Short profile

Caramel sweetness and a buttery character dominate, supported by toasted bread, malt and pastry impressions with a secondary liquorice accent. In sweet compositions, its warmth is apparent immediately, while its heart-level role connects fruit notes with a woody foundation. The supplier describes persistent gourmand character during dry-down and rates odour strength at 8/10, with compositional impact at 6/10. A stage-by-stage blotter profile and specific projection measurements are not supplied.

Effect in a formula

Contributes warm, edible sweetness and baked depth to gourmand compositions, while softening the contour of lactonic accords. It can connect a fruity opening to a woody base through the heart of a formula. Vanilla-based structures gain a more developed bakery character that the supplier describes as persisting into dry-down.

Use and dosage

Supplier guidance places warm accents in sweet accords at 0.1–0.3%, with a broader 0.1–1% range for gourmand, baked and lactonic effects. A separate listing gives 2.5% as the average level in perfume concentrate, without explaining its relationship to those lower application ranges. These are formulation references, not IFRA limits; the page does not clarify whether they refer to neat material or the supplied dilution.

No confirmed manufacturer use level for this exact product.

Behaviour and performance

Tenacity: Supplier-reported smelling-strip persistence exceeds 340 hours. The test concentration, solvent and environmental conditions are not specified.

Diffusion, tenacity and note impact are not combined into a single performance score.

Dissolving and diluting

Solvents: DPG is the carrier used for the commercial 10% dilution. The page provides no quantitative solubility data or compatibility information for other solvents.
Working dilution: The supplier offers a 10% preparation in DPG as an easier-to-handle option for formulation work. No separate dilution for olfactory evaluation is specified.
Appearance: The neat product is a crystalline powder with a light yellow colour. Appearance of the 10% DPG preparation is not separately described.

Practical tip: Check chemical identity when sourcing under this trade name: this listing identifies CAS 13494-06-9, or 3,4-Dimethyl-1,2-Cyclopentanedione. The supplier explicitly distinguishes it from CAS 80-71-7, which may be associated with the same trade terminology elsewhere.
