Linalool

from €7.80

Premium Synthetic Ingredient for Perfumery

Linalool is a widely used terpene alcohol with a floral-woody odor and a faint citrus undertone. Naturally occurring but industrially produced via synthetic or semi-synthetic methods, it serves primarily as a top-note enhancer, a floral modifier, and a technical blender. Its versatile scent harmonizes with citrus, fruit, spice, and floral materials. Though poor in tenacity, its diffusive freshness brings lift and naturality to a broad spectrum of perfumery styles.

What is Linalool?

Linalool is a terpene alcohol with two chiral forms (R and S), present in over 200 plant species including lavender, rosewood, and citrus fruits. Commercially, it is available as a synthetic or semi-synthetic compound, either isolated from essential oils like Bois de Rose or synthesized via hydration of myrcene, a monoterpene from turpentine sources.

Linalool serves as a building block in perfumery and flavor chemistry, as well as a precursor for vitamin E synthesis. It is a low-boiling, top-note ingredient with limited tenacity but strong initial diffusion. The odor differs subtly between isomers: L-Linalool (from rosewood) is slightly fresher, while D-Linalool (from coriander) leans spicier.

Olfactory Profile & Perfumery Applications

Olfactory Characteristics:

  • Floral, slightly woody

  • Light citrus nuance

  • Subtle creamy quality in dilution

Main Perfumery Roles:

  • Top-note elevation in Muguet, Lavender, and Herbal bases

  • Used in Citrus, Fougère, Chypre, and Aromatic styles

  • Often included in Lilac, Sweet Pea, Apple Blossom, Frangipani, and Peony accords

Common Synergies:

  • Lavender, Bergamot, Geranium, Coumarin

  • Works well with Vanillin and citrus aldehydes

Functionality in Formula:

  • Imparts brightness, openness

  • Smooths transitions in volatile top accords

  • Used at 0.05%–1.5% in fine fragrance; lower in functional applications

Industrial & Technical Uses

Linalool is used widely beyond fine fragrance:

  • Functional Perfumes: Soaps, detergents, and air fresheners (as freshness enhancer)

  • Flavoring: Present in blueberry, grape, cola, and chocolate imitations

  • Fixative Synergy: Vanillin strengthens creamy tones and suppresses off-notes

Linalool also serves as a key intermediate in the synthesis of vitamin E and other aroma compounds (e.g., Linalyl acetate, Linalool oxides).
