In short
Lavender Aldehyde is 2-isopropyl-5-methyl-2-hexenal, a powerful herbaceous aldehyde. Bedoukian describes hints of cocoa, blueberry, bergamot, clary sage and lavender.
What Lavender Aldehyde smells like
Bedoukian, which sells it as Lavender Aldehyde FCC, describes it as very powerful, natural and diffusive, herbaceous with a hint of cocoa, blueberry, bergamot, clary sage and lavender overtones. The Good Scents Company lists herbal, lavender, woody, green, blueberry and tomato. Arctander, as quoted by Pell Wall Perfumes, called it powerful, herbaceous-resinous and slightly minty with a woody, lavender-like undertone and moderate to poor tenacity.

What makes Lavender Aldehyde distinctive
A lavender-herbal aldehyde that also reads as cocoa powder, which is why it turns up in chocolate accords.
Where the descriptions disagree: Bedoukian stresses cocoa and blueberry; Pell Wall Perfumes lists dirty socks first, and Arctander finds it minty and resinous.
How Lavender Aldehyde is used
Used for herbaceous lavender effects, and in traces for a dry cocoa-powder note in chocolate and gourmand accords.
Typical role: modifier (used in small amounts to change the character of a blend).
How Lavender Aldehyde differs from similar materials
- Spirodecane
- Spirodecane is a wormwood-like herbal note with camphor; Lavender Aldehyde is lavender-herbal with cocoa and blueberry facets.
Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
Formulation considerations
Sold as a mixture of the trans and cis isomers. Descriptions differ between sources; one lists an unpleasant dirty-socks facet.
