Short profile

The initial impression is sweet butter and cream, with a full dairy texture. A restrained caramel warmth accompanies milky softness, while fatty-green shading and a cultured, yogurt-like nuance give the profile more complexity than simple sweetness. The supplier places it in the heart-note range and rates its strength at 6/10 and blend impact at 7/10. Strip persistence is reported as 28 hours, but the page does not describe a distinct dry-down transition or projection over time.

Effect in a formula

Acetoin supplies dairy body and rounds sharp synthetic impressions without a correspondingly heavy effect. In white-floral constructions, particularly tuberose, small additions develop fatty, waxy fleshiness. Gourmand and fruit accords gain depth through toffee-like sweetness, jam-like richness or a fermented inflection, while lactones and sandalwood provide complementary settings for its creamy character.

Use and dosage

The supplier gives 0.5% of the fragrance concentrate as an average use level. Trace additions are suggested for developing waxy, fleshy character in tuberose; no numerical trace range or overdose level is provided. These are formulation guidelines, not an IFRA limit.

No confirmed manufacturer use level for this exact product.

Appearance

Practical tip: For a tuberose reconstruction, begin with a trace addition when the objective is waxy floral flesh rather than an overt dairy accord. For a more explicit milk effect, combine acetoin with lactones.
