Description

(-)-Menthyl Lactate CAS NO 59259-38-0 is a high-purity, optically active ester derived from natural menthol and lactic acid, valued for its unique cooling sensation and refreshing mint-like aroma. This compound is a critical ingredient for formulators seeking to enhance sensory profiles with a clean, long-lasting cooling effect without the pungency of menthol. It is primarily needed by manufacturers in the flavor & fragrance, personal care, and pharmaceutical industries for premium product development.

Application

• Flavor & Fragrance Industry: Used as a cooling and refreshing agent in chewing gums, candies, oral care products (toothpaste, mouthwash), and mint-flavored beverages.
• Personal Care & Cosmetics: Incorporated into skincare products, aftershaves, lip balms, and body lotions to provide a soothing, non-irritating cooling sensation.
• Pharmaceuticals: Employed as a flavor enhancer and cooling agent in medicated lozenges, throat sprays, and topical analgesic or anti-itch formulations.
• Aromatherapy & Wellness: Used in essential oil blends, massage oils, and cooling gels for its refreshing and invigorating properties.
• Tobacco Industry: Applied as a flavor modifier and cooling additive in certain tobacco products.
• Industrial Applications: Can serve as a chiral intermediate or solvent in specialized organic synthesis due to its defined stereochemistry.
