Description

L-Menthol CAS NO 2216-51-5 is the naturally occurring, optically active stereoisomer of menthol, prized for its characteristic cooling sensation and refreshing mint aroma. This high-purity compound is a critical ingredient for formulators requiring consistent sensory and physiological effects. It is essential for manufacturers in the flavor & fragrance, pharmaceutical, and personal care industries seeking reliable, high-quality raw materials for premium products.

Application

• Flavor & Fragrance Industry: A primary cooling and mint flavoring agent in confectionery, chewing gum, oral care products (toothpaste, mouthwash), beverages, and tobacco.
• Pharmaceuticals: Used as a topical analgesic and counterirritant in creams, ointments, balms, and patches for muscle pain, cough suppressants (lozenges), and nasal decongestants.
• Personal Care & Cosmetics: Provides a cooling sensation in skincare products (lotions, aftershave), lip balms, shampoos, and soaps for a refreshing user experience.
• Aromatherapy & Inhalants: Employed in vapor rubs, inhalers, and diffuser blends for its perceived respiratory and soothing benefits.
• Industrial Applications: Acts as an intermediate in organic synthesis and as a mild antiseptic or deodorizing agent in certain formulations.
