DL-Menthol USP

DL-Menthol USP is a high-purity, racemic cyclic alcohol used as a cooling agent, counterirritant, flavoring, and aromatic component in topical, oral, and inhalation pharmaceutical formulations. Offering a characteristic minty aroma and a pronounced cooling effect on skin and mucous membranes, DL-Menthol is widely employed in analgesic, decongestant, and antipruritic products. DL-Menthol USP

• Is a USP-compliant racemic form of Menthol (DL-Menthol)
• Delivers cooling sensation and mild anesthetic effect
• Is suitable for topical creams, balms, lozenges, oral sprays, and vapor therapies
• Is used in over-the-counter analgesics, cough suppressants, and antipruritic formulations
• Is manufactured under Good Manufacturing Practice (GMP) conditions
• Is supplied with complete regulatory documentation including Certificate of Analysis (CoA) and supporting technical data

DL-Menthol (Racemic Menthol) is a white, crystalline solid or clear liquid (depending on temperature) with a minty odor and flavor. Unlike natural L-Menthol, which is derived from Peppermint oil, the racemic mixture is synthetically produced and contains both D- and L-enantiomers, offering balanced sensory properties and consistent performance.

In pharmaceutical and personal care applications, DL-Menthol USP is used in:

• Topical analgesics and muscle rubs to soothe sore muscles and joints
• Medicated lozenges and sprays for throat relief and cough suppression
• Inhalation products and chest rubs for sinus congestion and upper respiratory support
• Antipruritic creams and lotions to relieve itching and irritation
• Oral hygiene products such as toothpaste and mouthwash

Menthol activates cold-sensitive TRPM8 receptors in the skin and mucosa, creating a cooling sensation that distracts from pain or irritation. It also exhibits mild local anesthetic and antipruritic activity.
