Mentolos

Mentolos refers to menthols, a family of monoterpene alcohols derived from mint oils. The best-known member is menthol, a naturally occurring cyclic monoterpene alcohol that provides the characteristic cooling sensation of peppermint. The term encompasses several stereoisomers and related compounds used commercially as flavors, fragrances, or cooling agents.

Menthols occur predominantly in the essential oils of Mentha species, especially Mentha arvensis (cornmint) and Mentha piperita (peppermint). They can be extracted from plant material, concentrated, and refined. A significant portion of global supply is produced synthetically via routes that start from pulegone or related intermediates, involving hydrogenation, isomerization, and purification steps to yield the desired menthol enantiomer, often the (-)-menthol.

Menthols are chiral compounds with multiple stereoisomers. Naturally occurring menthol is primarily the (-)-enantiomer. The cooling sensation results from activation of the TRPM8 receptor in sensory neurons. They are soluble in lipids and have a characteristic minty odor, making them suitable for use in various flavors and fragrances.

Uses of menthols include flavoring in foods, beverages, toothpaste, gum, and confectionery; fragrance and cooling in cosmetics and personal care products; and active ingredients in topical analgesics, cough drops, and nasal inhalers. They are also used to mask odors or enhance mouthfeel in certain products.

Safety and regulation: menthols are widely used as flavor and fragrance ingredients and are generally regarded as safe when used appropriately. High concentrations can irritate skin or mucous membranes and may be hazardous if ingested in large amounts. Regulatory status varies by jurisdiction, with some authorities restricting menthol levels in foods and cosmetics and requiring labeling.
