Menthone Glycerin Acetal
Menthone Glycerin Acetal (D,L-Menthone 1,2-glycerol ketal), also known as menthone glycerol ketal, is a clear, colourless viscous liquid with a slight minty aroma that is almost imperceptible on the tongue but delivers a lingering, pleasant cooling effect. Available in both racemic and levorotatory specifications—with the levorotatory form predominant in commercial offerings—it is synthesised as a cooling agent through the acid-catalysed dehydration and condensation of menthone with glycerol.

Application & Uses
- Menthone glycerol ketal is commonly applied in personal care products such as shampoos, shower gels, shaving products, toothpastes, mouthwashes, conditioners, body washes, soaps, lotions, creams, after-shave products, sunscreens, and antiperspirants.
- It serves as a cooling stabiliser for mint fragrances and is used in the formulation of daily chemicals, tobacco products, cooling fragrances, food & beverages (chewing gum, confectionery, chocolates, dairy products, baked goods, beverages, alcoholic drinks), and pharmaceuticals (topical analgesics, cough syrups, lozenges, nasal sprays, OTC medicines).
Features & Benefits
- Compared to menthyl lactate, menthone glycerol ketal delivers a milder cooling sensation whilst serving as both an immediate and long-lasting cooling agent. Non-irritating and menthol-free, it provides cooling effects akin to traditional menthol, with optimal pH range of 6-12 and easy incorporation as a colourless liquid that is non-irritating on cold skin application.
- As a sensory modulator, its weak minty odour preserves fragrance integrity while offering refreshing, long-lasting cooling (up to 25 minutes) suitable for broad applicability across personal care, food & beverages, pharmaceuticals, and consumer goods.
