Description

Dl-Isomenthol CAS NO 3623-52-7 is a synthetic stereoisomer of menthol, valued for its characteristic cooling and minty organoleptic properties. This versatile compound is essential for formulators seeking a consistent and cost-effective alternative to natural menthol isomers. It is primarily utilized in the fragrance and flavoring industries, as well as in pharmaceutical and personal care applications where a reliable cooling sensation is required.

Application

• Flavor & Fragrance (F&F) Industry: A key cooling agent and flavor modifier in mint, peppermint, and other confectionery, oral care products (toothpaste, mouthwash), chewing gum, and beverages.
• Pharmaceuticals: Used as a topical analgesic and counter-irritant in creams, ointments, balms, and patches for its soothing, cooling effect on skin and mucous membranes.
• Personal Care & Cosmetics: Incorporated into aftershaves, lotions, shampoos, and skincare products to provide a refreshing and invigorating sensory profile.
• Aromatherapy & Inhalants: Employed in decongestant rubs, inhalers, and diffuser blends for its perceived clearing and cooling respiratory benefits.
• Industrial Applications: Acts as an intermediate in the synthesis of other fine chemicals, esters, and derivatives for specialized organic reactions.
• Tobacco Industry: Used as a flavoring agent in certain tobacco products to enhance taste and provide a cooling mouthfeel.
