Scent

Intensely floral: tuberose-ylang with lactonic creaminess and solar warmth. A sweet-fruity edge and subtle animalic undertone. More potent and diffusive than most floral esters. Solar and slightly tropical.

Evolution over time

Immediately

Bright tuberose-ylang burst, solar and creamy

After a few hours

Lactonic floral warmth, animalic undertone

After a few days

Persistent sweet-floral trace, long-lasting

The Full Story

Cyclopidene (CAS 40203-73-4, methyl 2-cyclopentylideneacetate) is a synthetic floral molecule with powerful tuberose and ylang-ylang character. It provides excellent diffusion and lift in white-floral compositions.

The scent is intensely floral: lactonic-creamy, solar, with sweet-fruity edge and subtle animalic undertone connecting it to natural tuberose headspace.

In perfumery, cyclopidene functions as a heart note. It can substitute methyl salicylate, methyl benzoate, or methyl paracresol. Used at low dosages (under 1%) due to potency.

Did You Know?

Did you know?

Despite being called tuberose acetate, cyclopidene is chemically a methyl ester, not an acetate. The trade name reflects olfactory character rather than chemistry.
