In short
Liffarome is a trade name for cis-3-hexenyl methyl carbonate, a leaf-alcohol carbonate with a fresh green-fruity odour. It is a more fruity, less sharp alternative to cis-3-hexenyl acetate.
What Liffarome smells like
Liffarome (IFF) is a natural-smelling green with violet-leaf and pear nuances. IFF's own description is a natural-smelling violet-green, pear and grass odour, effective in trace amounts. Distributors describe it as fresh green leaves and cut grass with green apple, pear and peach, and floral hints of violet leaf or iris, and one calls it a softer member of the leaf-alcohol family, with a touch of nasturtium and radish.

What makes Liffarome distinctive
It softens leaf alcohol with fruit and violet leaf: green and grassy, but rounder and less sharp, with a pear note that most violet-leaf materials lack.
How Liffarome is used
Used in traces for natural green effects in floral, fruity and fresh compositions.
Typical role: modifier (used in small amounts to change the character of a blend).
How Liffarome differs from similar materials
- cis-3-Hexenol
- A distributor calls Liffarome a softer member of the leaf-alcohol family; cis-3-hexenol is sharper, plainer grass, Liffarome adds pear and violet leaf. (compared directly by a cited source)
- Undecavertol
- Undecavertol is a piercing, very powerful violet-leaf green; Liffarome is softer and fruitier, with pear.
An asterisk marks a difference that a cited source states directly. The others compare the published descriptions of each material. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
