What is Menthoxypropanediol WS-10?
WS-10, also known as menthoxypropanediol or Symcool WS-10, is a synthetic cooling agent widely used in personal care products, cosmetics, and oral care formulations. WS-10 belongs to a family of compounds called carboxamides, including WS-3, WS-5, and WS-23. It works by activating the TRPM8 receptors in the skin, creating a sensation of coolness without actual temperature change. Menthoxypropanediol WS-10 consists of a menthol molecule attached to a propanediol group, which enhances its stability and modifies its sensory profile. According to the U.S. Food and Drug Administration (FDA), menthoxypropanediol WS-10 is approved to be used in the food, cosmetics, and pharmaceutical industries. It has also been evaluated by relevant regulatory authorities like JECFA, EUR-Lex, ECHACHEM, and WHO. The IFRA Transparency List provides a guideline to ensure the use of menthoxypropanediol WS-10 in the pharmaceutical and cosmetic industries.

Menthoxypropanediol WS-10 Uses
Menthoxypropanediol, commonly known as Symcool WS-10, is a synthetic cooling agent that has gained significant popularity in various industries.
Food and Beverage Uses
Though less common than its cosmetic applications, Symcool WS-10 is also found in certain food and beverage products:
- Specialty candies and confections.
- Premium alcoholic beverages.
- Flavored water and sports drinks.
- Functional foods with refreshing properties.
Cosmetic and Personal Care Uses
WS-10 has become a staple ingredient in the personal care industry due to its distinctive cooling properties. Unlike menthol, which can sometimes irritate, Symcool WS-10 provides a milder, longer-lasting cooling effect without the strong minty odor.
Common cosmetic applications include:
- Facial cleansers and toners that deliver a refreshing sensation.
- After-sun products that soothe and cool the skin.
- Anti-aging products where the cooling effect helps reduce the appearance of puffiness.
- Lip balms and glosses that provide a pleasant tingling sensation.
Oral Care Uses
The oral care industry has embraced WS-10 for its ability to enhance the cooling sensation in:
- Mouthwashes and breath fresheners
- Toothpastes and tooth whitening systems
- Dental rinses and oral sprays
- Sugar-free chewing gums and mints
What makes WS-10 particularly valuable in oral care is its sustainability—the cooling effect lasts significantly longer than traditional cooling agents.
Pharmaceutical Uses
In the pharmaceutical sector, WS-10 is utilized in various formulations:
- Topical analgesics for muscle and joint pain
- Anti-itch creams and lotions
- Nasal decongestants
- Throat lozenges and sprays
The compound’s cooling effect helps create a sensation of relief without affecting the active medicinal ingredients.
Menthoxypropanediol WS-10 Benefits
Superior Cooling Benefits
WS-10 provides a more intense and longer-lasting cooling effect compared to traditional menthol. The cooling sensation it delivers is often described as “cleaner” and less harsh than menthol, creating a more pleasant user experience in products where a refreshing sensation is desired.
Stability Benefits
One of the most significant advantages of WS-10 is its excellent stability across various formulation types. Unlike some cooling agents that can degrade or lose potency over time, WS-10 maintains its cooling properties throughout a product’s shelf life, ensuring consistent performance.
Versatility in Formulations
Menthoxypropanediol works effectively across a wide range of product types, including:
- Facial cleansers and masks
- After-sun care products
- Muscle relief gels and creams
- Oral care products
- Hair care formulations
- Foot care products
Lower Irritation Benefits
For many consumers with sensitive skin, traditional menthol can cause irritation or discomfort. WS-10 typically offers a gentler cooling effect with less potential for irritation, making it suitable for a broader range of skin types.
No Strong Odor
Unlike menthol, which has a distinctive minty scent that can conflict with product fragrances, WS-10 is virtually odorless. This property gives formulators greater flexibility in creating products with specific fragrance profiles without interference.
As consumer demand for multi-sensory products continues to grow, menthoxypropanediol WS-10 is likely to play an increasingly important role in product development.
Menthoxypropanediol WS-10 Used in Cosmetics
A Method for Preparing Cooling Wet Wipes
