In short
Nectaryl is a Givaudan ketone with a fruity, peach and apricot-like note with good tenacity.
What Nectaryl smells like
Nectaryl (Givaudan) is a peach-apricot material that smells lactonic although it is a cyclopentanone, not a lactone. Supplier listings give peach, fruity, apricot and lactonic; The Good Scents Company's Givaudan sample fruity, tropical, lactonic, peach, apricot, oily, waxy, custard and coconut. It is cited as lasting more than 380 hours on a smelling strip. A perfumer on a forum called it a cross between apricot and nectarine, slightly tangy, soft and milky rather than strong.

What makes Nectaryl distinctive
A peach that lasts for weeks on a strip — soft, milky and nectarine-like, without the fattiness of the lactones.
How Nectaryl is used
Used in peach, apricot and fruity floral accords, especially where a lasting, soft stone-fruit note is wanted in the base.
Typical role: modifier (used in small amounts to change the character of a blend).
How Nectaryl differs from similar materials
- gamma-Undecalactone (Aldehyde C-14)
- Aldehyde C-14 is stronger and fattier; Nectaryl is softer, milkier and far longer-lasting.
- Veloutone
- Veloutone adds a lactonic jasmine and a lavender-like touch; Nectaryl is the plainer, creamy stone fruit.
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
More tenacious than many fruity materials.
