatures. When these receptors are activated, they send signals to the brain, creating a cooling sensation. However, unlike menthol, which has a strong taste or aroma, WS-23 provides a more neutral and less pungent experience.
Concentration Levels:
- WS-23 is typically used in low concentrations, ranging from 0.1% to 1% in products, depending on the desired intensity of the cooling effect. Higher concentrations can lead to a more intense cooling sensation, but may also become uncomfortable for some users.
Safety and Handling:
- GRAS Status: WS-23 is Generally Recognized as Safe (GRAS) when used in food and beverages, according to regulatory authorities in various regions (such as the FDA in the US).
- Skin Safety: It is generally safe for topical use, though, as with any cosmetic ingredient, it is important to test for allergic reactions or irritation on a small patch of skin before widespread use.
Where to Buy WS-23:
You can find WS-23 through several suppliers of flavoring agents or cosmetic ingredients. Some well-known suppliers and marketplaces for purchasing WS-23 include:
- Alibaba / 1688: Many wholesalers sell WS-23 for use in e-liquids, food products, and cosmetics.
- Ingredient suppliers: Companies that specialize in supplying ingredients to cosmetic or e-liquid manufacturers (e.g., The Perfumers Apprentice, ChemSources, etc.) often stock WS-23.
Conclusion:
WS-23 is an excellent alternative to traditional menthol-based cooling agents, offering a subtle, long-lasting, and pleasant cooling effect without the strong odor or taste of menthol. Whether you’re formulating products for the food, beverage, cosmetics, or vaping industries, WS-23 can be an effective way to deliver that refreshing, cooling sensation that customers enjoy.
