Menthol Crystal (Peppermint Camphor)
Cooling sensation, analgesic, antipruritic, nasal decongestant, local anesthetic
Menthol crystal is a purified natural monoterpene alcohol obtained from peppermint oil (Mentha arvensis and M. piperita) through a process of freezing, crystallization, and recrystallization to achieve pharmaceutical-grade purity. This colorless, hexagonal crystalline solid has a characteristic intense peppermint odor and produces a pronounced physiological cooling sensation when applied to skin or mucous membranes, mediated by TRPM8 cold receptor activation. Menthol is one of the world's most important aroma chemicals, used extensively in pharmaceuticals (topical analgesics, decongestants, oral care), food and beverage flavoring, tobacco, cosmetics, and personal care products. Fresure supplies menthol crystal in natural (ex-Mentha arvensis) and synthetic grades, with batch-specific Certificate of Analysis verifying purity (>99%), melting point, optical rotation, and non-volatile residue. Available in various crystal sizes from fine powder to large crystals.

Active pharmaceutical ingredient (API) in topical analgesics (pain relief patches, gels, creams, balms), nasal decongestant inhalers and vaporubs, anti-itch preparations, and throat lozenges. The TRPM8-mediated cooling sensation provides rapid relief from minor pain, itching, and congestion. Also used as a permeation enhancer for transdermal drug delivery.
Primary flavoring and cooling agent in toothpaste, mouthwash, dental floss, and breath fresheners. The characteristic minty flavor is universally recognized and associated with oral freshness and cleanliness. Antimicrobial activity against oral pathogens provides functional benefits alongside flavor.
GRAS-designated flavoring substance (FEMA GRAS 2665). Used in confectionery (especially chewing gum, mints, hard candies), beverages, ice cream, and baked goods. The cooling effect enhances sweetness perception and provides a distinctive sensory signature.
Flavoring and cooling additive in tobacco products (cigarettes, smokeless tobacco). Used in shaving products, after-shave lotions, foot care preparations, and cooling body sprays. The refreshing, tingling sensation is a key sensory cue in masculine personal care.

Custom packaging and private labeling available upon request.
Store in tightly sealed containers in a cool, dry place below 25 deg C. Menthol is volatile and sublimes slowly at room temperature; ensure containers remain sealed. Protect from heat and direct sunlight. Shelf life: 3 years under recommended conditions.
Under recommended storage conditions — tightly sealed in a cool, dry environment away from direct sunlight — Menthol Crystal remains stable for 2 to 3 years. Monitor for any changes in aroma, color, or viscosity before use in production batches.
Menthol Crystal is from the . This method preserves the full spectrum of volatile aromatic compounds and bioactive constituents that define the oil''s therapeutic and sensory profile.
Every shipment includes a Certificate of Analysis (COA) detailing the batch-specific chemical profile (GC/MS or GC-FID), physical parameters (specific gravity, refractive index, optical rotation), and organoleptic assessment. Material Safety Data Sheet (MSDS/SDS) is also provided. Additional documentation — including GC/MS chromatograms, pesticide residue analysis, heavy metal testing, and allergen statements — is available upon request.
