Description

(+)-Isomenthol CAS NO 23283-97-8 is a high-purity stereoisomer of menthol, prized for its distinct organoleptic and cooling properties. This compound is essential for formulators seeking to create sophisticated sensory profiles with precise stereochemical control. It is a critical ingredient for manufacturers in the flavor and fragrance, pharmaceutical, and personal care industries, where its unique sensory characteristics and purity are paramount for product performance and consumer safety.

Application

• Flavor & Fragrance Industry: A key chiral building block for creating minty, cooling, and refreshing notes in fine fragrances, oral care products (toothpaste, mouthwash), chewing gums, and confectionery.
• Pharmaceutical Synthesis: Used as a chiral intermediate or active ingredient in the production of topical analgesics, antipruritics, and decongestants, leveraging its cooling and mild anesthetic effects.
• Personal Care & Cosmetics: Incorporated into formulations for aftershaves, lotions, balms, and skincare products to provide a clean, cooling sensation and enhance the user experience.
• Tobacco & E-liquids: Employed as a flavoring agent to impart a characteristic minty coolness to tobacco products and vaping liquids.
• Chemical Synthesis: Serves as a valuable chiral starting material or resolving agent in asymmetric synthesis for the production of other fine chemicals and active pharmaceutical ingredients (APIs).
• Aromatherapy & Inhalants: Used in therapeutic balms, inhalers, and diffuser blends for its perceived soothing and clearing properties.
