L-Monomenthyl Glutarate (CAS 220621-22-7), also known in the industry as Tanga, is a premium odorless cooling agent formed by esterifying L-menthol with glutaric acid. It combines an exceptionally long cooling duration with virtually zero odor and zero taste — solving the classic problem of menthol-type coolants interfering with delicate flavor and fragrance systems. It is especially popular in premium cosmetics, oral care and flavor formulations where “pure cooling, nothing else” is required.

Cooling Profile & Sensory Characteristics
L-Monomenthyl Glutarate delivers a mild, smooth and remarkably persistent cooling sensation — noticeably longer than menthol and with a far gentler onset. Because the molecule is essentially odorless and tasteless, it can be used at effective levels in fine fragrances, skincare and premium food flavors without imparting any minty character. The cooling effect is frequently described as “cool from within”: comfortable, even and non-numbing. It is an excellent partner to WS-23 (for strength) and L-Menthyl Lactate (for natural feel) in multi-component cooling systems.
Applications of L-Monomenthyl Glutarate
Cosmetics & Skin Care
Moisturizers, serums, masks, after-sun — long-lasting cooling with zero fragrance conflict.
Oral Care
Toothpaste, mouthwash — clean cooling that never masks the flavor system.
Food & Beverage Flavors
Confectionery, beverages — subtle physical cooling without mint taste.
Fine Fragrance
Perfumes and colognes — a fresh cool top-note effect with no odor contribution.
Recommended Use & Dosage
Typical use levels range from 100 to 1,000 ppm in finished products, adjusted by application and desired intensity. In leave-on cosmetics, 0.1–0.5% is common; in flavors and oral care, 100–500 ppm provides a distinct cooling effect. Contact our technical team for precise formulation recommendations.
