Menthol

CAS: 1490-04-6

Overview

Menthol (CAS 1490-04-6 ), also identified by FEMA 2665 , is a naturally derived or synthetically produced cyclic alcohol extracted primarily from peppermint and cornmint oils. It delivers a characteristic cooling sensation without a temperature change.

This unique property makes it a high-demand active in flavoring, fragrance, and pharmaceutical applications. In oral care and confectionery, it provides the cooling and flavor profile expected in toothpastes and mouthwashes.

It is also essential for chewing gums and mint-flavored candies. Pharmaceutical manufacturers incorporate it into topical analgesics, throat lozenges, nasal decongestants, and cough suppressant formulations as a functional cooling agent.

Personal care producers use it in shaving products, lip balms, and skin cooling gels where the sensory effect is a primary performance attribute. It serves as a critical ingredient for products requiring a refreshing feel.

Tobacco and e-liquid blending represents a significant industrial volume application. In these sectors, it is used to modify harshness and deliver a distinctive flavor character that consumers expect from mentholated products.

The product is supplied as colorless to white crystals or flakes, with natural and synthetic variants available. Established grades include USP , BP , and Ph. Eur. , as well as food-grade specifications.

Natural l-menthol often commands a premium over racemic synthetic material in the global market. Bulk supply is available in fiber drums or cartons, with purity typically at 99% or above for pharmaceutical and flavor-grade material.
