Peppermint Essential Oil Piperita CAS 8006-90-4

True peppermint oil is steam distilled from the partially dried herb of Mentha Piperita which is a hybrid from three other species of Mentha, all natives of southern Europe.

Natural Peppermint Oil is a pale yellow or pale olive colored liquid of fresh, strong, somewhat grassy-minty odor with a deep balsamic-sweet undertone and a sweet, clean dryout note. The grassy topnote may disappear or fade after proper ageing of the oil (polymerization of the lower aldehydes, etc.). Even the odor gives an impression of coolness, often due to the psychological effect of associating the known flavor with the impression of the odor.
