What Eugenol does

  • Gives a warm, clove-like scent
  • Adds spicy notes to fragrance blends
  • Helps balance other scent notes

Eugenol is a naturally occurring compound, most famously found in clove oil. Other plants, including cinnamon leaf and bay, also contain it. Producers often isolate it from these oils, though it can also be made synthetically.

Formulators use eugenol for its warm, clove-like scent, which pairs well with vanilla, citrus and woody notes. It dissolves well in oils, so it blends easily into creams and lotions. A little goes a long way, since its scent is strong.

Frequently asked questions

Is eugenol safe for skin?

Eugenol is used in many products as a fragrance and is well tolerated by most people. It is one of the labeled fragrance allergens, though, so anyone with a known sensitivity should check labels and patch test new products first.

Is eugenol the same as clove oil?

Not quite. Eugenol is the best-known compound in clove oil, but the oil also contains other plant compounds. Eugenol on its own is the single molecule that gives the spicy scent.
