Natural Menthol Crystals: Manufactured with Care 

 

Natural Menthol Crystals are produced through a labor intensive process dating back hundreds of years. This tradition employs mint farmers, distillers and manufacturers from Northern India and other mint growing regions. Synthetic manufacturing of Menthol Crystals started in the 1970s. The goal of either process is to produce active L-Menthol.


It starts with Mentha Oil



Mentha Oil is made from mint plants specifically Corn mint (Mentha arvensis) and Peppermint (Mentha piperita). The leaves and whole plants of mint crops are steam distilled to form the oil. Mentha Oil distilled from Corn mint contains higher concentrations of the active component, L- Menthol. 


A brief look at Manufacturing Pure Menthol 


The Mentha Oil is carefully filtered to remove water and naturally occurring impurities. Mentha Oil is then cooled incrementally over a period of time. After cooling, the crystalline portion is isolated from the remaining dementholised oil (DMO). The crystals are spread out in a room designed to slowly dry them with a continuous stream of temperature controlled air. 


Best Manufacturing Practices


Top manufacturers take great care in filtering and cooling Mentha oil. They systematically isolate and dry the crystals into a finished product. The manufacturers we buy from are certified to employ Good Manufacturing Practices (GMP) for each of these steps.Their efforts consistently produce translucent crystals that have a colorless appearance.This type of Menthol is USP grade, valued for its high L-Menthol content and absence of impurities. Any claims in purity have been verified by gas chromatography and other analytical methods. 

Uses of Menthol Crystals 

Flavoring 

Menthol is the backbone of Peppermint flavored products as well as Menthol products. Menthol crystals give products such as toothpaste and mouthwash a strong characteristic mint flavor profile. 

Menthol Fights Pain

Research has shown that tissues of the oral mucosa, skin and muscles experience a numbing, analgesic effect when exposed to Menthol. Healing salves, Oral Sprays and Therapeutic recipes aimed at pain relief regularly contain Menthol.

Menthol as a Denaturant of Alcohol

Pure Menthol is not readily soluble in water, though it melts in warm water. Menthol is completely soluble in pure alcohol. Federal formula 38 b calls for 10 lbs of Menthol Crystals, USP to every 100 gallons of alcohol. This alcohol denatured with Menthol is used in a variety of products such as lotions and creams for the hand, face and body. More products include Anti septic solutions, disinfectants, insecticides, room deodorizers, body deodorant and shampoos.
