Menthol is an organic compound, specifically a monoterpenoid, that occurs naturally in the oils of several plants in the mint family, such as corn mint and peppermint.It is a white or clear waxy crystalline substance that is solid at room temperature and melts slightly above.
p-Menthane-3,8-diol, also known as para-menthane-3,8-diol, PMD, or menthoglycol, is an organic compound classified as a diol and a terpenoid.It is colorless. Its name reflects the hydrocarbon backbone, which is that of p-menthane.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise. The substances are listed in alphabetical order.

The oil has been used for various purposes over centuries. [ 1 ] Peppermint extract is commonly used in cooking , as a dietary supplement , as an herbal or alternative medicine , as a pest repellent, and a flavor or fragrance agent for cleaning products, cosmetics, mouthwash, chewing gum, and candies.
Terpineols have been isolated from a variety of sources such as cardamom, cajuput oil, pine oil, and petitgrain oil. [2] Four isomers exist: α-terpineol, β-terpineol, γ-terpineol, and terpinen-4-ol. β-Terpineol and γ-terpineol differ only by the location of the double bond. Terpineol is usually a mixture of these isomers with α-terpineol ...
Menthone was first synthesized by oxidation of menthol in 1881, [6] [needs update] [7] before being found as a component in essential oils in 1891. [ citation needed ] Of the isomers possible for this chemical structure (see below), the one termed l -menthone —formally, the (2 S ,5 R )- trans -2-isopropyl-5-methylcyclohexanone (see infobox ...
Validol, the anxiety medication containing a roughly 25% solution of menthol in menthyl isovalerate is prepared essentially in one step, in which the amount of menthol added before conducting the acid catalysed esterification is in an excess such that the resulting solution of the yielded ester has around 25% menthol, simplifying the procedure.
