Heart note CAS# 2437-25-4 Manufacturer: IFF Odor description: ozonic-metallic, waxy, cool, citrus nuances Clonal is a very strong molecule from the nitrile group with an abstract fresh scent. Like all nitriles, it is not the easiest to use. Once its power is mastered, it will bring a modern, ozonic-citrus twist to our creations. NOTE: We recommend diluting to 1% or even 0.1% for easier dosing.
