stability
1. The sinistral crystal is colorless acicular crystal. Soluble in ethanol, missoluble with oil. It has a cool, clear, pleasant mint characteristic aroma with sweet prickly notes. It gives a cold feeling and a strong aroma, but it doesn't last long enough. The taste is also fresh, sweet and cool.

2. It exists in flue-cured tobacco leaf, flavoured tobacco leaf and mainstream flue gas.

3. It exists naturally in peppermint oil, Japanese peppermint oil, and a small amount in essential oils such as geranium oil.

4. There are 12 isomers.

5. There are trace amounts of liquid oil and extremely trace amounts of non-volatile substances on the surface of ordinary crystals. The synthesized menthol is a mixture of various isomers.

6. It has certain toxicity, irritation and anaphylaxis.

Water is insoluble
