Molecule 03 consists of Vetiveryl Acetate, pure and singular.
Vetiveryl Acetate could be described as a hybrid molecule, half-natural, half-synthetic. It is a fraction of vetiver oil, distilled from the roots of an Indian grass, which is then ‘crossed’ with acetic acid to remove the bitter and leathery aspects of the root.
The result is an elegant and refined molecule with the woody, slightly grassy character of vetiver, but far smoother and softer. “Acetylation also brings out the grapefruit touch in vetiver,” says Geza Schoen, “giving a more pronounced bitter-fresh top note.” 

Notes
The Molecule 03 fragrance is radically minimalist. It contains no odorants except the aroma-molecule, Vetiveryl Acetate. Those customers who find the Molecule fragrances too subtle may wish to try the Escentric fragrances, which will always have a more powerful diffusion.
