DL-Menthol Usage And Synthesis
Flavors and fragrances
Menthol is a cyclic terpene alcohol flavors and fragrances with its appearance exhibiting colorless needle or shuttle columnar crystal or white crystalline powder. It has special aroma of mint with its taste being hot at first but then being cool later. It exhibit neutralizing reaction in the ethanol solution, being extremely easily soluble in ethanol, chloroform, petroleum ether, ether, liquid paraffin or volatile oil and being very slightly soluble in water.
First aid of poisoning
Topical application of menthol have effects of promoting blood circulation and anti-inflammatory, anti-itching and can be applied to anti-inflammatory, antipruritic, analgesic and reducing swelling and so on.
(1) Chemical qualitative method
L-form appears as colorless needle crystal. The melting point is 42-43 °C; the boiling point is 216 °C, the specific rotation:-51 °-45 °; the flash point: 93 °C; the relative density: 0.8810; it is soluble in ethanol and is miscible with oil. It has cool, fresh, pleasant mint characteristic aroma with sweet spiky gas. It gives people a cold feeling with aroma penetrating through the hair, but not lasting. The taste is also fresh sweet cool taste.
It is mainly used in medicine, toothpaste, toothpaste and mouthwash with its cool taste being able to enhance the smell of peppermint oil, having effect of refreshing the brain as well as disinfection effects. It can also be used as spices to be applied to the colognes. Application of appropriate amount of low-grade soap and detergent fragrance such as roses, geraniol, lavender and fragrant has effects of enhancing the tone and aroma. It can also be applied to food flavors and flavor for wine and tobacco.
colorless to white crystalline solid
A chemical which triggers cold-sensitive TRPM8 receptors in the skin neurons in vitro.
In liqueurs, confectionery, perfumery, cigarettes, cough drops, and nasal inhalers.
White crystalline solid with a peppermint odor and taste.
Air & Water Reactions
Insoluble in water.
DL-Menthol is incompatible with butyl chloral hydrate, camphor, phenol, chloral hydrate, Exalgine, betanaphthol, resorcinol or thymol in triturations; potassium permanganate, chromium trioxide and pyrogallol. DL-Menthol is also incompatible with strong oxidizers.
DL-Menthol is combustible.
