What are menthol crystals?

Menthol crystals are obtained from Mentha arvensis, also known as corn mint, Mild mint, Filed mint, and Japanese mint. The process starts with a distillation of mint leaf that results in peppermint essential oil, which is then cooled to a temperature of -22 degrees Celsius. The process of freezing causes the crystallization, producing menthol crystals.

Menthol crystals look like tiny, transparent, brittle, crystalline crystals at room temperature. At temperatures that are above room temperature, however, they are easy to melt and dissolve in essential oils, water, oil, or alcohol. 

When applied to the skin, menthol crystals contribute a cooling sensation and strong aromatic scent. In addition, menthol crystals have a large degree of adaptability, making them easy to incorporate into a broad spectrum of DIY cosmetics, oral hygiene products, skincare, and hair care products helping with many health and skin issues.


History of menthol crystals.

Menthol crystals have been a medicinal ingredient for thousands of years, although the exact origin is unknown. Before discovering mint crystals, ancient Egyptians used a peppermint plant for its healing properties, while the ancient Greeks and Romans used it to treat respiratory illnesses.

In the 17th century, English scientist Thomas Sydenham was the first to isolate menthol. He was using a distillation process to extract essential oils from plants and discovered that menthol had a cooling effect on the skin.

By the 19th century, menthol crystals were widely used in medicines, such as cough syrups and lozenges. In 1885, German scientists discovered that menthol could be synthesized in the laboratory, allowing for further experimentation with its effects on humans. 

Since then, researchers have studied menthol’s ability to reduce pain, inflammation, and congestion in the airways due to colds or allergies. It is still widely used in many over-the-counter medications and home remedies to relieve symptoms of colds and other ailments. Many breath fresheners and mouthwashes contain menthol.
