Peppermint essential oil is composed of 38% to 48% menthol (a monoterpene alcohol), 20% to 30% menthone, and about 6% 1,8-cineole (aka eucalyptol, which we discussed in the post on eucalyptus!) Menthol is the most interesting part of peppermint as it’s the compound that gives us that cooling sensation we seek when we add it to our products….
