🔑 Main differences

  • Isoeugenol vs. Eugenol: Isoeugenol is an isomer of eugenol, with a more floral and softer character; eugenol itself is sharper and more clove-like.
  • Methyl Isoeugenol: Has a sweeter nuance, but is under strict scrutiny due to toxicological concerns.
  • Acetyl Isoeugenol: Used primarily to deepen rose and carnation accords, but should only be used in very low doses.
  • Eugenol natural 100% FG by Robertet: Premium quality, all-natural and food grade, specially developed for perfumery and aromatic applications.
