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.
