Crude Mentha Oil

Cornmint Oil — Natural — Mentha arvensis — Essential Oil Exporter from India Zentish Exim Pvt Ltd exports — natural Cornmint Oil — steam distilled from — Mentha arvensis — to pharmaceutical manufacturers, flavor houses, cosmetic formulators, and essential oil distributors across the United States. India is the world's dominant producer of cornmint oil, accounting for the majority of global supply. The crop is concentrated in Uttar Pradesh, where generations of cultivation and distillation infrastructure have made Indian cornmint oil the reference standard for the global menthol supply chain. Cornmint oil is the primary raw material from which natural menthol crystals, menthol powder, and menthol liquid are produced. If your business uses any natural menthol derivative, it almost certainly traces back to — Mentha arvensis — oil at some point in the supply chain. Buyers who source cornmint oil directly — rather than downstream menthol derivatives — are typically flavor and fragrance houses, large-scale essential oil blenders, or manufacturers with in-house dementholization capacity. Product Overview Cornmint oil is produced by steam distillation of the aerial parts of — Mentha arvensis — at the flowering stage. The crude distillate — sometimes referred to as "natural mint oil" or "Indian mint oil" — contains a high concentration of free L-menthol, typically 70 — 80% by GC, along with menthone, isomenthone, menthyl acetate, and minor terpene components. This crude oil is the starting material for menthol crystal production via partial freezing and crystallization. Cornmint oil is also sold as a finished product — either as crude oil (with natural menthol content intact) or as dementholized cornmint oil (DMO), from which the majority of menthol has been removed. Buyers looking to use the oil directly in formulations typically specify the crude or partially dementholized form. Buyers seeking a base oil for further menthol extraction specify crude oil with the highest possible menthol content. We supply both crude and dementholized grades. Purity and composition are confirmed by GC analysis on every production batch. Key Specifications Natural Cornmint Oil — Technical Data DMO (dementholized cornmint oil) specifications vary depending on the degree of dementholization. Residual menthol content in DMO typically ranges from 30 — 50% depending on buyer requirement. Custom dementholization levels are available for FCL quantities. Please specify your required menthol range when requesting a quotation for DMO grades. Physical Properties Crude cornmint oil is a colorless to pale yellow mobile liquid with an intensely fresh, minty-cooling odor. It is perceptibly sharper and more camphoraceous than peppermint oil — a characteristic often described as "raw" or "green" compared to the rounder peppermint profile. This is not a defect; it is an inherent characteristic of the higher-menthol, lower-ester composition. The oil is sensitive to oxidation and light. Exposure to air over time can lead to menthol oxidation byproducts and off-note development. All shipments are packed in sealed, opaque containers, and nitrogen flushing is available for long-transit orders. Physical State: — Mobile liquid Color: — Colorless to pale yellow Flash Point: — Approximately 85 — C (crude) Stability: — Sensitive to light, air, and high temperature Miscibility: — Miscible with ethanol, ether; immiscible with water Water Content: — NMT 0.5% (Karl Fischer) Crude Cornmint Oil vs Dementholized Cornmint Oil — Which Do You Need? This is the most important specification decision for cornmint oil buyers, and the answer depends entirely on your end use. Crude Cornmint Oil Contains natural menthol at 70 — 80% by GC. This is the starting material for menthol crystal/powder/liquid production via freezing and crystallization. It is also used directly in some industrial flavoring applications where a high-menthol, strong-cooling oil is acceptable or preferred. Buyers who purchase crude oil for further processing should confirm their dementholization or crystallization setup before ordering, as crude oil handling requires the same temperature awareness as the menthol products derived from it. Dementholized Cornmint Oil (DMO) Produced by chilling crude oil to precipitate and remove menthol crystals, leaving an oil with reduced menthol content but a distinctly different, more complex aromatic profile. DMO has a fresher, greener, slightly herbal character that makes it useful as a flavoring agent and fragrance component in applications where high free menthol is not desired. It is used in oral care, personal care, and food flavoring as a supporting mint note or modifier.
