Cooling Agent WS-10

Product Description

What is Cooling Agent WS-10？

Cooling Agent WS-10 (Menthoxypropanediol) is a highly efficient, synthetic derivative of menthol known for delivering a strong, long-lasting cooling effect on the skin and mucous membranes. Unlike natural menthol, WS-10 is virtually odorless and tasteless, making it ideal for products where a refreshing sensation is desired without a minty scent.

WS-10 (Menthoxypropanediol) provides a long-lasting cooling effect (Strength 4.5) without the minty odor or taste associated with menthol (Strength 1) . It can be used in lower concentrations compared to menthol while achieving a similar cooling effect.

Cooling Agent WS-10 Specification

Cooling Agent WS-10 Key Characteristics

• WS-10 exhibits very low volatility with virtually no aroma; recommended food usage is 0.01%–0.005%.​
• Provides intense cooling with a heavier taste profile, menthol-like olfactory notes, mild stimulation, and bitterness; at >50 mg/L, delivers long-lasting, distinctly menthol-like cooling.​
• Features two alcohol hydroxyl groups for improved water solubility (though not fully water-soluble) and good oil solubility; combines effectively with WS-3, WS-23, and menthyl lactate in solvent-free systems, ideal for daily fragrance formulations.
• WS-10 threshold 1 ppm (20%–100% menthol equivalent), 100 ppm sustains 20–25 minutes cooling (twice menthol); WS-10 2S isomer 2–3× stronger than 2R, 1.5–2× stronger than racemic.
• Acts on oral cavity (front of tongue, palate, front of throat) and skin, lasting up to 12 minutes.
• Generally recognised as safe (GRAS) for food and cosmetics within recommended concentrations.
