Pennyroyal Essential Oil CAS 8013-99-8

“European” Pennyroyal Oil is a pale yellow to almost colorless mobile liquid of very fresh, strong, herbaceous-minty, but not very bitter odor (in contrast to the “American” type). The flavor, however, is distinctly bitter, with a slightly coolminty and strongly herbaceous note. The oil is rarely, if ever, used in flavors. It finds some application in perfumery, e.g. in the reproduction of certain essential oils (geranium, etc.). Furthermore, it is used along with rosemary, lavandin, sage, sassafras, citronella, white camphor and other low-cost oils for industrial perfumes, fragrances for detergents and household products, etc. Its main use has been as a starting material for the production of “synthetic” menthol from Pulegone which is present at the rate of up to 96% in the Moroccan pennyroyal oil.

Mentha pulegium, commonly (European) pennyroyal, or pennyrile, also called squaw mint, mosquito plant and pudding grass, is a species of flowering plant in the Lamiaceae family, or mint family, native to Europe, North Africa, and the Middle East.

Pennyroyal is toxic to humans and has differing effects dependent on the volume and concentration ingested. The most concentrated and toxic form of the pennyroyal plant is pennyroyal oil. The oil is distilled from the slightly dried herb and contains 80% to 92% of cyclohexanone pulegone. Pulegone, the molecule in highest concentration in the pennyroyal plant, causes a variety of ailments in those who ingest it and is what causes the plant to have its peppermint flavour.
